You set the temperature to the hottest setting and the air still blows cold or maybe slightly warm. If the heater core is clogged or leaking, it will prevent the proper flow of hot coolant. When this happens, the heater core's performance will suffer, resulting in poor heating inside the vehicle. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/427733ae-273f-4c71-bfac-6a4072e25be8/AdobeStock_169393190.jpeg Symptoms - 6 Symptoms Of A Bad Heater Core You Should NOT Ignore - Foggy windshield The fourth symptom is a foggy windshield. If you notice the windshield gets foggy when driving and no amount of air seems to make it go away, the heater core could be the issue. This can happen if the heater core has developed a leak. The evaporated coolant can travel through the vents and make the windshield foggy. Try wiping the windshield with a cloth, if it’s just smudging instead of wiping clean, it’s time to look into your heater core. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/5d41b468-5596-430a-992b-c9c3a2f820c6/woman-driver-feeling-unpleasant-smell-from-air-con-2023-11-27-05-05-42-utc.jpg Symptoms - 6 Symptoms Of A Bad Heater Core You Should NOT Ignore - a Sweet smell inside the cabin This leads us to the next symptom - noticing a sweet smell inside the cabin. When the coolant is leaking inside the car, youll notice a sweet smell similar to maple syrup. It’s important to fix this issue right away because inhaling the coolant can be harmful to you or other passengers. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/355ec553-b80e-4e64-ac8d-d4346c259b9c/car-engine-2024-10-11-09-56-05-utc.jpg Symptoms - 6 Symptoms Of A Bad Heater Core You Should NOT Ignore - Overheating engine Now low coolant leads to the last symptom - an overheating engine. The purpose of the coolant is to absorb the heat from the engine. If coolant levels drop, it will struggle to absorb the required heat. As a result, the engine will start overheating. https://easyautofix.com/symptoms/e3pw68xbbwr3z46-6rzzz-r4ebe-3tw4r-3lzfk monthly 0.5 2025-01-21 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/85e7bced-c3d9-4876-873e-7c42ad4b6763/AdobeStock_40896088.jpeg Symptoms - No Heat in the Car (The Most Common Causes) - THERMOSTAT A third possible cause could be a faulty thermostat. When the thermostat is stuck open, coolant flows continuously through the radiator, keeping it cool. This cooler coolant then passes through the heater core, causing the air from the vents to feel slightly warm or even cool. You can do a test to see if the thermostat is the culprit. Start your car and wait approximately 15 minutes. This should be plenty of time for the engine to reach the operating temperature. If it doesn't you might have a stuck open thermostat. With a normal operating thermostat, one radiator hose should feel very hot and the other hose should feel warm. If both radiator hoses feel slightly warm or cold to the touch, this could mean you have a stuck open thermostat. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/7abda364-90f7-4a79-bef0-3250c389a642/AdobeStock_236316196.jpg Symptoms - No Heat in the Car (The Most Common Causes) - Heater core The next possible cause is a faulty heater core. The heater core could fail in two different ways. It can either get clogged or start leaking. Both will have poor heating performance. The key difference is that if it’s leaking, you'll see the coolant level begin to drop. With the heater on a max position, a quick test you can do is to carefully touch both heater hoses. If you notice one hose is very hot and the other is cold or slightly warm then you could have a clogged heater core. In this case, you can try flushing it out before replacing it to try to save some money. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/1737352a-c3b4-42ce-a577-b0a20fc1fdee/e.jpg Symptoms - No Heat in the Car (The Most Common Causes) - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://easyautofix.com/symptoms/e3pw68xbbwr3z46-6rzzz-r4ebe-3tw4r monthly 0.5 2024-11-07 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/b297a301-da54-4453-ad73-d5b5f255781b/performance-vehicle-driver-2023-11-27-05-06-31-utc.jpeg Symptoms - 4 Symptoms Of A Bad Control Arm You Should NOT Ignore - STEERING ISSUES Another symptom you might experience is steering problems. While driving, you may notice the vehicle pulling to one side—either to the right, the left, or sometimes even both. This can make it difficult to maintain control, especially at higher speeds. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/44bf0df2-c2b6-4844-bce3-376cdeb6a8ae/AdobeStock_610987933.jpeg Symptoms - 4 Symptoms Of A Bad Control Arm You Should NOT Ignore - UNEVEN TIRE WEAR The last symptom you could experience is uneven tire wear. Normally, tires should wear evenly across their surface. However, if you observe certain areas of the tire being more worn than others, it could be a sign of a failing control arm. Since the control arm is connected to the wheels, any vibrations caused by a failing control arm will transfer to the wheels. This causes the wheels to not properly contact the road while driving, leading to uneven tire wear. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/223d1fef-26dd-42a8-80d6-98706772d7c6/pov-car-driver-hand-on-the-steering-wheel-road-2024-04-01-22-20-42-utc.jpg Symptoms - 4 Symptoms Of A Bad Control Arm You Should NOT Ignore - NOISE OVER BUMPS The first symptom you could experience is hearing clunking or banging sounds when driving over bumps. If the bushings or ball joints become loose, that will create excessive play, causing these clunking sounds to appear. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/d2bee5a5-6c8c-42bd-9b9c-26804493f4b3/AdobeStock_557974383.jpg Symptoms - 4 Symptoms Of A Bad Control Arm You Should NOT Ignore - VIBRATIONS The third symptom of a bad control arm is noticeable vibrations while driving. Loose ball joints or worn bushings in the control arm can lead to excessive play, causing back-and-forth movement that results in vibrations. Since the control arm is connected to the steering knuckle, which links to the tie rods and the steering rack, the vibrations eventually travel to the steering wheel, which is why you might feel them while driving. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/fdcea826-a2ba-4df6-923a-6368d6e9c834/Screenshot+2024-10-04+at+3.58.26%E2%80%AFPM.jpg Symptoms - 4 Symptoms Of A Bad Control Arm You Should NOT Ignore - Make it stand out Location of control arms in a vehicle. https://easyautofix.com/symptoms/e3pw68xbbwr3z46-6rzzz-r4ebe monthly 0.5 2024-10-04 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/419144d3-eeb0-4399-b4e2-08a1e0ff94e9/woman-corrects-makeup-looking-in-the-rearview-mirr-2024-09-23-13-12-04-utc.jpg Symptoms - 5 Symptoms Of Bad Struts You Should NOT Ignore - noise The third symptom is hearing unusual sounds when driving. If you hear clunking sounds when turning the steering wheel left or right, it could be an indicator of loose strut mounts. Also, worn-out struts can make banging sounds when driving over bumps. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/f68ff7b8-6dce-41f0-979a-9cd67ee0232c/AdobeStock_483608605.jpg Symptoms - 5 Symptoms Of Bad Struts You Should NOT Ignore - hydraulic oil leak The next symptom is noticing hydraulic oil leaks. If the seal inside the strut fails, hydraulic oil can leak out and start to drip. When this happens, the struts won’t be able to do their job properly, which eventually will cause them to fail. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/2d58f500-0803-4177-b58a-3ffa6aba017e/woman-driver-hands-on-steering-wheel-inside-car-2023-11-28-04-06-47-utc.jpg Symptoms - 5 Symptoms Of Bad Struts You Should NOT Ignore - bouncy ride The first symptom you might experience is a bouncy ride. If your car's struts are faulty, the springs will experience excessive bouncing, especially when driving over bumps or uneven surfaces. So if you notice your vehicle bouncing more than usual when driving, faulty sturts could be the cause. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/3be9b528-e6cd-4796-bf77-f04cc906570d/2.jpg Symptoms - 5 Symptoms Of Bad Struts You Should NOT Ignore - worn tires The second symptom you might notice is worn tires. If your car has faulty struts, the tires will bounce up and down more than usual as they rotate. As a result, your tires will be worn out unevenly. This condition is also commonly referred to as tire cupping. An easy way to identify this is to run your hand along the tire's treads. If you feel high and low spots, it might be time to look into your struts. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/8a3e94d2-dbae-4a2b-901f-69a65f1bda8c/AdobeStock_290912779.jpg Symptoms - 5 Symptoms Of Bad Struts You Should NOT Ignore - diving when braking The fifth symptom your vehicle could experience is diving forward when braking. When struts start to give out, the spring will become easier to compress. So, if the front of your car dives forward and the back lifts slightly when you hit the brakes, your front struts could be the problem. https://easyautofix.com/symptoms/e3pw68xbbwr3z46-6rzzz monthly 0.5 2024-09-24 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/b4bb6284-fae0-4705-8dcc-68988472e82a/Screenshot+2024-09-06+at+8.57.22%E2%80%AFPM.png Symptoms - 6 COMMON OIL-CHANGING MISTAKES TO AVOID - NOT APPLYING OIL ON TOP OF THE FILTER The third mistake you could be making is not lubricating the gasket of the new oil filter. When you rotate the filter onto the engine, the gasket between the filter and the engine can create friction, which might lead to tearing. A tear in the gasket can result in oil leaking from the engine. That's why it’s crucial to always lubricate the gasket before installing the oil filter. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/3cb92964-b4a4-49d2-a289-f1175cdef3bb/Screenshot+2024-09-06+at+8.57.41%E2%80%AFPM.jpg Symptoms - 6 COMMON OIL-CHANGING MISTAKES TO AVOID - ADDING TOO MUCH The fourth mistake you could be making is adding too much oil. Excess oil can increase pressure within the crankcase, leading to potential leaks. Also, when you overfill the engine, it could cause the oil to start foaming. When this happens, oil won’t be able to lubricate the engine parts as efficiently anymore. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/90eea347-2916-4934-99a6-40c47c4532b3/AdobeStock_295769057.jpg Symptoms - 6 COMMON OIL-CHANGING MISTAKES TO AVOID - ADDING TOO LITTLE The next mistake you could be making is not adding enough engine oil. When you add too little engine oil, all the moving parts in the engine won’t be properly lubricated, leading to increased friction. This wears things down faster, leading to damage. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/1b19af40-1023-4ded-92ba-195ec3f1102f/technician-change-car-oil-filter-under-car-mechan-2023-11-27-04-56-49-utc.jpg Symptoms - 6 COMMON OIL-CHANGING MISTAKES TO AVOID - OVERTIGHTENING THE FILTER The last mistake is tightening the filter too much. It’s best to tighten the filter by hand instead of using any kind of wrenches. Typically, most filters should be tightened by about three-quarters of a turn once the gasket touches the engine. If you overtighten the filter, the next time you change the oil, it will be more of a struggle to take off. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/6bf81b70-a5a6-4771-8bdc-127342db68f6/Screenshot+2024-09-06+at+8.56.23%E2%80%AFPM.png Symptoms - 6 COMMON OIL-CHANGING MISTAKES TO AVOID - NOT PUTTING THE OIL IN THE NEW FILTER The first mistake is not putting oil inside the new filter. When replacing the oil filter, always make sure to fill it up with some oil. This will reduce the amount of time your engine will run without oil pressure. This helps protect engine components from wear and tear, reducing the risk of damage caused by insufficient lubrication. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/459a5c8f-3ce6-4802-9b5a-df5dc0960055/Screenshot+2024-09-06+at+8.56.38%E2%80%AFPM.jpg Symptoms - 6 COMMON OIL-CHANGING MISTAKES TO AVOID - NOT WARMING UP THE ENGINE The next mistake is not warming up your engine before draining the old oil. When oil is cold, it thickens. Thicker oil drains more slowly and might not remove all the residue. By warming up your engine to operating temperature, you’ll ensure that the oil comes out faster and more thoroughly. https://easyautofix.com/symptoms/e3pw68xbbwr3z46 monthly 0.5 2024-09-06 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/f630232c-1ce4-47a6-ad5f-242533a7a9ea/Screenshot+2024-07-31+at+8.39.18%E2%80%AFPM.png Symptoms - Top Reasons Your Car Is Overheating - Faulty Radiator Cap The third cause of engine overheating is a faulty radiator cap. If the gasket on the radiator cap is torn, it allows air to enter the cooling system. Air pockets within the cooling system can lead to engine overheating. Also, a radiator cap that is stuck closed can cause excessive pressure buildup, resulting in leaks in the cooling system which leads to an overheating engine. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/be11ea74-3289-4246-8d78-7233350df971/Screenshot+2024-07-31+at+8.40.09%E2%80%AFPM.png Symptoms - Top Reasons Your Car Is Overheating - RADIATOR The fifth cause of your engine overheating is a clogged radiator. If the radiator is clogged, it will prevent the coolant from flowing properly. If coolant can't pass through the radiator, it will never be able to cool down, increasing heat, to the point where your engine is overheating. If you want to save money, try flushing out the system before buying a new radiator. Also, if the fins are dirty, it can cause overheating by not allowing proper airflow to pass through and take away heat from the coolant. So make sure they're clean of debris. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/d86ad8e3-34fe-48fc-8108-a6af723a791f/Screenshot+2024-07-31+at+8.38.24%E2%80%AFPM.png Symptoms - Top Reasons Your Car Is Overheating - Low Coolant The first cause is your vehicle running low on coolant. For the cooling system to function properly, it's essential to maintain the coolant at the correct level. If you notice the coolant is low, refill it to the proper level. However, if it drops again within a few days or a week, you have a leak. This leak could either be internal or external. Here is a list of possibilities for an internal leak: Torn head gasket Torn intake manifold gasket Cracked cylinder head Cracked engine block https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/caad88cd-0a59-4bbe-8da6-ee44fc7dc638/AdobeStock_40896088.jpeg Symptoms - Top Reasons Your Car Is Overheating - THERMOSTAT The second reason your engine could overheat is a stuck-closed thermostat. When the thermostat valve doesn't open, the coolant keeps circulating through the engine, unable to reach the radiator. The radiator’s job is to cool down the hot coolant. So, if the coolant is unable to reach the radiator, it will get very hot, and cause the engine to overheat. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/ca4ee69a-7a8e-469f-833b-eb3cf329b99e/AdobeStock_165254301.jpeg Symptoms - Top Reasons Your Car Is Overheating - RADIATOR FAN The next reason is a faulty radiator fan. If the radiator fan isn’t working, it won’t be able to cool down the hot coolant in the radiator. This hot coolant then circulates back into the engine, raising the engine’s temperature, which causes it to overheat eventually. If you notice your overheating problem go away at high speeds, then this is most likely the problem since air flow to the radiator increases as you drive. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/34981f29-e36b-4834-b6cb-66f01ff39ff7/AdobeStock_62161341.jpeg Symptoms - Top Reasons Your Car Is Overheating - WATER PUMP The next cause is a faulty water pump. A defective water pump will fail to circulate the coolant throughout the system to cool down the engine. If there’s no coolant flow then the coolant can’t circulate through the radiator to get cooled. This will lead to your engine overheating. https://easyautofix.com/symptoms/yjjypr3ganzghrf monthly 0.5 2024-06-20 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/278ae646-0c4c-4445-b28c-4bc1e9ed3e86/Screenshot+2024-06-19+at+10.22.49%E2%80%AFPM.jpg Symptoms - Vacuum Leak Symptoms (Ultimate Guide) - engine dies right away The third symptom is the engine turns on and dies right away. If the vacuum leak is big enough, it will throw off the air-fuel ratio and cause the vehicle to turn off. If you turn on the car and press down on the gas pedal, you’ll notice the engine can stay on longer because there is more fuel injected when the throttle plate is opened more. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/94b0b1cd-9b03-4aa0-a4bc-95cde05fae5b/sad-driver-holding-his-head-having-engine-problem-2023-11-27-04-56-43-utc.jpg Symptoms - Vacuum Leak Symptoms (Ultimate Guide) - stalling engine This leads to the next symptom - a stalling engine. More specifically the vehicle dies on you when you're at a stop sign or a red light. The same reason applies here, the vacuum leak is so big that it throws off the air-fuel mixture too much, disrupting the combustion process, and causing a stalling engine. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/5405d4a8-eb7f-4bc5-87f8-aeaff03611c9/young-puzzled-woman-driver-standing-near-her-car-w-2023-11-27-05-13-31-utc.jpg Symptoms - Vacuum Leak Symptoms (Ultimate Guide) - hissing noise The second symptom you could be experiencing is hearing a hissing noise. Since there is unwanted air being sucked into the engine, it typically creates a hissing noise. There are times when it sounds louder than others. It just depends on how big the torn part is. You'll be able to hear the vacuum leak better with the hood open while the car is running. On the other hand, if the brake booster is ruptured internally you might be able to hear the vacuum leak inside the car. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/4ce19aea-a90e-488f-af32-7cf0ef4c1669/the-car-on-the-city-highway-evening-night-time-2023-11-27-05-06-31-utc.jpg Symptoms - Vacuum Leak Symptoms (Ultimate Guide) - rough idle The fourth symptom is a rough idle. You will feel the vehicle vibrating and wanting to turn off but it won’t. In some situations the vacuum leak can be small enough to disturb the air-fuel mixture and create misfires but not big enough to make the vehicle turn off. Once the upstream oxygen sensors warm up, they will communicate with the ECM. When this happens the engine control module might inject more fuel into the cylinders. At this point, you’ll notice the RPMs being above a thousand. This might be the reason why your car runs rough when it’s cold and better when it’s warm. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/00ee63fc-5cfe-4cbd-9b82-9cfb069f47df/close-up-view-of-the-car-gauge-2023-11-27-05-32-58-utc.jpg Symptoms - Vacuum Leak Symptoms (Ultimate Guide) - Engine Light The first symptom you could be experiencing is the check engine light on. Some codes related to a vacuum leak could be P0300, P0171, or P0174.

You’ll typically notice this when you go to start your car after it’s been turned off for a while. To paint a better picture in your head, let’s consider the engine’s operation cycle. When it’s on, the oil pump circulates oil throughout the engine. However, once you turn the engine off, any remaining oil that’s at the top will sink into the combustion chamber through the defective valve stem seals. So when you go to start your car, the oil that’s been collecting overnight will burn with the air-fuel mixture, resulting in the blue smoke coming out of the exhaust. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/b61a72c6-fc5b-4c32-93fa-c8cf1c2c65f8/Screen+Shot+2023-12-07+at+8.55.07+PM.jpg Symptoms - 6 SYMPTOMS OF BAD VALVE STEM SEALS - oil traces The next symptom is oil traces in the tailpipe. You can grab a white napkin, and wipe the tailpipe to see if it will pick up any oil. If there’s any, the valve stem seals could be the cause for this. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/666c623e-c36c-470b-9869-f43fb8811dd8/Screen+Shot+2023-12-07+at+8.54.50+PM.jpg Symptoms - 6 SYMPTOMS OF BAD VALVE STEM SEALS - loss of oil The second symptom is a loss of oil. You'll notice that you need to add oil more frequently. This happens because the oil escapes into the combustion chamber where it gets burned off in the process. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/b00473a1-0c37-43cf-83da-1c7b8581ed59/Screen+Shot+2023-12-07+at+8.54.58+PM.jpg Symptoms - 6 SYMPTOMS OF BAD VALVE STEM SEALS - bad smells The third symptom is noticing bad smells. When the oil is burning, it can produce an unpleasant smell. This smell can be best described as a combination of oil and exhaust fumes. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/38e1c4df-be3c-48ee-87e6-647419db8147/Screen+Shot+2023-12-07+at+8.55.27+PM.jpg Symptoms - 6 SYMPTOMS OF BAD VALVE STEM SEALS - engine light The last symptom is an engine light.

Sometimes it might be hard to spot leaks, so I recommend using a leak detector to help you out. https://easyautofix.com/symptoms/639nfbj2acjbbhz monthly 0.5 2023-11-03 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/e44c7cc9-b9cc-44e4-b950-788e00ca29bb/Screen+Shot+2023-11-02+at+9.30.23+PM.png Symptoms - CRANK, NO-START: THE MOST COMMON CAUSES - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/fc72e170-216a-467f-91eb-a07023ea5c7f/Screen+Shot+2023-11-02+at+9.18.26+PM.jpg Symptoms - CRANK, NO-START: THE MOST COMMON CAUSES - Make it stand out A blinking red light indicates that the spark plug produces a spark. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/6888890f-2b6f-4e99-bb29-183bdc75e374/Screen+Shot+2023-11-02+at+9.24.40+PM.png Symptoms - CRANK, NO-START: THE MOST COMMON CAUSES https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/0368e83d-0fe1-4c12-a531-c4d215abd677/Screen+Shot+2023-11-02+at+9.30.41+PM.png Symptoms - CRANK, NO-START: THE MOST COMMON CAUSES - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://easyautofix.com/symptoms/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7-xhwbb-ya3ld-f6yj3-rl88n-9cg5d-4jfpn-8ee66-62cjl-ch7ld-ehdpk-hb6xj-45thd-pzjwp-l8p3n-gwlja-3n5zz-9f9hc-w8l6g-4ycgb-rydk5 monthly 0.5 2023-09-05 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/fdaa08ae-872e-4ce0-b777-5f15fbd9bcc3/Screen+Shot+2022-10-01+at+12.57.27+PM.jpg Symptoms - 6 SYMPTOMS OF A BAD BATTERY - jump-starting the car The fifth symptom is jump-starting the car frequently. If you’re finding yourself in this situation very often it could be an indication of a failing battery. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/408f715d-483b-439c-bfaa-26511eb09a99/AdobeStock_72928058.jpg Symptoms - 6 SYMPTOMS OF A BAD BATTERY - battery corrosion Battery corrosion could occur due to electrolyte leakage or acidic vapors escaping from the battery. Inside the battery, there’s a mixture of water and sulfuric acid that forms an electrolyte solution. When this electrolyte comes in contact with the terminals or cables, it can cause corrosion. In some situations, you may also notice an odd smell. It’s important to note that it’s normal for the battery terminals and cables to corrode over time due to moisture in the air. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/d0656356-1dfd-4ce0-8c38-17825a4203d9/Screen+Shot+2023-09-04+at+12.56.43+PM.jpg Symptoms - 6 SYMPTOMS OF A BAD BATTERY - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/8b11423a-9279-4743-87b5-268872e6b855/Screen+Shot+2022-08-04+at+5.27.35+PM.jpg Symptoms - 6 SYMPTOMS OF A BAD BATTERY - rapid clicking sounds The last symptom of a bad battery is rapid clicking sounds. When attempting to start the car, if you hear rapid clicking sounds and see the dashboard lights flickering, but the engine fails to start, it could be a sign of a bad battery. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/046131da-1d93-469c-a46d-19e65e65e534/DSC_0229.jpg Symptoms - 6 SYMPTOMS OF A BAD BATTERY - engine cranking issues The first symptom is engine cranking issues. If you try to start your car, but the crank seems slower than usual, it could be caused by a bad battery. When the battery starts to wear out or gets old, it won’t be able to provide enough current for the starter to turn the engine. This will result in a slower crank. This can especially be more noticeable during colder months. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/873f04fc-3345-40ff-8df5-0b72aec4a9e6/Screen+Shot+2022-09-30+at+5.39.09+PM.jpg Symptoms - 6 SYMPTOMS OF A BAD BATTERY - decreased electrical power The second symptom of a bad battery is decreased electrical power. A weak battery may result in dimming headlights, dim interior lights, or a weak power output from electrical components like power windows, or radio while the key is in the accessory position. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/64854168-8dea-4ae2-902c-1e39e730f9e9/IMG_7854.jpg Symptoms - 6 SYMPTOMS OF A BAD BATTERY - swollen battery case The next symptom of a faulty battery is a swollen battery case. You’ll notice the battery is larger in size. This could happen due to prolonged overcharging of the battery. Overcharging can cause excessive heat to be generated within the battery. This heat can cause the battery to expand, resulting in it swelling up. https://easyautofix.com/symptoms/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7-xhwbb-ya3ld-f6yj3-rl88n-9cg5d-4jfpn-8ee66-62cjl-ch7ld-ehdpk-hb6xj-45thd-pzjwp-l8p3n-gwlja-gt8ck monthly 0.5 2023-09-05 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/85b4f0ab-c298-438a-bad5-e5a1a473b4d9/Screen+Shot+2023-06-13+at+11.16.08+PM.jpg Symptoms - CAR BURNING OIL? TOP 5 COMMON CAUSES OF AN INTERNAL OIL LEAK - PISTON RINGS The second cause is bad piston rings. When the piston rings wear out, it creates a bigger gap between the cylinder wall and the rings. This allows for more oil to pass through and enter the combustion chamber. In addition, if the oil is not changed regularly, it can cause the piston rings to stick, leading to increased clearance in the cylinder. This too results in the engine oil escaping from the crankcase and into the combustion chamber. This can be prevented by regularly changing the oil. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/b39b7a49-a8dd-4568-8f8f-41a442229f59/Screen+Shot+2023-09-01+at+5.15.54+PM.jpg Symptoms - CAR BURNING OIL? TOP 5 COMMON CAUSES OF AN INTERNAL OIL LEAK - valve stem seals The next cause of burning oil is faulty valve stem seals. The purpose of the valve seals is to prevent oil from flowing past the valves and into the combustion chamber. Gradually, they can begin to deteriorate, causing oil leakage into the combustion chamber. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/99c70b5f-c6cc-4b5b-b677-8928cfea1730/Screen+Shot+2023-09-01+at+5.17.15+PM.jpg Symptoms - CAR BURNING OIL? TOP 5 COMMON CAUSES OF AN INTERNAL OIL LEAK - turbocharger The last cause of burning oil is only applied to vehicles with turbochargers. Inside the turbo, there are seals that help prevent oil leakage. If they get worn out, the oil will escape through them. Resulting in the oil going into the intake system and entering the combustion chamber. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/d5bf5994-728a-4460-804b-84da845fd0ac/Screen+Shot+2023-06-13+at+9.51.26+PM.jpg Symptoms - CAR BURNING OIL? TOP 5 COMMON CAUSES OF AN INTERNAL OIL LEAK - PCV VALVE Let’s start with the first least expensive and most overlooked cause, the PCV valve. The whole purpose of the PCV valve is to recirculate harmful gases from the crankcase into the intake manifold. These gases mix with the air-fuel mixture and get burned off in the combustion chamber. If the PCV valve gets stuck open, vapors and excess oil will be drawn from the crankcase and enter the combustion chamber. This will result in the oil being burned off along with the fuel during combustion. The PCV valve should be replaced every 50,000 miles, but this can vary from car to car. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/b69ba814-c172-4a48-8feb-2deca73c4299/AdobeStock_460921724.jpg Symptoms - CAR BURNING OIL? TOP 5 COMMON CAUSES OF AN INTERNAL OIL LEAK - cylinder walls The third cause is damaged/worn cylinder walls. This can happen due to poor oil lubrication or contaminants in the engine oil, such as dirt or debris. In worse situations, it can happen due to an overheating engine. When the cylinder walls get damaged, it creates an increased clearance between the walls and the piston rings. This clearance allows oil to pass through the gap and enter the combustion chamber during engine operation. Once inside the combustion chamber, the oil mixes with the air-fuel mixture and gets burned off. https://easyautofix.com/symptoms/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7-xhwbb-ya3ld-f6yj3-rl88n-9cg5d-4jfpn-8ee66-62cjl-ch7ld-ehdpk-hb6xj-45thd-pzjwp-l8p3n-gwlja-3n5zz-9f9hc-w8l6g-4ycgb-rbxt4-nagr7-g28k7 monthly 0.5 2023-09-06 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/086e494b-e337-494e-b3e5-37235ebdb4bd/starting-the-car-using-the-starter-cables-2023-03-15-00-50-42-utc.jpg Symptoms - NO CRANK, NO START: THE MOST COMMON CAUSES - Battery The first and most common cause is the battery. If your battery has insufficient charge or is completely drained, it won't have enough power for the starter to turn the engine over. A good way to tell if the battery is causing a no-start condition is when hearing multiple clicks and seeing the cluster lights flicker or dim when attempting to turn on the car. You can try jump-starting your vehicle and see if it will help temporarily. Also, make sure to check for corrosion on the battery connectors, as corrosion will prevent the flow of electricity. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/53771e60-aa4b-4888-8ef2-46cf01ece33e/cable-2022-11-10-18-01-36-utc.jpg Symptoms - NO CRANK, NO START: THE MOST COMMON CAUSES - RELAYS & FUSES The second possible cause is relays and fuses. If any fuses related to the starting system are blown, it may prevent the car from starting. Also, a faulty or corroded starter relay can prevent the power supply to the starter motor. If you have another relay in your car that's similar to the starter relay, you can try swapping them. If the starting issue gets resolved after the swap, then you've found the problem. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/c316015d-2580-4f7a-ac72-01a459e35f02/Screen+Shot+2023-09-01+at+12.10.09+PM.jpg Symptoms - NO CRANK, NO START: THE MOST COMMON CAUSES - ignition switch Let’s move on to the next possible cause, the ignition switch. The ignition switch is responsible for transferring electrical current to the starter motor. If it malfunctions, it can prevent the necessary signal from reaching the starter motor, leading to a situation where the engine fails to crank. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/7f711f4e-ebf7-4836-b516-95632bb2f704/AdobeStock_3808111.jpeg Symptoms - NO CRANK, NO START: THE MOST COMMON CAUSES - antitheft system The next potential cause for a no-crank no-start is a malfunctioning antitheft system. One common feature is an immobilizer system that requires a specific electronic code from the key or key fob to start the engine. If there's a problem with the immobilizer system, it won't recognize the correct code and won't allow the engine to start. If you see the anti-theft light on while turning the key, this could be why you get a no crank no start. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/a1ca94bb-dcd8-4c90-96c4-cb428e699741/AdobeStock_337554186.jpg Symptoms - NO CRANK, NO START: THE MOST COMMON CAUSES - wiring issues/loose connections The sixth potential cause is wiring issues or loose connections. Electrical wiring problems, such as damaged/corroded wires or loose connections, can disrupt the flow of electricity and prevent the engine from cranking. For example, your battery terminals, and starter terminals, or maybe even a ground wire. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/4d9919d3-eafb-40bc-8374-ff7f2f54526b/AdobeStock_134564548.jpg Symptoms - NO CRANK, NO START: THE MOST COMMON CAUSES - seized engine The next symptom is a seized engine. If the engine locks up due to internal damage, it can prevent the starter motor from turning the engine over. In this case, attempting to start the engine will result in a no-crank condition. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/b6a21a0c-ed77-4465-8a86-64ed25a4cee4/Hbf1e84e8941443c8bda103ceb81cf5e7L.png Symptoms - NO CRANK, NO START: THE MOST COMMON CAUSES - Neutral safety switch The third possible cause is a faulty neutral safety switch. Automatic transmissions have a neutral safety switch that prevents the engine from starting when the transmission is not in "Park" or "Neutral." When attempting to start the car, if you see the dashboard lights and radio turn on, but don’t hear a crank, then it could be the neutral safety switch. In some situations, you’ll be able to start your car in the neutral position. If you have a manual transmission, you’ll have a clutch safety switch instead. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/570509f5-6145-4d31-a186-3424bbe4a888/car-spare-parts-car-engine-starter-on-a-white-bac-2022-09-28-23-03-23-utc.jpg Symptoms - NO CRANK, NO START: THE MOST COMMON CAUSES - starter The fifth component that may cause a no crank no start is a faulty starter. The starter motor is responsible for initiating the engine's rotation, allowing the car to start. It can fail due to an internal electrical issue, such as worn brushes or a faulty starter solenoid. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/dcdae02c-ffc6-4c2c-ac39-d7ba434195d5/DSC_0319.JPG Symptoms - NO CRANK, NO START: THE MOST COMMON CAUSES - computer issues The last potential cause is computer system issues. Even though this is not as common, it’s still something to consider. If any of the computers like the ECM or BCM are malfunctioning in your vehicle, they can either send out wrong information or lose communication completely, leaving you with a no-crank, no-start. https://easyautofix.com/symptoms/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7-xhwbb-ya3ld-f6yj3-rl88n-9cg5d-4jfpn-8ee66-62cjl-ch7ld-ehdpk-hb6xj-45thd-pzjwp-l8p3n-gwlja-3n5zz-9f9hc-w8l6g-4ycgb-rbxt4-nagr7 monthly 0.5 2023-09-05 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/8ee95c7c-71f1-4986-9fa6-3fa309f4ce52/Screen+Shot+2023-05-16+at+11.45.16+AM.png Symptoms - 4 SYMPTOMS OF A BAD DIFFERENTIAL - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/eef04c4b-944f-4940-9ec8-0c07a195d9a2/Screen+Shot+2023-05-16+at+11.50.43+AM.jpg Symptoms - 4 SYMPTOMS OF A BAD DIFFERENTIAL - unusual sounds The first symptom of a bad differential is hearing unusual sounds. If you hear grinding, rattling, or in some situations howling noises coming from underneath your car while driving, it could be due to a bad differential. The noise will typically get worse as you increase speed. These sounds could be caused by worn bearings or a damaged ring and pinion gear. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/108fcb2a-1dde-40e0-a6fe-cce508bcdb9f/Screen+Shot+2023-05-16+at+11.51.10+AM.png Symptoms - 4 SYMPTOMS OF A BAD DIFFERENTIAL - fluid leaks The second symptom of a faulty differential is fluid leaks. Fluid may be leaking from a worn-out gasket, a pinion seal, or axle seals. If you notice your car has any of these leaks, it’s important to fix them as soon as possible. If you ignore the leaks, it will lead to more serious issues that we’ll cover in the next symptom. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/5d4b10c0-d6c6-4f94-8022-1e61b2944f4c/Screen+Shot+2023-05-16+at+11.51.40+AM.png Symptoms - 4 SYMPTOMS OF A BAD DIFFERENTIAL - fluid contamination The last symptom of a bad differential is fluid contamination.

If the belt tensioner isn't applying the correct pressure on the belt, it’s going to slip and create a squealing noise. If you hear a grinding noise, it could be caused by grease escaping from the pulley bearings, causing them to dry out and create a noise. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/76ea384e-dfcf-4916-8100-0d809443e777/Screen+Shot+2023-05-16+at+10.45.05+AM.png Symptoms - 4 SYMPTOMS OF A BAD DRIVE BELT TENSIONER - oil leaking The fourth symptom of a faulty drive belt tensioner is oil leaking from the hydraulic tensioner. A loss of fluid will decrease the tensioner’s force on the belt and create similar symptoms we've stated previously. It’s important to note that not all cars have a hydraulic tensioner, so this symptom might not apply to you. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/5d89e526-97a1-40a1-a218-bf9a879b1548/Screen+Shot+2023-05-16+at+10.43.56+AM.jpg Symptoms - 4 SYMPTOMS OF A BAD DRIVE BELT TENSIONER - worn drive belt The second symptom is a worn drive belt. This could be caused by the slipping of the belt due to the lack of pressure coming from the tensioner. In some situations, you might have alternator intermittent issues as a slipping belt can mess with alternator output voltage. If you have the manual type, the fix could be as easy as turning a couple of bolts to adjust the tensioner. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/2180ff2d-7fb2-4e34-bd5d-cc587dd39a9c/Screen+Shot+2023-05-16+at+10.43.26+AM.jpg Symptoms - 4 SYMPTOMS OF A BAD DRIVE BELT TENSIONER - exessive tensioner movement The first symptom of a bad drive belt tensioner is excessive tensioner movement. With the car on, take a look underneath the hood. If you notice the tensioner shaking excessively, it could be due to a weak spring force (spring type) or a fluid leak (hydraulic type). Here's an example of a bad tensioner(spring type), and here's an example of a good one. Make sure to double check the belt tensioner bolts aren't loose as this can cause a similar symptom. https://easyautofix.com/symptoms/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7-xhwbb-ya3ld-f6yj3-rl88n-9cg5d-4jfpn-8ee66-62cjl-ch7ld-ehdpk-hb6xj-45thd-pzjwp-l8p3n-gwlja-3n5zz-9f9hc-w8l6g-4ycgb monthly 0.5 2023-09-05 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/dabb7e85-9214-4fe6-b831-6de64213dc97/Screen+Shot+2023-05-15+at+7.35.45+PM.jpg Symptoms - 4 SYMPTOMS OF A BAD ABS MODULE - The location will typically be on the hydraulic control unit but can vary between cars.

This voltage is transferred into the spark plug to allow it to produce a spark to ignite the air-fuel mixture. However, the ignition coil only operates when instructed by the engine control module. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/6694dd9d-30ab-4213-b33c-e46d309e08a3/Screen+Shot+2023-04-20+at+4.43.32+PM.png Symptoms - DON’T IGNORE THESE 4 SIGNS OF BAD IGNITION COILS - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/4d797412-7cb2-4b6a-b851-cee8f2380846/Screen+Shot+2023-04-20+at+4.53.23+PM.jpg Symptoms - DON’T IGNORE THESE 4 SIGNS OF BAD IGNITION COILS - check engine light The first symptom of a failing ignition coil is an illuminated engine light. When the ignition coil fails to send voltage through the spark plug, it results in a misfire - meaning there won't be any mini-explosions in the combustion chamber. The engine control module (ECM) is quick to pick up on this and will turn on the check engine light to alert the driver. With this OBD2 scanner, you can scan your vehicle for trouble codes. Here are some misfire codes that can pop up: P0300: Random/Multiple Cylinder Misfire Detected P0301: Cylinder 1 Misfire Detected P0302: Cylinder 2 Misfire Detected P0303: Cylinder 3 Misfire Detected P0304: Cylinder 4 Misfire Detected P0305: Cylinder 5 Misfire Detected P0306: Cylinder 6 Misfire Detected P0307: Cylinder 7 Misfire Detected P0308: Cylinder 8 Misfire Detected P0309: Cylinder 9 Misfire Detected P0310: Cylinder 10 Misfire Detected P0311: Cylinder 11 Misfire Detected P0312: Cylinder 12 Misfire Detected As you can see, these codes are correlated with the cylinder that's misfiring, so you can easily identify the problem area. Some vehicles even have specific codes for a faulty ignition coil. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/677af403-91e4-45ec-a06a-898f30a93996/Screen+Shot+2023-04-20+at+4.53.36+PM.jpg Symptoms - DON’T IGNORE THESE 4 SIGNS OF BAD IGNITION COILS - poor performance The next symptom of a faulty ignition coil is poor performance. Your car will feel slower than usual. When an ignition coil fails to send voltage to a spark plug, it creates a misfire, causing the engine to be slower. For optimal engine performance, all cylinders need to ignite the air-fuel mixture to push down the pistons and rotate the crankshaft. If even just one cylinder misfires in a four-cylinder engine, it reduces the engine's efficiency by 25%, resulting in poor performance. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/d408197b-b835-4fed-8e27-aa2cce0b2bf9/Screen+Shot+2023-04-20+at+4.53.43+PM.png Symptoms - DON’T IGNORE THESE 4 SIGNS OF BAD IGNITION COILS - smell of gas The fourth symptom you might experience is the smell of gas. Since the air-fuel mixture isn’t being ignited in the cylinder, the fuel will go through the exhaust and out of the tailpipe. This will create a smell of gas. It’s also important to consider that with time, this excess fuel could go through your catalytic converter and cause it to overheat and get damaged. So it’s important to get this problem fixed right away. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/f41dca5c-cdbe-42e5-b1a2-fb3523f2174e/Screen+Shot+2023-04-20+at+4.43.18+PM.png Symptoms - DON’T IGNORE THESE 4 SIGNS OF BAD IGNITION COILS - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/a789b09a-bb74-47f5-917a-70215379342b/AdobeStock_453410721.jpg Symptoms - DON’T IGNORE THESE 4 SIGNS OF BAD IGNITION COILS - rough idle Rough idle is when your car's engine doesn't run smoothly while it's idling, causing vibrations and shaking. You may feel it in the steering wheel, dashboard, or even your seat. It's a common sign of a failing ignition coil. As mentioned earlier, when an ignition coil fails to send voltage through the spark plug, it creates a misfire. This misfire is the reason why you’re experiencing a rough idle. It's important to note that a rough idle can also be caused by other factors such as a bad idle air control valve, a dirty throttle plate, or even a vacuum leak. So, if you're only experiencing a rough idle, without any other symptoms, it's important to have a professional mechanic diagnose the issue before assuming it's due to a faulty ignition coil. Ignoring the issue could lead to more serious problems down the road, so don't hesitate to get it checked out as soon as possible. https://easyautofix.com/symptoms/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7-xhwbb-ya3ld-f6yj3-rl88n-9cg5d-4jfpn-8ee66-62cjl-ch7ld-ehdpk-hb6xj-45thd-pzjwp-l8p3n-gwlja-3n5zz monthly 0.5 2023-09-05 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/affbd6ae-8416-4924-badd-34889632c0f0/Screen+Shot+2023-04-20+at+7.24.26+PM.png Symptoms - 5 SYMPTOMS OF A BAD FUEL RAIL PRESSURE SENSOR - Typically, the fuel pressure sensor can be found on the fuel rail. If you’re struggling to find the sensor in your vehicle, I would recommend getting a repair manual here. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/af9b4b3b-c9ec-4ba8-a6d6-dcfc883df7a8/Screen+Shot+2023-04-20+at+7.39.42+PM.jpg Symptoms - 5 SYMPTOMS OF A BAD FUEL RAIL PRESSURE SENSOR - poor fuel economy The last symptom is poor fuel economy. If the air-fuel ratio is not optimal, it can directly affect your gas mileage. You may notice that you're visiting the gas station more often than usual or your vehicle isn't getting as many miles per gallon as it normally does. It's either because your engine is using too much fuel when it's not required or not enough fuel is being used, and a faulty fuel pressure sensor can be the culprit behind it all. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/1dbd8056-e250-48bb-9d2a-4ab7511fce86/Screen+Shot+2023-04-20+at+7.39.24+PM.jpg Symptoms - 5 SYMPTOMS OF A BAD FUEL RAIL PRESSURE SENSOR - poor performance The fourth symptom to keep an eye out for is poor performance. If you've noticed that your car is slower than usual, it could be due to a faulty fuel rail pressure sensor. In order for the engine to perform its best, the combustion chambers need to combust at the perfect air-fuel ratio. If air or fuel is disrupted, then your engine’s power will suffer. In this case, if the sensor is faulty, it will trick the ECM and will mess with the air-fuel ratio creating a loss of power. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/de0a95ae-2ead-4f0d-818a-fc9ef9cef952/Screen+Shot+2023-04-20+at+7.22.05+PM.jpg Symptoms - 5 SYMPTOMS OF A BAD FUEL RAIL PRESSURE SENSOR - The purpose of the fuel rail pressure sensor is in the name. It measures the fuel rail pressure and sends it to the ECM. In some situations, this sensor also reads the temperature of the fuel. In simple terms, the fuel rail pressure sensor is used by the ECM (Engine Control Module) to calculate and send a signal to the fuel pump control module to control the speed of the fuel pump. This system is known as the electronic returnless fuel system. Your vehicle might not even have one. Instead, some cars have a fuel pressure regulator. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/a0600b97-73bc-4610-a8a8-2a0e2a4128b5/Screen+Shot+2023-04-20+at+7.38.49+PM.jpg Symptoms - 5 SYMPTOMS OF A BAD FUEL RAIL PRESSURE SENSOR - check engine light The first thing you may notice when your fuel pressure sensor isn't functioning properly is that the engine light will come on. This is because the engine control module can tell that something's not right with the sensor, and it wants to bring it to your attention. To help you diagnose the issue, there are certain codes that are associated with a faulty fuel rail pressure sensor: P0190 P0191 P0192 P0193 P0194 Ensure you can access your car's diagnostic codes by acquiring an OBD2 scanner here. There are times when your sensor may be faulty without triggering the check engine light. That's why it's important to keep an eye out for other symptoms as well. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/2c6ede23-fed7-41f9-9176-ccc2a615e89f/Screen+Shot+2023-04-20+at+7.39.09+PM.jpg Symptoms - 5 SYMPTOMS OF A BAD FUEL RAIL PRESSURE SENSOR - stalling engine Another sign of a bad fuel rail pressure sensor that you could experience is your engine stalling. You’ll notice your vehicle randomly turns off when you’re parked or driving. This is due to the same factor as described in the previous symptom. The sensor gives a false fuel pressure reading, therefore, the ECM thinks it’s making the correct decisions. However, it ultimately gets fooled and ends up disrupting the air-fuel ratio, causing the vehicle to randomly turn off. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/68426c9a-081d-4d05-bd1c-751d7294271e/Screen+Shot+2023-04-20+at+7.39.01+PM.jpg Symptoms - 5 SYMPTOMS OF A BAD FUEL RAIL PRESSURE SENSOR - HARD START The second symptom of a faulty fuel rail pressure sensor is a hard start. You'll notice that the engine takes longer to turn on than usual, even though you can hear the starter cranking. This could be happening because the sensor is giving a false fuel pressure reading to the engine control module. And when the ECM gets the wrong information, it can make an incorrect decision about how to adjust the fuel mixture. As a result, the engine might be running too lean or too rich, making it hard for your vehicle to start. So, if you're having trouble getting your engine to turn over, and you've already checked your battery and starter, then it might be time to take a closer look at your fuel pressure sensor. https://easyautofix.com/symptoms/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7-xhwbb-ya3ld-f6yj3-rl88n-9cg5d-4jfpn-8ee66-62cjl-ch7ld-ehdpk-hb6xj-45thd-pzjwp-l8p3n-gwlja-3n5zz-9f9hc monthly 0.5 2023-09-05 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/c6172426-6788-4c68-8e5e-bcdd02c86050/Screen+Shot+2023-04-23+at+1.30.58+PM.jpg Symptoms - 6 SYMPTOMS OF A BAD THROTTLE BODY - The throttle can be located by following the air intake into the engine as illustrated in the picture. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/f0accfcb-720e-4829-8fff-8a0b88d6cc26/Screen+Shot+2023-04-23+at+1.31.38+PM.jpg Symptoms - 6 SYMPTOMS OF A BAD THROTTLE BODY - limp mode The fifth symptom is your car going into limp mode. Once the engine control module determines the throttle body is not reliable, it will turn on limp mode. Limp mode is a safety feature that protects you and your car. The RPMs and speed will be limited and you’ll be usually stuck in second or third gear. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/23ac66b2-3b14-4f21-a51b-22eb46957a10/Screen+Shot+2023-04-23+at+1.31.08+PM.jpg Symptoms - 6 SYMPTOMS OF A BAD THROTTLE BODY - check engine light The first symptom of a bad throttle body you could be experiencing is an engine light. The engine control module monitors the performance of a throttle body. If it detects a problem with it, the engine light will come on. Here are some codes that may show up : P1121: Throttle Actuator Control Motor Circuit Range/Performance P1122: Throttle Actuator Control Motor Circuit Low P1123: Throttle Actuator Control Motor Circuit High P1124: Throttle Actuator Control Motor Circuit Intermittent P0300: Random Misfires Ensure you can access your car's diagnostic codes by acquiring an OBD2 scanner here. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/280deb5d-0d21-49d5-89ee-33c98946c79d/AdobeStock_472068210.jpg Symptoms - 6 SYMPTOMS OF A BAD THROTTLE BODY - The throttle body is kind of like the mouth of your car's engine. Its job is to control how much air comes in when you press down on the gas pedal. There are two types of throttle body systems: electronic and drive-by cable. The newer cars usually have an electronic system where a motor controlled by the engine control module operates the throttle plate. Whereas in the older cars, you'll find the drive-by cable system where a cable connects the throttle plate to the gas pedal. When you press down on the gas pedal, the cable rotates the throttle plate to allow more air into the engine. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/a2527f47-57ec-4b62-9f42-de35b70e916f/Screen+Shot+2023-04-23+at+1.31.31+PM.png Symptoms - 6 SYMPTOMS OF A BAD THROTTLE BODY - engine stalling The fourth symptom you could experience is your engine stalling. Maybe you notice your car turning off at the stop sign, while you’re parked, or at the red light. This can happen if the throttle plate edges are gunked up with dirt, preventing air from coming into the engine, and resulting in your vehicle turning off. The reason why it turns off when the car is stopped, and not when the car is moving is because the throttle plate is opened up a lot more when the car is in motion. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/5891b1aa-171b-4551-907e-ca4314372aa4/Screen+Shot+2023-04-23+at+1.31.46+PM.jpg Symptoms - 6 SYMPTOMS OF A BAD THROTTLE BODY - Crank but no start The last symptom is a crank but no start. This has personally happened to me. I turned the key to the start position and heard the starter cranking the engine, but it wouldn’t turn on. When diagnosing, I came to the conclusion that the throttle plate was so dirty that it was stuck-closed. This prevents the right amount of air to come into the engine. And if the engine has an incorrect air-fuel ratio, there won’t be combustion to get the engine running. I ended up cleaning the throttle body with a carburetor cleaner and a toothbrush. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/bdd899ba-1c85-428a-8a6e-7da0dc848025/Screen+Shot+2023-04-23+at+1.31.24+PM.jpg Symptoms - 6 SYMPTOMS OF A BAD THROTTLE BODY - High/rough idle The third symptom is your car idling rough or high. In the beginning stages of the throttle body going bad, you’ll notice your vehicle shaking while it’s in the stopped position. This happens because the dirt accumulates around the throttle plate. This prevents the correct amount of air to come into the engine and throws off the air-fuel mixture, which could also result in misfires. Once the engine control module notices a problem with the throttle body, it’s going to open up the throttle plate a tad bit to allow more air to come in. You will notice your RPMs will usually be higher than 1000 when you’re parked or at the stop sign. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/1d0c0959-e1ce-4684-9e46-9493fca21989/Screen+Shot+2023-04-23+at+1.31.16+PM.jpg Symptoms - 6 SYMPTOMS OF A BAD THROTTLE BODY - VEHICLE HESITATION The second symptom of a faulty throttle body is your vehicle hesitating to move. This could happen if the motor that’s responsible for rotating the plate is starting to go out. A weaker motor will result in a slower response rate when you press down on the gas pedal. Another reason could be dirt on the throttle plate, which will cause it to get stuck. https://easyautofix.com/symptoms/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7-xhwbb-ya3ld-f6yj3-rl88n-9cg5d-4jfpn-8ee66-62cjl-ch7ld-ehdpk-hb6xj-45thd-pzjwp-l8p3n-gwlja-3n5zz-9f9hc-5w2jx monthly 0.5 2023-05-15 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/d7faa393-b9b8-4c7e-b20b-cc7b8fc2560b/Screen+Shot+2023-04-26+at+1.25.22+PM.jpg Symptoms - 5 SYMPTOMS OF A BAD TIE ROD - vibration while driving The second symptom of a bad tie rod that you could be experiencing is vibration while driving. You’ll feel the vibration get worse as you drive. This can happen if the tie rods start to wear out, creating a back-and-forth motion when driving. In some situations, you might encounter steer wander. Meaning, your car pulls to the left or the right on its own. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/a84745c7-b368-4976-8756-444b6cc06d89/AdobeStock_267536344.jpeg Symptoms - 5 SYMPTOMS OF A BAD TIE ROD - uneven tire wear Another sign of a bad tie rod is uneven tire wear on your front tires. Specifically, some areas of the tire may become more worn out than others. Worn tie rods can create a back-and-forth motion in the steering system, causing the tires to wobble slightly and leading to uneven wear over time. This issue will only worsen the longer you continue driving with faulty tie rods, which can ultimately cause more significant damage to your tires and suspension components. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/0c5c60fa-2fac-43c8-a28a-b7d2aafa1f58/Screen+Shot+2023-04-26+at+1.25.13+PM.jpg Symptoms - 5 SYMPTOMS OF A BAD TIE ROD - steering wheel freeplay When tie rods start to go bad, the first symptom you may notice is play in the steering wheels. This means that you can turn the steering wheel a few inches before the wheels actually begin to move. Typically, this occurs when the inner or outer tie rods wear out internally, causing a larger gap in the socket than there should be. In addition to the steering wheel freeplay, you may also experience shaking in the steering wheel when driving over bumps or rough roads. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/74ee49a0-84c0-48f1-acca-53da2ad56a79/AdobeStock_328833215+%281%29.jpeg Symptoms - 5 SYMPTOMS OF A BAD TIE ROD - ruptured rubber casing The fourth symptom of a bad tie rod is a ruptured rubber casing. When this happens the grease escapes allowing dirt and moisture to enter. This prevents the tie rods from working properly. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/5e89ed5b-4be6-4b00-8d5b-50ea86b2a29d/Screen+Shot+2023-04-26+at+1.25.30+PM.jpg Symptoms - 5 SYMPTOMS OF A BAD TIE ROD - clunking noise The last symptom of a bad tie rod is hearing a clunking noise. You’ll be able to hear it when turning your vehicle left or right. Clunking noise can appear if either the inner or outer tie rods are worn out. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/eecc2ed3-61b2-4353-a02e-4a5faeabf589/OUTER+TIE+ROD.jpg Symptoms - 5 SYMPTOMS OF A BAD TIE ROD - The inner tie rods are attached to the rack and pinion steering mechanism located near the center of the vehicle's front axle. On the other hand, the outer tie rods connect to the steering knuckle situated right behind each wheel. https://easyautofix.com/symptoms/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7-xhwbb-ya3ld-f6yj3-rl88n-9cg5d-4jfpn-8ee66-62cjl-ch7ld-ehdpk-hb6xj-45thd-pzjwp-l8p3n-gwlja-3n5zz-9f9hc-w8l6g monthly 0.5 2023-09-05 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/560937f2-3bfe-41e4-bb3d-dd2d25f67e76/Screen+Shot+2023-04-26+at+5.31.50+PM.jpg Symptoms - 4 SYMPTOMS OF A BAD KNOCK SENSOR - POOR PERFROMANCE The second symptom of a faulty knock sensor is poor engine performance. You’ll feel a lack of acceleration and your vehicle will overall be slower. A bad knock sensor reading can trick the engine control module to believe that there is a detonation, which will lead to the ECM changing the ignition timing when it’s not needed. This will cause poor combustion efficiency. In some situations, the ECM can purposely limit you to a certain speed to protect your vehicle if it senses the knock sensor is dysfunctional. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/03663a21-fa88-46c8-8ebb-a9859367b973/Screen+Shot+2023-04-26+at+5.32.03+PM.jpg Symptoms - 4 SYMPTOMS OF A BAD KNOCK SENSOR - knocking noise The last symptom is a knocking noise. Some people describe it as a metallic noise while the engine is running. Again, the purpose of the knock sensor is to detect unwanted detonations and relay the information to the ECM to change the ignition timing to fix the issue. Therefore, if the sensor is failing, the engine control module won’t be able to know exactly when to change the ignition timing. This will result in unwanted detonations in the combustion process. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/5db26c03-790c-4666-bced-b0a3dec51f3e/Screen+Shot+2023-04-26+at+5.31.57+PM.jpg Symptoms - 4 SYMPTOMS OF A BAD KNOCK SENSOR - Poor fuel economy The third sign of a faulty knock sensor is poor fuel economy. Leading back to the previous example, since combustion efficiency decreases when the ECM changes the ignition timing, this will cause poor gas mileage. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/583dcc56-60f2-425e-8a14-d396766b50cf/Screen+Shot+2023-04-26+at+5.31.35+PM.jpg Symptoms - 4 SYMPTOMS OF A BAD KNOCK SENSOR - The purpose of the knock sensor is to send a signal to the ECM (engine control module) when it senses unwanted vibrations in the engine. For example, if there is an engine knock which basically means there's a mini detonation after the spark plug ignites, the knock sensor will read this vibration, create an AC voltage and send it to the ECM. Then, the ECM will try to prevent this from happening again by retarding the ignition timing. In other words, changing when the spark plug ignites the air-fuel mixture. This helps prevent serious damage to your engine. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/736a8214-c9ec-45fa-8fc0-ecd69b906cdd/Screen+Shot+2023-04-26+at+5.31.42+PM.jpg Symptoms - 4 SYMPTOMS OF A BAD KNOCK SENSOR - check engine light The first symptom of a bad knock sensor is having your check engine light on. If the ECM senses something wrong with the knock sensor these codes may pop up: P0324 P0325 P0326 P0327 P0328 P0329 P0330 P0331 P0332 P0333 P0334 Ensure you can access your car's diagnostic codes by acquiring an OBD2 scanner here. https://easyautofix.com/symptoms/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7-xhwbb-ya3ld-f6yj3-rl88n-9cg5d-4jfpn-8ee66-62cjl-ch7ld-ehdpk-hb6xj-45thd-pzjwp-l8p3n-gwlja-3n5zz-9f9hc-fgamx monthly 0.5 2023-05-15 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/dbeb1396-8e19-4243-93fd-ba57dac40519/Screen+Shot+2023-04-26+at+6.57.51+PM.png Symptoms - 4 SYMPTOMS OF A BAD IGNITION SWITCH - car won’t turn off The fourth symptom of a bad ignition switch is your car won’t turn off. You could be pulling up in your parking lot, turning your key to the off position, and taking it out only to notice your car is still on. This isn’t very common but it’s definitely possible if the switch is defective. If you’re in this situation and want to turn your vehicle off, just unplug the fuel pump fuse. This will prevent your fuel pump from turning on and delivering fuel to your engine. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/d65a14e3-f510-4366-9dda-20451dbf8ba1/Screen+Shot+2023-04-26+at+6.57.35+PM.png Symptoms - 4 SYMPTOMS OF A BAD IGNITION SWITCH - Car turning off while driving The second symptom of a faulty ignition switch is your car turns off while driving. A defective switch can prevent power from going into the control modules leaving your vehicle brainless. Control modules are critical for your car since they monitor sensors and command when to add a spark and inject fuel at the perfect time to keep your car running. A quick way to test the ignition switch is to try wiggling the keys back and forth while the engine is on in the park position. If it dies, then it could be the switch. I’ll link a perfect video that resembles this in the description below. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/c2b90eb4-7787-4098-8d27-bfb9aea7270d/Screen+Shot+2023-04-26+at+6.25.21+PM.png Symptoms - 4 SYMPTOMS OF A BAD IGNITION SWITCH - The purpose of the ignition switch is to send or cut battery voltage to a specific group of components depending on the position that your keys are in. Now, there are 4 possible positions. The first one is the lock or off position, which basically means that your battery is going to cut power to most electrical circuits. The second position is going to turn on the accessories in your car such as the radio and dashboard lights. The third position will send power to the control modules like the ECM, BCM, TCM, and more. The last position will provide power to the starter motor and will also alert the ECM to command fuel and spark to start the combustion process, or in other words, it will start your car. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/091b1542-4ae2-4cc8-aa21-9a04df36838b/Screen+Shot+2023-04-26+at+6.57.45+PM.png Symptoms - 4 SYMPTOMS OF A BAD IGNITION SWITCH - accessory problems The third symptom is having accessory problems. With the car on in the park position, you could be experiencing your dash lights turning on and off rapidly. On the flip side, with the car off, on the accessory position, you could be experiencing nothing turning on at all. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/be1f56ef-f16e-490a-8c8d-fc685ed09f80/Screen+Shot+2023-04-26+at+6.29.50+PM.jpg Symptoms - 4 SYMPTOMS OF A BAD IGNITION SWITCH - The ignition switch will be located behind the ignition lock cylinder https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/e8eeb792-4be5-4737-b248-45226517c793/Screen+Shot+2023-04-26+at+6.57.27+PM.jpg Symptoms - 4 SYMPTOMS OF A BAD IGNITION SWITCH - No crank no start The first and most common symptom of a bad ignition switch is a no crank no start. This could happen if there’s no contact inside the switch to be able to send electrical current from the battery to the starter to get it cranking. In some situations, your vehicle can start for a bit, and then die seconds after. https://easyautofix.com/symptoms/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7-xhwbb-ya3ld-f6yj3-rl88n-9cg5d-4jfpn-8ee66-62cjl-ch7ld-ehdpk-hb6xj-45thd-pzjwp-l8p3n-gwlja-3n5zz-ebfpk monthly 0.5 2023-05-15 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/6710ed20-2220-4a76-a341-652b66aee2fe/Screen+Shot+2023-04-27+at+5.06.46+PM.png Symptoms - 5 SYMPTOMS OF A BAD VOLTAGE REGULATOR - dead battery The third symptom you may experience is a dead battery. If you find yourself needing to replace your battery earlier than expected, it may be due to an issue with the voltage regulator. This can happen if the voltage regulator is overcharging the battery. Specifically, anything over 15V can damage it. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/51060cea-59d3-48de-9410-99b85b8ffcf9/Screen+Shot+2023-04-27+at+5.07.03+PM.png Symptoms - 5 SYMPTOMS OF A BAD VOLTAGE REGULATOR - headlight problems The fourth symptom of a bad voltage regulator is having headlight problems. You may notice your headlights increase in brightness as you accelerate or on the flip side you may notice them more dim than usual. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/81acd863-f455-4cc7-9ad7-7db617b155f3/Screen+Shot+2023-04-27+at+5.01.48+PM.jpg Symptoms - 5 SYMPTOMS OF A BAD VOLTAGE REGULATOR - The voltage regulator prevents the battery from either undercharging or overcharging. This ensures that your car battery remains charged enough to start your vehicle and prevents any potential harm to the battery caused by overcharging. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/5aa66577-0681-4e7b-a83b-78a0bfff31cc/Screen+Shot+2023-04-27+at+5.04.02+PM.jpg Symptoms - 5 SYMPTOMS OF A BAD VOLTAGE REGULATOR - In most cars, the location of the voltage regulator is either attached to the alternator or inside of it. In older cars with carburetors, it could be found on the firewall. Also, some newer cars don't have a voltage regulator. Instead, the alternator voltage is controlled by the engine control module. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/6035cf75-8dff-4ff4-941c-024ad11db673/Screen+Shot+2023-04-27+at+5.06.28+PM.png Symptoms - 5 SYMPTOMS OF A BAD VOLTAGE REGULATOR - warning lights The first symptom of a faulty voltage regulator is the illumination of warning lights on the dashboard. More specifically, the battery light will come on. However, in certain cases, other warning lights such as SRS, TCS, ABS, or BRAKE may also illuminate. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/b436f640-c0a2-4c84-9767-39405f966f27/Screen+Shot+2023-04-27+at+5.18.22+PM.png Symptoms - 5 SYMPTOMS OF A BAD VOLTAGE REGULATOR - discharged battery The second symptom of a bad voltage regulator is a discharged battery. You’ll be trying to turn on your car but it will fail to start. This can be caused by the voltage regulator limiting the amount of voltage needed to charge the battery. Resulting in the battery not having enough power for the starter to crank your engine and start your car. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/0219e89a-e7e6-4c9a-a155-c4ac8b1edabe/Screen+Shot+2023-04-27+at+5.07.15+PM.png Symptoms - 5 SYMPTOMS OF A BAD VOLTAGE REGULATOR - blown fuses The fifth symptom of a bad voltage regulator you could be experiencing with your car is blown fuses. A bad voltage regulator can cause the alternator to overcharge the battery, leading to an increase in the voltage. According to Ohms's law (voltage/resistance = amperage), as voltage increases, so does amperage. And if the amperage exceeds what the fuse is rated for, the fuse will blow. https://easyautofix.com/symptoms/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7-xhwbb-ya3ld-f6yj3-rl88n-9cg5d-4jfpn-8ee66-62cjl-ch7ld-ehdpk-hb6xj-45thd-pzjwp-l8p3n-gwlja-3n5zz-ebfpk-yzfwz monthly 0.5 2023-05-15 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/6bbd7ff6-d3c2-4050-b382-abe732c47441/Screen+Shot+2023-04-27+at+5.57.46+PM.png Symptoms - IS YOUR CAR SHAKING WHEN STOPPED? 3 COMMON CAUSES OF A ROUGH IDLE - dirty throttle plate The second potential cause for a rough idle is a dirty throttle plate. When you press down on the gas pedal, the throttle plate opens up to allow more air to come in. However, at idle, the throttle plate is just slightly open to let a small amount of air come in. Over time, there can be build-up around the throttle plate, which can restrict the airflow. This causes the air/fuel mixture to become imbalanced, and as a result, your car could have a rough idle. You might notice that your vehicle is vibrating or shaking when it's idling. Fortunately, cleaning the throttle plate is a relatively EasyAutoFix. You can use a carburetor cleaner to clean the throttle plate and restore proper airflow. This can help smooth out your car's idle and improve its overall performance. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/9450d6dd-f484-4d15-97ff-1870f278bb46/Screen+Shot+2023-04-27+at+5.46.39+PM.png Symptoms - IS YOUR CAR SHAKING WHEN STOPPED? 3 COMMON CAUSES OF A ROUGH IDLE - idle air control valve The first potential cause for a rough idle is a clogged or stuck-closed idle air control valve. This little valve is responsible for controlling the amount of air that enters your engine while your car is idling, or in other words stationery. However, not all cars have one, especially the newer models. They use an electronic throttle body to open up a tad bit while idling to control the air coming in. When the idle air control valve gets clogged or stuck-closed, it restricts the airflow needed for efficient combustion. In order for proper combustion to occur, the engine strives to achieve the perfect air-fuel ratio. A faulty idle air control valve restricts the correct amount of air needed, throwing off the air-fuel mixture and causing combustion issues that create a rough idle. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/ae970e37-3524-47b6-86aa-889f4a87be91/Screen+Shot+2023-04-27+at+6.00.04+PM.jpg Symptoms - IS YOUR CAR SHAKING WHEN STOPPED? 3 COMMON CAUSES OF A ROUGH IDLE - vacuum leak The third potential cause for a rough idle is a Vacuum leak. If you’re not sure what a vacuum leak is, in simple terms, it’s the air that enters the engine (marked with blue arrows in the picture) that is not noticed by the mass air flow sensor or the manifold absolute pressure sensor. These sensors are used by the engine control module to read the correct amount of air coming into the engine. The goal is to make the air-fuel ratio the best it can be, and these sensors are crucial to achieving that. Now, when there is air entering the engine that isn't being noticed by the engine control module, then that’s when the rough idle starts to occur. This extra air entering the engine disrupts the air-fuel mixture, leading to a poor running engine. The reason why a vacuum leak will affect the vehicle more in idle vs while it's moving is because at idle the throttle plate is open less, so the ECM commands less fuel. As a result, the difference between air and fuel is greater. On the flip side, when the vehicle is moving, the throttle plate is open more so the ECM commands more fuel. This is why you feel your car performs better when it's moving, and rough when it's idling. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/50dbfa33-6683-4203-9c56-d941916c137e/Screen+Shot+2023-04-27+at+5.49.55+PM.jpg Symptoms - IS YOUR CAR SHAKING WHEN STOPPED? 3 COMMON CAUSES OF A ROUGH IDLE - The location of the idle air control valve will be near the throttle body.

If the transmission fluid level is low, there may not be enough lubrication, causing increased friction and heat within the transmission. This increased friction can cause the gears to grind against each other, making it difficult to shift gears smoothly or causing them to slip out of gear altogether. The transmission system may also not be able to create enough hydraulic pressure, causing difficulty in shifting gears. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/3024fce2-554a-4109-a746-10a330a43795/Screen+Shot+2023-04-27+at+6.49.51+PM.png Symptoms - 5 SYMPTOMS OF LOW TRANSMISSION FLUID YOU NEED TO KNOW - burning smell Since low transmission fluid levels can overheat the transmission, it will cause a burning smell that may be noticeable inside the car. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/6d392472-6d93-4ee9-a70b-ad1328e59f32/Screen+Shot+2023-04-27+at+6.27.40+PM.jpg Symptoms - 5 SYMPTOMS OF LOW TRANSMISSION FLUID YOU NEED TO KNOW - The location of the transmission fluid level dipstick varies depending on the make and model of the vehicle. In most vehicles, the transmission fluid dipstick is located underneath the hood near the back of the engine. However, some newer vehicles don't have a dipstick to check the fluid level. For example, my Ford Fusion has an oil leveling plug hole on the side of the transmission. In simple terms, the fluid level needs to be even with the plug hole, if it's not, your car is low on fluid. If you’re not sure where to locate the plug hole in your vehicle I would recommend using a repair manual. It's also important to note that some manufacturers require a special procedure or tool in order to check the fluid level. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/816e07e6-f0ed-4e53-9f89-793dcf3abae3/Screen+Shot+2023-04-27+at+6.45.58+PM.png Symptoms - 5 SYMPTOMS OF LOW TRANSMISSION FLUID YOU NEED TO KNOW - warning lights Some vehicles may have a dedicated transmission warning light that illuminates when the fluid level is low or when the fluid is overheating. In contrast, other vehicles may have an engine warning light that activates when the transmission fluid is low, as the engine control module communicates with the transmission control module. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/4d0c8f4b-fe62-4ffb-86ce-dc37f08066ec/Screen+Shot+2023-04-27+at+6.49.48+PM.png Symptoms - 5 SYMPTOMS OF LOW TRANSMISSION FLUID YOU NEED TO KNOW - overheating transmission As the transmission's parts rub against each other without enough ATF to lubricate them, they create more friction.

You could hear growling, rumbling, or humming sounds. They will typically get louder as you increase speed. The sound will be coming from the wheel that has a defective wheel bearing. An easy way to figure out which bearing is affected is by driving and turning the steering wheel at the same time. For example, if you turn the steering wheel to the right and the noise gets louder, this could mean the wheel bearing on the left side of the front wheel is defective. This is because the weight of the vehicle is transferred to the left side when turning to the right. This creates more pressure for the defective wheel bearing to handle. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/d7faa393-b9b8-4c7e-b20b-cc7b8fc2560b/Screen+Shot+2023-04-26+at+1.25.22+PM.jpg Symptoms - 4 SYMPTOMS OF A BAD WHEEL BEARING - loose steering wheel The second symptom of a bad wheel bearing is a loose steering wheel. If the wheel bearing wears out, it’s gonna create an excessive play in that specific wheel. This is why the steering wheel will feel loose when turning left or right. It will also get worse when you drive over rough surfaces such as bumpy roads. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/04cd5718-0078-43b4-833d-84cebd055638/Screen+Shot+2023-05-04+at+5.39.12+PM.jpg Symptoms - 4 SYMPTOMS OF A BAD WHEEL BEARING - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/cbba9bb9-74a7-40e7-aca4-3354168d2e70/Screen+Shot+2023-05-04+at+6.03.50+PM.png Symptoms - 4 SYMPTOMS OF A BAD WHEEL BEARING - steering wheel vibrations The third symptom of a faulty wheel bearing is feeling vibrations in the steering wheel. This symptom will get worse as you increase speed. The cause for this is a worn-out wheel bearing that makes the wheels wobble as you’re driving. Since the wheels are connected to the tie rods, and the tie rods are connected to the steering rack, the vibrations will be felt in the steering wheel. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/e2b507b3-a825-42b2-919f-29842563a29d/Screen+Shot+2023-05-04+at+6.03.57+PM.png Symptoms - 4 SYMPTOMS OF A BAD WHEEL BEARING - abs light The last symptom of a faulty wheel bearing is having the ABS light on. This occurs in some vehicles because the ABS sensor is attached to the wheel hub assembly, which houses the wheel bearings. When the bearings go out, it can cause the ABS light to come on. https://easyautofix.com/symptoms/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7-xhwbb-ya3ld-f6yj3-rl88n-9cg5d-4jfpn-8ee66-62cjl-ch7ld-ehdpk-hb6xj-45thd-pzjwp-l8p3n-gwlja-3n5zz-ebfpk-9g46j monthly 0.5 2023-09-05 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/b3a6b01e-360e-4666-8f6b-a6b173943eea/Screen+Shot+2023-05-04+at+8.27.50+PM.png Symptoms - 4 SYMPTOMS OF A BAD HEAD GASKET - overheating engine The second symptom is an overheating engine. You'll notice the temperature gauge climbing up, and in worse situations, the engine will start smoking. This can happen if the head gasket is torn, allowing the coolant to transfer from the passages into the combustion chamber, where it gets burned off in the process. If you keep having to refill your coolant but don’t see an external leak, this could be the reason why. On the flip side, the head gasket could be torn from the edge, allowing coolant to leak externally. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/a8d223d4-ce1d-43df-9bf3-6813e18bb716/Screen+Shot+2023-05-04+at+8.34.45+PM.png Symptoms - 4 SYMPTOMS OF A BAD HEAD GASKET - thick white smoke The third symptom is thick white smoke coming from the tailpipe. This happens when coolant moves into the combustion chamber. This will create thick white smoke, sending it down to the exhaust manifold and out the tailpipe. It’s important not to confuse this with the white smoke that comes out when it's cold outside. This is a process of condensation and is totally normal. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/52f5a029-5850-4bdb-95c8-c916389c5965/Screen+Shot+2023-05-04+at+8.34.53+PM.png Symptoms - 4 SYMPTOMS OF A BAD HEAD GASKET - poor performance The fourth symptom is poor performance. Your car will be a lot slower than usual. In some situations, you’ll also get a check engine light with misfire diagnostic codes. This happens when the head gasket is torn and unable to hold the compression for the combustion chamber. Compression is super important for the engine to perform its best. Without it, your car will be at a loss of power. Ensure you can access your car's diagnostic codes by acquiring an OBD2 scanner here. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/faaffc09-c2f0-4669-9f06-283bf3552b50/Screen+Shot+2023-05-04+at+8.27.34+PM.png Symptoms - 4 SYMPTOMS OF A BAD HEAD GASKET - MIXTURE OF OIL & COOLANT The first symptom of a bad head gasket you could be experiencing with your car is a mixture of oil and coolant. You’ll notice a cappuccino color on the dipstick. In some situations, you might also see a milky substance when removing the engine cap or coolant cap. This happens when the head gasket is torn, leaking coolant into oil passages or vice versa. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/45da447e-8338-4376-80a8-df803f5c7b1f/AdobeStock_319996067.jpeg Symptoms - 4 SYMPTOMS OF A BAD HEAD GASKET - The location of the head gasket will be between the engine block and the cylinder head.

If your car has drum brakes, it won’t have brake calipers, it will have a wheel brake cylinder, instead. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/e357152d-14fa-4951-ab1a-e09b70cb63f8/Screen+Shot+2023-05-04+at+10.04.42+PM.jpg Symptoms - 5 SYMPTOMS OF A BAD BRAKE CALIPER - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/4e8eaa4c-51b1-4ade-9a83-b28e80914aa6/Screen+Shot+2023-05-05+at+1.57.50+PM.png Symptoms - 5 SYMPTOMS OF A BAD BRAKE CALIPER - CAR PULLING TO ONE SIDE The second symptom of a faulty brake caliper is your car pulling to one side when driving. This happens when the caliper piston or caliper sliding pins are seized either on the right or the left side of the front wheels. As a result, the brake pads will be in friction with the rotor at all times. The rotor that’s affected will get very hot. In some situations, you might even see it smoking. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/83093070-0c36-4d93-91c4-bef91e5aab8b/Screen+Shot+2023-05-05+at+2.00.43+PM.jpg Symptoms - 5 SYMPTOMS OF A BAD BRAKE CALIPER - poor BRAKE performance The fourth symptom of a bad brake caliper is poor brake performance. You’ll be pressing down on the brakes, but it will take the vehicle longer to stop than usual. The brake pedal will also feel soft or spongy. This happens due to the brake fluid escaping from the caliper piston seal. When you press down on the brake pedal, your vehicle will be losing fluid, therefore, the hydraulic force won’t be as strong. And as a result, your car will have poor brake performance. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/3da24b5e-fb11-4b4a-9c7e-6631eabe3e49/Screen+Shot+2023-05-05+at+2.00.16+PM.jpg Symptoms - 5 SYMPTOMS OF A BAD BRAKE CALIPER - LEAKING BRAKE FLUID The third symptom you could be experiencing is leaking brake fluid. You’ll notice that the brake reservoir will be low on fluid. There will also be a fluid leak underneath the tires. These leaks can be coming from the caliper bleeder skew or the piston seal. If you see that the brake caliper is in good condition, you can just replace the seal and the dust boot to save some money, instead of buying new calipers. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/6b86651f-4e81-4b23-ae29-32a874a57cca/Screen+Shot+2023-05-05+at+1.57.32+PM.jpg Symptoms - 5 SYMPTOMS OF A BAD BRAKE CALIPER - DRAGGING BRAKES The first symptom of a bad brake caliper is dragging brakes. It will feel as if someone is holding down the brakes slightly. This is caused by a faulty rear caliper piston that is constantly engaged. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/028194de-1be4-44f2-b979-62d98e235c79/Screen+Shot+2023-05-05+at+2.01.16+PM.png Symptoms - 5 SYMPTOMS OF A BAD BRAKE CALIPER - UNEVEN BRAKE PAD WEAR The fifth symptom is uneven brake pad wear. When replacing your brake pads, you’ll see one side of the brake pad more worn down than the other. This can be caused by a caliper that has more than 1 piston. If one of the pistons locks up, this will cause the brake pad to tilt and create uneven brake pad wear. Also, if one of the sliding pins is locked up it could cause uneven brake pad wear, as well. https://easyautofix.com/symptoms/badbrakecaliper-hcs6m monthly 0.5 2023-05-15 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/ec930591-403b-4258-8cbf-385258a0f5cb/Screen+Shot+2023-05-08+at+8.15.19+PM.jpg Symptoms - 5 SYMPTOMS OF BAD BRAKE PADS - strange sounds The first and most common symptom of bad brake pads that people experience is hearing a squealing or grinding noise. If you hear a squealing noise while driving or braking, it could mean that the brakes have worn down to the wear indicator. This will cause the wear indicator to rub against the rotor. On the other hand, if you hear a grinding noise when braking, it could be due to a worn-down brake pad. This will cause the backing plate to rub against the rotor. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/fa26016a-e5c9-4e95-bf41-5b36f828c254/Screen+Shot+2023-05-08+at+7.20.21+PM.jpg Symptoms - 5 SYMPTOMS OF BAD BRAKE PADS - The brake pads will be behind the wheel in between the rotor and the caliper. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/177918dd-b5c7-47a8-b4aa-e49b4e1f0c27/Screen+Shot+2023-05-08+at+8.15.26+PM.png Symptoms - 5 SYMPTOMS OF BAD BRAKE PADS - longer braking distance The third symptom you could be experiecning is a longer braking distance. If the the brake pads are worn down to the backing plate, the metal to metal contact won’t provide the same stopping power as the brake pad lining. In some situations, you’ll experience vibrations when braking. It’s important to note that a warped rotor could also cause this when braking. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/f3458a66-5e15-4a53-8546-370c2a70ae31/Screen+Shot+2023-05-08+at+8.12.15+PM.jpg Symptoms - 5 SYMPTOMS OF BAD BRAKE PADS - brake warning light The fifth symptom of bad brake pads is a brake warning light. Some cars have an electrical wear indicator that turns on the brake warning light whenever the brake pad lining wears down. When the indicator touches the rotor it grounds itself to complete the circuit and turn on the brake warning light. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/ec4670df-7147-4f54-87c0-77f116ee7860/Screen+Shot+2023-05-08+at+7.16.52+PM.jpg Symptoms - 5 SYMPTOMS OF BAD BRAKE PADS - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/8e6a13c6-30ea-4979-8b2b-8051fc32a579/Screen+Shot+2023-05-08+at+8.11.34+PM.jpg Symptoms - 5 SYMPTOMS OF BAD BRAKE PADS - scratched rotor The second symptom of bad brake pads is a scratched rotor. This happens when the backing plate is used to press on the rotors to stop the car. This metal-to-metal contact creates visual damage to the rotor. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/dcabf6c9-9cfb-490e-8a7e-9990478935fa/Screen+Shot+2023-05-08+at+8.15.32+PM.jpg Symptoms - 5 SYMPTOMS OF BAD BRAKE PADS - car pulling to one side The fourth symptom of bad brake pads is your car pulling to one side when braking. For example, if the brake pads are completely worn out on the right side of the vehicle, then the braking force will be applied on the left side. This causes the vehicle to pull to the left side when braking. If this happens to your car, make sure to diagnose and inspect the brake system carefully as there could be other failing components involved. https://easyautofix.com/symptoms/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7-xhwbb-ya3ld-f6yj3-rl88n-9cg5d-4jfpn-8ee66-62cjl-ch7ld-ehdpk-hb6xj-45thd-pzjwp-l8p3n-gwlja-3n5zz-9f9hc-5w2jx-bmbfp-g4sc4 monthly 0.5 2023-09-05 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/036a9e2f-488d-41d2-952b-f645db104036/AdobeStock_193504031.jpeg Symptoms - 4 SYMPTOMS OF A BAD CV AXLE - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/dfbd4709-bbe8-4334-8ec2-ffa986da468c/Screen+Shot+2023-05-08+at+9.50.22+PM.png Symptoms - 4 SYMPTOMS OF A BAD CV AXLE - leaking cv axle boot The third symptom of a bad cv axle is a leaking cv axle boot. You’ll usually find grease spilled on the inner portion of the tires, suspension parts, and on the ground. When this happens, dirt, moisture, and debris enter the damaged portion of the boot and prevent it from working properly. In some situations, if you don’t hear clicking noises when turning and catch a tiny leak early on, you can just order the boot with grease and repair that portion to save some money from buying the whole thing. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/29559ae8-8adf-4a18-8e7c-7bc281a4cb87/Screen+Shot+2023-05-08+at+9.48.26+PM.jpg Symptoms - 4 SYMPTOMS OF A BAD CV AXLE - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/845901f9-570f-43e7-954b-93c83d9100e3/Screen+Shot+2023-05-08+at+9.56.36+PM.png Symptoms - 4 SYMPTOMS OF A BAD CV AXLE - vibrations The fourth symptom is vibration while driving. If you chose to ignore the symptoms over time the cv axle will get worse and start creating a vibration when driving. This is caused by internal damage of the cv joint. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/d7faa393-b9b8-4c7e-b20b-cc7b8fc2560b/Screen+Shot+2023-04-26+at+1.25.22+PM.jpg Symptoms - 4 SYMPTOMS OF A BAD CV AXLE - clicking noise The second symptom of a bad cv axle is hearing a clicking noise when driving and turning at the same time. Depending on the way you turn, you can tell which CV axle is affected. If you turn left and hear the clicking noise but not when turning right then its probably the cv axle on the left side of the car. This usually happens when the outer cv joint is faulty. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/b814e12c-2e39-4da7-9fa0-69c9089cc5d1/Screen+Shot+2023-05-08+at+9.50.04+PM.png Symptoms - 4 SYMPTOMS OF A BAD CV AXLE - clunking noise The first symptom you might experience with your car is hearing a clunking noise when accelerating.

In older cars with carburetors, it could be found on the firewall. Some newer cars don't have a voltage regulator, instead, the alternator voltage is controlled by the engine control module (ECM). If you're having trouble finding it, here is an excellent car repair manual. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/8433df49-2798-44fe-9a53-f2e0e4d35885/Screen+Shot+2023-05-09+at+8.28.03+PM.png Symptoms - 5 SYMPTOMS OF A BAD VOLTAGE REGULATOR - blown fuses The last symptom you could be experiencing with your car is blown fuses. A bad voltage regulator can cause the alternator to overcharge the battery, therefore, increasing the voltage. According to Ohms's law (voltage/resistance = amperage), as voltage increases, so does amperage, and if amperage exceeds what the fuse is rated for, the fuse will blow. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/8d5e191c-afe1-4414-98c8-de51ae2f9363/Screen+Shot+2023-05-09+at+8.27.01+PM.png Symptoms - 5 SYMPTOMS OF A BAD VOLTAGE REGULATOR - discharged battery The second symptom is a discharged battery. You’ll be trying to turn on your car only to find out it won’t start. This can be caused by the voltage regulator limiting the amount of voltage needed to charge the battery. This results in the battery not having enough power for the starter to crank your engine and start your car. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/1c57e230-e945-4c42-86b6-e32de40e7c03/Screen+Shot+2023-05-09+at+8.27.56+PM.png Symptoms - 5 SYMPTOMS OF A BAD VOLTAGE REGULATOR - headlight problems The fourth symptom of a bad voltage regulator is having headlight problems.

You could have multiple codes that have to do with the BCM and the circuits it controls. However, the most common code when the BCM goes bad is the U0140 code, which means there's no communication with the BCM. Make sure there are no torn wires or corroded connectors, as these can also cause this code to appear. Ensure you can access your car's diagnostic codes by acquiring an OBD2 scanner here. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/717dcec7-e8b9-4dc7-8e97-4e094cb08ebe/Screen+Shot+2023-05-10+at+3.48.13+PM.jpg Symptoms - 4 SYMPTOMS OF A BAD BODY CONTROL MODULE (BCM) - accessory failure The second symptom is the accessories not working as they should. The non-working accessories can vary from car to car. Here are some examples that could happen. For instance, you turn on your high beam lights, and your windows roll down. Or you turn on your left turning signal and the car honks as well. Basically, since the BCM does not work properly, any electrical accessory in your vehicle can act strangely and dysfunctional. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/13ee562b-83f2-45eb-9d2e-4a90f025af38/Screen+Shot+2023-05-10+at+3.48.21+PM.jpg Symptoms - 4 SYMPTOMS OF A BAD BODY CONTROL MODULE (BCM) - only certain accessories working The third symptom of a faulty BCM is only certain accessories working.

If you have a leak or a clog in the EVAP system, the fuel tank pressure sensor will read the pressure difference. When that happens, ECM (engine control module) will illuminate the check engine light. Having the light on will automatically fail your emissions test. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/81273ef8-d5c3-4926-bd7c-c94a8222c3a3/Screen+Shot+2023-05-10+at+5.46.49+PM.jpg Symptoms - 4 SYMPTOMS OF A BAD EVAP CANISTER - gas pump issues The second symptom of a faulty charcoal canister is the gas pump keeps shutting off while fueling. You’ll be putting gas in your car and with just 1 or two dollars it clicks and turns off as if it was a full tank. This can happen if the canister is clogged, increasing the fuel vapor pressure. Which is why your pump keeps turning off. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/bd2c96d5-bf50-4f73-85c6-9af9581637ca/Screen+Shot+2023-05-10+at+5.47.00+PM.jpg Symptoms - 4 SYMPTOMS OF A BAD EVAP CANISTER - fuel smell The last system of a bad EVAP canister symptom is noticing a fuel smell.

If the electrical current doesn’t reach the brake lights they wont be able to turn on. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/f31f07ce-deab-4c44-bfa4-60162adf2cd8/Screen+Shot+2023-05-10+at+9.45.30+PM.png Symptoms - 6 SYMPTOMS OF A BAD BRAKE LIGHT SWITCH - brake light don’t turn off On the flip side, the third symptom is the brake lights staying on all the time. This can happen if the switch is shorted internally. Another reason could be the brake light switch stopper fell off. Not having the stopper will make the switch always stay closed, sending an electrical current to the brake lights at all times. Make sure to get this fixed right away as this can be the reason why your battery is dead the next day. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/3b363240-3d3a-483d-b7ee-e8f35e6fc70e/Screen+Shot+2023-05-10+at+9.45.44+PM.png Symptoms - 6 SYMPTOMS OF A BAD BRAKE LIGHT SWITCH - no start The fourth symptom is the car wont start. This only applies to cars with a push-button start system since it only works when it detects the brake pedal is applied. A faulty brake switch won’t be able to signal the push button start system when the brake pedal is depressed, leaving you with a no-start. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/26c22ea2-2fb9-478c-b9f5-d43f1a4e71d1/Screen+Shot+2023-05-10+at+9.46.04+PM.png Symptoms - 6 SYMPTOMS OF A BAD BRAKE LIGHT SWITCH - stuck in park The last symptom is your car stuck in park. You’ll be pressing down on the brake pedal trying to shift from park to reverse but it seems to be stuck. Most people don’t know this, however, when you press down on the brake pedal it sends a signal to activate the shift interlock solenoid to allow shifting out of park. This is a safety feature. The problem is when the brake switch isn’t working, there won’t be a signal going to the shift interlock solenoid.

For instance, the 2014 Jeep Cherokee had a huge problem with this. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/cb922032-3033-4782-a923-e7edacfdcaa0/H6a5f0dc783bf4058b5d76dd7d75869bfl.jpg Symptoms - 4 SYMPTOMS OF A BAD TRANSMISSION CONTROL MODULE (TCM) The purpose of the transmission control module (TCM) is to monitor sensors inside the transmission and communicate with the engine control module to be able to shift at the perfect time. The TCM also alerts the vehicle with diagnostic codes if something is wrong. The reason why a transmission control module can act up could be due to torn wires, a software issue, internal corrosion, cracks, or even a loose mounting bracket that creates unwanted vibrations. If you have a manual transmission, don’t worry about it because your car doesn’t have a TCM. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/447e74d2-abc9-4634-8512-87fc2b64328d/Screen+Shot+2022-11-21+at+4.33.02+PM.png Symptoms - 4 SYMPTOMS OF A BAD TRANSMISSION CONTROL MODULE (TCM) - UNPREDICTABLE SHIFTING The second symptom your car could have is unpredictable shifting. You’ll be driving down the road, increasing RPMs, and noticing your vehicle is either shifting too early or too late. It might also feel like a hard shift. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/ae47f7b7-e308-4ad1-8d00-d33a224fd193/Screen+Shot+2022-11-21+at+4.33.10+PM.jpg Symptoms - 4 SYMPTOMS OF A BAD TRANSMISSION CONTROL MODULE (TCM) - poor fuel economy The third symptom of a bad TCM is poor fuel economy. In order for the engine to run its best, the transmission control module has to command the gears to shift at the perfect time. If the TCM is inconsistent with shifting gears, then it’s going to make the engine work harder than it needs to. And as a result, you’ll be spending more time at the gas station than usual. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/b475df65-b93f-4f2a-8690-855b555e6016/Screen+Shot+2022-11-08+at+5.38.09+PM.jpg Symptoms - 4 SYMPTOMS OF A BAD TRANSMISSION CONTROL MODULE (TCM) - engine light The first symptom of a bad transmission control module is having the check engine light on. Some codes that might pop up are: P0613 P0700 P0706 Ensure you can access your car's diagnostic codes by acquiring an OBD2 scanner here. https://easyautofix.com/symptoms/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7-xhwbb-ya3ld-f6yj3-rl88n-9cg5d-4jfpn-8ee66-62cjl-ch7ld-ehdpk-hb6xj-45thd-pzjwp monthly 0.5 2023-09-05 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/28a327d6-b2bb-4dbd-bdf2-f290991242b0/Screen+Shot+2022-11-18+at+12.32.51+PM.jpg Symptoms - 5 SYMPTOMS OF A BAD WATER PUMP - heater not warming up The fifth symptom of a bad water pump is noticing the heater not warming up. The heater in your car works by having hot coolant going through the heater core, which transfers hot air inside the car by a blower motor. If the water pump fails, it will never be able to circulate coolant to the heater core, resulting in poor heating performance. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/14849f2b-2950-4d5c-905c-62c6eb518bda/Screen+Shot+2022-11-18+at+12.32.29+PM.jpg Symptoms - 5 SYMPTOMS OF A BAD WATER PUMP - check engine light The first symptom of a bad water pump is having the check engine light on. You won’t get a code specifically for a bad water pump, since most water pumps are mechanical. However, you might retrieve a P0217, indicating that the engine is overheating (engine overheat condition). This code could pop up if the ECT (engine coolant temperature sensor) senses the engine coolant temperature getting too hot. Ensure you can access your car's diagnostic codes by acquiring an OBD2 scanner here. You can still have a faulty water pump with no check engine light so let's move on to the next symptom. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/24b8ad8f-a7ac-4ed4-b8d5-71b9acb7c757/Screen+Shot+2022-11-18+at+12.27.51+PM.png Symptoms - 5 SYMPTOMS OF A BAD WATER PUMP - Leak from the weep hole The second symptom of a bad water pump is noticing a leak coming from the weep hole. When the seals inside the water pump start to fail, the coolant will leak past them and go out of the weep hole. The weep hole was designed to let you know that the water pump is starting to go bad. There have been instances where after-market water pumps leak from the weep hole. That’s why I recommend using OEM (original equipment manufacturer) to save you time and money. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/9e9cdc8d-1626-4974-ad01-eec9a851d3b0/Screen+Shot+2022-11-18+at+12.32.44+PM.jpg Symptoms - 5 SYMPTOMS OF A BAD WATER PUMP - WHINING sound The fourth symptom of a defective water pump is hearing a whining noise. This happens when the bearings inside the water pump start to fail or the pulley attached to the water pump is loose. This will create a back-and-forth motion, creating a whining noise. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/2c6262b2-1039-4606-a9dd-658d3b649574/Screen+Shot+2022-11-18+at+12.32.21+PM.jpg Symptoms - 5 SYMPTOMS OF A BAD WATER PUMP - The water pump will usually be located behind the timing chain cover or outside of the engine near the serpentine belt. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/1092c530-c555-4e6c-b54c-e5f305693f86/Screen+Shot+2022-11-18+at+12.32.36+PM.jpg Symptoms - 5 SYMPTOMS OF A BAD WATER PUMP - overheating engine The third symptom your car could be experiencing is the engine overheating. You’ll notice the temperature gauge on hot or in worse situations, you might see smoke coming out of the engine. This could happen if the water pump fails to circulate the coolant throughout the system to cool down the engine. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/7ef23183-e443-4235-8061-45a8c3eaba1f/Screen+Shot+2022-11-18+at+12.14.10+PM.jpg Symptoms - 5 SYMPTOMS OF A BAD WATER PUMP The purpose of the water pump is to circulate coolant throughout the cooling system. https://easyautofix.com/symptoms/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7-xhwbb-ya3ld-f6yj3-rl88n-9cg5d-4jfpn-8ee66-62cjl-ch7ld-ehdpk-hb6xj-45thd monthly 0.5 2022-11-21 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/62923924-baea-4b82-adcd-08267b7b82dc/Screen+Shot+2022-11-15+at+6.58.59+PM.jpg Symptoms - 5 SYMPTOMS OF A BAD STEERING RACK - Fluid leak The first symptom is a power steering fluid leak. You could notice a fluid leak on the driveway when you back out, or maybe you always need to add more fluid to your reservoir, as it’s always low. The leak could be coming from worn-out seals. Below you can find the locations where the leak could be coming from. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/480b00c7-5ae7-4d05-b695-4d1aba75e3d2/Screen+Shot+2022-11-15+at+6.57.20+PM.jpg Symptoms - 5 SYMPTOMS OF A BAD STEERING RACK - The steering rack will be located in the middle between the front wheels. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/8fa64539-5f1f-4c92-9848-f3d4d6a491a0/Screen+Shot+2022-11-15+at+6.53.47+PM.png Symptoms - 5 SYMPTOMS OF A BAD STEERING RACK The purpose of the steering rack is to convert rotational movement from the steering wheel into the side-to-side movement to pivot your wheels left and right. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/5d038f2d-0f79-4adc-b5b6-f22620be5670/Screen+Shot+2022-10-24+at+2.15.03+PM.jpg Symptoms - 5 SYMPTOMS OF A BAD STEERING RACK - loose steering wheel The fourth symptom your car could be experiencing is a loose steering wheel. There could be a dead spot, meaning that you turn the steering wheel but the tires don’t turn. This could happen due to the excessive wear between the pinion and the rack. Some systems have an adjustment screw that can help solve this problem. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/aaac1788-215e-41a9-a513-445cf0cadc63/Screen+Shot+2022-11-15+at+7.07.26+PM.png Symptoms - 5 SYMPTOMS OF A BAD STEERING RACK - grinding noise The third symptom of a faulty steering rack is hearing a grinding noise when turning. If the steering rack starts to leak, there will be more metal-on-metal contact between the rack and the pinion. This will increase friction and eventually lead to a grinding noise in your car. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/034cb35f-10d9-46b9-8df5-e0d319d109b3/Screen+Shot+2022-11-15+at+7.02.24+PM.png Symptoms - 5 SYMPTOMS OF A BAD STEERING RACK - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/93c091ca-d1cc-4581-8ef8-7324ec7a0f16/Screen+Shot+2022-11-15+at+7.10.19+PM.jpg Symptoms - 5 SYMPTOMS OF A BAD STEERING RACK - sTEERING WANDER The fifth symptom of a bad steering rack is steering wander. You could be driving on the highway when all of a sudden your car starts turning in one direction without your control. This could be caused by the excessive wear between the rack and the pinion. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/9dc6dc20-6645-4b0e-9085-03a31ebd5ef1/IMG_2290.jpg Symptoms - 5 SYMPTOMS OF A BAD STEERING RACK - tight steering wheel The second symptom of a bad steering rack is a tight steering wheel. You might notice that you need to apply more force than usual to turn the wheel left or right. This could be caused by the power steering leak. The leak reduces fluid pressure, preventing the right amount of hydraulic force to move the rack from side to side. https://easyautofix.com/symptoms/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7-xhwbb-ya3ld-f6yj3-rl88n-9cg5d-4jfpn-8ee66-62cjl-ch7ld-ehdpk-hb6xj-f629k monthly 0.5 2023-09-05 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/10fcfa39-fb1e-484c-8b93-110f4ce87911/IMG_0935.JPG Symptoms - 5 SYMPTOMS OF A BAD FUEL PUMP - Crank but no start The second symptom you might be experiencing is a crank but no start. You try to turn on your car and you hear a crank, meaning the starter is working properly to turn the engine. However, it won’t do anything because there isn’t enough fuel being pressurized in the system due to a defective fuel pump. In order for a car to start, it needs air, fuel, and a spark to start the combustion process. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/6fc670e5-2fde-41a0-a91b-af9019712a18/Screen+Shot+2022-11-14+at+2.23.58+PM.jpg Symptoms - 5 SYMPTOMS OF A BAD FUEL PUMP - For most cars, the fuel pump will be located inside the gas tank. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/937660b1-5638-4422-ab56-8f1620722c1e/Screen+Shot+2022-10-19+at+4.56.09+PM.jpg Symptoms - 5 SYMPTOMS OF A BAD FUEL PUMP - stalling engine The fifth symptom is your engine stalling. You might be driving on the highway and your engine randomly turns off. Or you could be like me, turning in an intersection and having your car turn off right in the middle, leading to an awkward staring contest. Well, thankfully the car turned back on and I went on my way. This could happen due to the lack of fuel being pressurized into the engine. Too much air and a lack of fuel coming from the fuel pump will cause multiple misfires to the point where your engine will stop turning. This will leave you with a stalling engine. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/5a1bbafb-48dd-4296-ac0c-8985cd9fdfba/IMG_1785.jpg Symptoms - 5 SYMPTOMS OF A BAD FUEL PUMP - loss of power The fourth symptom is a loss of power. You could be pressing down on the gas pedal to increase the speed, but you can’t go as fast as you used to. Maybe at times, it feels like your engine is stuttering to increase speed. The reason for this is due to the lack of pressurized fuel coming from the fuel pump. Whenever the pedal is pressed down, the throttle plate opens up and brings in more air. When more air is increased, the ECM should be adding more fuel, meaning the fuel pump will need to keep up with the demand. A weak fuel pump will fail to keep up with the demand of air, leaving you with a lean condition. This is why your car is losing power. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/1c76f2e9-6ebc-4c0c-9363-b92a17911669/AdobeStock_51457736.jpg Symptoms - 5 SYMPTOMS OF A BAD FUEL PUMP The purpose of the fuel pump is to transfer fuel from the fuel tank into the injectors, where they spray into the engine to mix with air and spark to create combustion. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/1dabe7bc-dd25-49dd-b31f-a684a2f3f6ec/IMG_1367.JPG Symptoms - 5 SYMPTOMS OF A BAD FUEL PUMP - engine light The first symptom of a bad fuel pump is having the check engine light on. You might get a P0087 or P0190 code. Both of these codes indicate a lack of fuel pressure. It’s important to note that these codes are only triggered if your car has a fuel pressure sensor. Your car might not even have one so you won’t see the codes mentioned. However, you might get a P0171 for a lean condition. This means there's more air than fuel ratio in the combustion process. A lean condition is also known to cause multiple misfires, so you could retrieve a P0300, as well. Ensure you can access your car's diagnostic codes by acquiring an OBD2 scanner here. You can still have a faulty fuel pump with no check engine light, so let’s move on to the next symptom. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/e9573cbf-f31e-4bc4-8867-7627747a741b/Screen+Shot+2022-10-24+at+2.59.07+PM.jpg Symptoms - 5 SYMPTOMS OF A BAD FUEL PUMP - long crank The third symptom is a long crank (before starting). This can happen if the fuel pump is not completely dead yet but is starting to go bad. If the fuel pump starts getting weaker, the fuel transfer will take longer to pressurize the system. This will result in a longer crank before start-up. https://easyautofix.com/symptoms/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7-xhwbb-ya3ld-f6yj3-rl88n-9cg5d-4jfpn-8ee66-62cjl-ch7ld-ehdpk-mzjpm monthly 0.5 2023-09-05 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/f7958f1b-438e-4a33-a8a9-269e042b46d2/Screen+Shot+2022-11-08+at+5.38.29+PM.jpg Symptoms - 5 SYMPTOMS OF A BAD ACCELERATOR PEDAL POSITION SENSOR - limp mode The fourth symptom you might be experiencing is your car going into limp mode. Limp mode is a safety feature that protects you and your car. Your car will be a lot slower, the RPMs and speed will be limited, and you’ll usually be stuck in second/third gear. Your safety could be at risk if the accelerator pedal position sensor fails because it’s responsible for communicating data to the ECM (engine control module) to open or close the throttle plate while driving. That’s why limp mode gets activated in your vehicle. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/6d9ab3ac-d8e5-47e1-92ff-5d25911b94c7/Screen+Shot+2022-11-08+at+5.38.20+PM.jpg Symptoms - 5 SYMPTOMS OF A BAD ACCELERATOR PEDAL POSITION SENSOR - poor acceleration The third symptom of a bad accelerator pedal position sensor is poor acceleration. You won’t be able to accelerate as fast as usual because the pedal position sensor isn’t communicating to the ECM (engine control module) to make the proper commands to open up the throttle plate. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/b475df65-b93f-4f2a-8690-855b555e6016/Screen+Shot+2022-11-08+at+5.38.09+PM.jpg Symptoms - 5 SYMPTOMS OF A BAD ACCELERATOR PEDAL POSITION SENSOR - engine light The first symptom of a bad accelerator pedal position sensor is having a check engine light on.

You’ll be pressing down on the pedal but your car only moves seconds after. This happens due to the accelerator sensor not being able to detect the exact position of the gas pedal. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/a55d50e1-1e1c-4124-9871-909f84f95c37/SIX_34B83874-7590-487D-939E-6C9371B24214.jpg Symptoms - 5 SYMPTOMS OF A BAD ACCELERATOR PEDAL POSITION SENSOR The purpose of the accelerator pedal position sensor is to measure the position of the pedal as it’s being pressed down. This information is then used by the ECM (engine control module) to command the electronic throttle body to open up and allow air to come in. This is known as a drive-by-wire system, which most modern cars have. If you have an older car, you’ll most likely have a drive-by cable system. (video below of 2000 Toyota Camry). https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/d3844194-f271-474e-b7c2-92355d512634/Screen+Shot+2022-11-08+at+5.38.36+PM.jpg Symptoms - 5 SYMPTOMS OF A BAD ACCELERATOR PEDAL POSITION SENSOR - unresponsive gas pedal The fifth symptom you could be experiencing is not getting a response when pressing down on the gas pedal. This happens when the accelerator pedal position sensor completely gives out. There have been instances where drivers are on the road and the accelerator stops reacting, so they are forced to pull over. This is why it’s super important to fix the problem right away before letting it build up and get to that point. https://easyautofix.com/symptoms/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7-xhwbb-ya3ld-f6yj3-rl88n-9cg5d-4jfpn-8ee66-62cjl-ch7ld-ehdpk-4444c monthly 0.5 2023-09-05 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/eaa32bac-9dac-44d7-b98a-2af70761588d/Screen+Shot+2022-09-30+at+5.39.18+PM.png Symptoms - 7 SYMPTOMS OF A BAD FUEL PRESSURE REGULATOR - Poor gas mileage The third symptom of a faulty fuel pressure regulator is poor gas mileage in your car. You might be catching yourself spending more time at the gas station than usual. This is due to the extra fuel being sucked into the intake manifold using more gas than what is needed. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/b363ae36-47d7-4278-a8f5-527dad922bad/Screen+Shot+2022-09-22+at+5.01.21+PM.png Symptoms - 7 SYMPTOMS OF A BAD FUEL PRESSURE REGULATOR - rough idle The fourth symptom you could be experiencing with your vehicle is a rough idle. A thrown-off air-fuel ratio causes the combustion process to not burn efficiently, leaving you with unwanted vibrations. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/6e5c7976-53a1-4d67-b8e2-d0f5eca0ab53/Screen+Shot+2022-11-04+at+5.09.24+PM.jpg Symptoms - 7 SYMPTOMS OF A BAD FUEL PRESSURE REGULATOR The purpose of the fuel pressure regulator is to maintain the proper amount of pressure in the fuel system so that the injectors release the right amount of fuel to achieve the perfect air-fuel ratio. A way a vacuum pressure regulator could go bad is by having a torn diaphragm (check out the image below). This will allow fuel to be sucked up by the vacuum hose, going into the engine, creating a rich condition. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/cfa5f8b9-8ca0-4490-bb1d-86d587962e20/Screen+Shot+2022-09-12+at+4.04.15+PM.png Symptoms - 7 SYMPTOMS OF A BAD FUEL PRESSURE REGULATOR - Failed emissions test The sixth symptom that could happen is your car failing the emissions test. The unneeded extra fuel creates more harmful emissions, which go into the catalytic converter and out the tailpipe. The catalytic converter will try to convert some of these harmful gases into safer ones but it won’t be able to do all of it since it’s overloaded resulting in your vehicle failing the emissions test. It’s also extremely important to fix the problem right away to prevent carbon blockage on your catalytic converter and oxygen sensors. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/eca1df40-4d94-4ab3-a2f8-3cb90c9a62b2/IMG_0645.jpg Symptoms - 7 SYMPTOMS OF A BAD FUEL PRESSURE REGULATOR - engine light The first symptom of a bad fuel pressure regulator is an engine light. There won’t be a direct code for the regulator we’re talking about today since it’s vacuum operated. However, you might get some codes that can steer you in the right direction. A code that can pop up is P0172 (rich condition). This means that the engine has more fuel than air ratio.

If you keep driving with a torn diaphragm, over time excess fuel will cause carbon built-up on the spark plugs, preventing them from igniting the air-fuel ratio, leaving you with a hard start or a no start at all. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/586ef757-093a-4974-8953-3c580892f994/phonto+6.jpg Symptoms - 7 SYMPTOMS OF A BAD FUEL PRESSURE REGULATOR - A fuel pressure regulator will typically be located at the end of the fuel rail. On most multiport fuel injection systems. Some can be around the throttle body or other versions can be near the fuel pump. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/c36a0860-bd8e-46e1-a8c0-c7f9dcfa9f43/Screen+Shot+2022-11-04+at+7.35.54+PM.jpg Symptoms - 7 SYMPTOMS OF A BAD FUEL PRESSURE REGULATOR - fuel inside the vacuum line The second symptom of a bad fuel pressure regulator is having fuel inside the vacuum line that connects the regulator to the intake manifold. A good working regulator should never have fuel leaking from the vacuum port or the lines. This is due to the regulator diaphragm being torn. This goes hand and hand wit the next symptom. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/1bdbb93f-dbd5-424c-a916-81ee9f973237/Screen+Shot+2022-10-24+at+2.58.56+PM.png Symptoms - 7 SYMPTOMS OF A BAD FUEL PRESSURE REGULATOR - poor engine performance The fifth symptom of a malfunctioned fuel pressure regulator is overall poor engine performance. In order for the engine to run its best, it needs to burn at the perfect air-fuel ratio, which is 14.7 air to 1 gasoline. Unwanted fuel being sucked from the regulator diaphragm into the intake manifold disrupts the perfect air-fuel ratio, leaving you with a poor running engine. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/4bd1b1be-a7f5-4eff-8720-79573ff07825/SIX_66E2FBD6-055F-4137-B302-B0E7EDC7D1FE.jpg Symptoms - 7 SYMPTOMS OF A BAD FUEL PRESSURE REGULATOR - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://easyautofix.com/symptoms/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7-xhwbb-ya3ld-f6yj3-rl88n-9cg5d-4jfpn-8ee66-62cjl-ch7ld-ehdpk-abr86 monthly 0.5 2023-09-05 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/314c818f-c231-4fc4-839b-132a7de1aca0/Screen+Shot+2022-11-01+at+8.27.41+PM.jpg Symptoms - 4 SYMPTOMS OF A BAD AC PRESSURE SWITCH - Compressor not turning on The second symptom of a bad AC pressure switch is noticing the compressor not turning on. You'll notice the clutch not engaging at all. As mentioned earlier, the purpose of the pressure switch is to turn on and off the compressor. Therefore, if the AC pressure switch is malfunctioning, the clutch won’t engage, preventing the compressor from pumping refrigerant throughout the AC system. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/3245f9ab-40ad-48d9-80b8-f0c39e13d8c5/Screen+Shot+2022-08-04+at+5.27.03+PM.png Symptoms - 4 SYMPTOMS OF A BAD AC PRESSURE SWITCH - engine light The first symptom you could be experiencing with your car is an engine light.

A good working compressor will cycle on and off to maintain the temperature it was set for. If the pressure switch in your car starts to go bad, you'll notice the AC switching on and off more frequently without reaching the desired temperature. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/0a0ac70b-901f-43e5-99ed-6cc5e6e880ee/AdobeStock_350693481.jpeg Symptoms - 4 SYMPTOMS OF A BAD AC PRESSURE SWITCH - AC blowing warm Since the compressor isn’t turning on due to a defective switch, it will result in the AC blowing warm air. There won’t be any refrigerant being pumped throughout the ac system, resulting in no cool air coming out from the vents. It’s important to note that your car can blow warm air due to low refrigerant levels, so it’s good to check on that, as well. Here is an excellent recharge kit. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/f3accb98-8439-42e4-ae78-fbf898109635/AdobeStock_332508741.jpg Symptoms - 4 SYMPTOMS OF A BAD AC PRESSURE SWITCH The purpose of the AC pressure switch is to act as a safety mechanism. If it notices the refrigerant pressure getting too high or too low it will shut off the compressor to avoid damaging it. The best way to locate the pressure switch is to follow the AC lines. The low-pressure switch will be on the larger line, while the high-pressure switch will be on the smaller line. The location can vary between cars. Here are some common locations of the AC pressure switch: By the AC condenser Receiver drier Mounted on the ac compressor On the firewall On the AC lines https://easyautofix.com/symptoms/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7-xhwbb-ya3ld-f6yj3-rl88n-9cg5d-4jfpn-8ee66-62cjl-ch7ld-ehdpk monthly 0.5 2023-09-05 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/8ccf75a3-661a-47be-a13e-d19ea91609e8/Screen+Shot+2022-10-19+at+4.55.50+PM.png Symptoms - 5 SYMPTOMS OF A CLOGGED FUEL INJECTOR - hard start/no start The second symptom of a clogged fuel injector is a hard start or a no start at all. A clogged-up fuel injector will either not let fuel pass through at all or restrict the exact amount needed. If the engine isn’t getting proper fuel per air ratio, it’s not going to be able to combust efficiently, leaving your vehicle with a hard start or a no start. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/99aa4eca-ccfa-44b8-bb44-b11108fcc9ea/Screen+Shot+2022-10-19+at+4.55.26+PM.png Symptoms - 5 SYMPTOMS OF A CLOGGED FUEL INJECTOR The purpose of the fuel injector is to open up for a specific amount of time to allow the proper amount of fuel to enter the engine to mix with air and spark to create combustion. A fuel injector could clog due to a bad fuel filter letting a small amount of debris pass through. Also, if you live in an area where it snows, salted streets are a huge contributor to corrosion. If your fuel lines start to get corroded over time, this will eat away the metal and can transfer to your fuel injectors. Another factor could be the type of fuel system you have. Most cars have multi-port fuel injection nowadays, but some newer cars have gasoline direct injection. This type of injection is known to cause carbon blockage on the fuel injectors since it’s right inside the combustion chamber, making it easier for the leftover fuel to heat up on it. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/826454e8-5869-48c9-809d-0a85ac67dc05/Screen+Shot+2022-10-19+at+4.56.09+PM.png Symptoms - 5 SYMPTOMS OF A CLOGGED FUEL INJECTOR - Stalling engine The fourth symptom of a clogged fuel injector is a stalling engine. You could be driving down the road when all of a sudden your car randomly turns off. This happens due to the lean mixture created by the clogged fuel injector. If you’re gassing the pedal to increase speed on the road, this is going to bring in more air. Then the ECM should be increasing more fuel. A clogged fuel injector won’t let the proper amount of fuel to be released in that split second, leaving your vehicle with a stalling engine. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/b1179d46-f9cb-4c6a-82cf-b4397dd647e3/Screen+Shot+2022-10-05+at+8.44.03+PM.png Symptoms - 5 SYMPTOMS OF A CLOGGED FUEL INJECTOR - rough idle The fifth symptom of a clogged fuel injector is a rough idle. You’ll feel your car shaking at the red light or a stop sign. This is due to the lack of fuel being released from the injector into the engine. Lack of fuel-to-air ratio leads to misfires, which creates inconsistency, causing vibrations in your car. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/3245f9ab-40ad-48d9-80b8-f0c39e13d8c5/Screen+Shot+2022-08-04+at+5.27.03+PM.png Symptoms - 5 SYMPTOMS OF A CLOGGED FUEL INJECTOR - engine light The first symptom your car could be experiencing is an engine light. Here are some codes that can pop up that are related to a bad fuel injector: P0201 P0202 P0203 P0204 P0205 P0206 P0207 P0208 P0209 If you have a clogged fuel injector, you should also have a code for a lean condition - P0171. A lean condition means you have more air than fuel in combustion. A lean condition can also lead to misfires, so you should also expect these codes: P0301 (Misfire Cylinder 1) P0302 (Misfire Cylinder 2) P0303 (Misfire Cylinder 3) P0304 (Misfire Cylinder 4) P0305 (Misfire Cylinder 5) P0306 (Misfire Cylinder 6) P0307 (Misfire Cylinder 7) P0308 (Misfire Cylinder 8) These codes can help you diagnose to see which fuel injector is clogged up.

If you press down on the gas pedal, the throttle plate will open up, bringing in more air. When there’s more air, the engine control module (ECM), should command more fuel. If the fuel injectors are clogged, they will not provide the proper amount of fuel at the rate at which the ECM is looking, leaving you with a delayed acceleration. https://easyautofix.com/symptoms/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7-xhwbb-ya3ld-f6yj3-rl88n-9cg5d-4jfpn-8ee66-62cjl-ch7ld-ehdpk-hb6xj monthly 0.5 2023-09-05 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/9a7c39d6-c92e-4dd3-9f46-b1afe75b659d/Screen+Shot+2022-09-12+at+4.04.15+PM.png Symptoms - 5 SYMPTOMS OF A BAD EGR VALVE - failed emissions The second symptom of a bad EGR valve is your vehicle failing the emissions test. This can be due to a stuck-closed EGR valve. A stuck-closed EGR valve will prevent exhaust gases from coming into the combustion process. If the exhaust gases don’t come in, the temperature inside the chamber will increase and produce more NOx. Too much NOx will lead to your car failing the emissions test. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/eacec73b-272e-4eff-b445-e75cca852ecf/IMG_1785.JPG Symptoms - 5 SYMPTOMS OF A BAD EGR VALVE - bad acceleration The fourth symptom of a bad EGR valve is acceleration issues. A stuck-open EGR valve can be the cause of this symptom. A stuck-open EGR will continuously add exhaust gases back into the combustion chamber. These gases will take up space, therefore, limiting the amount of air that enters for optimal engine performance. This is why your acceleration is lacking. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/b1179d46-f9cb-4c6a-82cf-b4397dd647e3/Screen+Shot+2022-10-05+at+8.44.03+PM.png Symptoms - 5 SYMPTOMS OF A BAD EGR VALVE - rough idle The fifth symptom of a stuck open EGR valve is a rough idle. The same reason occurs here. Since the EGR is stuck open, the exhaust gasses take up space inside the combustion process, not leaving much room for air to combust with fuel efficiency. This leads to improper combustion which results in your car having vibrations. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/1dabe7bc-dd25-49dd-b31f-a684a2f3f6ec/IMG_1367.JPG Symptoms - 5 SYMPTOMS OF A BAD EGR VALVE - engine light The first symptom of a bad EGR valve is an engine light.

This happens when an unplanned mini-detonation occurs during the power stroke in combustion. People describe it as a pinging noise. A stuck-closed EGR prevents exhaust gases from coming inside the combustion to cool it down for proper temperature levels. Hot temperature levels inside the combustion can ignite air and fuel at unwanted times which creates the engine knocking sound. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/3d74df35-02af-415a-83bb-9d6f52681610/Screen+Shot+2022-10-19+at+6.09.06+PM.png Symptoms - 5 SYMPTOMS OF A BAD EGR VALVE The purpose of the EGR valve (exhaust gas recirculation) is to open up and recirculate part of the exhaust gases back into the intake manifold. These exhaust gases help reduce the temperature of combustion. This is very important because NOx is formed in high temperatures, so reducing the temperature reduces the NOx formation. https://easyautofix.com/symptoms/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7-xhwbb-ya3ld-f6yj3-rl88n-9cg5d-4jfpn-8ee66-62cjl-ch7ld-ehdpk-hb6xj-2yy5c-ksw5k monthly 0.5 2023-09-05 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/04005303-d72c-46b2-a6b0-1e9a2cae5222/Screen+Shot+2022-10-24+at+2.39.56+PM.jpg Symptoms - 4 SYMPTOMS OF A BAD IDLE AIR CONTROL VALVE The purpose of the idle air control valve is to regulate the amount of air coming into the engine while stationary to ensure a smooth idle. Your car might not have an idle air control valve. Some newer cars have an electronic throttle body that’s controlled by the ECM (engine control module) to open up and allow airflow to ensure a smooth idle. An idle air control valve can go bad in 3 different ways: stuck-open, stuck-closed, or clogged. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/ea630f8b-ac26-41af-ae89-07ca6f06f809/Screen+Shot+2022-10-24+at+2.58.44+PM.png Symptoms - 4 SYMPTOMS OF A BAD IDLE AIR CONTROL VALVE - IDLE TOO HIGH/TOO LOW The second symptom you might be experiencing with your car is noticing your idle is too high or too low. If the idle air control valve is stuck open, it will increase the air going into the engine, which will increase your RPM, usually above 1000. If the idle air control valve is stuck closed or clogged, it will restrict air from coming into the engine, which will cause your RPM to drop below 600. An average idle RPM range should be between 600 and 1000. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/d4563709-5b7b-45ce-a244-c8187e6d27b6/Screen+Shot+2022-10-24+at+2.58.56+PM.jpg Symptoms - 4 SYMPTOMS OF A BAD IDLE AIR CONTROL VALVE - engine stall during idle The third symptom of a faulty idle air control valve is the engine stalling during idle. If the idle air control valve is closed or clogged to the point where not enough air is coming into the engine to keep it running, it will result in an engine stall. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/66c34c2e-e99a-451b-b9f9-202e4852a6c3/IMG_0645.jpg Symptoms - 4 SYMPTOMS OF A BAD IDLE AIR CONTROL VALVE - engine light The first symptom of a bad idle air control valve is having an engine light on.

The sensor could be sending a faulty reading of a colder engine than what it actually is. When the PCM reads a colder engine, it wants to add more fuel. This happens because the PCM always wants to have the perfect air-fuel ratio, which is14.7 air to 1 gasoline. When the engine is cold, the air is more dense, so there’s more of it. When there’s more air, there should be more fuel. This is why a faulty reading from the sensor can make the engine use more fuel than it should, resulting in poor gas mileage. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/77bf9d97-0636-4659-9fa7-1f4297d6eb57/IMG_2533.jpg Symptoms - 5 SYMPTOMS OF A BAD COOLANT TEMPERATURE SENSOR The purpose of the coolant temp sensor is to read the temperature of the coolant that circulates through the engine. When the temperature changes, resistance changes. This is how the PCM (powertrain control module) calculates the temperature of the coolant. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/3d7bce7c-456c-432a-a56c-167288c8d590/Screen+Shot+2022-10-24+at+2.15.03+PM.png Symptoms - 5 SYMPTOMS OF A BAD COOLANT TEMPERATURE SENSOR - Reduced power The fifth symptom of a bad coolant temperature sensor is reduced engine power. The sensor is a contributor to running the perfect air-fuel ratio for combustion, and if it’s faulty it’s going to throw these numbers off. This Causes an inefficient burn, which leads to lower engine performance. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/251ee54e-de03-400c-9906-3a91a3310c66/Screen+Shot+2022-10-24+at+2.14.44+PM.png Symptoms - 5 SYMPTOMS OF A BAD COOLANT TEMPERATURE SENSOR - overheating The second symptom you might be experiencing with your car is an overheating engine. This can be due to the cooling fans not turning on. The PCM commands the radiator fans to turn on as soon as the engine reaches 200°F. If the sensor is faulty and tells the PCM it’s reading 120°F, it’s never going to be able to turn on the fans, resulting in your engine overheating. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/7aae5228-c758-4d51-aef0-f298e4b9d7fb/Screen+Shot+2022-10-24+at+2.14.58+PM.png Symptoms - 5 SYMPTOMS OF A BAD COOLANT TEMPERATURE SENSOR - black smoke The fourth symptom you could be experiencing is black smoke coming out of the tailpipe.

In some situations, there can be so much carbon buildup around the throttle plate that it can cause it to stick. A sticky throttle plate can be the reason why your car has acceleration issues. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/cf1a29e4-2216-4c4e-9fc3-47b1163ec222/Screen+Shot+2022-10-12+at+5.42.06+PM.png Symptoms - SYMPTOMS OF A DIRTY THROTTLE - poor mpg The third symptom of a dirty throttle is poor gas mileage. When the ECM commands the throttle plate to open up more during idle, there should be more air coming in, which results in the ECM commanding more fuel. If you have a drive-by cable throttle body your gas mileage could suffer due to the carbon build-up, leading to an incorrect air-fuel ratio, causing an inefficient burn. This is the reason why you’re going to the gas station more often. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/6e67fc05-10f8-43bc-9900-9ec7b75c8ce9/Screen+Shot+2022-10-14+at+9.47.02+PM.png Symptoms - SYMPTOMS OF A DIRTY THROTTLE - Rough idle The second symptom of a dirty throttle body is a rough idle. When your car is idling, the throttle is open just a tad bit to let air inside the engine for combustion. If there’s carbon buildup around the edges of the throttle plate, the air-fuel ratio starts to suffer due to restrictions of the airflow, which results in vibrations. If you have a drive-by-wire throttle body (electronic throttle body), in some situations the ECM will open up the throttle plate gap to compensate for the lack of airflow. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/a60b3daf-650a-4b0d-92ce-e9707c256dbf/Screen+Shot+2022-10-14+at+9.46.49+PM.png Symptoms - SYMPTOMS OF A DIRTY THROTTLE The purpose of the throttle body is to control the amount of air coming into the engine. As you press down on the gas pedal, the throttle plate opens up allowing more air into the engine. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/3245f9ab-40ad-48d9-80b8-f0c39e13d8c5/Screen+Shot+2022-08-04+at+5.27.03+PM.png Symptoms - SYMPTOMS OF A DIRTY THROTTLE - engine light The first symptom you might be experiencing with a dirty throttle body is having a check engine light on. An engine code known for this cause is P0121.

If you hear rattling, whirring, or humming noises coming from your vehicle, it could be due to a defective torque converter. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/d398ab88-ffe7-4f0b-9240-d85c164cb27a/Screen+Shot+2022-10-12+at+9.33.06+PM.png Symptoms - SYMPTOMS OF A BAD TORQUE CONVERTER - SHUDDERING The second symptom is shuddering. To give you a better idea, your car will shake as if you're driving on a bumpy road. This usually happens at around 30-45 mph, although it can vary from car to car. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/a77927d1-c5f9-4640-8920-473580cdaf7f/Screen+Shot+2022-10-14+at+9.46.10+PM.png Symptoms - SYMPTOMS OF A BAD TORQUE CONVERTER The purpose of the torque converter is to prevent the car from stalling when coming to a stop, multiply torque, and drive the front pump of the automatic transmission. If you have a manual car you won’t have one, you'll have a mechanical clutch. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/3245f9ab-40ad-48d9-80b8-f0c39e13d8c5/Screen+Shot+2022-08-04+at+5.27.03+PM.png Symptoms - SYMPTOMS OF A BAD TORQUE CONVERTER - engine light The first symptom of a bad torque converter is having your check engine light on. If the torque converter clutch is bad, these codes may show up: P0740 P0741 P0742 P0743. Ensure you can access your car's diagnostic codes by acquiring an OBD2 scanner here.

This means your engine is overheating. A stuck-closed thermostat can be the cause of this. Since the thermostat never opens, it will never be able to go through the radiator, which cools down the coolant that goes back to the engine. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/fa742920-0bed-48c1-91af-323255b07308/Screen+Shot+2022-10-12+at+12.30.48+PM.jpg Symptoms - SYMPTOMS OF A BAD THERMOSTAT - lack of heat The third symptom of a stuck open thermostat could be poor heating performance in the interior of the car. Since a stuck open thermostat will have coolant always flowing through the radiator to get cooled, it’s going to affect the heat in your car. A good thermostat will close at proper times allowing the coolant to heat up faster improving the quality of heat in the interior. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/3abdb02b-a9ea-4bef-a4af-b90e3ef7caac/IMG_2295.jpg Symptoms - SYMPTOMS OF A BAD THERMOSTAT The purpose of the thermostat is to help the engine run at operating temperature. When the engine gets very hot, the thermostat opens up to let coolant flow through the radiator to cool it down and recirculate back to the engine. This prevents the engine from overheating. On the flip side, when the engine is cold, the thermostat is closed to help the engine warm up faster. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/eec571a2-3eb1-441a-bd65-91f91dea91eb/IMG_1996+2.jpg Symptoms - SYMPTOMS OF A BAD THERMOSTAT - ENGINE LIGHT The first symptom you might be experiencing with a stuck open thermostat is having an engine light on. A code known for this cause is P0128. This code means the coolant is taking longer than usual to reach operating temperature. Ensure you can access your car's diagnostic codes by acquiring an OBD2 scanner here. The thermostat can still be bad with the engine light off, so let’s move on to the next symptom. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/511aafc8-216d-458e-bf9e-ef215bbcea16/Screen+Shot+2022-10-12+at+12.47.27+PM.jpg Symptoms - SYMPTOMS OF A BAD THERMOSTAT - leaking coolant The fifth symptom of a closed thermostat is leaking coolant. The coolant could be leaking from the thermostat housing or it could leak from one of the hoses. This happens because as temperature rises, pressure rises, causing items to expand until they pop. In this case, results in a leak. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/c1208fb7-4c71-400c-88fc-60e2627c2062/Screen+Shot+2022-10-12+at+11.54.19+AM.jpg Symptoms - SYMPTOMS OF A BAD THERMOSTAT - warm up delay The second symptom of a stuck open thermostat could be the temperature gauge taking longer than usual to reach the halfway mark. A stuck-open thermostat allows coolant to travel from the engine through the radiator which cools down the coolant and goes back into the engine. Since the coolant process repeats over and over, it delays the time for the engine to reach the operation temperature. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/cb07bbdf-5561-454b-9524-e670430e4ef6/Screen+Shot+2022-10-12+at+11.50.01+AM.jpg Symptoms - SYMPTOMS OF A BAD THERMOSTAT - The thermostat can be found by following the lower radiator hose that goes straight to the engine. Although in some cars it could be found following the upper hose. https://easyautofix.com/symptoms/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7-xhwbb-ya3ld-f6yj3-rl88n-9cg5d-4jfpn-8ee66-62cjl monthly 0.5 2023-09-05 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/c948e297-a598-4fb9-8b13-ae63286c6c6a/Screen+Shot+2022-10-05+at+8.44.20+PM.png Symptoms - SYMPTOMS OF A BAD IGNITION COIL - smell of gas The fourth symptom of a bad ignition coil is the smell of gas. If the ignition coil is slowly wearing out, it won’t send the full amount of volts needed for the spark plug to produce a great spark. This leaves the cylinder with unburnt fuel and air to travel out of the exhaust, resulting in the smell of gas. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/19da3175-740a-4ea9-b9b0-3e1950c5b0ec/Screen+Shot+2022-10-05+at+8.43.55+PM.png Symptoms - SYMPTOMS OF A BAD IGNITION COIL - The location of the ignition coil depends on the engine and the type of ignition system in your car. In this article, we’ll be talking about the coil-on-plug ignition system. In this system, each spark plug has its own ignition coil. Spark plugs can be on top of the engine, divided between the left/right side, or divided between the front/back side of the engine. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/74a302b4-1134-474d-b6bb-166506933216/IMG_1234.jpg Symptoms - SYMPTOMS OF A BAD IGNITION COIL The purpose of the ignition coil is to convert 12 volts from the battery up to 40,000 volts. This voltage goes into the spark plug to produce a spark. Then, the spark ignites with air and fuel to start combustion. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/3245f9ab-40ad-48d9-80b8-f0c39e13d8c5/Screen+Shot+2022-08-04+at+5.27.03+PM.png Symptoms - SYMPTOMS OF A BAD IGNITION COIL - engine light The first symptom of a bad ignition coil is having an engine light on. Here are some codes that can pop up: P0300 - P0312 (misfire) In some cars, these codes can also show up: P0350 - P0362 (ignition coil fault) Ensure you can access your car's diagnostic codes by acquiring an OBD2 scanner here. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/6577b241-b780-432d-b615-039897c90094/Screen+Shot+2022-10-05+at+8.44.03+PM.png Symptoms - SYMPTOMS OF A BAD IGNITION COIL - Rough idle The second symptom of a faulty ignition coil is a rough idle. The ignition coil is responsible to send voltage through the spark plug for it to spark, so if it fails there won’t be a spark, leaving your car with a misfire. For example, if your vehicle has a four-cylinder engine and one cylinder has a misfire, your engine will become less efficient by a quarter, which explains the rough idle. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/03c147c7-22c2-4a83-a7be-686c637f9733/Screen+Shot+2022-10-05+at+8.44.11+PM.png Symptoms - SYMPTOMS OF A BAD IGNITION COIL - loss of power The third symptom you might be experiencing is a loss of power. Due to misfires occurring in the engine, your car won’t be able to accelerate as fast. https://easyautofix.com/symptoms/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7-xhwbb-ya3ld-f6yj3-rl88n-9cg5d-4jfpn-8ee66-kh85m monthly 0.5 2022-11-21 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/5d673bd9-25f6-4619-9fee-126a1901b1a2/Screen+Shot+2022-10-01+at+1.02.58+PM.png Symptoms - SYMPTOMS OF A BAD ALTERNATOR - engine stalling The fourth symptom of a faulty alternator is your engine stalling. You’ll be driving to the store, and your car will randomly turn off in the middle of the road, leaving you wondering what happened. For your car to run, it needs air, spark, and fuel. Fuel and spark are controlled through electricity, which comes from the alternator that charges your battery. If the alternator is not working properly, nothing in your car will work. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/65c1cccc-0a5e-447c-8757-cda35c4c8e34/Screen+Shot+2022-10-01+at+1.02.50+PM.png Symptoms - SYMPTOMS OF A BAD ALTERNATOR - warning light The first symptom of a bad alternator is a warning light. Different cars have different warning lights. Your car may have a battery light, an ALT light, or a GEN light. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/f1c66ba0-196e-49f8-b1dc-d27055365ba8/Screen+Shot+2022-10-01+at+12.57.20+PM.png Symptoms - SYMPTOMS OF A BAD ALTERNATOR - ACCEssory failure The fifth symptom of a bad alternator is an accessory failure. Your car’s radio could be turning on and off, or sometimes not even working at all. Your power windows could also be super slow, or your power locks could start to act up. A good rule of thumb to know if you have a bad alternator is when multiple accessories are going out at once, and not just one. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/caea9659-f746-4920-8dee-f4e7b614af52/Screen+Shot+2022-10-01+at+12.57.06+PM.png Symptoms - SYMPTOMS OF A BAD ALTERNATOR - odd noises The second symptom you could be experiencing is hearing weird noises. If you hear a grinding noise, it could be the bearings going out of the alternator. If you hear a squealing noise, maybe it’s time to look into your serpentine belt. A bad serpentine belt can be the reason why your alternator is not working properly. A worn belt can have less traction to rotate the alternator causing the same symptoms as a bad alternator. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/0daae82e-07f7-4624-854d-890120b8e588/Screen+Shot+2022-10-01+at+12.56.57+PM.png Symptoms - SYMPTOMS OF A BAD ALTERNATOR - The location of the alternator will vary from car to car. Some cars have the alternator towards the front of the engine, while others have it towards the left of the engine. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/b71f2c13-642c-4229-9656-92dfbd1b23aa/Screen+Shot+2022-10-01+at+12.57.12+PM.png Symptoms - SYMPTOMS OF A BAD ALTERNATOR - headlight problems The third symptom of a bad alternator is having headlight problems. When you’re driving at night, you’ll notice that your headlights are dim. Also, when you’re driving down the road and see the headlights flickering (turning off and on fast), it’s a good indicator that your alternator is faulty. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/ddd496ed-c0c1-4c6e-9f15-f19505331252/Screen+Shot+2022-10-01+at+12.57.27+PM.png Symptoms - SYMPTOMS OF A BAD ALTERNATOR - dead battery The sixth symptom you could be experiencing is a dead battery. If whenever you turn on your car you hear a rapid clicking noise, and the only way to get your car to start is through jumper cables, you might be thinking that you just need to replace the battery. However, whenever you replace the battery, you find out that it’s dead again the next day. Now you can have the best battery for your car, but if your alternator is not doing its job, then your battery is always going to be dead. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/781db404-264a-4192-b0cf-d72af7be3ed8/Screen+Shot+2022-10-01+at+12.56.46+PM.png Symptoms - SYMPTOMS OF A BAD ALTERNATOR The purpose of the alternator is to charge the battery and run electrical components in your car.

The reason why is because of the incorrect data leading to improper spark and fuel commands from the ECM, resulting in misfires and poor combustion efficiency. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/96ec47d9-6c92-4c56-a5d9-fe2bb5a5df60/Screen+Shot+2022-09-30+at+5.39.09+PM.jpg Symptoms - SYMPTOMS OF A BAD CAMSHAFT POSITION SENSOR - delayed start/no start The second symptom of a malfunctioned camshaft position sensor is a delayed start. You go to start your car and it’s taking a lit bit longer than it usually does. Since the ECM isn’t getting the correct data from the camshaft to command spark at the perfect time. It’s going to delay the car to start or not even start at all. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/37f45e87-0b36-498b-b935-a47c687d944a/AdobeStock_506804376.jpeg Symptoms - SYMPTOMS OF A BAD CAMSHAFT POSITION SENSOR - To paint a better picture in your head, the internal combustion engine starts with the camshaft opening the intake valve, allowing air and fuel commanded by the ECM to the combustion chamber. All valves then close for the piston to compress the air-fuel mixture. Once the piston reaches the top, the ECM commands spark for combustion to occur pushing that piston down, creating power. Finally, the camshaft opens the exhaust valves and the pistons come back up to let the gases out of the exhaust manifold. With all of this in sync, this is how combustion occurs. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/0d121982-c03c-4e71-bad2-057c558a8dc0/Screen+Shot+2022-09-12+at+9.59.22+PM.jpg Symptoms - SYMPTOMS OF A BAD CAMSHAFT POSITION SENSOR - engine light The first symptom of a bad camshaft position sensor is an engine light. If the engine control module senses something wrong with the camshaft sensor, the engine light will pop up.

Since the engine control module is responsible for commanding fuel when the camshaft opens the intake valve, allowing it into the combustion chamber, if the reading is faulty the ECM will never know when to command fuel at the perfect time, resulting in poor gas mileage. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/08d4dc21-b51c-429c-9d6d-67a57afede96/IMG_3286.jpg Symptoms - SYMPTOMS OF A BAD CAMSHAFT POSITION SENSOR The purpose of the camshaft position sensor is to measure the rotations and position of the camshaft. The ECM uses this data to know when to command spark and fuel for the best engine efficiency. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/cc37d66d-3afb-4857-aeb9-34319e8d5d30/Screen+Shot+2022-09-30+at+5.39.29+PM.jpg Symptoms - SYMPTOMS OF A BAD CAMSHAFT POSITION SENSOR - rough idle The fourth symptom of a faulty camshaft position sensor is a rough idle. Since the ECM is getting faulty camshaft data from the sensor it’s not going to command spark during the power stroke when the camshaft has both intake and exhaust valves closed, preventing proper combustion to occur. If a spark doesn’t occur at this time, it will lead to a misfire resulting in your car having vibrations or in other words a rough idle. https://easyautofix.com/symptoms/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7-xhwbb-ya3ld-f6yj3-rl88n-9cg5d-4jfpn monthly 0.5 2023-09-05 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/b7153b78-72c2-4487-b36d-da078b726efc/Screen+Shot+2022-09-22+at+5.01.04+PM.jpg Symptoms - SYMPTOMS OF A BAD MAP SENSOR - engine stalling The second symptom of a faulty MAP sensor is your engine stalling. Imagine, you turn on your car, start listening to some music, and a minute later your car suddenly turns off. For example, if the MAP sensor tells the ECM it reads less air coming in, then the ECM is going to produce less fuel. But a good working MAP sensor should be reading more air coming in. So there should be more fuel being added. This leads to more air than fuel ratio, which results in no combustion. That’s why you’re experiencing your engine stalling. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/094ebd1a-e654-4e07-ab42-5fb90dc26e42/Screen+Shot+2022-09-12+at+3.03.01+PM.jpg Symptoms - SYMPTOMS OF A BAD MAP SENSOR - bad fuel ecnomy The seventh symptom of a bad MAP sensor could be a bad fuel economy. If the MAP sensor provides a bad reading of more air, the ECM is then going to want to provide more fuel. But the real reading should have been less air, so the ECM should have been providing less fuel. The final result came out to be less air and more fuel, leaving unburnt fuel in the cylinder. This is why you have to go to the gas station more often. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/c06e2f23-0098-467c-8e4b-cee7699a7d00/IMG_1981.jpg Symptoms - SYMPTOMS OF A BAD MAP SENSOR The purpose of the MAP sensor is to provide manifold pressure to the ECM. The engine control module then uses this information to produce the perfect air-fuel ratio of 14.7 (air) to 1 (gasoline). With that being said, if the ECM reads more air coming in, it’s going to command more fuel. If it reads less air coming in, it’s going to command less fuel. The MAP sensor's location will be on the intake manifold, typically right after the throttle. Note: you might not have a MAP sensor. Your vehicle might be equipped with a MAF sensor.

Here are some codes related to a bad MAP sensor: P0105 P0106 P0107 P0108 P0109 Ensure you can access your car's diagnostic codes by acquiring an OBD2 scanner here. It’s important to remember that you can still have a faulty MAP sensor with no check engine light on, so let’s move on to the next symptom. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/b2409f7d-2412-4111-b13c-6915620c0593/Screen+Shot+2022-09-22+at+5.01.12+PM.png Symptoms - SYMPTOMS OF A BAD MAP SENSOR - misfire The third symptom you can be experiencing is a misfire. The same reason would apply here as in the previous symptom. More air than fuel ratio would lead to no combustion, which is going to create an engine misfire. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/289d25fb-2374-4218-8589-c52b741ec77c/Screen+Shot+2022-09-22+at+5.01.21+PM.jpg Symptoms - SYMPTOMS OF A BAD MAP SENSOR - Rough idle The sixth symptom you can be experiencing is a rough idle. Let’s say, the air-fuel ratio is not too bad to the point where it’s going to create a no-start. But it’s still bad enough to create a rough idle and a couple of misfires here and there. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/42183adb-b03d-42b0-b243-f99d6d09999c/IMG_1019.JPG Symptoms - SYMPTOMS OF A BAD MAP SENSOR - no start The fifth symptom of a bad MAP sensor could be a no-start. If the reading is bad and there’s more air and less fuel coming in, it’s going to prevent the combustion from occurring. That’s why you may be experiencing a no-start. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/3c056066-2ef1-44aa-8d7f-d2991da99150/Screen+Shot+2022-09-12+at+3.03.05+PM.jpg Symptoms - SYMPTOMS OF A BAD MAP SENSOR - black smoke The last symptom of a faulty MAP sensor is black smoke coming out of the exhaust pipe. Since there’s unburnt fuel in the cylinder, it gets kicked out to the exhaust where it gets burned and creates black smoke. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/97f9a1c4-970b-484b-9e05-40b10045920c/IMG_1379.JPG Symptoms - SYMPTOMS OF A BAD MAP SENSOR - reduced power The fourth symptom of a bad MAP sensor is reduced engine power. You’re driving down the road and trying to accelerate, but the power isn’t there. This all comes back to the fuel not being burned efficiently. In order for the engine to run as smoothly as possible, the air-fuel ratio has to be the best that it can be. https://easyautofix.com/symptoms/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7-xhwbb-ya3ld-f6yj3-rl88n-9cg5d monthly 0.5 2023-09-05 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/253e1537-84b6-496d-bb1d-670a7a598578/Screen+Shot+2022-09-12+at+4.04.15+PM.jpg Symptoms - SYMPTOMS OF A BAD EVAP CANISTER - failed emissions The third symptom is a failed emissions test. If you have a leak or a clog in the EVAP system, the fuel tank pressure sensor will read the pressure difference and the ECM will illuminate the check engine light. Having the light on will automatically fail your emissions test. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/48b024a6-5558-40db-95b9-7f70d386d00d/Screen+Shot+2022-09-12+at+4.03.23+PM.png Symptoms - SYMPTOMS OF A BAD EVAP CANISTER The location of the charcoal canister will usually be underneath the vehicle near the fuel tank. In some situations, it can also be in the engine compartment under the master cylinder or in front of the coolant reservoir. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/4a3e4734-80f5-40a4-a671-d1574bcfcdc6/Screen+Shot+2022-09-12+at+4.03.01+PM.jpg Symptoms - SYMPTOMS OF A BAD EVAP CANISTER The purpose of the charcoal canister is to store gasoline vapors that are created in the fuel tank. These fuel vapors will end up being transferred to the engine, where they get burned depending on when the ECM commands the purge valve to open. This reduces emissions and increases MPG. If you have a diesel engine you won't have a charcoal canister, since the diesel fuel is not as volatile as gasoline. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/2cf95f09-8f23-4b3d-a140-bc73243f7bc4/IMG_0645.jpg Symptoms - SYMPTOMS OF A BAD EVAP CANISTER - engine light The first symptom of a bad charcoal canister is having a check engine light on. Now there's not a direct code that detects a bad charcoal canister but there are some codes that can lead you in the right direction. Here are some codes that can pop up if your canister is cracked or clogged: P0440 P0441 P0442 P0446 P0455 P0496 Ensure you can access your car's diagnostic codes by acquiring an OBD2 scanner here. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/78f8065f-3799-49e1-9ea2-e1b0acef730d/IMG_2008+2.jpg Symptoms - SYMPTOMS OF A BAD EVAP CANISTER - gas pump keeps shutting off The second symptom is the gas pump keeps shutting off while fueling. You're putting gas in your car and with just one or two dollars it clicks and turns off as if it was a full tank. This can happen if the canister is clogged increasing the fuel vapor pressure which is why your pump keeps turning off. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/a3b42815-a062-4a37-b406-e0427ee18c76/Screen+Shot+2022-09-05+at+6.20.53+PM.jpg Symptoms - SYMPTOMS OF A BAD EVAP CANISTER - fuel smell The fourth symptom is noticing a fuel smell. You could experience this if the charcoal canister is cracked or damaged. If it is, the trapped gasoline vapors will escape to the outside, which is why you're noticing a fuel smell. https://easyautofix.com/symptoms/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7-xhwbb-ya3ld-f6yj3-rl88n monthly 0.5 2023-09-05 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/36904b28-4ed4-4a21-9f40-27d69575e462/Screen+Shot+2022-08-04+at+5.27.14+PM.jpg Symptoms - SYMPTOMS OF A BAD MASS AIRFLOW SENSOR - rough idle The third symptom you might be experiencing with your car is a rough idle. Let's say your car starts at odd times and you drive it only to figure out that you feel your car shaking when it's at a stop sign or a red light. The reason for this could be the same factor the ECM is getting a faulty reading of less air coming in, therefore, it commands less fuel. However, a good working MAF sensor should have been reading more air, so it should have been adding more fuel. This results in more air than fuel, which leads to poor combustion efficiency with a couple of misfires. This is why you’re experiencing a rough idle. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/55570705-8ce7-4368-97d2-82006ff3bc5d/Screen+Shot+2022-09-12+at+2.46.34+PM.jpg Symptoms - SYMPTOMS OF A BAD MASS AIRFLOW SENSOR - no start The second symptom of a bad MAF sensor is a no-start. If the MAF sensor is giving the wrong reading of less air coming in, then the ECM will command less fuel. But in reality, there's more air coming in, so the ECM should have been commanding more fuel. This results in more air than fuel ratio, which causes poor combustion and gives us a no start. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/930e7903-5a62-409a-b4bf-b87716930e2a/IMG_1367.jpg Symptoms - SYMPTOMS OF A BAD MASS AIRFLOW SENSOR - engine light The easiest way to figure out if your MAF sensor is bad is by noticing if the check engine light is on. Here are some codes related to a bad mass airflow sensor: P0100 P0101 P0102 P0103 P0104 Ensure you can access your car's diagnostic codes by acquiring an OBD2 scanner here. There are times when the engine light doesn't come on but the sensor is still faulty, so let's move on to the next symptom of a bad MAF sensor. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/c61d08db-ddac-4b06-ad9c-c56a9537648b/Screen+Shot+2022-09-07+at+1.44.19+PM.jpg Symptoms - SYMPTOMS OF A BAD MASS AIRFLOW SENSOR The MAF sensor will typically be located on the air intake before the throttle. Not all cars have a mass airflow sensor, yours might come with a MAP sensor, instead. If your vehicle has a MAP sensor, then you need to check out my video on the Symptoms of a bad MAP sensor. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/eabb0d2b-cea4-40be-ad89-676f93fb5cda/Screen+Shot+2022-09-12+at+3.03.01+PM.jpg Symptoms - SYMPTOMS OF A BAD MASS AIRFLOW SENSOR - bad fuel economy The fourth symptom you might be experiencing with your car is bad fuel economy. Now let's flip the script here and say the MAF sensor is giving the ECM a faulty reading of more air coming in. This will result in the ECM commanding more fuel. However, the real reading should have been less air coming in, so the ECM should have been commanding less fuel. Since the ECM got tricked by a faulty MAF sensor, as a result, there will be more fuel than air ratio, which means the ECM is using more fuel than what is needed this can be the reason why your fuel economy has been suffering. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/5da0c9ba-e44e-4ffc-8d4e-3d8e2c9c8ac4/IMG_3797.jpg Symptoms - SYMPTOMS OF A BAD MASS AIRFLOW SENSOR The purpose of the Mass Airflow Sensor (also known as a MAF sensor) is to read the amount of air coming into the engine. The ECM then uses this data to calculate the best air-fuel ratio for the combustion. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/dbc6317c-5972-4b15-a751-27cd4e99577b/Screen+Shot+2022-09-12+at+3.03.05+PM.jpg Symptoms - SYMPTOMS OF A BAD MASS AIRFLOW SENSOR - black smoke The last symptom is black smoke coming from the exhaust. Due to the previous example of more fuel being used than what is needed the leftover fuel gets kicked out of the exhaust, which gets burned and turns into black smoke. https://easyautofix.com/symptoms/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7-xhwbb-ya3ld-f6yj3-rl88n-9cg5d-g7eys monthly 0.5 2023-09-05 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/a56562fa-c17a-453c-ad20-6e0eb3c3f78a/Screen+Shot+2022-09-12+at+9.59.30+PM.jpg Symptoms - SYMPTOMS OF A BAD ECM (ENGINE CONTROL MODULE) - engine stalling The third symptom of a faulty ECM is your engine stalling. You’re driving down the road and your car just gives out and turns off for no reason. The same reason applies here. The engine control module is not giving the proper spark and fuel commands at the perfect time to execute an efficiently running engine. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/06a266f1-e0fa-426a-9aeb-b21110ced36a/Screen+Shot+2022-09-13+at+4.17.33+PM.png Symptoms - SYMPTOMS OF A BAD ECM (ENGINE CONTROL MODULE) - shifting problems The fifth symptom of a bad ECM is shifting problems. Your car could be making a hard shift when changing gears or maybe you’ll experience a delayed shift. The reason why this could happen is because the ECM communicates the throttle position data to the transmission control module to shift efficiently. If the ECM is sending a faulty reading to the TCM, shifting problems start to occur. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/322efa52-5c15-4053-8a33-64e69b84546b/Screen+Shot+2022-09-12+at+9.48.42+PM.jpg Symptoms - SYMPTOMS OF A BAD ECM (ENGINE CONTROL MODULE) The purpose of the ECM is to monitor most sensors in your car to calculate ignition timing, air-fuel ratio, and emissions. Some people relate this to the brain of the car. The engine control module also warns you with an engine light if it senses something wrong and gives you a code for diagnostic purposes. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/989f41ed-e4d3-436b-ba10-3a413d6a8974/Screen+Shot+2022-09-12+at+9.59.22+PM.jpg Symptoms - SYMPTOMS OF A BAD ECM (ENGINE CONTROL MODULE) - engine light The first symptom of a bad engine control module is having a check engine light on. If the ECM is malfunctioning, it’s going to throw off a code. Here are some codes related to the ECM: P0600 P0601 P0602 P0603 P0604 P0605 Ensure you can access your car's diagnostic codes by acquiring an OBD2 scanner here. In some situations, the ECM might be throwing engine sensor codes that don’t even have a problem. You change the brand new sensor, you check the wiring for tears, you check the connections for corrosion, and everything checks to be good but unfortunately, the engine light is still on. This could be due to the internal damage of the ECM. Maybe water got inside and started to cause corrosion or there could have been a shortened side on that specific circuit. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/b060efa2-e338-47aa-899b-fc3c3054f40f/IMG_1020.jpg Symptoms - SYMPTOMS OF A BAD ECM (ENGINE CONTROL MODULE) - no start The second symptom of a bad ECM is a no-start. The engine control module monitors important engine sensors in your car, like the crankshaft sensor, mass airflow sensor, and oxygen sensors to make fuel injections and spark decisions. If it’s failing it won’t be able to make the proper commands. All of these factors are super important for your car to start. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/68357aa8-2364-4778-b68b-667b01c8e306/Screen+Shot+2022-09-12+at+9.59.35+PM.jpg Symptoms - SYMPTOMS OF A BAD ECM (ENGINE CONTROL MODULE) - acceleration loss The fourth symptom you might be experiencing with your car is a loss of acceleration. The ECM is also responsible for reading the throttle position. If the reading is faulty, it won’t make the right commands, creating an improper air-fuel ratio. https://easyautofix.com/symptoms/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7-xhwbb-ya3ld-f6yj3 monthly 0.5 2023-09-05 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/2084bdd4-277b-451b-884a-7e67ad73e5cc/Screen+Shot+2022-09-05+at+6.21.02+PM.png Symptoms - SYMPTOMS OF A BAD CATALYTIC CONVERTER - failed emissions The third symptom of a bad catalytic converter is failing the emissions test. If the catalytic converter is faulty, it will never be able to convert harmful emissions to safer gases for the environment, resulting in your car failing the emissions test. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/2cd40316-e0ff-4c2e-b71b-ea73ccfaa2a2/Screen+Shot+2022-09-05+at+6.20.38+PM.png Symptoms - SYMPTOMS OF A BAD CATALYTIC CONVERTER The catalytic converter will be located on the exhaust system (pointed with a red arrow). https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/75dca2c5-0093-43d8-a443-779458cb13b7/Screen+Shot+2022-09-05+at+6.20.28+PM.png Symptoms - SYMPTOMS OF A BAD CATALYTIC CONVERTER The purpose of the catalytic converter is to convert harmful emissions coming from combustion into safer gases for the environment. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/0f8ed71e-e86c-4ed3-aa35-025de5fa9612/Screen+Shot+2022-09-05+at+6.20.53+PM.png Symptoms - SYMPTOMS OF A BAD CATALYTIC CONVERTER - Egg smell The second symptom of a faulty catalytic converter is your vehicle smelling like rotten eggs while you’re driving. If the honeycomb inside the catalytic converter is either broken or clogged, it won’t be able to convert the smelly gas called hydrogen sulfide into an odorless gas resulting in a rotten egg smell. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/17d4b67a-1288-4d87-9473-4bfd05d9b56d/Screen+Shot+2022-09-05+at+6.21.10+PM.png Symptoms - SYMPTOMS OF A BAD CATALYTIC CONVERTER - poor performance The fourth symptom you might be experiencing is poor engine performance. Imagine, you’re at the red light, looking at your opponent, and when the light turns green, you floor it only to find out that you’re limited to 3000 RPM. This can happen if your catalytic converter is dirty or clogged. The reason why your car would lose performance is because of its inability to breathe out the exhaust gases. Since the exhaust gases can’t escape out efficiently through the catalytic converter, they will have nowhere to go but to stay in a combustion chamber. These gases will take up space instead of air, messing up the air-fuel ratio, which prevents perfect combustion. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/935d0f2c-0f21-4e42-a141-1558dbe87f09/Screen+Shot+2022-09-05+at+6.21.17+PM.png Symptoms - SYMPTOMS OF A BAD CATALYTIC CONVERTER - rattling noise The fifth symptom of a bad catalytic converter is a rattling noise coming from the catalytic converter. The rattling noise could be made by a broken-down honeycomb. This could be caused by a rich condition, meaning the air-fuel ratio was not correct, having more fuel than what was actually needed. This extra fuel gets kicked into the catalytic converter, increasing the temperature to the point where it breaks the honeycomb. This is why it’s super important to fix the problem right away to prevent the honeycomb from shattering. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/ee65bf21-bb38-49be-8436-5dafe334669e/Screen+Shot+2022-09-05+at+6.20.46+PM.png Symptoms - SYMPTOMS OF A BAD CATALYTIC CONVERTER - engine light The first symptom of a bad catalytic converter is having an engine light on.

It’s also important to note that you can still have a faulty oxygen sensor without an engine light, so let’s move on to the next symptom. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/82080b46-4058-4546-a360-e4a8f0260521/Screen+Shot+2022-08-30+at+1.57.33+PM.png Symptoms - SYMPTOMS OF A BAD OXYGEN SENSOR - poor performance The second symptom you might be experiencing with your car is poor engine performance. The better your car can come to a perfect burn, the better performance it will have. If you have a faulty O2 sensor, it could be sending a false rich or lean condition to the ECM. The ECM will then try to fix the problem that doesn’t exist by adding more or less fuel, messing up the air-fuel ratio. This can be the reason why your car has been sluggish lately. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/45b12ae8-e2b6-45be-81ed-b94ecfef3ee5/Screen+Shot+2022-08-30+at+1.57.47+PM.png Symptoms - SYMPTOMS OF A BAD OXYGEN SENSOR - rough idle The third symptom of a malfunctioned oxygen sensor is a rough idle. Since the ECM is getting faulty oxygen data from the sensor, it messes up the air-fuel ratio and combustion. This as we know will result in poor combustion efficiency. Which explains why your car is shaking when you’re parked or at the red light. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/aa9f8dd8-945e-4821-b92c-fcc12d91ac9a/Screen+Shot+2022-08-30+at+1.57.58+PM.png Symptoms - SYMPTOMS OF A BAD OXYGEN SENSOR - poor mpg The fourth symptom of a bad oxygen sensor you might be experiencing is poor gas mileage. Since the oxygen sensor is a huge influencer in the decisions that ECM commands for the fuel injection to achieve the best air-fuel ratio, if it sends a faulty signal of a lean condition or in other words more air less fuel, the ECM will want to add more fuel. This unneeded extra fuel is the reason why you have to stop by the gas station more often. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/b5e65025-8130-4fac-8a6f-d7de0451073a/Screen+Shot+2022-08-30+at+1.57.13+PM.png Symptoms - SYMPTOMS OF A BAD OXYGEN SENSOR The purpose of the oxygen sensor is to measure the amount of oxygen in the exhaust system. Once this oxygen sensor gets hot enough to function, the ECM (Engine Control Module) uses the data to either add or reduce fuel by controlling the fuel injectors to achieve the perfect air-fuel ratio. For example, if the sensor measures a rich condition, which means more fuel and less air, the ECM is going to reduce fuel. If the sensor measures a lean condition, which means more air and less fuel, the ECM will command more fuel. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/ea384536-0d54-4d4a-a381-83770a4ed199/Screen+Shot+2022-08-30+at+1.58.05+PM.png Symptoms - SYMPTOMS OF A BAD OXYGEN SENSOR - failed emissions The fifth symptom of a bad oxygen sensor is a failed emissions test. Since there is more fuel than what is actually needed, the rest of it has nowhere to go but to go through the catalytic converter and out the tailpipe. Sure, the catalytic converter was designed to reduce harmful gases to the environment but it was never designed to convert a massive amount. This is the reason why you’re failing the emissions test. https://easyautofix.com/symptoms/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7 monthly 0.5 2023-09-05 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/7112ac13-9b90-4d46-9472-d0488a920ead/Screen+Shot+2022-02-12+at+10.16.41+AM.png Symptoms - SYMPTOMS OF A BAD FUEL FILTER The purpose of the fuel filter is to prevent debris from getting into the fuel injectors. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/0e57c71e-9c7a-4e79-aa98-d66672fea19d/Screen+Shot+2022-08-22+at+8.02.17+PM.png Symptoms - SYMPTOMS OF A BAD FUEL FILTER - engine light The first symptom of a bad fuel filter is having an engine light on. Since the fuel filter isn’t electrical, it won’t throw off a specific code but you might get a P0171 code (lean condition), indicating there’s more air than fuel in the combustion process. A lean condition usually leads to misfires, so you might also get a P0300 code (random/multiple misfires). Ensure you can access your car's diagnostic codes by acquiring an OBD2 scanner here. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/1c746a7b-76bd-43d6-a82a-c4065f103e98/Screen+Shot+2022-08-23+at+2.52.27+PM.png Symptoms - SYMPTOMS OF A BAD FUEL FILTER - crank but no start The second symptom of a faulty fuel filter is a crank but no start. You’ll hear the starter turning but it won’t do anything since there isn’t enough fuel to combust and keep the engine going. This only happens if the fuel filter is extremely clogged. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/f4f9c1aa-14d6-4797-b760-6845520c6075/Screen+Shot+2022-08-23+at+2.52.54+PM.png Symptoms - SYMPTOMS OF A BAD FUEL FILTER - engine hesitation The fourth symptom of a malfunctioned fuel filter is engine hesitation. You’ll press down on the gas pedal to increase speed but the car stutters before it moves. This happens due to the lack of fuel not being able to keep up with the demand of air coming into the engine. When the gas pedal is pressed down, the throttle plate opens up to bring in more air. When this happens, the ECM (Engine Control Module) commands more fuel. The problem is that a clogged fuel filter restricts the flow of fuel. This delays the time it takes to transfer fuel from the tank into the injectors. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/41ea2eb7-ca56-473c-9cff-93f23670b2de/Screen+Shot+2022-08-23+at+2.52.42+PM.png Symptoms - SYMPTOMS OF A BAD FUEL FILTER - rough idle The third symptom of a bad fuel filter is a rough idle. While stationary with the car on, you’ll feel the car vibrating. For a car to run its best, it needs to be at the perfect air-to-fuel ratio (14.7 kg air per 1 kg gasoline). A clogged fuel filter restricts fuel from getting to the injectors at the time needed, disrupting this ratio. This is why you may experience a rough idle. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/a7651908-bf07-4559-b1a4-ba8b6e475f57/Screen+Shot+2022-08-23+at+2.53.06+PM.png Symptoms - SYMPTOMS OF A BAD FUEL FILTER - engine stalling The fifth symptom of a bad fuel filter is your engine stalling. Maybe you’ll be driving uphill and it turns off or you press the gas pedal down to increase speed and it results in the same thing. The reason why it stalls out is because the air-to-fuel ratio is too lean. If the fuel filter is clogged it’s going to restrict the amount of fuel needed, resulting in a stalling engine. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/0ba9bb11-7903-4317-8ec2-4ff92e9f6c1f/Screen+Shot+2022-08-22+at+8.00.43+PM.png Symptoms - SYMPTOMS OF A BAD FUEL FILTER The location of the fuel filter will be inside the gas tank or on the fuel line between the fuel pump and the fuel injectors. https://easyautofix.com/symptoms/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb monthly 0.5 2022-11-21 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/0d99598f-4a96-49b4-a2de-6305d956efcc/Screen+Shot+2022-08-19+at+2.12.19+PM.png Symptoms - SYMPTOMS OF A BAD STARTER The purpose of the starter is to turn the engine so that the ECM (Engine Control Module) commands fuel and spark to start the combustion process. This is what makes a cranking noise before the car starts up. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/33fd7b3f-90a4-429d-bd26-94b5aeb06d45/Screen+Shot+2022-08-22+at+10.55.51+AM.png Symptoms - SYMPTOMS OF A BAD STARTER - one-click sound The second symptom of a bad starter is a one-click sound when attempting to start the engine. The click noise you hear is the solenoid activating the plunger to move the pinion gear outward to touch the flywheel. The reason why the starter isn’t turning could be due to an internal electrical issue. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/6765da1d-420d-4135-9ff6-169283284c68/Screen+Shot+2022-08-19+at+2.34.13+PM.png Symptoms - SYMPTOMS OF A BAD STARTER - grinding noise while cranking The fifth symptom of a bad starter you could be experiencing is hearing a grinding noise while cranking. The reason behind this could be due to a damaged pinion gear. If it’s defective, when in motion with the flywheel or flex plate it will make a grinding noise. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/5f327d35-f922-4670-a80c-021ed86e70b2/AdobeStock_213689168.jpeg Symptoms - SYMPTOMS OF A BAD STARTER - starter running but not the engine The fourth symptom of a bad starter could be the starter running but not the engine. You'll hear the starter free spinning. This happens if the starter is turning on but the pinion gear isn't moving out to connect with the flywheel or flex plate to rotate the engine. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/b7b96b2a-e451-4cfb-8f5c-d68d22a0942d/Screen+Shot+2022-08-19+at+2.18.22+PM.png Symptoms - SYMPTOMS OF A BAD STARTER - Slow crank The third symptom of a bad starter you could be experiencing is a slow crank when starting your car. The reason for this could be due to poor contact between the brush and the commutator, restricting the right amount of current needed to produce the motor’s full torque to turn the engine. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/c0cd7a02-2c59-437b-9572-6f4586d693e3/Screen+Shot+2022-08-19+at+2.15.30+PM.png Symptoms - SYMPTOMS OF A BAD STARTER - no crank no start The first symptom of a bad starter is a no crank no start. This is one of the most common symptoms and could happen due to an internal electrical issue. Either the starter solenoid isn’t functioning or the brushes inside the starter are worn out, unable to pass electrical current through the commutator to get the starter turning. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/d41e9a34-0c84-4b89-8261-a350d1e89122/Untitled+design.jpg Symptoms - SYMPTOMS OF A BAD STARTER The location of the starter will be close to the flywheel or the flex plate of the engine. https://easyautofix.com/symptoms/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba monthly 0.5 2023-09-05 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/baad7435-cfcb-49e6-b248-455fccb0798a/Screen+Shot+2022-08-04+at+5.27.03+PM.png Symptoms - SYMPTOMS OF A BAD TRANSMISSION SHIFT SOLENOID - Engine light The first symptom of a bad transmission shift solenoid is having an engine light on. If the transmission control module detects anything wrong with the sensors, it will turn on the engine light to warn the driver and set a diagnostic code. Some cars also come with a transmission light. Here are some codes related to a faulty transmission shift solenoid: P0750 (Shift Solenoid A) P0755 (Shift Solenoid B) P0760 (Shift Solenoid C) P0765 (Shift Solenoid D) P0770 (Shift Solenoid E) Ensure you can access your car's diagnostic codes by acquiring an OBD2 scanner here. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/e5cd030f-00bf-4d24-a661-2d57c2e44b6d/Screen+Shot+2022-08-16+at+8.30.58+PM.png Symptoms - SYMPTOMS OF A BAD TRANSMISSION SHIFT SOLENOID - gear shift delay The second symptom of a bad transmission shift solenoid you might be experiencing is a gear shift delay. This happens because the solenoids can get dirty and clogged over time due to dirty transmission fluid. Having dirty solenoids could reduce the fluid pressure from passing through efficiently, delaying the time for the gear change. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/a10336c8-3a68-4484-88ec-c9207c877a67/Screen+Shot+2022-08-16+at+8.31.25+PM.png Symptoms - SYMPTOMS OF A BAD TRANSMISSION SHIFT SOLENOID - limp mode The last symptom of a bad transmission shift solenoid is your car going into limp mode. Limp mode is a safety feature that protects you and your car. Since the shift solenoid is responsible for changing gears in your car, if it fails your safety will be at risk. That’s why limp mode gets activated. You’ll feel your car a lot slower, your rpm’s and speed will be limited, and usually, you’ll be stuck in second or third gear. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/a5f082e8-01a6-47e1-a825-a31d95f9062d/IMG_2823.jpg Symptoms - SYMPTOMS OF A BAD TRANSMISSION SHIFT SOLENOID The transmission shift solenoid's purpose is to open up and allow fluid to pass through the valve body. The channels inside the valve body lead to the automatic transmission to pressurize clutch packs and bands to activate specific gear changes. These solenoids get activated by the transmission control module, depending on the vehicle’s speed sensors and others. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/284a5bcc-3f2e-4a03-b51a-d121dd5d92b9/Screen+Shot+2022-08-16+at+8.30.43+PM.png Symptoms - SYMPTOMS OF A BAD TRANSMISSION SHIFT SOLENOID The transmission shift solenoid will typically be located underneath the transmission oil pan around the valve body. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/2e54a5b2-30f3-4945-8b23-37bce9384ec0/Screen+Shot+2022-08-16+at+8.31.09+PM.png Symptoms - SYMPTOMS OF A BAD TRANSMISSION SHIFT SOLENOID - Can’t shift gears The third symptom of a malfunctioned transmission shift solenoid is your transmission not being able to change gears.

When the ABS module disables the anti-lock braking system, the brakes would be unable to pulsate when braking hard. As a result, the brakes will lock up. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/53ebb5b5-6e4d-43b4-89ca-97e87ecdb265/Screen+Shot+2022-08-15+at+4.28.57+PM.jpg Symptoms - SYMPTOMS OF A BAD ABS MODULE ABS stands for Anti-Lock braking system. So, what is an ABS module? In simple words, it's the '“brain” of the ABS. The ABS module analyzes data from the brake switch and wheel speed sensors to determine when to cycle the solenoid valves inside the hydraulic control unit to deliver brake fluid to each wheel. This helps to keep your wheels from locking up as you brake. It also minimizes skidding and braking distance, giving the driver better control of the steering wheel. https://easyautofix.com/symptoms/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29 monthly 0.5 2023-09-05 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/9d971a75-23d2-4a82-96cf-fff5edeada28/Screen+Shot+2022-08-10+at+1.13.18+PM.jpg Symptoms - SYMPTOMS OF A BAD THROTTLE POSITION SENSOR The purpose of the throttle position sensor is to measure the position of the throttle plate and send it to the Engine Control Module (ECM).

It will also be connected to the brake booster. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/1660063359008-OK35DO3BXTABBY4ZFPVL/unsplash-image-aiwuLjLPFnU.jpg Symptoms - SYMPTOMS OF BAD BRAKE MASTER CYLINDER - longer braking distance The fifth symptom of a damaged brake master cylinder is a longer braking distance. You'll press down on the brake pedal only to realize that your car is not stopping as fast as it used to. The reason for this could be due to the leaks inside the master cylinder. Since the seals aren’t able to hold the fluid pressure inside the braking system, the master cylinder won't be able to deliver the correct amount of hydraulic force needed to compress the brakes on the rotors or drums to stop the car. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/7048ece1-69b7-4cb0-8b53-0f3e2466b395/Screen+Shot+2022-08-09+at+5.18.40+PM.png Symptoms - SYMPTOMS OF BAD BRAKE MASTER CYLINDER - spongy brake pedal The third symptom of a damaged brake master cylinder is a spongy brake pedal. Having a leak coming from the grommets can let fluid escape and bring air inside the system. Air inside the brake system is what can cause a spongy brake pedal. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/bcdbc689-891b-45a6-adc9-632d435fd08c/Screen+Shot+2022-08-09+at+8.40.27+PM.png Symptoms - SYMPTOMS OF BAD BRAKE MASTER CYLINDER - PEDAL SINKING TO THE FLOOR The fourth symptom of a bad brake master cylinder is the brake pedal sinking to the floor. This could be caused by torn seals inside the master cylinder preventing the system from holding fluid pressure. When the fluid passes through the defective seals you'll feel the pedal sinking. https://easyautofix.com/symptoms/blog-post-title-one-7bx6p-2yxn9 monthly 0.5 2023-09-05 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/9a80dd79-0ca0-45e3-88c5-351657438aad/AdobeStock_469212147.jpg Symptoms - SYMPTOMS OF BAD SPARK PLUGS - Spark plugs will be threaded into the engine underneath the ignition coils in a coil-on-plug ignition system. If you have a four-cylinder engine they will typically be located at the top as shown in the image attached. If you have a 6 or 8-cylinder engine, they could be located on each side of the engine (left/right or front/back). https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/5b55ff83-c103-4352-a35e-d488be7078e0/Screen+Shot+2022-08-04+at+5.27.24+PM.png Symptoms - SYMPTOMS OF BAD SPARK PLUGS - poor Gas mileage The third symptom of bad spark plugs is poor gas mileage. Faulty spark plugs won’t be able to produce a perfect spark. As a result, the MPG (miles per gallon) in your car will drop, leading to you going to the gas station more often and spending more money. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/703b9d0a-4a29-46e1-80c8-84c0ec76b7d2/Screen+Shot+2022-08-04+at+5.27.03+PM.png Symptoms - SYMPTOMS OF BAD SPARK PLUGS - engine light The first symptom of bad spark plugs is having a check engine light on. More specifically you can have a blinking engine light when there is a misfire occurring. If any of these misfire codes pop up P0300 - P0312, your vehicle could have bad spark plugs. Ensure you can access your car's diagnostic codes by acquiring an OBD2 scanner here. It’s important to remember that you can still have faulty spark plugs without the check engine light on. So keep reading this article to learn more symptoms of bad spark plugs. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/4461267d-6dfe-4f83-a7f2-4db382ae6e13/Screen+Shot+2022-08-04+at+5.27.35+PM.png Symptoms - SYMPTOMS OF BAD SPARK PLUGS - slow crank but no start The fifth symptom of worn spark plugs is your car slow cranking with no start. This symptom is not so common but it’s still possible. If 3 out of 4 spark plugs don’t create a spark to ignite the air/fuel ratio, your vehicle is going to have a hard time turning over the engine. In order for your car to start, all spark plugs need to be functioning properly to start combustion and turn the engine. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/5ee07a83-64bf-4b7b-a90d-da030c6dbf6e/Screen+Shot+2022-08-04+at+5.27.14+PM.png Symptoms - SYMPTOMS OF BAD SPARK PLUGS - ROUGH IDLE The second symptom of malfunctioned spark plugs is a rough idle. If you feel your car shaking or vibrating while stationary with the engine running, it could be caused by bad spark plugs. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/7fc0405b-3df9-4814-bf3e-876a944593ae/AdobeStock_402053882.jpeg Symptoms - SYMPTOMS OF BAD SPARK PLUGS - The purpose of spark plugs is in the name. Spark plugs create a spark inside the combustion chamber to ignite the air/fuel ratio. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/785bd4ca-9686-4b11-a940-a9307777a27e/Screen+Shot+2022-08-04+at+5.42.47+PM.png Symptoms - SYMPTOMS OF BAD SPARK PLUGS - lack of acceleration The fourth symptom of faulty spark plugs is a lack of acceleration. If you’re trying to increase speed but notice the vehicle doesn’t move as fast as it used to, it could be caused by worn spark plugs. For example, if your vehicle has 8 spark plugs, and 4 of them fail, you won’t have as much power to accelerate. Imagine, 8 people trying to lift a heavy piece of equipment, and then you lose 4, your manpower will decrease by half and your guys will get much more tired. This is exactly what happens to the engine with defective spark plugs and why you may notice a loss of power. https://easyautofix.com/symptoms/blog-post-title-one-7bx6p monthly 0.5 2023-09-05 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/95d02d99-3db5-4b28-9950-23dea920029b/Screen+Shot+2022-07-31+at+7.11.05+PM.png Symptoms - SYMPTOMS OF A BAD PURGE VALVE - poor gas mileage The fifth symptom of a faulty purge valve is a poor gas mileage. A stuck open purge valve will consistently be bringing fuel vapors into the combustion chamber. A good purge valve will stay closed and only open when it’s commanded by the ECM. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/16831b14-0c08-41ec-907a-5f8eced4c201/AdobeStock_415380521.jpg Symptoms - SYMPTOMS OF A BAD PURGE VALVE - The purge valve is part of the evaporative emission control system (EVAP). The purpose of the purge valve is to open up and transfer fuel vapors from the charcoal canister into the engine where they get burned off in the combustion chamber. This helps to reduce emissions and increase miles per gallon. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/fa1eab9b-732c-44eb-8fbf-629651eca2b0/Screen+Shot+2022-07-31+at+11.14.27+AM.png Symptoms - SYMPTOMS OF A BAD PURGE VALVE - poor engine performance The third symptom of a malfunctioned purge valve is poor engine performance. Similar to a rough idle, if the purge valve is stuck open, it’s going to disrupt the air/fuel ratio (14. 7 kg (air) to 1 kg (gasoline) ), creating more fuel than air in the combustion process. That’s exactly why you may notice your car feeling more sluggish than usual. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/1659252243246-ZM7G6AC5FESYFGDZ4D9M/unsplash-image-f4UbPVbJcjw.jpg Symptoms - SYMPTOMS OF A BAD PURGE VALVE - hard start after fueling The fourth symptom of a bad purge valve is a hard start after putting fuel in your car. The reason for this is because fuel will occupy more space in the tank. This will force fuel vapors to go past the stuck open purge valve and into the engine. This creates an excess of fuel when starting your car. As we know, too much fuel with too little air causes a no-start in your vehicle. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/1659248389161-7Y2K4ITQ6IP4E5OM47I9/unsplash-image-98T88DmDxko.jpg Symptoms - SYMPTOMS OF A BAD PURGE VALVE - ROUGH IDLE The second symptom of a bad purge valve is a rough idle. When you stop at the red light or the stop sign, you’ll feel your car shaking a lot more than usual. If the purge valve gets stuck open, then excessive fuel vapors will flow into the engine. This will create a rich condition since there will be more fuel than air in the combustion process. For the car to run its best, it strives to achieve the perfect air/fuel ratio, which is 14. 7 kg (air) to 1 kg (gasoline). A faulty purge valve disrupts this fuel ratio, this is why you can feel your vehicle idling. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/0c444818-899d-433c-b77c-99464abad523/Screen+Shot+2022-07-31+at+10.02.02+AM.png Symptoms - SYMPTOMS OF A BAD PURGE VALVE - engine light The first symptom of a faulty purge valve is having a check engine light on. The most common trouble codes that can pop up are P0441, P0443, P0444, and P0445. Ensure you can access your car's diagnostic codes by acquiring an OBD2 scanner here. Be aware that you can still have a faulty purge valve with no check engine light, so let’s move on to the next symptom. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/fe1c29bb-1522-4c09-a928-c6501109678d/Screen+Shot+2022-07-31+at+9.36.43+AM.png Symptoms - SYMPTOMS OF A BAD PURGE VALVE - The purge valve will typically be located near the intake manifold. https://easyautofix.com/symptoms/category/easyautofix monthly 0.5 https://easyautofix.com/symptoms/category/cars monthly 0.5

Acceleration - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/70d4bc36-81cf-485d-9033-a269812e7b51/DSC_0319.jpg Car Tips - How To Fix Engine Hesitation During Acceleration - Engine Control module Lastly, your engine control module could be faulty causing your vehicle to accelerate poorly but this should always be the last option. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/b81cd99a-76e3-4c25-9aa7-fa93692ccfd8/Screen+Shot+2024-06-05+at+10.20.17+PM.jpg Car Tips - How To Fix Engine Hesitation During Acceleration - Air Filter The first easiest thing to identify is to check your air filter. If you notice a lot of debris and dust in the filter, it can restrict the air from getting into the engine. This could cause your vehicle to have sluggish acceleration. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/e48ee1e4-7729-4e66-bd59-51af51341f30/AdobeStock_472068210.jpg Car Tips - How To Fix Engine Hesitation During Acceleration - Throttle Body The sixth thing on the list that can cause poor acceleration is the throttle body. The throttle body controls the amount of air entering the engine. If the motor that's responsible for rotating the throttle plate is starting to go bad, it will result in a slower response rate when you press down on the gas pedal. In other situations, it could be the dirt causing the throttle plate to get stuck. It’s recommended that you clean your throttle body every 60,000 to 80,000 miles. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/ab4a8139-fd10-435a-ab9d-68bfcd7709a9/AdobeStock_54574958.jpg Car Tips - How To Fix Engine Hesitation During Acceleration - Turbocharger Another thing that can cause acceleration hesitation is a faulty turbocharger. The turbocharger is responsible for bringing more air into the engine to mix with more fuel to create more power. If it fails, it won’t be able to bring in more air, therefore, the ECM won’t command more fuel. This will cause a lack of power or sluggish acceleration. https://easyautofix.com/cartips/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7-xhwbb-ya3ld-f6yj3-rl88n-9cg5d-4jfpn-a777e-e7sn2-5s6dl-e97ch-93t8n-hljn2 monthly 0.5 2024-06-06 https://easyautofix.com/cartips/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7-xhwbb-ya3ld-f6yj3-rl88n-9cg5d-4jfpn-a777e-e7sn2-5s6dl-e97ch-93t8n-dz6st monthly 0.5 2024-03-14 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/af0feb46-e8d5-4342-a51f-3d7d84da0210/Screen+Shot+2024-03-14+at+6.07.57+PM.png Car Tips - HOW TO REPLACE THE AIR FILTER IN YOUR CAR - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/4af58874-1a34-4137-8567-561d07d1f06b/Screen+Shot+2024-03-14+at+6.07.23+PM.jpg Car Tips - HOW TO REPLACE THE AIR FILTER IN YOUR CAR - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/1710454433787-G00YIRGK4IV5ERFJXT90/clamp.jpg Car Tips - HOW TO REPLACE THE AIR FILTER IN YOUR CAR https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/1710454941594-QGYWQSPBSE0QQWEHKAOA/Screen%2BShot%2B2024-03-14%2Bat%2B6.06.15%2BPM.jpg Car Tips - HOW TO REPLACE THE AIR FILTER IN YOUR CAR https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/eee31df4-528b-4bde-a34f-5ee923205a99/Screen+Shot+2024-03-14+at+6.00.09+PM.png Car Tips - HOW TO REPLACE THE AIR FILTER IN YOUR CAR - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/bcf249ee-a67c-48e1-bfa9-aa29428f4923/Screen+Shot+2024-03-14+at+6.06.40+PM.jpg Car Tips - HOW TO REPLACE THE AIR FILTER IN YOUR CAR - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://easyautofix.com/cartips/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7-xhwbb-ya3ld-f6yj3-rl88n-9cg5d-4jfpn-a777e-e7sn2-5s6dl-e97ch-93t8n monthly 0.5 2024-03-14 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/f34780dd-2efc-44c1-bec6-ea7d8aee6882/Screen+Shot+2024-03-13+at+9.37.00+PM.jpg Car Tips - WHY YOU SHOULD NEVER BUY A NEW CAR - Lower Cost The third reason is the overall lower cost. It might seem obvious, but it's still important to mention. By choosing a used car, you could save thousands of dollars. Let's say you want to buy a brand-new 2024 Toyota Camry. Opting for a 2019 version would still give you that new car feeling without overspending. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/00b93d7e-c934-400a-9b2e-042bbc31d5e1/Screen+Shot+2024-03-13+at+9.36.34+PM.jpg Car Tips - WHY YOU SHOULD NEVER BUY A NEW CAR - Depreciation The first reason is depreciation. Newer cars typically depreciate much faster than used cars. The depreciation is influenced by factors such as make, model, and condition of the vehicle. On average, new cars can lose around 20% of their value within the first year alone. After that first year, the depreciation typically slows down, but the car can continue to lose value over time. By the end of the fifth year, it's not uncommon for a new car to have lost around 50% of its original value. For that reason, buying a used car can be a better option, as used cars have already undergone the most significant depreciation and can offer better value for money. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/f5ec6ccb-cfff-46b6-888c-f30f96c05503/Screen+Shot+2024-03-13+at+9.37.09+PM.jpg Car Tips - WHY YOU SHOULD NEVER BUY A NEW CAR - Lower insurance The last reason you should avoid buying a new car is lower insurance costs. Now obviously, the cost of insurance will depend on the make and model of the car. However, generally, insurance tends to be lower for used cars than for brand-new ones. Considering that you have to pay for insurance monthly, you could not only save money by getting a used car but also save money on insurance. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/590cf513-9424-4121-b4bd-e85dc2812451/Screen+Shot+2024-03-13+at+9.36.54+PM.jpg Car Tips - WHY YOU SHOULD NEVER BUY A NEW CAR - More Reliability Another reason to avoid buying a new car is reliability. It's tough to know if a brand-new car will work well because nobody has driven it yet. But with used cars, you can find out how reliable they are by checking websites about different cars' history. By doing some research, you can find a reliable used car, that fits what you need, and is affordable. That means you can get the right car for you without worrying about it breaking down after a year of owning it. https://easyautofix.com/cartips/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7-xhwbb-ya3ld-f6yj3-rl88n-9cg5d-4jfpn-a777e-e7sn2-5s6dl-e97ch monthly 0.5 2024-03-14 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/c242c6fa-a417-46e7-8263-a7cde2dd5194/sponge-in-girl-s-hand-2023-11-27-05-01-28-utc.jpg Car Tips - 5 THINGS YOU SHOULD NEVER DO TO YOUR CAR - Using Improper Wash Tools So the first thing might be a bit obvious but it’s often overlooked by a lot of people - using the wrong wash tools. By doing this you can significantly damage your vehicle’s exterior. You should always avoid abrasive materials that can leave scratches and swirl marks. Some examples of items you should avoid are old clothes, bath towels, sponges, etc. Go for microfiber cloths, instead. Remember, using the wrong tools can scratch your car and ruin the glossy finish. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/8c59788d-3ad1-489c-80db-7e01724b29bf/woman-in-car-close-up-of-woman-in-formalwear-driv-2023-11-27-05-24-47-utc.jpg Car Tips - 5 THINGS YOU SHOULD NEVER DO TO YOUR CAR - Resting Your Hand on the Gear Shift Let’s move on to the third thing you should never do - resting your hand on the gear shift while driving. This harmless habit can lead to premature wear and tear on your gear shift and transmission components. Instead, always try to keep your hand on the steering wheel or the armrest. By doing so, you'll ensure that your transmission stays in optimal condition, allowing for seamless gear changes and a longer lifespan for your car. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/140534ab-0a79-47d0-b0ec-d70bcdb0c3e9/AdobeStock_2826381.jpg Car Tips - 5 THINGS YOU SHOULD NEVER DO TO YOUR CAR - Overloading Your Keychain The last thing you should never to your vehicle might be a little less obvious, it’s adding too many keys or gadgets to your car’s keychain. While it might seem harmless, the extra weight could cause wear and tear on the ignition switch over time. Always try to keep your keychain light to avoid any unnecessary strain on your car's ignition system. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/ae82128c-4d60-410d-bdba-2d941a560f36/motion-blur-of-modern-car-instrument-panel-dashboa-2023-11-27-05-36-26-utc.jpg Car Tips - 5 THINGS YOU SHOULD NEVER DO TO YOUR CAR - Revving the Engine When Its Cold The second thing you should never do to your car is revving the engine when it's cold. It might seem harmless, but it can actually cause some severe damage to your car's vital components. When you start your car on a chilly morning, give it some time to warm up first. The cold oil needs time to circulate and reach all the necessary parts. By revving too early, you risk putting unnecessary stress on the engine and potentially damaging the piston rings, cylinder walls, or even the connecting rods. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/6403ec01-863e-4a78-9273-c49fc0a1b9d4/Screen+Shot+2024-02-15+at+4.48.59+PM.jpg Car Tips - 5 THINGS YOU SHOULD NEVER DO TO YOUR CAR - Applying the Handbrake Too Tightly The next thing is applying the handbrake too tightly. This one is more than just overkill; it's gonna cause a lot of issues, especially in colder weather. Excessive tension can strain or even snap the handbrake cable, leaving you with an expensive repair bill. During winter, this risk increases as the cable can freeze in an overstretched position. The trick is to apply just enough tension to secure your vehicle, steering clear of unnecessary strain and expenses. https://easyautofix.com/cartips/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7-xhwbb-ya3ld-f6yj3-rl88n-9cg5d-4jfpn-a777e-e7sn2-5s6dl-c7gw3 monthly 0.5 2024-03-11 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/fb947550-69a9-42a1-af82-d8b1b97b8a8d/Screen+Shot+2024-03-11+at+5.41.24+PM.jpg Car Tips - HOW TO USE AN OBD2 SCAN TOOL - onboard monitor test The next feature is an onboard monitor test.

The MAF sensor measures how much air goes into the engine. It helps the engine control module (ECM) decide how much fuel to add for proper combustion. If the MAF sensor is faulty, it can provide wrong air readings, and trigger the P0171 code. Also, sometimes the sensor can just be dirty. Before replacing it, try spraying it with a MAF sensor cleaner and see if it will solve the issue. https://easyautofix.com/codes/blog-post-title-four-hwht7 monthly 0.5 2024-06-05 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/e8e4d7a1-4a3e-4daa-ad30-49d557f3fe94/Screen+Shot+2024-05-31+at+9.21.57+PM.jpg Codes - P0335 Crankshaft Position “A” Circuit Malfunction - Crankshaft position sensor So the first and most obvious cause could be the crankshaft sensor itself. If the sensor is damaged or faulty, the engine control module will set the P0335 code. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/064bcc7d-505e-49d4-a372-70d1551d0be2/Screen+Shot+2024-05-31+at+9.22.42+PM.png Codes - P0335 Crankshaft Position “A” Circuit Malfunction - ECM (engine control module) The last potential cause that can trigger the P0335 code is a faulty ECM. This should be your last option because it’s more rare that the ECM will go bad. However, it’s still possible. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/c6ad555e-11a1-4dca-a650-67aeac198b88/Screen+Shot+2024-05-31+at+9.22.08+PM.jpg Codes - P0335 Crankshaft Position “A” Circuit Malfunction - Wiring The second reason you’re seeing a P0335 code is wiring issues. Torn or damaged wires will prevent proper communication between the sensor and the ECM. When that happens, your engine control module will let you know that something is wrong and trigger the code. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/bf633bbb-6ad5-466e-8237-1a73909a9160/Screen+Shot+2024-05-31+at+9.22.25+PM.jpg Codes - P0335 Crankshaft Position “A” Circuit Malfunction - Connector The third potential cause is a bad crankshaft sensor connector. The connector must be free of corrosion, dirt, and debris to work properly. If any of these are present on the connector, it will block the proper signal and can set the P0335 code. Also, sometimes the connector might just be loose. A simple fix could be to unplug and plug the connector back in. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/2316463a-4266-47ef-a1d7-b3fe6b722933/Screen+Shot+2024-06-05+at+7.39.15+PM.jpg Codes - P0335 Crankshaft Position “A” Circuit Malfunction - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/a4a4ad55-2edd-4451-be75-7d8692b018ce/Screen+Shot+2024-05-31+at+9.08.53+PM.png Codes - P0335 Crankshaft Position “A” Circuit Malfunction - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://easyautofix.com/codes/blog-post-title-one-7bx6p-2yxn9-4yfbh-9my29-jn92r-x8nba-tshhb-mpjw7-xhwbb-ya3ld-f6yj3-rl88n-9cg5d-4jfpn-8ee66-62cjl-ch7ld-ehdpk-hb6xj-45thd-pzjwp-l8p3n-gwlja-3n5zz-9f9hc-w8l6g-ymygg monthly 0.5 2023-05-15 https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/f1a0eda0-d946-427b-9871-3c52d22855ea/Screen+Shot+2023-04-28+at+7.36.43+PM.png Codes - P0300 ULTIMATE GUIDE - clogged fuel filter If the fuel filter is clogged, it’s going to restrict the correct amount of fuel and throw off the air-fuel mixture. A good way to diagnose this issue is to use a fuel pressure gauge. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/269dac7f-f1cb-4df3-94ce-11d0def1ecac/Screen+Shot+2023-04-28+at+7.36.28+PM.png Codes - P0300 ULTIMATE GUIDE - fuel pump The next possibility could be a fuel pump. When the fuel pump starts to go out, it won’t be able to keep up with the demand for air. This lack of fuel pressure will throw off the air-fuel ratio, creating a P0300 code. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/01091149-2c32-40f2-a609-904e50fa686f/Screen+Shot+2023-04-28+at+7.36.59+PM.png Codes - P0300 ULTIMATE GUIDE - clogged/faulty fuel injectors Another fuel-related cause could be clogged or faulty fuel injectors since they are responsible for delivering fuel into the cylinders. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/764b3df9-dd3b-44f3-9eff-cf4d0a960b41/Screen+Shot+2023-04-28+at+7.37.47+PM.png Codes - P0300 ULTIMATE GUIDE - valve cover gasket If the valve cover gasket is torn, it could bring the engine oil into the spark plug wells. This will prevent the ignition coil from sending the correct amount of voltage into the spark plug to create a great spark. This can be intermittent and cause a P0300 code. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/a5ba4c2a-2e5e-488c-a4a6-a7bf2ff22326/AdobeStock_472068210.jpg Codes - P0300 ULTIMATE GUIDE - dirty throttle plate Another cause of the P0300 code could be a dirty throttle plate. A dirty throttle plate could restrict the correct amount of air needed to enter the combustion chambers, disrupting the air-fuel ratio, which causes a P0300 code. You can clean the throttle plate with a carburetor cleaner. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/ddce119e-d952-42ba-a63b-3548d5c3bf16/Screen+Shot+2023-04-28+at+7.38.43+PM.jpg Codes - P0300 ULTIMATE GUIDE - catalytic converter Speaking of exhaust, a clogged catalytic converter can also be the culprit. If the catalytic converter is clogged, it could cause the exhaust gasses to be trapped inside the combustion chamber and prevent proper combustion. This explanation is also similar to a stuck open EGR valve. When the EGR valve is stuck open, it recirculates exhaust gasses into the intake manifold. A continuous flow of exhaust gasses will take up space in the combustion chambers and could throw a P0300 code. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/1713a76c-0827-44b1-ba8b-e736d55d00cd/Screen+Shot+2023-04-28+at+7.38.05+PM.png Codes - P0300 ULTIMATE GUIDE - Spark Plugs/ignition coils Speaking of spark, spark plugs and ignition coils (COP) could also be a culprit since they are the reason the air-fuel mixture ignites in the first place. Keep in mind, it would have to be more than one to go bad to set the P0300 code. If you have an older car you could have a faulty distributor, bad spark plug wires, coil pack, or in some situations the ignition control module under the coil packs. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/6619460a-ed48-4b8a-9b35-6850cb080cfa/Screen+Shot+2023-04-28+at+7.32.13+PM.jpg Codes - P0300 ULTIMATE GUIDE - torn head gasket A torn head gasket can allow unwanted air, oil, or coolant to enter the combustion chamber, preventing it from igniting the air-fuel mixture. A quick way to test to see if you have a blown head gasket is to perform a combustion leak test. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/a439307e-745a-4ca3-828d-d526253c7673/Screen+Shot+2023-04-28+at+7.34.44+PM.jpg Codes - P0300 ULTIMATE GUIDE - dirty maf sensor The next possible cause could be a dirty mass airflow sensor. A dirty MAF sensor can trick the engine control module by giving it a false reading of the airflow going into the engine. If the readings are false, then the ECM will command the wrong amount of fuel. This will result in a bad air-fuel ratio and will cause a P0300 code. https://images.squarespace-cdn.com/content/v1/629f7ee67cfd3442e9e48a02/371e66a9-3848-40a0-b7e1-80e374e08ec4/Screen+Shot+2023-04-28+at+7.35.01+PM.jpg Codes - P0300 ULTIMATE GUIDE - oxygen sensor Another sensor that can trick the ECM is an oxygen sensor. This sensor is also a huge influencer when it comes to the ECM adjusting the fuel. If the oxygen sensor is giving a bad reading to the ECM, it too will throw off the air-fuel ratio and cause a P0300 code. https://easyautofix.com/codes/category/cars monthly 0.5 https://easyautofix.com/codes/category/car+symptoms monthly 0.5 https://easyautofix.com/codes/category/auto monthly 0.5 https://easyautofix.com/codes/category/automotive monthly 0.5 https://easyautofix.com/home daily 1.0 2025-02-08 https://easyautofix.com/privacy-policy daily 0.75 2022-08-07 https://easyautofix.com/contact-us daily 0.75 2022-08-08 https://easyautofix.com/terms-of-service daily 0.75 2022-08-07
