One thing to keep in mind – fuel cools the fuel pump, so if it’s not getting enough fuel, the pump gets overheated, affecting performance.

And the tricky thing with the O2 sensor is that the car will continue to drive well so you might want to dismiss the light. But an O2 sensor code will surely show up in a diagnostic test.

    Why does my Jeep Wrangler not start at all?

    Crank/Cam Sensor- When the cam or crank sensors are not being read by the ECM/PCM, it’s impossible to get the ignition timing right. If you Wrangler does start at all, it’ll run rough. It could be a more serious mechanical issue, such as as bent valve, bad lifter, etc….

In simple terms, this is a device that measures the ability of gas to pass along the exhaust, which includes passing through the diesel particulate filter.

    Driving with a flashing engine light can result in more expensive problems with your engine. One example is if the car is misfiring/not running at all on one cylinder, and you keep driving for a long distance, you can either fill up the catalytic converter with fuel and destroy it.

    When to turn off the malfunction indicator light?

    The DTC will give information about the detected issue. The OBD2 system can turn the MIL off automatically if the conditions for the problem stop to exist.

    Why does my check engine light come on after filling the gas tank?

    Typically if a check engine light comes on after filling the fuel tank, it’s due to a vapor pressure problem. This often is triggered by one of the EVAP system components. This system is designed to filter harmful vapors from the fuel tank.

    This warning light can indicate a wide range of problems, some minor and others much more serious; however, if the light comes on right after filling up, it probably indicates that the gas cap is loose. It is never a good idea simply to assume that the “Check Engine” light is on because the gas cap is loose.

    Why does my Ford capless fuel filler keep filling up?

    Problems with ford capless fuel filler are pretty common since it can get easily damaged. If that happens, the inside of the gas tank will fill up with water every time it rains or when you wash the truck. Furthermore, debris might get inside. To get around this annoying problem, you could get the old dust cap and put it on.

    But if the mechanic diagnoses something that bears no relationship to what the car’s own diagnostic system is saying, that’s reason to be suspicious, she said. A second opinion may be in order. The check engine light can indicate anything from a loose gas cap to something more seriously out of whack deep inside your car.

    What does the light on the engine management light mean?

    This measures the amount of unburnt oxygen passing through the exhaust of the car, which can indicate whether the engine is burning too much or too little fuel. If too little oxygen leaves the exhaust, the engine will be running ‘rich’ – taking too much fuel and not enough air into its cylinders.

    Once again, this can cause the Check Engine light to come on. With your engine off, check your spark plug wires for tiny cracks or holes, especially around the ends of the wires. If they look shabby, you should replace them. 4. Bad or Low Octane Fuel There are a number of cars that are very sensitive to misfires.

    Many cannot, and even the most avid of DIYers need the assistance of professional diagnostics. Your oxygen sensor measures the amount of unburned oxygen in your vehicle’s exhaust system. Oxygen sensors also live a hard life in +800 degree exhaust temps and are prone to fail once over 80,000 miles.

    Many cannot, and even the most avid of DIYers need the assistance of professional diagnostics. Your oxygen sensor measures the amount of unburned oxygen in your vehicle’s exhaust system. Oxygen sensors also live a hard life in +800 degree exhaust temps and are prone to fail once over 80,000 miles.

    Sometimes, multiple sensors send signals, indicating clues that something bigger has gone awry. You can still drive with the light illuminated, assuming the car is running and driving fine, but you should get it checked out as soon as possible.

    A quick trick to determine if a coil is causing a misfire is to simply move the coil and swap with another on the engine. If you have a #2 misfire and move the #2 coil to #4, for example, then the misfire moves to #4, you know the coil is suspect.

    Check The Gas Cap Open the gas cap door. If it is dark, take a flashlight with you. You need to be able to see any damage or crack on the gas cap, so you’ll need additional lighting. Grab the gas-cap handle. Twist it anti-clockwise to open it.

      When one cylinder is not firing correctly, the engine will become unbalanced, and this can cause heavy vibrations inside your cabin on acceleration or at idle. 4. Check Engine Light Modern cars have great monitoring for all the different car sensors on the engine.

      What happens if your check engine light goes off?

      It sends data to the vehicle’s computer, which uses it to regulate the mixture of air and fuel that enters the cylinders. An engine will keep running even if an O2 sensor needs to be replaced, but it will burn more fuel than usual. In the long run, a bad O2 sensor can damage components like the spark plugs and the catalytic converter.

      Is the Check Engine light still lit on Dodge Ram?

      This article applies to the Dodge Ram 2nd, 3rd, and 4th Generation (1994-Present). It’s not uncommon for a check engine light to remain lit long after the issue setting it off in the first place has been fixed.

      A loose gas cap sends an error message to the car’s computer, reporting a leak in the vapor recovery system, which is one aspect of a car’s emissions system. If the fuel cap is loose, tighten it and continue driving. Even so, it will take some time for the light to go off, he says.

      It depends on the severity of the issue. If it’s a minor issue, such as a loose gas cap, it should be safe to drive. If you notice a difference in the performance of the vehicle, it could be an indication of a more serious problem and it’s best to err on the side of caution.
