At a minimum, something as simple as your gas cap may be loose, to a failed sensor, wiring, connector, or worse yet, a larger engine problem. Ignoring it if the car runs and drives fine may seem reasonable for some time, but problems will continue to mount.

Here at Autosome, we’re pretty familiar with the light, so we’ve rounded up the 5 most common causes and everything else you need to know when you’re wondering, “Why is myCheckEngineLight on?” Sometimes, multiple sensors send signals, indicating clues that something bigger has gone awry.

If the light flashes, that means you need to pull over immediately as your vehicle has a serious issue that could cause imminent damage. All that you need to check your own light is an OBTAIN reader, which can pull codes that help you find out what’s wrong with your car.

If you don’t have a code reader, keep reading to learn the most common causes, and then bring your car to your local Autosome to find out why your CheckEngineLight is on. While yes, both yourself and AutoZonecan read the engine computers stored codes, and through Fix Finder, determine likely causes based on thousands of mechanics intel, none of these can pinpoint with 100% accuracy exactly why the CEL came on.

A code reader and an ASE-certified Master Tech with thousands of dollars in diagnostic equipment are NOT the same equivalent at all. It’s important to note that some trouble codes can and do lead to an easy result and solution.

Oxygen sensors also live a hard life in +800 degree exhaust temps and are prone to fail once over 80,000 miles. Because of this, this system of lines and valves is closely monitored, and one of the key sealing pieces of this is the gas cap.

Your downstream oxygen sensors carefully monitor the converter’s performance, and if something goes awry, a number of trouble codes based on “Catalyst efficiency” will appear. Things as serious as a blown head gasket can force burned coolant vapor into the exhaust, triggering a catalyst engine code.

If there are any leaks before or after the mass airflow sensor in the intake tract, a light can trigger. Mass airflow sensors are sensitive to oil, dirt, and water vapor, and any contamination on them can trigger a light.

A faulty MAF sensor can cause rich or lean conditions, which can lead to further failures of other parts You will experience reduced performance and fuel economy If your light is on, and you are wondering why, head down to your local Autosome where one of our store associates can help diagnose the issue through our free Fix Finder service.

As stated before, if you need help from a professional to further diagnose an issue, check out our list of preferred shops in your area. Regardless of whether the light is glowing or flashing, you can find out what’s causing the issue by bringing it in for a Fix Finder reading.

Finding out why your CheckEngineLight is on may help you save gas and avoid more problems down the road. This data is analyzed to give you vehicle-specific fix solutions that have been verified from the records of over 5.5 million ASE-Certified technicians.

A flashing CheckEngineLight indicates that your vehicle’s engine is in serious trouble, whereas a steadily lit one means less urgent service is needed. Regardless, it’s easy to find out what the issue is, and taking care of it quickly can save you money, and prevent further damage down to the road.

This computer will make adjustments to your vehicle’s performance to keep your ride running smoothly. When it runs into an issue that the ECU cannot correct, the checkenginelight (CEL) starts glowing.

The engine computer stores a diagnostic code when the light begins glowing. And driving a vehicle that is only partly functional is a can cause a lot of damage over time.

For starters, the light itself is incredibly vague as it can indicate a wide variety of issues. Luckily the system logs diagnostic trouble codes (DTC), but these sometimes only provide a starting-off point for further diagnosis.

The engine service light starts glowing and the driver is left confused, scratching their head to try and make sense of what’s wrong with the vehicle. An OBTAIN tool can read diagnostic trouble codes that communicate what is wrong with your car.

OBTAIN readers and services like AutoZone’s Fix Finder are pretty useful for diagnosing the cause of a glowing CEL. While the light appears the same way regardless of the part or system affected, it does differ depending on severity.

A flashing checkenginelight means that you need to pull over immediately as your vehicle has a serious issue that could cause severe engine damage. The misfires are most commonly caused by defects in the ignition and fuel systems, or inside the engine.

If it stays on for more than 3 days, you may need to double-check your fix or reset the light manually. Pop the hood, disconnect the positive power cable from the battery, and wait 15 minutes.

Then put your key in the ignition and turn it to the on position 3 times to clear the data.

In this case, the Malfunction Indicator (Check Engine) lamp on the vehicle’s instrument panel will light steady on. Remember to return the scan tool to an Autosome employee when finished.

Borrow an OLD reader to get a CheckEngineLight reading with the Autosome Free Fix Finder Service. If you're unsure or unable to execute any of these steps, an Automaker will gladly recommend a shop nearby.

Connect the cable connector from the scan tool to the vehicle's DLC. Troubleshooting: If the reader LCD is blank, there's no power in your vehicle's Data Link Connector.

If replacing the fuse(s) does not correct the problem, see your vehicle's repair manual to locate the proper computer (PCM) fuse or circuit and perform any necessary repairs before continuing. Take note of the year, make, model, engine (if you know it), and mileage of your vehicle.

The Automaker will get the report for you at a Z-Net Terminal, explain the reading, and recommend possible solutions.
