How to Check a Check Engine Light Code

The check engine light is a warning light on your dashboard that indicates a problem with your vehicle’s engine. The light may be accompanied by a number, which is the check engine code. This code can be used to identify the problem and fix it.

To check a check engine code, you will need a code reader. A code reader is a small device that plugs into your vehicle’s OBD-II port. The OBD-II port is located under the dashboard, near the driver’s side.

Once you have the code reader, turn on your vehicle and let it run for a few minutes. Then, turn off the engine and plug in the code reader. The code reader will display the check engine code.

You can then look up the code online or in your vehicle’s owner’s manual to find out what the problem is. Once you know what the problem is, you can fix it and turn off the check engine light.
