5 Easy Steps to Clear Your Check Engine Light

How to Clear Check Engine Light

The check engine light is a warning light on your dashboard that indicates a problem with your vehicle’s engine. It can be caused by a variety of issues, from a simple misfire to a more serious problem. If the check engine light comes on, it’s important to have your vehicle checked by a qualified mechanic as soon as possible.

There are a few ways to clear the check engine light, but the most common way is to use an OBD II scanner. An OBD II scanner is a device that plugs into your vehicle’s OBD II port and reads the diagnostic trouble codes (DTCs) stored in your vehicle’s computer. Once you have the DTCs, you can look them up online or in a service manual to determine what the problem is.

Once you know what the problem is, you can fix it and then clear the check engine light. In some cases, you may be able to clear the check engine light by simply resetting the computer. However, if the problem is more serious, you may need to have the vehicle repaired.

Here are the steps on how to clear the check engine light

1. Locate the OBD II port on your vehicle. It is typically located under the dashboard, near the driver’s side.
2. Plug the OBD II scanner into the port.
3. Turn on the scanner and select the option to read DTCs.
4. The scanner will display the DTCs. Write down the DTCs so you can look them up later.
5. Fix the problem that is causing the DTCs.
6. Once the problem is fixed, turn off the scanner and unplug it from the port.
7. The check engine light should now be off.

If the check engine light comes back on after you have fixed the problem, it may be necessary to have the vehicle’s computer reset. This can be done by a qualified mechanic.
