Check engine light is on but it needed an oil change and i got one but the light hasnt gone off, how do i reset it?

The check engine light does not refer to oil changes, this is for emmision and fuel management as well as a diagnostic tool for other engine components. The only wasy to clear this is to have the dealer clear them or repair what ever is causing the light. It will however clear it self after about 20 times of starting the car and the computer not seing any more bad scans from what ever caused the light to come on in the first place. You can have Auto Zone pull the codes from your car and tell you what caused the light to come on in the first place. To clear the aoil change light turn the key on and press the gas pedal 3 times all the way to the floor without the engine running.

What does it mean when my 2003 honda pilots check engine light comes on?

Hi, the check engine light will require you to have the engine CPU scanned for trouble code's. This can only be administered with the assistance of a diagnostic computer scan tool OBD II. You can purchase this tool, at your local auto parts store, or you can just have the scan ran at your local auto zone parts store, free of charge. Once the diagnostic scan is administered, you will be able to isolate the issues that have caused the check engine light.
This scan tool will display a print out code and the location of the issue, on the engine, as well. There are Many issues that will cause the engine light to illuminate, but the most common cause will be a failed monitoring sensor, or sensor harness failure(separated power wire, or ground).
After retrieving the code, it will be interpreted to know what caused the lights to come up and that will be used to fix the problem.

Service engine soon light is on, how to reset

You should go to autozone or advance auto parts stores & get it scanned, usually for free. To get trouble codes stored. If you just want to clear codes without seeing what is wrong, You need to discharge computer memory. Disconnect battery for 2 hours then reattach. Codes will be cleared. If light comes on right away again or over a period of time you need to scan to see what is wrong.

Reduced engine power silverado 2006.Engine light came on.Stopped vehicule shut off engine and restarted.engine light stayed on and had lots of power.

You need to have the computer scanned for trouble codes. Whatever happened stopped after you restarted the engine, but the engine light wont go off until the ignition cycles many times without any problems. Any parts store will scan your truck for free. Have them scan it and clear the codes, and come back here and let us know what code/s you get.

the check engine light means you have a trouble code in your vehicles computer. After fixing the problem with the yukon the check engine light can be reset sometimes by disconnecting the battery and disconnecting the ECM fuse. Although some parts stores are known to check your codes for free they might also clear them with a scan tool.

How to reset check engine light


Normally, the check engine light cannot be reset without a scan tool.
If you have a fault code stored in the memory, the cause for the code needs to be rectified. . You will need a scan tool hooked up to the car to clear the code, once the cause of the code has been repaired..

How do I turn off my check engine light on my Acura TL 99

To turn off the check engine light you have to 1.) Have a scan tool capable of reading your cars computer that has an option to clear any codes stored, or 2.) find out what is causing the check engine light to come on and make repairs.

Even if you clear the code which will turn off the check engine light, and there is a persistent issue, then the check engine light will come back on.

Your best bet is to take it to an auto parts store like Autozone and have them use their scan tool to retrieve the stored code and tell you what it indicates. If that information is not helpful to you then post up the code here and I will see what I can come up with for you.
