Reset check engine light after oil change - Avalanche Chevrolet Cars & Trucks

Each vehicle model will have instructions in the manual to reset the check engine light when oil change service is performed. You can contact your dealer by phone and ask for the service manager to get instructions to reset the light or refer to your user manual or look up your manual on the Internet and view the instructions there.

The change oil light needs to be reset after each oil change...some shops are not knowledgeable on how to do this...Your owners manual will instruct you how to reset the oil change light...The service engine soon is a catch all for low fluids and other needs...Be sure to check your oil level again...to clear the service engine soon light, you can disconnect either battery cable for 15 minutes then reconnect...if the service engine stays on...then you need to have your Grand Am checked...Auto Zone does a free diagnostic of check engine light codes...:)

In most later vehicles, that light may stay on for a fixed number (it can be 5-50, we have both) of startups of the engine or many have to be manually reset. The engine can't tell the computer that it has fresh oil but will turn the light on after some finite mileage since the last reset for periodic maintenance items such as your oil change, but some items can't reasonably reset the computer; it has to be told that the oil was changed.
Check your manual to find how to reset that warning light and if you no longer have the manual for your vehicle, you can download a copy of it from the Ford website.

FIRST press and release the setup button to display oil life= xxx
then press and hold the reset button for about 2 sec it should then display oil life set to 100%
--------------------------------
Just pressing the reset button when the change oil light comes on while driving will not reset the computer

This should only be indicating time for an oil change. Now, if the red, check engine light comes on, then you have an oil/engine problem.

Possibly the maintenance light wasn't reset when the last change was done. If you don't have the owners manual to check, I found a referenced method (below) to reset it through AMSOIL synthetic oil products. Good Luck

To reset Engine Oil light. Turn the ignition key to RUN with the engine off. Fully press and release the accelerator pedal three times within five seconds. If the Change Engine Oil light is flashing, the system is reset. The light will flash for up to 30 seconds or until the ignition is turned off. If the light comes on again and stays on for 30 seconds at the next ignition cycle, it did not reset. You will need to reset the system again.

TURN THE IGNITION KEY TO RUN WITH THE ENGINE OFF.FULLY PRESS AND RELEASE THE ACCELERATOR PEDAL THREE TIMES WITH IN FIVE SECONDS.YOU HAVE TO DO THIS MORE THAN ONE TIME.ITS NOT GOING TO RESET FIRST TRY BUT DO THIS PROCEDURE.UNTIL THE CHANGE ENGINE OIL LIGHT WILL FLASH WHILE THE SYSTEM IS RESETTING.TURN THE KEY TO OFF.WAIT A FEW SECONDS.START CAR UP TO SEE IF CHANGE OIL LIGHT COME BACK ON.IF YES YOU HAVE TO TRY THE RESET PROCEDURE AGAIN.

Press setup on message center,

at 7000 you should definetly change oil, but depending on the make and model of your vehicle, to shut off of the check engine light will vary from a simple procedure in your owners manual, to having a obd 2 code detecter hooked up to identifie and delete codes
