thats a maintenance light either oil change /spark plugs or air filter or trannsmission oil

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...:)

should have two lights check engine and service engine soon.check engine means there is a malfunction.service soon is reprogrammable,when you change you oil. check you owners manual for reset.

on a 2001 gm i believe you turn the ingition to the run position with the engine off and with-in 3 seconds step on gas pedal 3 times all the way to the floor. the message center should reset and go off. turn key off and then start car. to see if reset.sometimes you have to go slow 3 times to floor with gas pedal.MAKE SURE ENGINE IS NOT RUNNING WHEN YOU DO THE RESET.

It simply means that the service indicator was not reset when the oil was changed. If the oil was changed professionally, then resetting the service indicator is usually part of the job.

It's not just a reminder to change the oil, it's also there to remind you to check/adjust/lubricate/replace other items such as the air filter, oil filter, spark plugs, fuel filter, dampers (UK=shock absorbers) etc.

The service indicator is simply a dumb counter keyed to mileage and time elapsed and cannot sense when you have completed a service. Resetting the indicator requires a special tool so you'll need to take your car to a suitably equipped garage.

A diagnostic scanner that reads OBD1 (the system by which your vehicle processes trouble codes) will be required, many parts stores do this a s a free service. Check with them to see if they charge. Remember though, when they read the car and turn the light off that in order for the light to stay off, the problem must be fixed. Even if it was a one time fluke of a problem, get the code that their scanner gives them so that you know what the issue is.

most any sensor going bad can cause the check engine light to come on,try disconnecting the posative battery cable for 15 seconds ,then put it back on,will reset the codes, or take it to auto zone,they will test your computer for codes at no charge to you.i had a venture van my was ox. sensor. thanks robert b.

meaning you need to change oil and filter in your car .. or if you have done it recently you need to read your manuel in the glove box and see how to reset this service engine soon light.. Jerry holler if you need more

How do you turn off or reset the "Service Engine Soon " light off without taking my Infinity I35 to dealer. Trying to avoid $200.00 dealer charge!
