Question about 2002 Oldsmobile Alero
Even though the engine is running fine ther still may be an issue which is why the light comes on. The first thing to do is pull the codes. his will help identify the system, sensor, or control device that is not working properly. Once youu know why the light is on you can then focus on a repair to that problem. Once the repair is made the codes can be cleared. If the repair was sucessful the light will remian off. If the repair was not successful or a repair is not made or attempted the light will come back on.
you can check codes three ways.
buy a code reader for about $50 and do it yourself.
Call your local parts store and see if they will pull codes for you.
Bring the car in to a service facility and have them run a diagnosis. there is usually a fee for this.
let me know what you find and I'll be happy to help.

You need to have it rescanned. The service engine light will be on for a reason. It could be ABS related, which requires a scanner capable of showing those codes.
