Is this an OBD2 system? The transition year was that year and I need to know what you have. Also, what is the problem? It may be something that didn't set a trouble code.

Okay. You may not have any codes stored. Can you explain what the vehicle is doing?

Well I had a mechanic hook it up a couple of years ago and he told me I had a n oxygen sensor not heating up right but I can't remember which one. I want to sell car so I need to take care of this. Thanks

Okay, if the light is on and the vehicle runs properly, chances are it is an emissions related problem. I believe your vehicle only has one heated o2 sensor. If that was the code he found and it has never been replaced, I would just replace it now.
