I have a 1994 trooper and the o2 sensor light just came on as I got to 90000 miles. Nothing apears to be wrong with the o2 sensor. Is there a way to reset the o2 sensor indicator and how?

The light comes on at 90k because the gov said it had to. The light is easy to turn off all you have to do is remove the intro cluster and switch the screw to the open hole. both the holes have the same marking on them. Sometime the empty hole has tape over it.

I suppose I am a bit automotive illiterate, but is removing the intro cluster difficult? If not can you give a little description of how to do that?

It's right next to the fitzer valve. Just kidding! :grinno: . You could pull the gauge cluster out, or IIRC- on some models, you can get at it from under the dash with a flashlight & some patients!
