behind your dash board drirectly behind your o2 light you will find a screw below or on top of your light senser and a piece of tape on the other side just remove the tape then remove the screw and put it where the tape was and put the tape onthe old screw hole because you have to change the screw placement every 90,000.0 miles of your vehicles life

On the 1992 Trooper Isuzu considered the Oxygen sensor had a useful life span and after it reached a certain mileage it should be replaced. They say to replace the sensor, remove the instrument panel and there is a reset switch at the back of the instrument panel that needs to be moved to a different position.
