1998 Geo Tracker 4 cyl Two Wheel Drive Automatic
I have a 1998 GEO Tracker 2wd 1.6L I4. I went thru local emissions and failed. The main reason being that there is “NO" “Check Engine" light with the key on engine off. I’ve only had the car for a short time and have never noticed a check engine light. It also showed P0135 ( 02 sensor heater circuit malfunction-Bank 1) P0340 (Camshaft Position Sensor Circuit Malfunction) P0500 (Vehicle Speed Sensor Malfunction). I recently had a oil leak fixed and the battery was unhooked for this procedure. My questions would be: Is there a particlar fuse path I would search out that would cause there to be no “Engine Light" and is it possible that the same wiring problem has caused all the problems. THE CAR RUNS GREAT ! It starts good and gets to normal operating temp just fine and drives down the road just like everything is normal. I checked the fuse box under the hood to the best of my ability and the fuses appeared to be good. There was no fuse in the ABS slot but when I put a good one into the slot it didn’t make a difference so I am guessing that it doesn’t need that fuse. Any Suggestions….
