p0128 i think that was one of the codes. this code was for engine coolant thermostat, and the other was for circuit lost a single for the temp sensor. you ever changed out one of the sensors?
Never overheated, after i replaced the sensor, the code didn;t go away. i drove it for a few days, still didn't go away. I did clear it with a scan tool. even the service manuals don't say much about the code or the sensor.
anybody had issues with coolant temp code? Cleared code, it came back. Replaced sensor and coolant. Oh yea what do you use to get the new sensor in the hole without pinching the o-ring? Code still in it after replacing. What now? :us:
