well this started today and I wouldl ike to know what you guys think....I have a code that reads water temp circuit high..I tried resetting the computer and replaced the water temp sensor any other ideas.....hoping not a comp...I also noticed that the water temp reading on my cluster is dead.....after I reset the computer it came back up read above the midline for about a minute without the car being warmed up and then died again and the code came back any ideas are welcome.....

Water temp circuti high, low voltage from sensor is high temp, and high voltage is cold. Thats why your temp gauge isnt working.


Sounds like since #1, its not working on the gauge, #2, the CEL code for it, its shorted to ground someplace
