Water temp gauge dead

The wires for the temp sensor run across right behind the cam gears. When I last had my valve cover off I had moved the wires and disturbed them, so when I finished and started driving, I would accelerate the temp gauge would drop. So be sure to check the wires as well as the sensor.

I think the only thing the ecu uses the temp sensor for is the warm up cycle.

Hope this helped as well.
