Re: Temp gauge not working and Check Engine Light on.

You can answer your own question, by disconnecting the temp sensor, the code will set and the gage should go to low........now reconnect(do all this without shutting the engine off).......

The problem could be the sensor, or either line to it from the PCM....or the PCM itself, which is very unlikely....
