04 GTP Temp Guage Quit Working

I have a 04 Gtp and the temp. guage stop working today while driving down the road. When you shut the car off and start it, it goes through the test and reset, but stays on the bottom. The rest of the guages work. I replaced the sensor on the lower intake, but the fans started running all the time, so the car not running hot. What could I do to make the guage work.
 


I had the same problem. I bought a new sensor but before replacing it, I inspected the wiring and connector. I moved the wires around and taped them up. I disconnected the batery for 15 minutes to reset the PCM and the problem went away. I was able to manipulate the wires to convince myself that it was a loose wire. Never replaced the temperature element and haven't had the problem since. Fans go on due to loss of connectivity with temperature sensor, safe mode.

Good luck and let me know how you make out.
