GTP Temps sensors?

2005/GTP/140K miles
Temp guage works, but the electric fans don't.
Doe's anyone know were the temp sensors for the electric fans are located?

Note- If I disconnect the temp sensor going to the guage near the thermostat housing, both coolant fans turn on!


1) ECT sensor for engine Temp + PCM
2) Coolant Temp sensor for gauage.

If the guage and temp sending unit works don't fix it, the ECT sensor is probably bad.

How many wires are on the harness of the ECT you disconnected? If there are 3 then that's the same sensor used for the PCM and the instrument cluster.

Do you have any DTC's? Maybe the wiring between the ECT and the PCM is damaged...

The PCM detected the disconnect of the coolant temp guage sensor, trough a code, and told both fans to turn on High.

We replaced the upper/lower heater coolant elbows, and noticed the fans weren't working!

did you make sure it is not a relay. switch it out with another of the same from a different source and see if it come on. replace the coolant temp sensor easy and it is about 14 bucks. if you have a way to scan the car look at the temp readings, if it is reading an odd number than it is bad. i've had some read in the negative and way high.
