    Question tech help needed on Catera temp gauge

    Got a 2001 Catera with a non working temp gauge. Did the basics plus some. Replaced the sensor that the blue wire goes to on the cylinder head under the intake. Ran a new wire from said sensor directly to pin 21 on the IPC connector. Replaced the IPC with a brand new one from dealer, and tried one from salvage.


    If you have the engine warmed up and the key turned to run when you push the cluster in place the gauge will rise and show temperature. If you start the engine it will fall to the peg rest. It won't come back up unless you remove the cluster for a period and reinstall with warmed engine and key on. If you directly ground pin 21 the temperature light will come on in about 5 seconds but the gauge does nothing.

    On the connector only 1 pin has ignition power. Both grounds show good as well as the constant power shown by alldata.

    Any suggestions?

    There is another connection back over the crossover that is the same as the temp sensor.make sure you didn't mix them up.

    We removed the intake and replaced the sensor. Then ran a new wire from the sensor direct to the terminal 21 removing the original wire. It shows the ohms change as the engine warms but does not move the gauge. Thank you for the suggestion.

    You bought a new instrument cluster from the dealer? How much did that set you back? If you plug in an OBDII scanner, see what the engine temp shows from there.
