I have a 2007 Pontiac Grand prix gxp my temperature guage is not working and I have replaced the the temperature guage sensor. What else could be my problem?

Try replacing your thermostat. If it's stuck open, it will not get hot enough to register anything on your gauge.

Good call Reelin68. Also, the gauge itself or the associated wiring could be compromised. I have seen wires get pinched during repairs as well. So you might check that too.
