Where is the sensor for the temperature gauge?
The most common cause of faulty temperature readings is a broken coolant temperature sensor (CTS). The part, which is normally located near a vehicle’s thermostat near the base of the radiator (consult your owner’s manual or repair guide) can get gunked up and fail.
Where is the temperature sensor on a 2005 Pontiac G6?

How do you test a boat temperature gauge?
Connect the “S” terminal to the “G” terminal with a jumper wire with alligator clips on each end. The gauge should read above 240 degrees. The gauge is working fine if it passes these tests. Therefore, the problem is with the temperature sender.
Why is my 2007 Pontiac G6 overheating?
