I replaced the temperature sensor located on drivers side towards rear of engine make sure to let engine cool down and use a drip pan and it was still not working. If the gauges all read low or erratic there may be an issue with the voltage regulator that feeds the instrument cluster.
No needle gauge reading and --- reading for on board computer for engine temperature. You will need to drain and fill the cooling system as well as test specifically colored wires. Install the new temperature sensor.
Another common reason for a faulty temperature gauge is air making its way into the radiator hoses. The first step in diagnosing this type of issue is to identify the fuse associated with the instrument cluster or gauges. Remove the temperature sensor.
Another reason your reading might be high is you could be losing coolant. Why Are My Car Gauges Not Working. What do you do.

The most common cause of a dead gauge is probably spread or corroded connector terminals then a cut wire. I had the same issue with the temp not reading and AC not working on 2009 HHR.
Bad coolant temperature sensor The most common problem when the car has a faulty engine temperature reading is due to the coolant temperature sensor which is faulty and sends erroneous information to the cluster instrument. Install the new temperature sensor. If all the car gauges have stopped working then this can be caused by a defective car gauge or a blown fuse.
It can also affect the cars overall cooling efficiency. I left my house in the morning and shortly after leaving the AC stopped working. A common reason your car temperature gauge goes up and down and no heat is emitted is that your cooling system is faulty.

One very rare and elusive cause is when someone replaced the sensor and used Teflon tape on the threads to help them seal.
Disconnect the temperature sensors wiring connector. Faulty cluster Another possible problem is that the car has a faulty temperature gauge. The coolant passageway might be blocked with sediments or rust.
Run the engine for about 20 minutes to get it up to temperature or until the gauge says youre running hot. Open the hood and take a look at your coolant tank. It has remained this way.
You should have a service or repair manual written for your specific vehicle prior to attempting these tests. Reconnect the wiring connector.
