What would cause my temperature gauge not to work and?
I couldn’t imagine received 3 faulty thermostats. The final result was the Engine Coolant temperature sensor was faulty. It was sending low read reading to the onboard computer. Since the coolant temp sensor was replaced, no problems. 52 people found this helpful.
Why is the temperature sensor not working on my Chevy HHR?
No needle gauge reading and — reading for on board computer for engine temperature. 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. I read how the on board computer can be tricked if any of the other other sensors are not working.
Why is the temperature gauge on my trailblazer not working?
My question is to Ken the Administrator. In a previous blog about 2008 Trailblazer with a temperature gauge intermittently not working and setting code 128, you stated that it traces back to the BCM. Could you kindly explain how the BCM controls this?

What to do if your car temperature gauge is not working?
If your car computer acts as an interface between the sending unit and temperature gauge or warning light, turn the ignition switch off when disconnecting wires from the sending unit, warning light, or temperature gauge. You need to do this to prevent induced-voltage damage to the computer. Consult your vehicle repair manual. 6.
Why is my engine temperature reading so low?
The most common problem when it comes to a faulty engine temperature reading is the coolant temperature sensor itself, sending the information to the cluster. Some cars have two temperature sensors, while other car models have one.
What happens to the temperature gauge when the engine warms up?
The gauge’s indicator shows this by remaining at the low end of the reading range. As engine coolant warms up, the sending unit’s resistance decreases accordingly, and the gauge’s indicator begins to rise. It’ll remain at around the middle of the reading scale, if the engine stays at operating temperature.
