Why is my temperature gauge not moving?

It’s potential that any wire along the path could have come loose, corroded, or been somehow broken that would cause your temperature gauge to stop working.
Why did my temp gauge stop working?
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. Disconnect the temperature sensor’s wiring connector.

How can I tell if my light gauge is hot?
Check the gauge if the needle moves toward “Hot”, the wire from the gauge to the sending unit has an open or bad connection. If it does not move, connect a test light by grounding one end to a good known ground and the other end to positive side of the gauge (typically a pink wire).
