First, confirm your engine isn’t hot by using an external infrared temperature gun.
They are less than $20, follow image for more Details…
Check radiator coolant level. A low level can give false readings.
Then you will need to use a volt meter to check for the negative signal change coming from the sensor to confirm the sensor is working. Typically a direct grounded wire will send a full hot signal and reading on the gauge. If the sensor checks out and the wires are good going to the gauge and the gauge still does not work… replace gauge.
