Heat guage not working

how can I check this and where? Whats the main issue for it to stop

Check the wire onto the sensor at the front of the intake manifold.

Check the wire is still on your temp sensor check the sensor with multimetre should get a resistance between groung and where the cable goes

both wires on both sensors are still on and tight. Will check with a meter. Anything els? VBecause this problem is like big , maybe a bad ground?

Both sensors? I could be wrong bit according to me there's only one

im sure the wire rat mentioned will be the problem. same happend to me

both sensors wires are good and tight. the sensor to the ecu and the sensor that goes to the heat gauge. Anything else to maybe look at? been having this issue for a long time.

Maybe sensor has gone
