1992 toyota Corolla Temp gauge does not work

check wire is connected to temp sensor on the engine

faulty temp sensor

a car parts store can supply the sensor
for your model toyota corolla

It is the sending unit, usually the veryable resister and arm. Remove and replace sending unit. It is , unfortunately, located inside of the fuel tank. To confirm gage operation reverse wiring to the guage and it will reverse the guage, confirming tha the gauge.is ok.

'96 or '89... Usually near the thermostat location.
There is one for the computer and one for the temp gauge.
Ground one of the wires to see if the temp gauge "pegs".

The cluster is the gauges, the speedometer, tachometer , and the warning l;ights. It all is removed as a single package, why it's called a cluster.

The sender has lost contact which is the most common. also the sender could be bad.

unplug the sensor that goes to the gauge and take a wire and put it in one end of the sensor wire and touch the other end to the battery ground or any other engine ground and get someone to see if the temp gauge starts to move if it goes all the way to hot then the sensor is bad and if it does not move the gauge is bad or the the wire from sensor to gauge is bad. good luck let me know if i was any help at all...............

Check if you have spark & fuel when this happens. Are you sure its a carbureted engine?

Find the temperature sensor(usually around the thermostat housing)'disconnect connector and ground it with a test light. Observe the inside gauge. It should slowly go up. If so, change sensor. Do the same for the fuel gauge located on the fuel tank. If gauge move to fill as you groung the sending unit wire, change sending unit. Test the right wire. Ask for further assistance.

theres is most likely a control moduel under the dashboard that controls that.
i would check that..

it seems to be a relay or fuse. or the temperature sensor. it is usually on the radiator or the engine block.
