"Most" sensors with a single terminal provide a ground for the circuit.
On an over temp sensor, typically the sensor is open when the temperature is below the danger level.
A simple test would be to remove the wire, the light should go off. Then ground the wire and the light would come on.
If the light goes off, and the temperature is not high, the sensor is bad. If the light stays on, the sensor wire is grounded somewhere, pinched, burned, mouse chewed, somehow it is getting a ground.
If it is a 2 wire sensor, that will usually make the connection between the terminals to turn on the light. It can be tested with a jumper wire across the terminals.
I'm speaking in generalities here, so anything is possible with today's electronics. The signal could be passing through a computer module, so it can get complicated. A shop manual with wiring diagrams would have the answer.
