The average aircraft will have temperature gauges for the following:
Outside air temperature, Engine air inlet temperature, Engine exhaust temperature, cabin temperature, and that's just on a small aircraft.
So which temperature gauge do you mean?
If you mean the temp. Gauge in a CAR; it let's you know the temperature of the water in the engine Radiator. If the temp. Gauge is at, or close to, or past the RED mark on the gauge, then the water is TOO HOT which means that it is boiling and turning to steam and most likely to burst one of the rubber hoses that carry the water through the engine casing. It is very very unwise to keep the engine going if the gauge goes to the red mark on it. You will cause expensive damage to the engine if it is not kept cool by the water being circulated by the fan in the front of the engine. Just stop the engine and call a mechanic instantly.
A temperature gauge is used to monitor the temperature of a system or environment. It helps to prevent overheating or prevent freezing by providing real-time information on temperature levels. It is commonly used in vehicles, appliances, and industrial equipment to ensure safe and efficient operation.
replace temperature gauge
That would be the RPM gauge. On an aircraft with variable pitch prop it would be the manifold pressure gauge.
The main purpose of an aircraft propeller is to pull the aircraft through the air. and also to convert the rotational force to thrust or lift.

Defective temperature gauge or defective temperature sensor?
To provide stability of the aircraft during flight!
There are two types of air temperature measurements on aircraft, Ram Air Temperature and Static Air Temperature. (slower aircraft don't normally have RAT gages) Ram Air Temperature, sometimes known as Total Air Temperature, is the air temperature outside the aircraft increased by the heat resulting from the compressibility of the air. The faster the aircraft, the more the rise in the temperature. Static Air Temperature, also known as Outside Air Temperature, is a temperature reading corrected for the compressibility rise to give a true outside air temperature which is used in all sorts of calculations relating to engine performance, aircraft speed, etc.
Bad gauge or defective coolant temperature sensor

Why does your temperature gauge rise and lower only when you have the heat on?
