What is a cabin temperature sensor?
The in-cabin or in-car temperature sensor is an (NTC), negative temperature coefficient sensor. This means that as temperature increases, resistance in the sensor decreases. These sensors can be located in different areas throughout the vehicle.
Where is the temperature sensor on a thermostat?
The thermostat sensor is located near the evaporator coil that is within the inside of your AC unit. Air moves past the sensor and coil, it takes not of the temperature and will compare it to the desired temperature. The sensor activates the compressor should your home or office need to be cooled.

What should the temp of the coolant sensor be?
Check that the temperature value of the CTS is around 80-90c when the engine is hot. A lot of engine coolant temperature sensors have two wires and the sensor is controlled by Ohm. Get a wiring diagram and find out what ohms you should have at a specific temperature to check the function.
Can a bad coolant sensor cause a car to not start?
Some cars use the engine coolant temperature sensor to control the electric cooling fans. You have two separate temperature sensors for the fans, dashboard gauge, and engine management in most cars. However, if your car has a single sensor, a bad engine coolant temperature sensor may result in your fans won’t start at all.
