The thermostat sensor is located near the evaporator coils. These coils are inside your air conditioner unit. As the air is sucked through the return vents, the air passes by the sensor and the coils. As the air passes the sensor, it reads the temperature and compares that reading to the setting on your thermostat. If the air is warmer then your desired setting, the sensor will activate the ...
A bad thermostat should not cause the temperature sensor to read incorrectly or fail. The sensor will still read whatever temperature the engine is running at, though a bad thermostat can definitely affect what that temperature is. If the thermostat is stuck open (allowing coolant to flow) it can cause the engine to run cooler than normal so obviously the fan wouldn't come on.....but not like ...
