Air Conditioning Evaporator Temperature Sensor

Air Conditioning Evaporator Temperature Sensor

The air conditioning evaporator temperature sensor mounted to the heater and air conditioning evaporator module has a probe inserted into the evaporator which measures evaporator temperature and sends a signal to the PCM. Within the probe is a thermistor which varies output according to the PCM of the evaporator temperature so the compressor can be disabled before the evaporator freezes. The evaporator temperature sensor is a solid state device, do not attempt to measure resistance. Measuring resistance across pins cause sensor damage.
