Evaporator Temperature Sensor / Switch: Description and Operation

EVAPORATOR TEMPERATURE SENSOR

The PCM monitors the evaporator temperature sensor in order to detect a possible evaporator icing condition and to determine in-vehicle temperature.
The PCM disables the compressor clutch if the temperature input does not correspond to a predetermined value.
