Evaporator Probe: Description and Operation
A/C Evaporator Temperature Sensor
The A/C evaporator temperature sensor, located in the A/C-Heater housing, provides the Body Control Module (BCM) with the evaporator
temperature to prevent the evaporator from freezing. Power for the sensor is provided from the BCM to the sensor on circuit C12. The ground for
the sensor is on circuit C57 to the BCM.
Information on evaporator temperature is sent to the Powertrain Control Module (PCM) across the CCD Bus. The PCM uses this information to
control operation of the A/C compressor clutch.
