Air Discharge Temperature Sensors

There are 2 air discharge temperature sensors in the EATC system:

There are 4 air discharge temperature sensors in the DATC system:

The air discharge temperature sensors contain a thermistor and are inputs to the HVAC control module. The sensors vary their resistance with the temperature. As the temperature rises, the resistance falls. As the temperature falls, the resistance rises. The HVAC control module uses the sensor information to maintain the desired temperature of the passenger cabin air.
