Temperature Sensor
Rear Temperature Sensor:
The rear temperature sensor provides an air outlet temperature signal to the rear A/C control module through a two-wire harness lead and connector.
The rear temperature sensor is located in the rear A/C evaporator housing.
The rear A/C temperature sensor is a variable resistor that operates on a five-volt reference signal sent to it by the rear A/C control module. The resistance in the sensor changes as air temperature changes Based upon the resistance in the sensor, a specific voltage on the temperature sensor signal circuit is returned to the rear A/C control module, which is programmed to correspond to a specific temperature.
The rear A/C temperature sensor cannot be adjusted or repaired and, if faulty or damaged, it must be replaced.
