Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Sensor, Temperature, In-Car: Operation
Air is drawn from the passenger compartment by the aspirator motor and flows over the temperature thermistor. The thermistor changes resistance with air temperature. The Heating, Ventilation and Air Conditioning (HVAC) module for the Automatic Temperature Control (ATC) system receives the resistance signal over hardwired circuits and calculates the temperature of the air in the passenger compartment. The ATC system then automatically makes adjustments to maintain the optimum passenger compartment comfort.
The in-car temperature sensor cannot be adjusted or repaired and must be replaced if inoperative or damaged.
