Sensor, Temperature, In-Car: Operation
WARNING: This page is about a different car, the 2017 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.
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 A/C heater module for the Automatic Temperature Control (ATC) system receives the resistance signal over hard-wired 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.
