Air drawn from the passenger compartment by the in-car sensor aspirator motor assembly, and flows over the thermistor. The in-car sensor thermistor changes resistance with air temperature. The BCM measures this resistance and calculates the temperature of the air drawn into the ATC Control. The ATC system then makes adjustments to maintain the optimum passenger compartment comfort. Refer to IN-CAR SENSOR ASPIRATOR MOTOR OPERATION table for when the ATC Sensor is operating.
