Sensor, Ambient Temperature: Description: Description
WARNING: This page is about a different car, the 2016 Dodge Durango. However, it is still accessible from the selected car via links, so may be relevant.
The ambient air temperature sensor is a variable resistor that monitors the air temperature outside of the vehicle. The Automatic Temperature Control (ATC) system uses the ambient air temperature sensor data to help maintain optimum cabin temperature levels. The ambient air temperature sensor is mounted to the condenser/radiator closeout, behind the grille.
