Sensor, Ambient Temperature: Description: Description
WARNING: This page is about a different car, the 2015 Fiat 500. However, it is still accessible from the selected car via links, so may be relevant.
The ambient air temperature sensor (2) is a variable resistor that monitors the air temperature outside of the vehicle. The Automatic Temperature Control (ATC) heating and A/C system uses the ambient temperature sensor data to maintain optimum cabin temperature levels. The ambient air temperature sensor is mounted inside the right outside rear view mirror (1) and protrudes out the bottom of the housing.
