Ambient Air Temperature Sensor
WARNING: This page is about a different car, the 2016 Land Rover LR4, 2015 Land Rover LR4, and 2014 Land Rover LR4. However, it is still accessible from the selected car via links, so may be relevant.
The ambient air temperature sensor is a NTC (negative temperature coefficient) thermistor that provides the ATC module with an input of external air temperature. The sensor is attached to a bracket on the rear of the bumper beam, on the vehicle center-line.
