Evaporator 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 evaporator temperature sensor is a NTC thermistor that provides the ATC module with a temperature signal from the downstream side of the evaporator. The evaporator temperature sensor is installed in the right side of the heater assembly casing.
The ATC module uses the input from the evaporator temperature sensor to control the load of the A/C compressor and thus, the operating temperature of the evaporator.
