In-Vehicle 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 in-vehicle temperature sensor is a NTC thermistor installed behind a grill in the instrument panel, on the inboard side of the steering column. The sensor is connected to a tube, the other end of which is connected to a venturi on the side casing of the heater. An air bleed from the heater, through the venturi, induces a flow of air down the tube, which draws cabin air through the grill and over the sensor.
