Pollution Sensor (Where Fitted)
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 pollution sensor allows the ATC module to monitor the ambient air for the level of hydrocarbons and oxidized gases such as nitrous oxides, sulphur oxides and carbon monoxide. The sensor is attached to a bracket on the front-end carrier, at the top left corner of the condenser.
The pollution sensor is powered by a battery voltage feed from the ATC module, and returns separate signals of hydrocarbon and oxidized gases.
If there is a fault with the pollution sensor, the ATC module disables the automatic operation of the recirculation door.
