Pollution Sensor

WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2015 Jaguar XKR-S, 2015 Jaguar XKR, 2015 Jaguar XK, 2014 Jaguar XKR-S, and 2014 Jaguar XKR. However, it is still accessible from the selected car via links, so may be relevant.

Up to 2009 MY, a pollution sensor was installed only on Japanese specification vehicles. From 2009 MY, the pollution sensor is a standard fit in all markets.

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 mounted in the RH front corner of the engine compartment.

The pollution sensor is powered by an ignition controlled voltage feed from the CJB and provides the ATC module with separate signals of hydrocarbon and oxidized gases. With a pollution sensor fitted, the ATC module can control the air intake source to reduce the amount of contaminants entering the cabin. This function is fully automatic, but can be overridden by manual selection of the air source using the recirculation control switch below the TSD.

If there is a fault with the sensor, the ATC module disables automatic operation of the recirculation door.
