Pollution Sensor (Where Fitted)

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 the center of the upper front crossmember.

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 gas levels. With a pollution sensor fitted, the ATC module can control the air inlet source to reduce the amount of contaminants entering the passenger compartment. This function is fully automatic, but can be overridden by manual selection of the air source using the recirculation switch on the integrated control panel.

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