The pollution sensor allows the automatic temperature control (ATC) module to monitor ambient air for the level of:

Hydrocarbons
Nitrous oxides
Sulphur oxides
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 automatic temperature control (ATC) module, and returns separate signals of hydrocarbon and oxidized gases.

The automatic temperature control (ATC) monitors the signal of air quality returned from the sensor and controls the intake air sourse accordingly to reduce the contamination of the intake air by external pollutants. The intake air source can be overriden by manual selection. If there is a fault with the pollution sensor, the automatic temperature control (ATC) module disables the automatic operation of the recirculation door.
