Pollution Sensor
WARNING: This page is about a different car, the 2015 Land Rover LR2, 2014 Land Rover LR2, and 2013 Land Rover LR2. However, it is still accessible from the selected car via links, so may be relevant.
The pollution sensor allows the ATC module to monitor intake air for the level of CO (carbon monoxide) and NOX (oxides of nitrogen). The sensor is mounted on the passenger side of the heater casing.
NOTE:
The pollution sensor is an optional fit on vehicles with a dual zone, automatic climate control system.
The pollution sensor is provided an ignition controlled feed from the BJB (battery junction box) and provides one of the following 5 signals to the ATC module based on ambient air quality:
- Static or reduced pollution levels
- Small increase in pollution levels
- Medium increase in pollution levels
- Rapid or large increase in pollution levels
- Sensor fault.
Based on the signal from the pollution sensor, the ATC module is able to control the intake air 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 intake source using the fresh/recirculated air switch on the control panel.
