Refrigerant Pressure 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 refrigerant pressure sensor provides the ATC module with a pressure input from the HP side of the refrigerant system. The refrigerant pressure sensor is hardwired to the ECM, which uses the signal to control operation of the A/C compressor and to calculate the additional load on the engine when the A/C compressor is operating. The ECM also broadcasts the refrigerant HP value over the high speed CAN (controller area network) bus to the CJB (central junction box). The CJB relays the signal to the ATC module over the medium speed CAN bus to increase the amount of recirculated air if required.

The refrigerant pressure sensor is located in the refrigerant line between the condenser and the TXV.
