A/C pressure sensor
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2006 Volvo S80, 2005 Volvo S80, 2004 Volvo S80, 2003 Volvo S80, and 2002 Volvo S80. However, it is still accessible from the selected car via links, so may be relevant.
A linear pressure sensor is mounted directly on the receiver drier. The pressure sensor has an integrated measurement amplifier that generates an output voltage that is linear to the pressure.
The pressure sensor signal is used to control the following functions:
- the engine cooling fan (FC)
- deactivation of the compressor when pressure is too high
- deactivation of the compressor if the system has run dry of refrigerant.
