A/C pressure sensor
WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2009 Volvo S60, 2008 Volvo S60, 2007 Volvo S60, 2006 Volvo S60, and 2005 Volvo S60. 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.
