A/C pressure sensor
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2007 Volvo V70, 2006 Volvo V70, 2005 Volvo V70, 2004 Volvo V70, and 2003 Volvo V70. 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.
