High Pressure Sensor -G65-

WARNING: This page is about a different car, the 2016 Volkswagen Beetle, 2015 Volkswagen Beetle, 2014 Volkswagen Beetle, and 2013 Volkswagen Beetle. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

For switching pressures, removing and installing switches and switch arrangement and version, see vehicle-specific refrigerant circuit.

Refer to REFRIGERANT CIRCUIT .

This High Pressure Sensor -G65- is installed in place of an A/C Pressure Switch -F129-.

The high-pressure sensor generates a square-wave signal or a data telegram when voltage is applied. This signal changes along with pressure in the system.

The downstream control modules (coolant fan control module, ECM), Front A/C Display Control Head -E87- or Climatronic Control Module -J255-, etc.) use this signal to calculate pressure in the refrigerant circuit and to activate the coolant fans and motor and A/C Clutch -N25- or to change the A/C Compressor Regulator Valve -N280- activation.
