Volkswagen Polo Service & Repair Manual: High Pressure Sensor -G65

  Note
For switching pressures, removing and installing switches and switch arrangement and version, see vehicle-specific refrigerant circuit.
Refer to → Rep. Gr.87.
   
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.
