Volkswagen Golf Service & Repair Manual: High-pressure sender -G65

This high-pressure sender -G65- is fitted in place of the air conditioning system pressure switch -F129-.
When voltage is applied to the high-pressure sender, it generates a square wave signal, or data telegram. This signal changes when the pressure in the system changes.
Using this signal, the control units that are connected in-line (radiator fan control unit, engine control unit, operating and display unit for Climatronic air conditioning system -E87- or Climatronic control unit -J255- etc.) calculate the pressure in the refrigerant circuit and actuate the radiator fan, the engine, the air conditioning system magnetic coupling -N25- accordingly and/or alter actuation from the air conditioning system compressor regulating valve -N280-.
