Volkswagen Polo Service & Repair Manual: A/C Pressure/Temperature Sensor -G395

  Note
For switching pressures, removing and installing switches and switch arrangement and version, see vehicle-specific refrigerant circuit.
Refer to → Rep. Gr.87.
  WARNING
There is a danger of ice-up.
Refrigerant will leak out if refrigerant circuit is not discharged.
The refrigerant must be extracted before the A/C Pressure/Temperature Sensor -G395- is removed. If refrigerant circuit is not opened within 10 minutes of extraction, pressure may form in refrigerant circuit due to evaporation. Extract the refrigerant once more.
   
This A/C Pressure/Temperature Sensor -G395- is installed instead of the High Pressure Sensor -G65- or A/C Pressure Switch -F129-.
The pressure signal is always being checked, where the temperature signal is only checked at temperatures above 0 °C (32 °F).
The Climatronic Control Module -J255- operates with this information and controls the coolant fans and activation of the A/C Compressor Regulator Valve -N280-.
