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. |
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-. |
