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. |
|
|
|
| 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. |
