Refrigerant Circuit Pressure Sensor -G805-

Installation Location 

Refrigerant Circuit Pressure Sensor -G805- replaces the High Pressure Sensor -G65-. It is located in the high-pressure line between the condenser and the expansion valve. Refrigerant Circuit Pressure Sensor -G805- is connected directly to the Climatic/Climatronic Control Module by a LIN Bus.

Signal Utilization 

The actual refrigerant pressure in the refrigerant circuit and the required engine load is calculated using the signals.

DSO Waveform 

The Digital Storage Oscilloscope (DSO) waveform looks completely different from the previous High Pressure Sensor -G65- waveform.

Effects of Failure 

If the pressure signal fails, the cooling function is deactivated.
