Refrigerant Pressure Sensor (A/C Pressure/Temperature Sensor -G395- / High Pressure Sensor -G65-)
- To check, use the Vehicle Diagnostic Tester in the "Guided Fault Finding" function an. Refer to the Appropriate Wiring Diagram.
- Overview. Refer to OVERVIEW - CONDENSER, VEHICLES WITH HIGH-VOLTAGE SYSTEM .
  NOTE:
  There are different designations, depending on the vehicle. The sensor is designated as High Pressure Sensor -G65- on the Audi A6 e-tron. It exchanges the data with the Thermal Management Control Module -J1024- on this vehicle. On all other vehicles (except for the Audi A6 e-tron), the sensor is designated as the A/C Pressure/Temperature Sensor -G395-. For these vehicles, it exchanges data with the Climatronic Control Module -J255- control head. Refer to the Appropriate Wiring Diagram.
