A/C Pressure/Temperature Sensor 2 -G826-, REMOVING AND INSTALLING: Notes

For all the following work, close the open lines and connections with clean plugs from the Engine Bung Set: VAS6122 .

The A/C Pressure/Temperature Sensor -G395-, A/C Pressure/Temperature Sensor 2 -G826- and A/C Pressure/Temperature Sensor 3 -G827- are identical in construction. Refer to the Parts Information. They are first programmed to their function and component location (addressing of the sensor) through the "basic setting" function corresponding to their layout in the routing using the Vehicle Diagnostic Tester in the "Guided Fault Finding" function.
If the connectors were interchanged, the function of the sensor will continue to be OK until the next basic setting (sensor addressing). However, this sensor will be incorrectly programmed (addressed) during the next basic setting, and the sensor allocation and the use of its measured values in the Thermal Management Control Module -J1024- will be incorrect from that point onward. Use the Vehicle Diagnostic Tester in the "Guided Fault Finding" function.
If the connectors to the sensors were interchanged, these sensors will be incorrectly programmed (addressed) in the basic setting, and the allocation of the sensor and thus the use of their measured values in the Thermal Management Control Module -J1024- will be incorrect. If it is suspected that the connectors are interchanged, check the wire connections to these sensors. Refer to the appropriate Wiring Diagram.
If the sensor is removed from the wires and installed in another wire, this sensor will maintain its old allocation (addressing) until the next basic setting.
