A/C Pressure/Temperature Sensor 2 -G826-, REMOVING AND INSTALLING: Removing
- 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- and the A/C Pressure/Temperature Sensor 2 -G826- are identical in construction. Refer to the Vehicle Diagnostic Tester. 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.
- 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.
-- Initiate the A/C system basic setting through the Thermal Management Control Module -J1024- and open the power-activated valves through the stored routine "Extract, evacuate and fill the refrigerant circuit" using the Vehicle Diagnostic Tester.
-- Switch off the ignition.
-- Discharge the refrigerant circuit. Refer to Refrigerant Circuit (Refrigerant R134a Servicing, Refrigerant Circuit, Working with A/C Service Station) or Working with A/C Service Station .
-- Remove the left front wheel spoiler. Refer to OVERVIEW - FRONT WHEEL HOUSING LINER .
-- Disconnect the connector -4-.
-- Check the connection on the refrigerant line -1- for contamination and clean if necessary.
Danger or frostbite due to refrigerant coming out under pressure.
Frostbite on the skin and other parts of the body is possible.
- Wear safety gloves.
- Wear protective eyewear.
- Evacuate or drain refrigerant and open the refrigerant circuit immediately.
- If more than 10 minutes elapse after extracting or draining the refrigerant and the refrigerant circuit was not opened, extract or drain the refrigerant again. Pressure develops in the refrigerant circuit due to evaporation.
-- Loosen and remove the sensor -5-.
-- Seal the open connection on the refrigerant line -1- with clean plugs from the Engine Bung Set:VAS6122 .
