2. Remove the front bumper (see Removal and installation the front bumper).



3. Press the latch..



4. …and disconnect the wiring harness connector from the sensor.



5. Unscrew the sensor from the threaded fitting on the pipeline.

Caution! When unscrewing and screwing the sensor, use two keys of the appropriate size to prevent the threaded pipe branch from turning or the sensor body from deforming.

6. Install the new sensor in the reverse order of removal and tighten to 7 N·m.

Attention! Sealing ring A when replacing the sensor on the threaded pipe fitting, it should be replaced with a new one and lubricated with air conditioning oil before screwing on the sensor.

Check the condition of the sealing surface on the sensor body. The surface should be clean and smooth. If there are any signs of corrosion, the sensor will have to be replaced.
