Replacing the pressure sensor

The sensor is screwed onto the threaded fitting of the pipeline through the shut-off valve. Therefore, when removing the sensor for inspection or replacement, it is not necessary to bleed the refrigerant from the system.

You will need a key "for 14".

Follow the steps below to replace the pressure sensor.

1. Disconnect a wire from the minus plug of the storage battery.



2. Press the latch and disconnect the wiring harness block from the sensor.



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

WARNING: Use a wrench of the correct size when loosening or screwing on the sensor to prevent deformation or damage to the sensor housing.

4. Install the new sensor in the reverse order of removal.

NOTE: O-ring A on the threaded fitting of the pipeline, when replacing the sensor, must be replaced with a new one and lubricated with oil for the air conditioning system before screwing on the sensor.

5. Check the tightness and completeness of filling the air conditioning system with refrigerant at a specialized center for servicing automotive air conditioners.
