Replacing the pressure sensor (Renault Sandero 1)

The sensor is screwed onto the threaded pipe fitting through a shut-off valve, so when removing the sensor for inspection or replacement, there is no need to bleed the refrigerant from the system.

1. Disconnect the wire from the negative terminal of the battery.



2. Press the lock and disconnect the wiring harness connector from the sensor.

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

Warnings:

• 
• When unscrewing and screwing the sensor, use a wrench of the appropriate size to prevent deformation or damage to the sensor housing A.
• To prevent deformation of the pipeline, use a second key to hold the threaded fitting from turning.

4. Install the new sensor in the reverse order of removal. Tighten the sensor to 7 N·m.

Note.

• 
• When replacing the sensor, the sealing ring A on the threaded pipe fitting should be replaced with a new one and lubricated with air conditioning oil before screwing on the sensor.

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