L322 Air Compressor Temperature Sensor

The sensor measures the compressor temperature which is measured by the air suspension ecu.

L322 air compressor temperature sensor.

It s the workshop manuals for the l322 s 2 0 hippo apr 22 2015 14. Jun 30 2013. Attached to the compressor is the air dryer which contains a silicate box for removing moisture from the compressed air. Range rover l322 wabco air suspension compressor removal.

3rd dec 2015 4 00pm. Land rover air suspension parts. Vmac temperature sensors switches and controls. The compressor has a temperature sensor located in its housing.

Vmac air compressors are equipped with a switch which includes an oil temperature sensor. It is very common that the piston ring seal within the wabco compressor wears down reducing compressor performance leading to noisy slow rising or even inactive air suspension. Air supplied to inflate the air springs passes through the air dryer. Ok this is the big one.

Does the collective knowledge have any more ideas. Compressor do not fail that often so look at the fuses for the aircon. Discussion in range rover started by johnohp jul 25 2018. Let s start with the absolute basics of how the electronic air suspension system works the air springs are filled with air from the compressor and air reservoir via valves taking control from the electronic air suspension ecu as it takes sensor readings from the height sensors.

This shuts down the system and prevents high temperature related damage. Either that or a failed compressor might yield a working sensor. So they ve suggested it s either the pressure sensor or pump is that the possible answers. When sourcing used or new car air suspension parts its often worth checking part numbers to double check compatibility and avoid any problems.

Likewise check the wiring inside the compressor unit itself if the connector gives no joy. If the compressor oil gets too hot the switch sends a signal to the on off controller to disengage the air compressor s clutch. Genuine parts should be easily identifiable when comparing part numbers and when sourced new or used may come with both. The temperature sensor might be available separately drop meerbusch a pm as he had some wabco contacts supplied rebuild kits with factory parts.

Located on the back side of the compressor is the temperature sensor loosen its screw to free it up. Replacing air suspension parts on a land rover can prolong the life and condition of the vehicle.
