High Pressure Sensor Connector Assignment

High Pressure Sensor Connector Assignment





Terminal - 1 - Ground (GND)

Contact - 2 - signal output (square wave signal to the Climatronic control module (J255) A/C control head )

Terminal - 3 - B+ (terminal "75")

• With harness connector - B - disconnected, the compressor will not switch on.

• High pressure sensor - A - is an electronic control module; it creates a square wave signal, the duty cycle ratio changes with pressure in the refrigerant circuit => [ High Pressure Sensor Pressure Signal ].
