Refrigerant pressure sensor, function - GF83.40-P-2126-01T

The resistance value of the refrigerant pressure sensor (B12) changes as a function of the refrigerant pressure.

This determined value is passed on by the driver-side SAM control unit with fuse and relay module (N10/1) via Controller Area Network bus class B (interior) (CAN-B) to the AAC [KLA] control and operating unit (N22) (without code (581) Comfort automatic air conditioning) or to the comfort AAC [KLA] control and operating unit (N22/7) (with code (581) Comfort automatic air conditioning).
