Refrigerant pressure and temperature sensor, function - GF83.40-P-2171-01T

The resistance value of the refrigerant pressure and temperature sensor (B12/2) changes as a function of the refrigerant pressure and the refrigerant temperature.

These determined values are passed on via the driver-side SAM control unit with fuse and relay module (N10/1) to the AAC [KLA] control and operating unit (N22) (in vehicles without code (581) Comfort automatic air conditioning) or to the comfort AAC [KLA] control and operating unit (N22/7) (in vehicles with code (581) Comfort automatic air conditioning).
