Evaporator temperature sensor, function - GF83.57-P-2102-02P
WARNING: This page does not describe the selected car, but rather 25 other vehicles, including the 2007 Mercedes-Benz C350, 2007 Mercedes-Benz C280, 2007 Mercedes-Benz C230, 2006 Mercedes-Benz C55, and 2006 Mercedes-Benz C350. However, it is still accessible from the selected car via links, so may be relevant.
The evaporator temperature sensor (B10/6) is located in the air flow behind the evaporator. It passes on its resistance value, depending on the temperature at the evaporator, to the AAC [KLA] control and operating unit (N22) (with code (580) Air conditioning (or Tempmatic for USA) or code (580) Automatic air conditioning) or to the comfort AAC [KLA] control and operating unit (N22/7) (with code (581) Automatic air conditioning or code (581) Comfort automatic air conditioning).
The refrigerant compressor (A9) is switched off when the evaporator temperature reaches approx. 2 °C. This serves to prevent the evaporator from icing up.
