Description
GF83.50-P-3004SX Evaporator Temperature Sensor Of Rear Air Conditioning, Component Description
- with CODE (582) Rear air conditioner
Component Identification
Location
The evaporator temperature sensor is located on the side of the AC housing.
Task
The evaporator temperature sensor measures the temperature of the air flowing past the evaporator. The measured value is read in directly by the AAC
[KLA] control unit (N22/1).
Function
The evaporator temperature sensor is a temperature-dependent resistor. With the aid of the values transmitted to the AAC [KLA] control unit, it can be
prevented that the evaporator in the rear ices up by specifically regulating the rear AC refrigerant shutoff valve (Y67).
