Air outlet temperature sensor, component description - GF83.57-P-2130SX
MODEL 216.3, 221.0 /1 up to Model Year 8
Location
The temperature sensors are located at the air conditioner housing, behind the respective air flap.
Task
The temperature sensors measure the temperatures of the air flowing out at the respective air flap and forward these values to the AAC [KLA] control unit (N22/1). The measured temperature value of the vent air is compared by the AAC [KLA] control unit with the required temperature. The corresponding blend air flaps are adjusted depending on the result. During this measurement, the recirculated interior temperature is also recorded.
Function
The temperature sensors are designed as temperature-dependent resistors. As temperature rises, resistance decreases: as temperature drops, resistance increases.
