Cabin Temperature Sensor / Switch: Description and Operation
IN-VEHICLE TEMPERATURE SENSOR
The in-vehicle temperature sensor operates in the following manner:
-
a thermistor in the in-vehicle temperature sensor measures air temperature inside the passenger compartment.
-
an automatic temperature control aspirator hose and elbow is connected between the heater core and evaporator core housing and the in-vehicle
temperature sensor.
-
The automatic temperature control aspirator hose and elbow takes air from the heater core and evaporator core housing air stream to create a
suction in the in-vehicle temperature sensor.
-
The suction draws in-vehicle air into the in-vehicle temperature sensor and across the thermistor.
