Cabin Temperature Sensor / Switch: Description and Operation
The in-car temperature sensor operates in the following manner:
^
A thermistor in the in-car temperature sensor measures air temperature inside the passenger compartment.
^
An automatic temperature control sensor hose and elbow is connected between the plenum assembly and the in-car temperature sensor.
^
The automatic temperature control sensor hose and elbow takes air from the plenum assembly air stream to create a suction in the in-car
temperature sensor.
^
The suction draws in-vehicle air into the in-car temperature sensor and across the thermistor.
