Cabin Temperature Sensor / Switch: Description and Operation
The automatic temperature control sensor is located in the instrument panel to the right of the steering column. The function of the ATC sensor is to
measure air temperature inside the vehicle. This is accomplished by:
^
An ATC sensor hose is connected between the A/C evaporator housing and the ATC sensor.
^
The ATC sensor hose takes air from the A/C evaporator housing air stream to the ATC sensor to create suction.
^
The suction draws in-vehicle air into the ATC sensor and across ATC sensor thermistor.
^
The thermistor measures the inside air temperature as a resistance and sends that reading to the EATC climate control assembly.
