F 250 4WD Super Duty V10-6.8L VIN Z CNG (2003)
Cabin Temperature Sensor / Switch: Description and Operation
The in-car temperature sensor:
^
is located in the instrument panel to the right of the steering column.
^
contains a thermistor which measures the in-car air temperature and sends that reading to the EATC module.
^
utilizes a venturi system with an aspirator hose running between the in-car temperature sensor and the plenum chamber.
^
Airflow through the plenum chamber creates a suction through the aspirator hose which draws air from the passenger compartment through the
in-car temperature sensor.
