Cabin Temperature Sensor / Switch: Description and Operation
IN-CAR TEMPERATURE SENSOR
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.
