In-Vehicle Temperature/Sensor - Expedition

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.
• A hose and elbow is connected between the plenum chamber and the in-vehicle temperature sensor.
• Airflow through the plenum chamber creates a venturi-type suction through the hose which draws passenger compartment air through the in-vehicle temperature sensor and across the thermistor.
