In-Vehicle Temperature/Humidity Sensor - Navigator
WARNING: This page is about a different car, the 2005 Lincoln Navigator and 2005 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
The in-vehicle temperature/humidity sensor operates in the following manner:
- A thermistor in the in-vehicle temperature/humidity sensor measures air temperature inside the passenger compartment.
- A humidity transducer in the in-vehicle temperature/humidity sensor measures in-vehicle humidity.
- A hose and elbow is connected between the plenum chamber and the in-vehicle temperature/humidity sensor.
- Airflow through the plenum chamber creates a venturi-type suction through the hose which draws passenger compartment air through the in-vehicle temperature/humidity sensor and across the thermistor and humidity transducer.
