Humidity And Temperature Sensor

The humidity and temperature sensor is behind a grill in the instrument panel, on the inboard side of the steering column. The sensor incorporates:

• An NTC thermistor to measure temperature.
• A capacitive sensor element to measure humidity.
• A motor driven fan to draw air through the sensor and over the sensing elements.

Humidity within the passenger compartment is controlled by raising and lowering the evaporator temperature. An increase in evaporator temperature increases the moisture content of the air entering the passenger compartment. Lowering the evaporator temperature reduces the moisture content of the air entering the passenger compartment.
