In-Vehicle Temperature and Humidity Sensor - Hybrid

WARNING: This page is about a different car, the 2008 Mercury Mariner and 2008 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

The in-vehicle temperature and humidity sensor contains 2 thermistors, which separately measure the in-vehicle air temperature and humidity and send those readings to the HVAC module. An aspirator hose and elbow is connected between the heater core and evaporator core housing and the in-vehicle temperature and humidity sensor. The aspirator hose uses airflow from the heater core and evaporator core housing air stream to create a Venturi-type suction to draw in vehicle air through the in-vehicle temperature sensor and across the thermistors.

The in-vehicle temperature and humidity sensor is mounted to the RH lower portion of the instrument cluster finish panel.
