In-Vehicle Temperature Sensor - Non-Hybrid

The in-vehicle temperature sensor contains a thermistor, which measures the in-vehicle air temperature and sends that reading to the HVAC module. An aspirator hose is connected between the heater core and evaporator core housing and the in-vehicle temperature sensor. The aspirator hose uses airflow through the heater core and evaporator core housing to create a Venturi-type suction in the hose to draw in-vehicle air through the in-vehicle temperature sensor (across the thermistor).

The in-vehicle temperature sensor is mounted to the instrument panel to the right of the steering column with the aspirator hose connected to the heater core and evaporator core housing near the LH temperature blend door actuator.
