Cabin Temperature Sensor
The cabin temperature sensor measures air temperature inside the car so the automatic climate control can hold the set temperature.
What is Cabin Temperature Sensor?
It is often hidden behind a small grille in the dashboard, headliner or near the steering column. Many have a tiny fan or use an air stream to pull cabin air across the sensor for an accurate reading. It is usually a thermistor read by the climate control unit.
How it works
The climate unit compares this reading with the target temperature and adjusts heating, cooling and blower speed.
Why it matters for your car
If the small aspirator fan fails or the grille is blocked, the system may heat or cool too much. Air fresheners or objects in front of the grille can affect the reading.
