Ambient Temperature Sensor / Switch HVAC: Testing and Inspection

Outside Temperature Sensor

Outside Air Temp. Sensor Location:

1. Remove the fresh air inlet cover.
2. Remove the glove box.
3. Disconnect the 2-pin electrical connector (B10/5x).
4. Remove the outside temp. sensor.
5. Place the sensor next to an accurate temperature gauge (thermometer) and allow enough time for the sensor and the gauge to adjust to the ambient temperature.
6. With a suitable ohmmeter, check the resistance of the sensor.
7. Compare the readings with the temperature chart. Specifications

If the resistance is not within the specified range, replace the outside temperature sensor.
