Ambient Temperature Sensor / Switch HVAC: Testing and Inspection

AMBIENT TEMPERATURE SENSOR INSPECTION

NOTE: Ambient temperature sensor does not detect a sudden change in temperature sensitively caused by driving or stopping the vehicle to stabilize the control of the full-auto air conditioner. Therefore, the measured value may differ from the original value when the resistance of the ambient temperature sensor is measured immediately after the removal.

1. After removing the ambient temperature sensor, leave it to the inspection place for 30 min or more
2. Measure the temperature around the ambient temperature sensor.




3. Measure the resistance between terminals of the ambient temperature sensor.
- If the resistance is not as shown in the graph, replace the ambient temperature sensor.
