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.
