Outside Air Temperature Sensor Test

Outside Air Temperature Sensor Test

'06-07 models

1. Remove the outside air temperature sensor.
2. Dip the sensor in ice water, and measure the resistance. Then pour warm water on the sensor, and check for a change in resistance.
3. Compare the resistance reading between the No. 1 and No. 2 terminals of the outside air temperature sensor with the specifications shown in the graph; the resistance should be within the specifications.




4. If the resistance is not as specified, replace the out side air temperature sensor.
