- Dip the sensor in ice water, and measure the resistance. Then pour warm
water on
the sensor, and check for a change in resistance
- Compare the resistance reading between terminals No. 1 and No. 2 of the
outside
air temperature sensor with the specifications shown in the graph; the
resistance
should be within the specifications
- If the resistance is not as specified, replace the outside air
temperature sensor.
