OUTSIDE AIR TEMPERATURE SENSOR TEST

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 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.
