Outside Air Temperature Sensor Test

  1. Remove the outside air temperature sensor (see OUTSIDE AIR TEMPERATURE SENSOR TEST ).
  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 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.
