Outside Air Temperature Sensor Test

WARNING: This page is about a different car, the 2006 Honda Odyssey and 2005 Honda Odyssey. However, it is still accessible from the selected car via links, so may be relevant.
  1. Remove the outside air temperature sensor (see OUTSIDE AIR TEMPERATURE SENSOR REPLACEMENT  ).
  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 graph shown in Fig 1; the resistance should be within the specifications.
