In-car Temperature Sensor Test

WARNING: This page is about a different car, the 2008 Honda Pilot, 2007 Honda Pilot, and 2006 Honda Pilot. However, it is still accessible from the selected car via links, so may be relevant.

Check for a change in resistance by heating or cooling the sensor with a hair dryer.

Compare the resistance reading between the No. 1 and No. 2 terminals of the in-car temperature sensor with the specifications shown in Fig 1; the resistance should be within the specifications.
