In-car 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.

Remove the in-car temperature sensor (see IN-CAR TEMPERATURE SENSOR REPLACEMENT ).
Heat and cool the sensor by holding it in front of the dashboard center vent.
- Measure the resistance with the system set to Max Cool.
- Measure the resistance with the system set to Max Hot.
Compare the resistance reading between the No. 1 and No. 2 terminals of the in-car temperature sensor with the specifications graph shown in Fig 1; the resistance should be within the specifications.
