In-car Temperature Sensor Test

WARNING: This page is about a different car, the 2011 Honda CR-V, 2010 Honda CR-V, 2009 Honda CR-V, 2008 Honda CR-V, and 2007 Honda CR-V. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Before testing the sensor, check for HVAC DTCs (see GENERAL TROUBLESHOOTING INFORMATION ).

Remove the in-car temperature sensor (see IN-CAR TEMPERATURE SENSOR TEST ).
Test the in-car temperature sensor while 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 terminals No. 1 and No. 2 of the in-car temperature sensor with the specifications shown in the graph; the resistance should be within the specifications.
