In-Car Temperature Sensor Test

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2014 Honda Ridgeline, 2013 Honda Ridgeline, 2012 Honda Ridgeline, 2011 Honda Ridgeline, and 2010 Honda Ridgeline. However, it is still accessible from the selected car via links, so may be relevant.

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

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