In-Car Temperature Sensor Test

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2015 Honda Crosstour, 2014 Honda Crosstour, 2013 Honda Crosstour, 2012 Honda Crosstour, and 2011 Honda Accord Crosstour. 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 HOW TO USE THE SELF-DIAGNOSTIC FUNCTION WITHOUT THE HDS ).

Remove the humidity/in-car temperature sensor (see HUMIDITY/IN-CAR TEMPERATURE SENSOR REPLACEMENT ).
Test the humidity/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. 4 and No. 3 of the humidity/in-car temperature sensor with the specifications shown in the graph; the resistance should be within the specifications.

If the resistance is not as specified, replace the humidity/in-car temperature sensor (see HUMIDITY/IN-CAR TEMPERATURE SENSOR REPLACEMENT ).
Clear any DTCs set when you disconnected the humidity/in-car temperature sensor.
