In-Car Temperature Sensor Test

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 Honda Odyssey, 2016 Honda Odyssey, 2015 Honda Odyssey, 2014 Honda Odyssey, and 2013 Honda Odyssey. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Before testing, check for climate control DTCs (see HOW TO CHECK FOR DTCS WITH 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. 1 and No. 2 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 when you disconnect the humidity/in-car temperature sensor.
