Humidity 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 ).
Connect the humidity/in-car temperature sensor 4P connector.
Turn the ignition switch to ON (II). Measure the voltage between terminals with the (+) probe on terminal No. 3 and the (-) probe on terminal No. 2 with the connector connected.
