Sunlight 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 CHECK FOR DTCS WITH THE HDS ).

Remove the sunlight sensor (see SUNLIGHT SENSOR REPLACEMENT ).

Turn the ignition switch to ON (II). Measure the voltage between the terminals with the (+) probe on terminal No. 2 and the (-) probe on terminal No. 4 (with automatic lighting) or No. 1 (without automatic lighting) with the connector connected.
NOTE:
The voltage readings will not change under the light of a flashlight or a fluorescent lamp. Voltage should be:
- 3.6-3.7 V or more with the sensor out of direct sunlight.
- 3.3-3.5 V or less with the sensor in direct sunlight.
If the voltage is not as specified, replace the sunlight sensor (see SUNLIGHT SENSOR REPLACEMENT ).
