Help me locate & troubleshoot PO498 code evap vent valv solen low voltage on 2007 Honda Civic

I got a CEL of PO498- Evap Vent vlv malf ckt low
I checked fuses 23 & 4, they are good. How can I troubleshoot this problem.

I would ohm check the solenoid, and even bench test the solenoid with a 12 volt source, be SURE to use the correct polarity, because the solenoid has diodes that can be damaged if the positive lead is connected to the ground side the solenoid.
