I left mine unplugged for this very reason and have not gotten a code. I was going to plug it next time I had the tank off, but maybe now I shouldn't.
The valve is normally closed so I really don't see the need to plug it, but I would have if I had the right size cap.
I would uncork it and see if the code goes away.
Edit: and by plugging I mean the vacuum port. The electrical connector is still connected.
Many new vehicles have a pressure sensor on the other side of the purge valve and need to see a change in vacuum when the valve is opened otherwise it assumes the canister is plugged and will throw a code. I'm not sure if this system is that complicated as I never looked much past the Purge Control Valve but it may be the reason for your problem.
Please report back.
