Evap vent solenoid, back by the gas tank. That's what it sounds like to me. I had the same issue last year on my 06. I have a bunch of info on it here it may help you, I think that I have part numbers and all too.

IIRC what Bigred posted will likely be the fix.

but always start with the gas cap.

It's not the cap. The code says there is a problem with the circuit. That means it's an electrical problem. It's more than likely the purge/vent solenoid itself. You can take it off and put power and ground the the solenoid and it should click.

The system is showing that you need to finish the email verification. You should have received an email from there. Follow the link back to the site and you should be able to see all docs. Just our way of trying to deal with spammers.
