Hey franco, this is what I found.

I would say from the article to try the VSV first, if indeed this is the case. I'd find it hard to that the canister could be broken or clogged. Bad news though, I think it may be a dealer only part. Perhaps a junkyard? Its a fairly small component, but I bet it costs a lot. Hope it sheds some light for ya dude.

I've been getting this code every now and then too. Pardon my ignorance, Is this TSB listed above something I can do? Is it easy to replace the VSV?


Thanks.
