Scan the computer and it will give you all the codes, if you receive an evap leak code along with the p0449, then you should be looking for a leak, otherwise, if you only receive the p0449, replace the vent valve.

Still gotta test the vent valve...not just replace it because a scan tool throws that code..I've seen that code more than once not be vent valve...

Yes, check voltage at the connector first. This is a forum of mostly diy's, not an automotive repair facility with mastertechs. How many have the proper test equipment laying around in their garage? Because it is a cheap and easy repair that most can do at home, IMO it's well worth it. 99% chance that the cvvs replacement corrects the problem, if not then most would have to take it to a repair facility and pay big bucks for diag and repair. Besides, chances are the cvvs will fail at sometime, so replacement is not a bad thing, even if there is a slight chance that it doesn't correct the problem. Remember, it's only around a 20 buck repair to do it at home (if you get it on ebay as posted above), and $200+ at a repair facility.

actually, the 214-2147 has been revised (214-2324) and even cheaper on ebay (low as 15bucks):

however the revised part requires a jumper harness.. 19257603
