Howdy Thors, The vent solenoid is located behind the spare tire next to a good sized plastic box. Mine was dirty and dust went everywhere when I pulled it out. It is cylindrical in shape maybe three inches high. It has a black flexible hose and one electrical plug on it. See attached pics. The purge valve...

I hadthat problem on my 2001 Z-71 that code would appear after my wife drove the truck. She wasn't tightening the gas cap enough (till it clicks), after a lesson in gas cap installation I didn't have a problem again (she told me to put in my own damn gas).

I'm not sure how someone on here got both parts for $50. I priced just the EVAP vent valve solenoid, and it's $190 at the dealer ($98 at GM Parts Direct). Anyhow, I have a 2003 Silverado 1500, and I got the P0449 CEL last week. First, what are the ramifications of not fixing this? I think I do smell gas stronger now, though. Second, I think (as my luck would have it) my solenoid is located between the cab...

QUOTE (jaredaggie @ Dec 16 2007, 07:44 PM) Well, cool... I got it fixed, I think. I replaced the EVAP vent solenoid and the purge valve. Both took 3 minutes each and cost 50 bucks total. So far no new CEL. Hi how are you guys I just purchased a Escalade 05....and i have the same code i figure it was the same thing....any ideas on the part number? will it work the same ? or i need to buy a cadillac one? i got an idea of the...

I'm getting a "Tighen Gas Cap" on my digital dash display and a short time later my check engine light comes on. My gas cap is tight and I have to clear the code with my scanner. The light drives me nuts. So what do I need to replace?????????

Try replacing the gas cap.

Im reading a p0449 and 455, I think this is the vent solenoid on my 2003 extended cab 5.3 Silverado, loc ated between the cab and bed, above the fuel tank. Im having a problem finding a "look alike" replacement. Anyone have a part number/ idea of where I can get it other than my dealer? they supposedly dont sell parts to the general public, I think its BS. Here is a picture: This post has been edited by ntavano95 :...

I also had a recent 0449 error that turned out to be the valve. On the 2007 Suburban, it is just in front of the spare tire. Popped it out, $36 for the part at the dealer, and popped the new one in. Cleared the code and away we go. Thanks for the news folks. As an aside, and the main reason for the post, my auto start stopped working once the check engine light came on. Once I changed the valve and cleared the error, the autostart...
