    This is the second time I've had to fix this. I don't know who builds these solenoids but they should be fired. Here's the part I just used to fix my 2009.5. It's the same as what comes as a piece of 92221384 except the hose barb on the lower connection is different.





    Old part on left, new on right.

    As you know stealers want between $800-1000 to do the install. My driveway mechanic did it in the driveway using a couple of jacksnin an hour and a half. A BIG PIA to do. I used that exact part, your new one. Do you top off your tank alot by any chance? I wonder what made it go bad. Though sometimes it is the front valve on the motor underbthe hood. I changed that first, afterbi changed to a new gas cap....have you tried those first before the big job on the gas tank valve?

    Yeah, the dealership did it for free my first time three years ago because I was still under the bumper-to-bumper warranty. They ordered 92221384, the whole canister. I wasn't gonna pay $800+ to have them fix it this time when a $12 part would do. I didn't even pay for the part because I had a gift certificate (thanks RockAuto). I usually fill up when it gets down to about half a tank. If it were the purge valve under the hood it would be a P0443 code. P0449 points to the vent valve so I went straight to that. I checked the resistance across the coil and it didn't even have continuity so it was obviously bad. The new coil was about 20 ohms.

    Ahh shitt!

    I was one of those who had to pay $800 because my state inspection ran out and there was no time to order parts or anything. So I can look forward to this crap again! I'll try to be prepared the next time.

    And the saga continues. Now mine is throwing the p0449. Guess it is time to get intimate with her undercarriage again.
