05 MAXX LT P0449 Code

[chevy8298]

Hello. So, I got a P0449 code - EVAP system, most likely the vent solenoid. I know the solenoid is on the top of the tank near the back. My question, can I get this off without dropping the tank? Can I get any access to it through the rear wheel well? Anyone done this repair and have any tips?

Trying to determine how much time this is gonna take me. Thanks for any responses.

If I remember right, you have to partially drop the tank on the passenger side....but even then it is a tight fit getting in there, even on a lift....

Saw this was posted a few months ago, but since a lot of people have the same issue thought I'd post a response. I just did the EVAP vent repair on my 05 Malibu Maxx v6.

The best price I found was at gmpartsdirect.com ($14.79 + shipping) and the part #:
25932570 evaporator emissions canister solenoid (2 ports), shown as call-out number 20 and it includes call-out number 21 in the licensed GM parts catalog 1Z03-004 provided in the attachment.

The part is on the right (passenger) side on the top rear of the gas tank. I put the rear of the car on jack stands and supported the tank closer to the driver side with a floor jack. Then removed the bolt on the front of each of the two straps holding the tank. Dropped the tank down as far as it would go and it was still a very tight fit to get my hands on the part.

Was able to unplug the electrical connector with the help of a screwdriver and then slid the whole part rearward until it came off the bracket - really had to work at this as there is little to no room - pulled the tank down and forward on that side while shoving the part rearward and it eventually came all the way off. Then squeezed it down between the tank and the body. Then removed the hose that was connected to it.

Installation was the reverse of what I described above with the exception that I did not fully install the hose until it was on the bracket - just put the hose loosely on it and fished it back into place. Then pulled it forward until it was fully on the bracket and used needle-nose pliers to push the hose on completely until it clicked. Don't forget the electrical connector.

Hope you already got through the repair and hope this helps anyone attempting it. Full time start to finish ~1 hour the first time and then ~30 mins on my wife's uncle's car right after.
