I'm also getting a P0449 code. I hear it's fairly common problem on the G6. Does anyone know if it is the vent solenoid or some other part in the system?? I've already changed the gas cap.Greetings,
I'm getting a P0449, it calls out the EVAP Vent Solonid. I've looked in the online parts manuals and have not been able to find the part or any kind of exploded view to determine where the vent solinoid or canister may be located. Any ideas?
Hi Gary, my G6 had the 0449 code and it said evap system, vent solenoid. I tried the gas cap as a cheap try. Then I changed the vent solenoid. Difficult to get at but not too expensive. Still getting the 449 code. Took it to Pontiac dealer and they diagnosed and repaired a broken wire in the harness for 1 1/2 hours labour. All is well now. Hope that helps!! DI'm having the same problem with my 06'. Check engine light keeps coming on. Went to Autozone.. One of the codes that came up was P0449.
It's either a cracked/loose/missing/clogged hose or the canister is malfunctioning. or the vent solenoid? AND it came up "large leak"
I replaced the gas cap and the light went off after a couple of days.. but it came back on and I replaced the gas cap again, and the "check gas cap" light comes on about every day. I click the gas cap 4-5 times after fueling.??
I'm not exactly sure whats wrong???
it's above the fuel tank which u need to drop down on the right side for access (some claim that dropping the tank isn't needed-u decide). i cant help u with part #. i'd imagine there's a how-to by someone on youtube. or u can post an email addy & i'll send a how-to this time. tell that car owner factory service manuals are worth their weight in gold.My question was really to confirm the location and part number of the vent solenoid.
This image does not tell where the Vent Solenoid is located! Please, can you be more Specific on the Location of the Canister Vent Solenoid? So that I may replace it. Any and all assistance will be greatly appreciated. Thank you in advanced!!!# 26 is the one you're talking about. Back at the fuel tank.
its the small round one!! for sure have same junky car! you have to drop the tank its not the big square tank on some missleading sites small round one! check the wires first they run all messed up andbreak short to ground! its a big job pain to drop tank no room under these cars changed mine for nothing canister that is was a wire broke! pontiac is junk they use china cheapest wiring ever to small gauge and cheap! build up resitance! never ever jump these cars or give buddys jumps! i warned you! make your buddy walk!! youll destroyy these cars whole electric systems! gaurunteed gm should be in prison for making these g6 death traps and fire starters! theyve burned down homes just sitting in garage! i can hold in key on any g6 and burn it to ground!! people that have no starts keep trying an dholding key in and this car fries!! smokes and fires! its basically push start but with a key! you crank key and release if you keep holding it three seconds or more its toast!!A Little More.....
Thanks, greenman! I thought that was the case, but I realized that I wasn't quite as explanatory as I should have been.
I was planning on verifying the electrical wiring to the vent solenoid, and change the vent solenoid if needed. My question was really to confirm the location and part number of the vent solenoid.
Some of the online GM catalogs I have seen, including the drawing/diagram excerpts posted here, show a rectangular shape unit near the vapor canister. This is labeled by GM on some of the stuff I can find as a purge solenoid and not a vent solenoid. The drawings on sites such as GMpartsdirect.com only list a purge solenoid. Without any service manuals, I was hoping to glean some info from those, like yourself, that have replaced this.
Based on this, I have been able to locate two sets of part numbers (Rock Auto is an easy one to look at). My problem is that I just wanted to verify that the vent valve (round/cylindrical part) was what is mounted above/next to the gas tank before I tear apart anything.
