P0449 Evaporative emission [EVAP] Vent Solenoid

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?

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.

Angry

I'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???

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!! D
