Check engine light P0449 on and off
I recently just had the CEL come on with a p0449 code: Evaporative Emission Control System Vent Valve/Solenoid Circuit Malfunction. I was planning on taking to the dealer Tuesday but after being on for about a day and a half the CEL turned off. I'm curious if the CEL turning off after being on means that the problem doesn't exist anymore? I thought maybe the 2 straight weeks of rain from Hurricane Sandy could have caused some electrical problem to show this error then maybe turned off when it was completely dry. I would much rather skip the 500 dollar repair if there is no major problem. Any help at all would be greatly appreciated, thanks!
I also had this problem about 6 months ago the code was P0306:Cylinder 6 Misfire Detected. The CEL also turned off after about 10 minutes of being lit, so I end up ignoring it. Last edited by Travo; 11-15-2012 at 04:49 PM. |

Check your gas cap first, but may be the solinoid. Time to go to the dealer if emmissions related like this.

The light came back on the other day do I took it to the dealer yesterday. They told me I needed a new purge canister. They were trying to charge $710 with labor, but made a quick call to GM Chevy assistance and they talked with the dealer. They bumped it down to 100 plus tax for the replacement plus labor.
Seems as if this is a problem for a lot of the 2010-2011 models. Probably why GM has helped out with the price, I would recommend going that route if you have the same issue. |

I have headers w/ mid pipes...is the CEL because of the mods? Should I even go to the dealer if I don't have Cat's anymore?

P0449 only has two known causes. Loose gas cap, or bad purge canister/solenoid. If it's the canister or solenoid check Autozone or Advance before you go to the dealer. We recently had the same issue on my dads '03 Impala. The dealer wanted $300 to replace it. I went to Autozone and got the part for $35 and changed it in less then 5 mins. |

Sure enough found the part for the Camaro on Autozone for $28. http://www.autozone.com/autozone/par...ifier=396_0_0_
I don't know exactly where it's at on the Camaro but it's located somewhere near the gas tank. |

The number you posted is the GM part number. My dad's impala was the same way. I took it off and went to the dealer to buy one and the retail on one from GM was $200. I walked out and went to Autozone and they had it for $35. When our issue first arisen I googled "2003 Impala P0449" and there was a lot of sites saying the same thing, that the GM part number was really expansive and they was able to get one at Autozone or Advanced for $30-$40.
