Re: 2007 Escalade with engine light on - auto parts store says PO449 code
I got the P0496 Code last week and It was the purge valve and the canister, So the p0449 is something else beside those two. Also the parts department told me that the canister never goes bad and GM had made a poor design choice so there is a replacement for this. I went to autozone and they told me its either the purge valve or canister I just replaced both just in case. I think the canister caused the purge valve to mess up.
