    Trouble Codes p0496 and p0455 2007 Escalade EXT

    I already changed the gas cap cause the DIC said to tighten it, so I thought it was bad. Bought a new AC Delco one, same problem.
    Pulled the codes last night and was told:
    P0496 and P0455 are there.
    What do I need to but to fix it.
    Thanks

    You need a purge valve 40$ and a evap canister that had to be modified from Gm poor design this was a mistake Gm made since a canister is suppose to last 20 yr plus. Don't forget the wire adapter can fix for under 200$
