    i have the exact same codes, plus a cat converter code. faulty gas cap is the first place to look, and cheapest to try.

    I had the check engine light on and took it to a shop. They put it on a reader and then did a "smoke" test? Said it was some kind of evaporation canister or some sort... then was told that the part comes welded to another larger part and it costs $320 for the part plus labor.

    Later found out that a friend's son has a reader and when I put it on I got the same codes of PO441, PO442, and PO446.

    Does anyone have anymore info or experience they can share with these codes or parts mentioned?
