    Hi !
    I know I bring back and old thread but I have the exact same issue with my friends truck.
    P0441 and P2420 Codes

    Did you fixed it ? What was it ?

    My gas cap was replaced and the code comes back randomly after about 3-7 days.

    Thanks

    Alex

    Looks like the next thing to try is the charcoal canister.

    If you have gotten anything touched in the air induction area, you should try and push in all air hoses that go in and out of your induction system. Sometimes these hoses aren't push all the way in and it self clears out. I had a similar code on my car referencing evap circuit high code. pushed hoses in and found one slightly out which was triggering the code..
