    My truck threw a code yesterday of p1416, which I looked up as (Port Air Circuit Malfunction/ (AIR) System Bank 2) or secondary air pump. I know where the pump is and where the check valve is, but what is Bank 2? Anyone have this before, and know how to fix it? Thanks

    I've got that same code, mine said

    Mfgr controled aux emission controls

    And that seems pretty generic... No idea yet what do do about it. Did you ever hear anything back from anyone?

    Nope! No help from anyone. I still have the code. I keep reseting it and it comes back in a couple days. I think it has something to do with the secondary air injection system on the passenger side. I am going to take of the check valve and replace it and see if that fixes the problem.

    Okay... If you (or anyone else) figure it out, be sure to post the solutions, and I'll do likewise. :)
