    help p0410 p0430

    I need some help with trouble code p0410 and p0430. I have a 2002 Trans AM Ws6 with 118000 miles. Air pump does kick on and sends air to shutoff valve but from there air does not come out to check valve. The car runs normal. Have not done any mods to my car.

    Secondary Air Injection System Error and Catalyst system efficiency below threshold ( Bank 2 ).
    It may be a cat or an O2. That's about it for me.

    Sounds like the LS6 manifold/valley cover mod with some catted longtube headers to me.

    pull the air pump fuse and have Frost tune it out.

    The air pump system was deleted in 01 yrs and really does nothing. It's a pain because you live under Cali oppression. Having Frost tune it out will let you remove it and the EGR and still pass emissions.

    You may need to have the PCM programmed.
