    Question Code P1416

    I pulled P1416 - Secondary Air Injection (AIR) System Bank 2 with my scanner. Anyone have any pointers as to what is causing this or any information at all? Thanks in advance.......

    Fairly common - the passenger side air check valve gets clogged w/carbon over time and stops working. About $15??? at the parts store, easy to replace yourself.

    It's the round black valve between the metal air tube coming off the exhaust, then connects to the air hose - right above the #4 cyl coil pack. Can't remember the part number, but it's the same for either side.

    P1416

    I started receiving the P1416 code too. I reset the DTCs to make sure it was not a fluke. It returned the code. I read several threads on this one from 05 and 06. Now it is time to get to work and replace the air check valve. Thanks for the advice and assistance!
