    2010 is throwing a P0505. I can't find a single thread for the Gen 3's where someone else has this issue. Any suggestions on where to start?

    i found some threads. pat wong suggests starting with throttle body and plate cleaning.

    check engine oil cap o ring, dip stick and pcv hoses for leakage

    I'm normally drawn like a moth-to-a-flame to EGR as culprit, but there is a separate code for that, maybe P0401.

    Attached is the main section, looks pretty deep, requiring Techstream. Wouldn't hurt to check the PCV connections, try replacing PCV valve (it's cheap) and cleaning the throttle body first though.
