The Other Day I Was Messing Around With My Truck And I Removed The Breather Tube Going To The Turbo. I Fixed A Plug To Keep From Sucking Dust In At The Turbo And Ran A Hose Down Beside The Engine. I Went Up The Road And It Was Fine Til I Nailed It And When I Did I Got This Code Your Getting. I Went Back And Took My Stuff Back Off And Ran The Hose Back From The Valve Cover To The Air Pipe And It Hasent Done It Again. Maybe Check Your Sensor In Top Of The Valve Cover????? The Only Thing I Could Figure Is The Ecm Recognozed Boost Pressure And Somehow Realized No Air Was Being "sucked" Across The Crankcase Pressure Sensor. Maybe It Is Similar To A Mass Air Flow Sensor??
