Have 2006 987 Boxster Base 2.7. Got the Check Engine Light a few days ago and when I attached the ODBCII device received the code identified above. Google search suggests it may be a disconnected or damaged vacuum hose. Does that sound right or is the issue likely something different? There are lots a vacuum hoses on this engine. Does anyone have any experience with this code and if so would you please provide some guidance on where to start looking? For starters, where is the secondary air induction system located? With that information, maybe I could start there with hoses connected to that point. Cheers.
