I have a 2005 Outback Wagon 2.5L non-Turbo. A while back, I got a CEL. I read the code and it came back P2009 (Intake Manifold Runner Control (IMRC) Circuit Low (Bank 1)). I also notice that my fuel mileage and power have both diminished. Do you think it's a gummed up tumble generator valve (TGV)? Other people with TGV problems get CEL codes in addition to P2009, but I'm only getting a P2009 error.
I read a lot about the TGV and some posts say that I should clean it. Are there any directions on how to do this quickly or do I need to take the entire intake manifold off like in the TGV deletes procedure?
1) Which side is bank 1? Passenger or driver?
2) How do people get factory service manuals?
Any help would be appreciated! Thx!
