OK, I know what P0457 means, and most of the causes. BUT, while I was checking out my EVAP hoses I found out that the blue connector has a fitting on the bottom that has a screw in it. Where does this line go? It's the fitting that faces straight down, not front or rear. Looks like 1/8", maybe 3/16".
The car has a Perrin turbo inlet on it. I do not see any hoses that should be connected to anything. All I need is a location as to where it goes.
