i just returned to my stock intake from aem v2 and i got this CEL. i've searched for xvipers post on which hose goes where but its been deleted or something. if anyone can point out which goes where that would be great

 

The little white check valve is one-way directional. Try flipping it around and resetting the CEL.

This is probably the most common cause if the CEL after a V2 install.

 

that was it. perfect, thanks a bunch
