On my 22re I have a blue,white and brown VSV's on the top of the valve cover. What are the for? I broke one to day and need to get that one replaced.

oh yeah that puts it into perspective! Ok Im about 90% sure the white one is for a/c and has two vaccum lines come off of it that go to the idle up valve on the intake manifold. Im also thinking that the brown one if for fuel pressure and I saw a post were 4crawler did away with it. So correct me if Im worng on this! Just need to figure out what the blue on is for and the brown one.

yeah got the emissions part still dosent tell me anything! so.... the white one is for a/c and the brown one is for the pair valve. So what is the blue one for? Dose it have somthing to do with fuel pressure or anything in that nature?

Try the FSM to which there is numerous links on this website... There is a very good description of what they are for and how they work in the FSM.

 

Blue VSV is for the fuel pressure regulator.

Blue is the FPR, red/brown is PAIR emissions, white is A/C.
