vacuum solenoid question

[poshatch]

its a pretty simple answer i just need to know

so you have the solenoid, and its receives an electric on/off from the ECM to open the plunger or not, and that plunger allows vaccum to flow threw it, and vacuum as we know is a sucking flow going towards the source of the vacuum usually the intake manifold

but ive noticed that every vacuum solenoid ( S.C.V., E.G.R., P.A.I.R.) have a line going into the solenoid and two connected at the other end.

so my question is this...the vacuum sorce is comming from the single one going into the solenoid then when the solenoid is acivated it allows the vacuum to continue into both the other lines that are connected on the opposite end correct???



here is an example lets say were talking about that swirl control solenoid, its recieving vacuum from the line on the left and when activated applies vacuum to the two lines on the right side, top being the swirl valve and the bottom being the FPR, branching off into the lines under the manifold going back to the throttle body (i think) and to the colector on the side by the booster?

correct??????

bump!!

i know some guru on here knows all about solenoids, i need to know asap cause tommorrow im trying to diagnose codes 34 and 32 tomorrow

the solenoid works, the valve works, no reason to be throwing the 32 code unless a bad ecu or wiring

code 34, i fixed the kink in the harness, that should of fixed it but it didnt, switched the knock sensor didnt do anything, got to be the ecu or wiring down the line more

seriously, somebody please help me out! got to get this issue solved

well since nobody was kind enough or informed enough to answer the question, i went ahead and took apart a broken solenoid i had laying around to see how it works

and since nobody answered the question, i figure, for people who stumble across this thread looking for the answer to the question i asked, ill answer my own question

when the solenoid is OFF, recieving no power, the vacuum flows between the hose on the left and the hose on the top

when the solenoid is ON, recieving power, the electromagnet is activated and pull the plunger down, and vacuum flows between the two right hoses

thanks for nothing on this thread NICO!
