hi,

just remove pressure chamber and discover that a line is unplug,

it's the way it should be or should I plug this line?

in the case i have to plug this line , which effects to not have this line in?


Thanks for your help

 

Pretty hard to tell what that exactly is from your pictures but. . .

In the top picture, it looks like the two check valves of the front of the UIM as well as the purge control check valves are still hooked up. If that's true, the check valve you're looking at is the one that goes to the switching solenoid which in turn feeds to the ACV (if I'm not mistaken). While I have no idea what symptoms that would cause, I'd check the connections using a vacuum diagram off of this site and get everything back the way it should be.

 

I was talking about the green check valve who seems to loose line...

 

So was I. I was just trying to figure out what it was from process of elimination since your picture doesn't shown what that check valve is actually hooked up to. I was saying that it wasn't one of the two off of the front of the UIM because they are pictured in your first picture way in the background - meaning that it has to be the check valve in the switching solenoid vacuum line since that's the only other one of those green check valves.

Any way. . .use a vacuum diagram from the site, figure out what it is for sure, and hook it up right.
