I took off my UIM to get at a my check valves, suspecting one of them was bad. In the process of removing it, I had two nipples on solenoids snap. I swear if you so much as breath on those things they break. One was to the charge relief solenoid up top and closest to the front of the car. The horizontal nipple is the one that broke. That one loops and connects to a pipe. There is a pipe below it, and I have no idea what connects to that one. The vaccum hose diagram isn't helping me here, so if any of you have an idea, I'd appreciate it. Also, the double throttle solenoid had a nipple break. I had to hunt around for this one, and do not know where the other end goes as of yet. Any help would be appreciated.

check the vaccuum hose diagram that is all over this site... in fact, an active boost issue thread right now has it.

i'd search, but i'm having a good St Paddy's Day!

After pouring over said diagram, I have concluded that one does nothing on my car. It must be for the auto. And I have found that the double throttle loops around to the other side of the UIM. God this car is a pain.

The title says it all. I attempted the ghetto rig with some cold weld until I can get one from Malloy (about 70 bucks, right?). I think I got it right, but in the event that I did not what will this do to the car? And while I'm on the subject of solenoids, can I just leave the ones I disable (double throttle for instance) sitting in the rack without lines hooked up?

Actually if you take them out, you would get a CEL unless you put a resistor on the connector.
And if you have any solenoids unused from the emissions elimination, maybe you could use one of those and swap it with the charge relief one.
Not sure if they're all interchangable, but I thought most if not all of 'em are.

Good luck.

How exactly is the CRV solenoid not working? I am guessing the nipple broke off. If the CRV isn't opening and your are boosting, then the secondary turbo is going to have its output blocked. This could put stress on the turbo, don't know that anyone has ever broken one though. Don't boost till you fix it and you shouldn't have any trouble.

Since this solenoid is just on/off and doesn't do any variable control, it should be interchangeable with the other on/off emmissions solenoids. I think turbo precontrol and wastegate control solenoids are the only variable ones.

so in effect I could swap it with another expendable solenoid? Interesting. But I'll still get a new one from Malloy. I'll probably wind up ordering a whole new set when I clean out that rat's nest, as fragile as they are.

Like most of everyone said, you need to fix the solenoid. This will affect the turbo itself as well as the sequential operation. As for the solenoids that you removed (e.g. double throttle, etc...) you will not get a CEL light if you just unplug them. However, the code is stored in the ecu, but has no affect on driveability or operation. Plugging resistors in the solenoid eliminates the code that is stored in the ECU so you don't have to fish through them when troubleshooting. Again, leaving the solenoids unplugged with no reistors will not yield a CEL.

Why did you post two threads about the same subject?
