Basically the solenoids receive power from the main relay and the ecu grounds them to activate as far as I can tell. So to test them I could supply power and ground to see if they switch. I'm going to have to buy a vacuum pump, I've needed one forever lol

FSM test:

Thanks Mahjik :-)

Well got the UIM off tonight, pretty sure my Port air bypass solenoid was unplugged, but I'm not 100% sure. It was stuck underneath the ACV, but I'm pretty sure I wouldn't have been able to get it out had it actually been connected. I pulled the ACV off anyway to have a look at things. Tested all the solenoid valves for resistance all were just around 29 ohms (spec is 27-32 at 68F)

Bought myself a miti vac and checked the air valves in the ACV, both actuated with 15 inHg of vaccum. I heard them open and close with what seemed to be no resistance and could also feel it shut when vacuum was released.

Besides the connector I don't think was connected I also discovered one of the vacuum lines for one the secondary switching valve had a hole in it. I think there is a possibility I did it though when I took the ACV out as it is a tight squeeze to get in and out.

Also this little flapper valve seems to be a bit rusty, though I'm not sure it matters. I did try to clean it a bit.

So I guess my next question is, do you think that if that one connector I think was unplugged would cause the ACV to not function at all? The ECU wouldn't activate any of it because it saw that part of it wasn't working?

Are there any other tests I should do while I have all this stuff apart? If nothing further, I'm going to fix the vacuum line make sure everything is connected and give it a shot.

I had the exact same problem. The hose that goes to MAP sensors was knocked off, hose back on and it worked again.

did you check the a/c fuse under the hood near the front of the car....it powers the airpump too thats what my problem was when i was trying to get mine working
if you just got this car I bet you the fuse is removed

I sold this car a while back. Thanks for the tips though.

lol wortex diggin up old threads FFS

So? No one else can ever again have the same problem? and i didnt see a post where someone says problem solved... I just tought i would try to help fellows with the same problem but it seem that isnt the case in this forum or is it? Or is it better that there is like 10 threads with the same problem? If no one uses the search and old threads these forums will be flooded with new threads.

Im just rassin ya. atleast you search lol

Umm, after I Pulled off the ACV and cleaned it and fixed the vacuum lines I put everything back together. It seemed to be a little better, I determined that it was pumping correctly just that the air pump had poor seals and so the air was escaping back out the intake and was excessively noisy.
