Where does the vac line for the pressure sensor on a S5 N/A go? I have looked and looked but can't find any nipples or openings for it.

From the diagram in the haynes manual, it looks like it bridges into a 'Y' connector and both into a single port?

Anyone wanna take a quick look at theirs and tell me?


Thanks in advance.

 

from what see in my book (that is if it is the same one) it plugs in to something under the secondairy injectors
hope this helps

 

Theres a nipple that comes out at an angle under the front secondary injector. That is where the pressure sensor vacuum hose goes.

 

Ok, my angled nipple already has a hose going to it from the spyder that has the 6-port actuator hoses on it. The other side nipple at an angle has a little rubber nubbin over it (block off nub) that was there ever since i bought the car. WTF there is no home for this thing

 

You need to break out the FSM or Haynes, and re-run all your vacuum hoses. It sounds all screwed up. If you dont have the FSM, go download it.

 

Damnit, that's what I was afraid of.

 

Alright, i found it. There's a nipple HIDING under the cold start vavle. Here's a question. Does the pressure sensor go to the nipple at an UPWARD angle near the front secondary injector, or to the nipple at an ANGLE TO THE FRONT underneath the cold start valve.

PS - Do you even need the cold start vavle, my system was unplugged all winter, yet it started fine EVERY time. So i removed the cold start container and unplugged the end that goes to the cold start vavle, car ran fine. So do i need it?

 

Ok PLEASE can someone just pop their hood, and look from the pressure sensor, where the vac tube goes. IF you can see the nipple it goes on, tell me. If it's tucked away under the cold start valve, tell me.

I have the pressure sensor on the nipple under the CSV and another short tube on the one by the front injector. I need to konw if this is right or if it's the other way around. My idle is still shitty unless it's 900-1k (where it's nice and smooth).

 

The nipple you want goes into the front primary intake runner, on the top flange of the lower manifold. The nipple comes out, goes straight up, then bends towards the pressure sensor. Thats the one you want.

 

ok thanks, everything is correct now, vacuum-hose-wise.
