which way does it go,lol.its shaped the same.its for a 95 civic.there is a tiny little bitty itty bitty hole that is on one side,does that little hole go up or down?i guess its the bleeder hole,im not talking about where it actually sits ont he mani and the map sensor sits on it.

il post a pic in a moment.

 

try blowing through it. If you can blow on one face and have air go through, you want that side facing up, away from the engine, towards the MAP sensor, since it's blocking boost.

 

hmm..........well,i cant blow through it with the way that it was on there,meaning that there was no way pressure could have gotten into the map sensor,but i still through a code 3.

what i dont understand..........i cant blow through it,so i dont see how the map is getting any kind of pressure at all.

why did i get a code 3 ?

 

Hope this helps:

The top part of the picture goes towards the TB.

Here is a "how to" as well:

ok,so hole faces up,ok.

what should happen when i blow trough the manifold side,should alot of air come through or hardly any?

 

should the valve move up or down?like as if it where sitting on the manifold.
