Howdy J,
We will assume you mean P0106

My documentation says
P0106 Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance Problem

The MAP / Baro sensors and their exchange solenoid
are located on the pass side strut tower.

Make sure the line from them is connected
to the intake manifold.

You could test the solenoid but testing beyond that
is not in my inventory.

Hope this helps

the hose from that solenoid also has a small in-line filter in route to the intake, it is about 1" circular in shape and has a foam covering. that being clogged will set of the CEL.

the only time i've seen it was a EGR code, but i think in my dealings with that i saw mention of the P0106 related sensor you're referring to.

First, a thaks to Jules for posting this.

Second, a thanks to Gary for mentioning the filter.

Third, I confess to being a big dummie - Red Fox size.

My 97 OB with a 2.2 swap also has this error code.

That is why I knew where to look to take the picture.

Now the big dummie part.

I went out to get a picture for Jules of the filter
and lo and behold.

Mine is hanging on the end of a hose going nowhere!!!

Can anyone tell me where it is suppose to connect.
I saw no open nipples on the intake.

Ya big dummie!!

quit calling my friend skip a dummie!
awesome skip, that's sweet! it runs fine like that?

from memory i believe there's a T fitting from that hose you can see in the same picture. looks like yours might not have it.

the hose i'm speaking of is the one facing the passengers seat parallel to the ground so to speak, at least coming out of the intake it's || to the ground. this hose should have a T fitting that your filter hose connects to.

From the pic, it looks like you have a vacuum hose running from the nipple on intake manifold #3 runner going directly to (I assume) the fuel pressure regulator. There's supposed to be a short piece of hose from that nipple to a T, then the hose from the T continuing to the regulator. The loose hose with the filter should be routed under the intake, and connected to the center nipple of the T.

While you have the hood up, see if there's an emission control diagram pasted to it. It won't show the physical routing, but should give the hose schematic.

Okay, so I'm not as good at this as porcupine73. :)

Anyway, the text says "< T about here", if it can't be read.

Hey Skip.

I have one of each here. A 97 2.5 and a 95 Legacy 2.2. I can look tomorrow. I do think it's basically under the intake for #3 as has been posted.

To give you some idea I think I forgot to replug it back into the T after removing it to place the temperature sensor (for the dash) sensor spade terminal back on - I needed a little more room. I think it's just towards the firewall from the temp sensor.

Then again - my memory isn't always so good - but you knew that.

If you wanna stop by and swap stuff I can make sure both cars are here. We can clear the codes and see what happens.

Dave

Okay guys, Please let me rectify the situation.

First, thanks for the help, I'll email ya Dave.

Second, I'm the big dummie (so called by I)
Here I am, offering all this help
and then standing "nekid" in front of the crowd.
(hangs his head in the shame of it all) thanks Steve if you're watchin'

Third, My man OB99W nailed it with his picture.
(pictures do help, I hope we all learn a lesson from this)
My swapped engine did not have this "T" fitting he shows.

As my penitence..
I will and do so promise to correct this error tomorrow
and post a follow up.

I will just possibly - add a "must check" on EJ25 to EJ22
swaps for all those interested.

We/I owe a thanks once again to Jules for asking
and to Gary
for bringing up the filter.

Thanks to all, I'll go grab a towel now to cover my privates.

I take no credit for the original picture -- it's your pic Skip, which I:
1) downloaded
2) converted to bitmap
3) "Painted"
4) cropped to reduce bandwidth
5) converted back to JPEG
6) uploaded

I'm sure all the manipulation contributed to the blur, but if it got the job done... :)

Old at 33? Wow, John, now you're making me feel really old! :)

From http://www.answers.com/old&r=67 :
1.a Having lived or existed for a relatively long time; far advanced in years or life.

But since it's all relative...
My definition of "old": someone who has at least a few years on you, no matter what your present age. ;)

Or, another definition from the above link:
12. Skilled or able through long experience; practiced.

Yeah, I like that one. :burnout:

hey guys are the 2.5 engines so bad that it's better to just replace it with a 2.2? Usually people want more power, not less. :confused:

You can get the 106 code if you cross the two vacum hoses that go to the solenoids. If you cross them, you only get vacum to the map sensor when the egr valve is open.

I did it once. Figured it out real quick.

It depends what's wrong with the particular 2.5. The 2.5s are prone to piston slap and HG leakage. There's a question as to whether even the latest HGs from Subaru fix the problem. Of course, if the engine was allowed to significantly overheat (due to bad HGs or whatever) or otherwise suffered, putting in one of the more-reliable 2.2s may be the best option for some people. A decent used 2.2 (getting somewhat harder to find as time goes by) may be cheaper than reworking a 2.5 with enough problems.

Could not be better put.
I'll just add
the non-intereference aspect is a draw to some of us.

Good point -- better to be just stranded if a timing belt breaks,
than be stranded and have the possibility of bent valves, etc.

you can get more power out of a built 2.2 than a built 2.5(phase 1)
becouse the 2.5 will blow its gaskets under any kind of boost/compression

I wonder why subaru doesn't offer the 2.2L engine as a cheaper option to the 2.5L on all new cars? It would save them millions on warranty repairs alone.
