Does this require you to remove the intake manifold on the 07 STI?

No, it does not. To properly remove the solenoid all together, you need to remove the TMIC, but that's about it. However many leave the solenoid mounted and it's electrial connector plugged in since it has the barometric pressure sensor in there. I opted the cut mine off, and removed the solenoid.

Ok, cool. So I would just need to block off the port to the head, and leave the actual valve where it's at, just for the sensor?

Yes, that is the easiest method.

This pressure sensor failure was different. The car ran like crap. I actually thought my tranny was going out, it drove erratically enough to feel like there was a bunch of backlash in the driveline. It reved to 2,500 when starting cold.

I pulled the connector off and 2 of the pins were broken. With the bad connector it read 6 PSI ambient. With the connector disconnected, it read something like 18 PSI. Both are wrong, standard air pressure should be 14.7 plus or minus a bit.

Before I figured this out, I did a relatively tame pull and hit fuel cut, tripping an overboost code. According to my boost gauge my max boost was 16.6 PSI. The map I run is tuned for 18 PSI, so something was definitely not right.

The tuner that I've been using is the head tuner for Cobb, I think he knows his way around an Accessport.

If the 06 runs fine without the valve, it probably means that the pressure sensor is in a different location, or it uses a different tuning philosophy.

Edit: I am cut n pasting part of the explanation my tuner gave me, I don't expect he will mind.


"It does indeed sound like something is amiss with the barometric pressure sensor. 6.2psi barometric pressure would be roughly 22000 feet elevation and I'm guessing you weren't on an airplane when this happened :-D The incorrect atmospheric pressure measurement would have also caused the P0244 as relative manifold pressure is used to determined that code -- it is the "boost cut" feature to minimize the risk of damage if control over boost levels is lost. In this situation, at ~17psi of manifold boost (as per your auxilliary gauge), or ~31psi of manifold absolute pressure, the ECU would see ~25psi of manifold relative pressure (31psi-6.2psi), which is above the threshold I set for setting the P0244 code / inducing boost cut."
Everything seemed to be going well after removing the secondary air injection system until...I threw a P0244 code. After some searching, I found the above post and a series of post replies that look to implicate a faulty sensor.

Upon inspection of the valve connector, I don't have any broken pins. My AP is measuring about 7psi barometric pressure with sensor connected and 21.8psi barometric pressure with sensor disconnected. I presume that because I am not seeing 14-15psi it is a faulty sensor.

northman - if you are still watching this thread, will you give my logic a once over and let me know if you think I need a new sensor (which means a new valve)?

your problems are similar to what I had, the ECU needs correct pressure data to work correctly. Replacing the valve solved my issue. Kind of sucks to pay good money for a valve that you don't even use, but for the sensor.

Anybody know the Part Number?, can't find at oppossedforces.com and the parts local guy asked me if the STi is 5 or 6 speeds------> clueless and he can't order without a ****ing VIN, when I told him it was for a modded Forester, it was the icing on the cake, parts guy =

A little something to add to the instructional library...


I searched this thread, and came up negative for "video" and "youtube", so this looks like it's new to the thread. My apologize if it's been posted before.

Yup. Thanks for the reply.

It was a faulty sensor in the valve. A new valve solved the problem. Barometric pressure now reads 14.7psi.

For a 2007, the SOA part number for the valve with the sensor is 14864AA020.

Hello all, So my LH Combi valve is stuck open and I dont want to replace it. In short my question is, Instead of installing the block off plate for the LH combi valve on the head or in between the pipe and valve, can I just use some high temp epoxy and plug the Inlet on the valve?

Anybody know the Passenger side OEM Plate PN to block off the air pump port in the engine? 2007 STI come with the port blocked on passenger side.

For some reason i dont think KSTech lists the PN on their website. Im not sure if anyone else manufactures them but I recall only seeing the KStech one when I was looking for them.

pst, the bolt spacing is the same and should seal on both sides. That info is in this thread.

Bolt spacing is not the same you have to alter it for passenger side, yes---------I have a drill press but if there is an OEM part that respects the bolt pattern then I will get the one I don't have to modify.

I give up, I will ask the parts guy for the PN.

That PN is for the passenger side they never made one for the driver side but you can drill the passenger side to fit the driver side too.

Nope, there is a driver's side and a passenger side, the one I am looking for is below comes in the 2007 STi, the one you are referring to is from the Tribeca 14754aa050.

There is two different OEM block plates for driver's and passenger's side, I need the PN for the 2007 STi, pictured below.



Therefore, there is no need to do this:
