Default Help: deleting air pump system

So my wifes 2009 wrx265 wagon threw a CEL last week. It was one for the P2444 secondary air injection system pump stuck on. I did some searching and found many threads about deleting the air pump system. I have got the drivers side valve out, air pump, and some of the hoses.

How do I get to the passenger side valve/pipe that goes to the head? I can see it but its a PITA to get to. I have read that some members have puller the intake manifold or up pipe+downpipe+passenger side exhaust manifold.

I have bought a COBB AP to delete the CEL's as I have read in many other posts.

Has anyone found an easier way than removing the above mentioned stuff? ANy help would be greatly appreciated (currently frustrated in the garage).

Unless the RHS (Pass) valve is stuck open-

Unplug the valve.
Delete/deactivate CEL.
Live a happy life.

Without power (assuming the valve isn't stuck open), the valve will remained closed. I ran this way for 4 years with no problem, and have sorted CEL/air-pump issues on other cars in this manner, which have also been fine for years.

Really, the only way to remove the X-over pipe with relative ease (and I use that term loosely) is with manifold and turbo off (which is what I did recently during upgrades), and even then the swear jar made some money.

I hope the valve isnt stuck open since I dont think I am going to take everything apart to remove the valve and block off the head

Thanks for the reply. Now its time to put it all back together, install the CAI and AP.

you MUST research this one as they changed the air pump system several times and you can do the wrong things here really easily if you follow the directions for the wrong system

beware!!!

^Completely agree.

One thing I did forget is the difference between here in AUDM-land and over there in the US.
For us Australians, an atmo pressure sensor was never incorporated into the valve assembly for 06-07 like it was over in the US, which makes the above method an easy and viable option.
Definitely something to check out.

I used an air powered hand saw from blue point and cut the pipe in half so I didn't have to take turbo and 8 millions parts apart. I can look I see if I have some pictures...it's the not the most fun DIY for sure...

from what I have read the passenger side has an atmospheric pressure sensor incorporated in it. This sensor needs to be left in or the car wont start since the ecu compares the atmospheric pressure to the intake manifold pressure. (please anyone step in if Im wrong)

I wont be removing the passenger side sensor since its so hard to get to. What I plan on doing is pulling the relay to this passenger side valve so it never opens and deleting all CEL codes associated with the air pump system. Also, I have already removed the air pump and driver side valve and installed the block off plate on the driver side

The car has seen a couple of Km's the last week and no issue yet with the removal of the air pump system. To recap: air pump removed, driver side valve removed and block off plate installed, pulled all fuses for air pump system (3 relays and 2 fuses? I cant remember).

The car does take an extra second of turning over before it starts in the cold (-10 deg celcius). Other than that seems to be OK so far.

QUESTION: If I pulled the fuses and relays to the pump and valves is the atmospheric pressure sensor on the passenger side valve still getting voltage to work properly and send that info to the ECU? the passenger side valve is still in place and connected to the wiring harness. I cant get to the wiring harness plug for the passenger side valve to check voltage since its buried under the intake manifold. Anyone know if this might be an issue?

Installed the Cobb SF+ intake and stage 1 map for the intake. Deleted the CEL codes. Now I am overboosting in third gear. I have read a lot on this forum and will try the LWG map for the winter months (its -15 deg celcius right now) and do some data logging.

Is there a fuse for the air pump that we can just remove to turn it off?
