Ok. I am still chasing this problem down.

I have an appt on Friday to get this checked out, but if I can narrow it down myself I would feel better.

Had the code read last week at a shop. THey just said that it was an emissions code.

Went to autozone yesterday. They pulled P2443

I have searched and only found something about "air pump bank valve B" or something like that. Any ideas?

Maybe it was bank 2....which is bank 2? Driver's or passenger's?

Update:




Now I am really angry. The problem is with the secondary air pump valve. The part is on backorder, and when it gets back in stock it will cost almost $300.00. The shop also quoted almost $600.00 in labor. How sad, I really like this car, but having to fork out almost a grand to have a $25k car fixed after only 39k miles is a real kick in the nuts. I called SOA they said to take it to the dealer and get a claim started so I guess that is good.... The whole thing still pisses me off though.

I just threw the same code. Mine says it was stuck closed? Does anyone have any idea what that means and any long term impact to the engine? Does it my by A/F ratio's are off because its not getting air in the cylinders?

Just got the same code too. Cleared it with AP, and hasnt come back yet - going for a drive to see if it comes back. I am pretty sure that this is just the valve that feeds air into the exhaust during warm up (to heat the cat faster) and wont do any harm. I could be wrong tho.

AP said valve was stuck.

Took mine into the dealer, said there was a stuck switch. Wasn't a problem at all but with the SI drive CEL prevent switching between S# and S, which was more of a nucense.

I just got back from a second check on this - they replaced a relay, no fix, now they tell me the ECU is not sending a signal to open the valve.. they replaced the relay under warranty, but i was honest about my cobb reflash, so i dont know if they will honour the warranty for the ECU

ECU is ordered, but i will have to reflash in the subaru shop. Ouch. wish me luck.

I had this issue as well...

I just got my car back.

Lithia Subaru in Oregon City, OR.

The shop had my car for a week, so I drove their 2009 forester loaner which was a really nice update to that model, but gutless as all hell.

They ended up replacing the relay, which did not fix the issue.

They ordered an ECU from the factory which did not fix the issue as well.

Finally they tore off my intake manifold and fixed the valve which was indeed stuck closed. They also replaced the intake manifold gasket and I haven't had a CEL yet. I have only driven it once since I picked it up, but before they worked on the car the CEL would come back after a clear within the same day.

Just thought I would let you know what they did.

Here is a copy of what was on my invoice...

1 25232AA090 RELAY
1 FREIGHT AND SHIPPING
1 14864AA030 VALVE AIR SUCTION
2 14025AA421 GASKET INTAKE MANIFOLD

31955 CODE P2443 CHECKED ALL ELE STEPS FROM 1 TO 13 FOR EN H4DOTC DIAG 372 ALL CHECKED OK CALLED TECK LINE WAS TOLD TO REPLACE VALVE AS B ON BANK 2 CASE NO ********* HAD TO REMOVE INTAKE TO GET TO VALVE

The ECU shipping took like 2-3 days, otherwise this fix would have been done within 48 hours.

Just thought I would let you know what happened with my ride.

I pulled the same code P2443 "secondary air valve stuck closed". Had the valved replaced under warranty. Can anyone explain what this system does? or confirm this:

Unhappy

I've been fighting with this f'ing code over the past couple weeks (p2443). The dealer checked it out and came back with secondary valve(driver's side, bank b, not the one under the intake) stuck closed. Apparently water gets in it at which point it gets messed up. The dealer said it would need replaced and that the PCM system would need to be recalibrated, of which they would gladly do for $470. Sooo...Could I just take the valve off, clean it out and kill the CEL?

That would be quite a bit of work. IMO, just get them to do it. Are you out of warranty? I was stage 3 at the time, but bc I had not touched the emissions system, they honored the warranty, and just changed out the valve.

sammae, I dont think it will hurt anything, just that you wont know if you have another CEL go off if this one is constantly on. you can reset with a Cobb AP, but it will come back after 5 starts if I remember correctly. I am super anal when it comes to any issues with my car, so I would get it fixed. Really, I dont think it will hurt anything, but I am no expert.

Oh Crap it's him, Did you end up fixing this problem? This has been happening to me and I'm going to try to repair it myself this weekend as the dealer wants way too much for the repair. Any help would be appreciated.

I got P2443 and took it to the dealer. They said water got into the air pump (possibly just environmental moisture + short trips) then corroded the valves.

So they want to replace both switching valves and the air pump assembly.
diagnostic $80
parts $1308
labor $495

i feel everyone's pain. i am having similar issues with my 2006 WRX and it happens to be out of warranty so i'm stuck with having to come up with a lot of cash.

i already paid $870 to replace the secondary air pump, which was fried due to water in it. after the pump was replaced, check engine light came back on and they thought it was just a relay, so they got a new relay. check engine light came back on again that afternoon. they've been testing it all week and just called me to tell me that both of the suction valves associated with the pump need to be replaced, and parts/labor will be about $1400.

this is just absurd. i've talked to SOA, because i had a stuck valve problem right after i bought the car, about 1500 miles on the odometer. took them a month to fix and SOA extended my warranty to 100k. too bad all this crap started happening shortly after i passed that threshold.

think i need to take a trip to the bank and see about a loan still owe about two years payments on the bastard too.

I have seen threads about people removing the air pump altogether. Would doing that solve this problem? Is removing it more expensive than repairing it?

I just got this code as well. It's been popping up over the last few weeks. If you have it and you're out of warranty (I'm not sure if I am since I'm at 56,000 and I understand anything with emissions should be covered) you can try this: let the car warm up to normal operating temperature before you drive it. All the valve does is get air to the cat to heat it up quickly. If you don't mind waiting for the car--and therefore the cat--to heat up on their own, then the valve being stuck shouldn't be a huge problem. I was super worried about the code because I'm heading on a short road trip tomorrow, but now I'm pretty confident that I won't hurt the car if I let it warm up. Let's just hope SOA will honor my warranty and fix this problem, because I simply dont' have $1,000 to drop on this nonsense (that's a decent set of wheels, after all).

Same thing happened to me this morning. I called the service department at Austin Subaru and told them that I had my code scanned at Auto Zone and that it was the p2443 secondary air valve whatever. . . the guy asked me if I had it reset (which comes into play in a second) and then he told me that sometimes the ECU will kick out a CEL inadvertently if the system isn't ready for the check. I don't know why that would be an issue but then again I'm not a mechanic. Anywho, when I got home I disconnected the negative battery lead and let it sit for a while, reconnected it and started up the car and let it run for a while. I shut it off for a few minutes, came back and started it up again. No CEL. I know the ECU has to have some time to reset its parameters after a reset like that so I will repost my findings tonight when I get off work, and again if the CEL comes back. Just thought I'd throw it out there in case it helps someone else.

I had the same issue with my 06. Happend to me at 36K miles.

Bought a Tactrix cable, deleted that code permanently, problem solved. Im at 96K now and still no issues.

Well, this is probably no surprise, but my CEL came back after 15 miles. Looks like I'll be dealing with the service department on Monday... Wish me luck! I will repost with my experiences.

If you open your hood and look directly behind your battery (towards the firewall) that turbo shaped pump is bad. They need to replace it $934 dealer cost, hopefully your warranty is still good. Otherwise do what I did and buy a tactrix cable and follow the tutorials that are found in the ecu modding section.
