P2443 error code

[1 Lucky Texan]

Got that (and a blinking cruise control light) yesterday morning. Read
and cleared the code last night. This morning all normal.

It is one of the air pump valves sticking. Some folks claim it might
just be from condensation.

I don't like this. Some folks have had warranty claims refused for
fixing this system. There are also 'delete' kits for the hardware -
but you need engine management soft/firmwar to delete the error codes.
I think the ystem is only active for a few minutes to heat up the
catalytic converter during cold starts.

sigh - maybe it won't come back. Supposedly, one side is VERY
difficult to work on. parts are $$$$$ too.

you are correct in your statements except that it will come back on.
One of the valves (i believe the one with the sensors in it) is a PITA
to change. I have seen the motor seize up due to moisture. it is a
poor design.

Not good news.
Do you happen to know if in Texas it is covered under the emissions
warranty? I've read it may vary by State.
Also, are replacement parts designed better?
Is there a TSB on this?

I don't know how the warranty applies: I just work on them.

It gets confusing reading the codes and deciding what valve it is.
Mostly replacing the valves has fixed them; not sure if there is any
design changes. Had one where we replaced the motor and it failed and
was replaced again under warranty again.
No tsb as I know of.

Yeah, just about the time I decided that both sides of the engine were
being called Bank 1, along comes this code that says Bank 2.

thanx for the info!

Yep, my CEL came back on when I left work yesterday. I haven't
actually scanned the DTC but I'm sure my 'friend' has returned.

ugh. Wish we knew if the parts have been redesigned. hate to think
this is just gonna come back in 4 years.

(we) thought that it was more a Oregon thing due to our moisture
levels; but seem to see others from other areas now. So far, no
repaired car has come back. They moved the air motor on later versions
and with the new legacy, I believe it has been removed (turbo under
the engine)
Overall, non of us techs will own a turbo Subaru.The problems we see,
not often but occasionally, make us not want it on our cars. Extra
work removing engine, several shelled turbo's due to oil problems-some
on cars with all oil changes documented at our shop (under 30,000) and
the air valves. Oh, there are fun, but risky.

I don't think I have the screen in the supply to the turbo (mine's an
06) BUT, I dunno about screens going to the AVCS system?

Can you tell me if the 2443 code is on the passenger side or on the
drivers side? That might help me determine if I want to ttry the
replacement myself.

checked the books, 2443 is bank 2 and that is the left bank. this is
the easy valve to change.

THANX!

I think both valves are on the same side, but one of them seems to
involve removal of the intake manifold. Another source also indicated
the offending valve for my 2443 code is the easier one.

I still haven't decided what to do, but am strongly leaning towards
getting the whole Tactrix cable/ECU flash/romraider set-up and just
delete the 14 or so codes associated with the system. Then, in spring,
maybe fix or possibly delete it. I need to pass inspection ath the
first of the year. I never intended to go the 'tuner' route, but that
seems to be the easiest/quickest/cheapest solution.

I'm gonna take another look at that valve and try to find a price for
it.

thanx again - your a great resource for us here!

At present, I have experienced and cleared the code several times. It
DOES appear to be the valve. I have confirmed the pump runs and I have
swapped the 'air cut' relays and the code remains P2443.
I am going to monitor the number of starts/miles before it actually
turns on the MIL. It MAY be possible for me to pass inspection with a
'pending' code. I see no reason not to try. I just need to read the
status to discover if the monitors will complete BEFORE the pending
code sets the light.

I figure, worst thing that happens is, i fail inspection and go back
to Plan B - the ECU re-flash.

Hi All. I am one of the lucky ones that bought a turbo before I read this
post. That said, I have the following error codes: P0410, P0148, P2431,
P2432, P2433, P2344. I have already paid 80.00 to get this info and was
told that it would cost 600.00 in parts and labor for replacement of the
secondary ari combination valve. But he can't guaranteed that this will
fix it. Any suggestions? I like this mechanic but he isn't an authorized
Subaru dealer.

I have a tactrix cable on the way, I downloaded ecuflash and will
download Romraider soon.

I also have a copy of a very helpful post at nasioc that will guide me
to disable the codes associated with this system.

you will probably need to sign in/register to view it. If this ends up
working for me, I will report back. It may be a several days as I will
be busy during the holiday.

fyi

I have a Tactrix cable ordered, hasn't arrived yet. Seems the USPS is
very slow.

I THINK I have all the software downloaded. Some 'definitions'/w'ever
have to be installed. I d'loaded the files but haven't ran any of the
programs yet. Hope I can sort it all out when the time comes.

Well, the first Tactrix shipment was 'lost' so, thye sent out a
replacement. I got it friday and today I downloaded my stock ECU Rom
image, modified it to delete the 15 codes that are associated with the
Secondary Air (air cut) System and re-wrote the new image. So far -
everythings seems OK. I guess I'll know more in a coupla days when the
car has had a few start-cycles and I take it in for inspection.

Passed state inspection just fine. No other issues at all.
