Part goes for about 250.00 Not too bad to replace. It sits under your IC on the drivers side closest to firewall. instructions easy to find. However, the biggest pain is getting the metal gasket to keep still while you line up the bolts. you need to get new gasket with it. about 5.00 You don't want hot exahust leaking into engine bay in this area. lots of wires and sensors to fry. The main killer of this valve is RUST. If you do lots of short trips or she sits out in humid conditions then they die young. Good luck and man don't dealers roll you.

Well I have a short commute and I'm in Florida near the coast so we can check humidity off as well. If I'm feeling wrenchy, maybe I'll give it a go. :-)

Dealt with these when I worked for a Subaru dealer and now see quite a few Tundra's with them going bad to the point Toyota is extending the warranty to 10/150k.

Just got the code yesterday(P2443- Stuck closed). If I use AccessTuner Race to delete the code, will that allow me to still pass inspection if they are only hooking up the computer to the car?

Had the same problem last year. Took it to a tuner to get it deleted and still passed inspection. I live in NJ though so emissions are not as tough as Cali. Car still runs fine and CEL never came back. Cost me 60 bucks! Booyah!

Default Check Engine Light Code 2442

I have been reading this thread and others like it for almost 3 hours. My check engine light and blinking cruise light came on for the second time in a week. I tried erasing it with the computer from O'Reily's but it came back on after a couple of days. The computer said it was a P2442, which I have read nothing about in any thread. Everyone is quoting a P2443 code. I'm assuming these codes are very similar?

The computer said it was "bank 2". As I understand it there are 2 of these valves in the engine compartment.
First question: which valve is bank 1 and which is bank 2?
Second question: is there a video or diagram out there that shows where these parts are located and how to replace them?

Thanks!

I just got this code several days ago. NAPA read the code and reset it. Hasn't come back yet,but I'm sure it will.Mine is stuck closed. Can I get a local tuner to delete it, even if I'm stock and not running any kind of custom tune?

Thanks

Update: I deleted the code using a Tactrix Cable and have been enjoying cruise control for 40k miles. To any who get this code, there is easy relief! Hopefully nobody ever gets this code again.

I got couple codes at the same time and they are P2440, 2441, 2442, and 2443 plus the canister one (i forgot what code is it). I tried to reset them and won't work. I needed to get those codes gone to pass CA smog. That cost me $ 3300 in Subaru dealership to fix everything (two valves, the canister, and also changed my ECU because there was still problem afterward). My subie was at 93k mileage. No warranty.

So i have a question a general question after clearing the P2443 code. I am scheduled for CA emissions test in about 3 months, after clearing the code with the Tactrix cable is there anything else i would need to do in order to get the car ready for the emissions test?

After using the Tractrix, I passed inspection in PA without any problems. You could double-check it with a regular diagnostics cable to verify that no codes are pending.

I have this P2443 code as well and I tried to disconnect my battery and was able to go 75 miles before the CEL popped back up. How long does it take for the monitors to finish checking? Am I able to time this correctly and wait say 60 miles and get my car inspected for emissions before the code pops up again?

I've gone through this thread and have not seen any clear answers on whats the best option if my car is out of warranty (107K) to be exact.

1. Disconnecting battery only lasts so long

2. Replacing the system seems very costly for doing nothing much for the car and the fact that this issue may come up again in a couple years.

3. I read about block off plates, but those alone wont fix the issue correct? You would still need to delete the codes somehow.

4. Using some sort of cable and software to delete like 14 or 15 codes? Is this possible to do to emissions codes? I thought stuff that had to do with emissions could not just be simply deleted?

Not sure what is the best way to go with this P2443 code since I am out or warranty.

Dan, start at about post 36 or so ITT and you can read a little about the codes.

ultimately, you will be best served if you, or some other person/tuner local to you, just pulls the fuses and relay and kills the codes (if the valves are stuck closed).

A lot of you bring up using a Tactrix cable and deleting the codes but won't this be an issue when going for emissions and a monitor would be missing? I think here in CT they check for 10 monitors to pass emissions and If I delete this code wont I only have 9 monitors? If so is that still enough to pass in CT?

I have had this issue with my 2008 Forester XT sport, I replaced the valve under the manifold, which I actually opted to do without removing the manifold, it was not easy but I managed. My code came back, I have found that cycling the ignition a couple of times will stop the code/CEL I also inspected the second air valve but it looked like new, I have been very busy the last few months so I have not had time to work on it. I will post any info that I find regarding my Air control valves. At this time I suspect the relay, however this is no better than a guess based on the fact I can cycle the ignition a couple of times before I crank the engine and prevent the code, if I do not, CEL comes up after second cold start!

Hey everyone, my first post on here. I recently bought a 2011 STi , and found out mine was plagued with this same code. Bought it with an extended warranty so Subaru footed the bill for this one, thank goodness. Valves had been replaced, relays were replaced, and fuses were good. Replaced ECM twice and still the code came back. I eventually took it to my local subaru dealer, I bought it from an out of state dealer, and they finally figured it out. The previous owner drove it for about a year with it throwing the code. So what that did was carbon had built up on the port where the valve attaches to. The mechanic even showed me the air flow chart on their diagnostic software. Cleaned out the carbon, and I've been CEL free!!! I know it worked for sure because previously the CEL would come back on within the day it was cleared, and it has been almost a week now. Anyone else having this issue should try this fix. I'm just so happy that I can drive my car without any problems. I hope this helps.

My experience. Just bought a used 2011 sti a couple weeks ago with the code active. dealer had part on order as i bought the car. brought it in. They replaced the valve. Quite the job. a solid 2 hours of a tech neck deep in the engine bay. Code was gone. Got to finally play with some of the settings. Bam, 3 days later, check engine light comes on. Get code scanned. Same thing. Wondering if the above mentioned carbon issue may be plaguing it. Yay for time left on manu warranty and extended warranty I picked up.

Yeah man I would mention to your mechanic about the carbon build up. Everything on mine was changed twice, valves and ECM. It wasn't a ton of build up, but enough to throw the code. Sometimes its the small things that get overlooked. Good luck and let us know how it goes.

I ended up clearing the code to see if it was a fluke or something after the fix. It came back after 11 days (just yesterday). Now im gonna take it back to the dealer along with the info you provided to see if they can find the cure

For me it got to the point where I was clearing the code everyday, even twice a day at times. I drive 50 highway miles everyday and needed the cruise control, thats why I was clearing it so often. Even SOA couldn't figure it out, they kept recommending a new ECM which wasn't the case. The dealer that fixed mine is Gurley Leep Subaru in Mishawaka, IN, just outside of South Bend. I'm sure they would be more than happy to help with any info your mechanic may need.

I seem to have bad luck with WRX after I pay them off. My 04 wrx broke a piston rod doing 85 on the highway a month after it was paid off (but it had 160,000 miles)

Now I've had an 07wrx for 3 years, havent hit 60,000 miles yet and paid it off in 01/2014 to end up with what could be anywhere from a $160 tactrix cable and some tweaking or up to $3,000 from the dealer due to this cel that has plagued everyone here.

Part of me just wants to kill the code with a tactrix and drive it till something happens. My wife on the other hand thinks I should sell it...which I won't let happen because that's what she made me do with the 04.

I would bring up the issue with subaru of america and see what they can do since obviously your warranty has ended. Many people had problems with the valve system itself. People who waited a while to fix it didnt realize that carbon can build up causing it to malfunction again, which is what happened to me. Ever Since they cleaned the carbon from where the valve attaches to the head, I haven't had any more problems. I believe there is a post on deleting the whole system, but it seems like quite a job

Now that I know more about it cleaning it won't be hard for my buddy tondo.

I got my tactrix cable yesterday and dumped my rom and it took about 15 seconds to disable cel p2443. Also found a stage 1 map to flash
