2005 Subaru WRX Trouble Code List: Please Help!

Hi Guys,

I recently viewed my trouble codes through ecuexplorer.
I've been struggling to find articles/write-ups about these specific codes.
Can anyone help me understand their meaning?
Any help would be greatly appreciated.
Would also like to know, which ones are of greater concern, to the life of my motor.]

Hope to be hearing from you soon.
Thanks.

Which ones are you having trouble with?

I presume that if the errors are visable, that means they all a problem...???
Would like to know how to rectify these error codes... :wink:

Any thoughts?

Are you telling me you have all those error codes stored in your PCM?

Yip...I'm just as surprised as you are...

What now?...Set the car a light?

What happened? And don't say "nothing" because there's no way that laundry list set with no provocation. Were you in an accident? Were you working on the vehicle recently? Be straight.

Bought the car 2nd hand at the beginning of this year.
Almost 2 months down the line, the car went onto a dyno, and detonation could be heard from outside the car.
My fuel map was then made slightly richer, and I started to run higher octane fuel, in order to resolve the det temporarily....that's it... :shock:

I think the car already came with problems...just wondering whether I've left it for too late...only learnt how to check error codes yesterday...

Any constructive advice?

Yeah. Don't screw around with the programming on your engine. They spend millions developing the software and the guys that do it are much smarter than you or I. How did you adjust your air/fuel mixture and not know how to pull codes??? I mean, I don't get it. I don't even know where to start. You've got OSV codes, MAF circuit codes, throttle valve codes and TPS position codes, transmission communication errors, a possible short in the PIVGN circuit as well as supply voltage problems, I mean, I don't even know where to begin. All this time you've just been ignoring the check ngine light? Im sorry but I can't help you. We don't get paid for this and that fix would cost you a fortune because somebody is going to have to wade through all that nonsense to fix it. It won't be fast and it won't be cheap. I have no doubt that it can be fixed, but not on this forum and not by you. Im sorry.

I never changed the AFR's myself...I took the car to a performance center, out of desperation!
I've been driving the car very carefully, from the day I heard the detonation...the car drives fantastic...and what's weird, is that the engine light has never come on.
Started to do some research, and here I am now, capable of extracting engine codes.
What do these codes mean?...What needs to happen in order for them to appear?
I'm soooo bummed!

If there's a detonation, then that needs to be fixed and not by a reprogramming. The vehicle already has a system in place to take care of detonation=knock sensors. When they detect pinging, the change the timing of the cylinder's spark. That protects the engine. Start with the continuous codes and fix those first. Then once those are fixed, tackle the non-continuous. After that tackle the pending codes. It's going to be best for you to take it into the shop. Unless anyone else on this forum has any ideas, and Im guessing they don't because no one's posted since your first post. It would take a month of Sundays to try and diagnose that vehicle over this forum. I don't have that kindof time. Again, Im sorry, but that's the reality. Take it into a good, quality auto repair shop or park it and tinker over time. Either way, you're not gonna be happy.

'Darkrooms'...I'm just grateful that someones responded...

I'm definately going to take the initiative to sort these codes out, but I just wish I could understand each one, and where they coming from...do you have any idea what triggers these codes?

If I previously new that one could do a diagnostics check on the motor...I would have resolved this a long time ago...unfortunately, a learnt these things a bit too late...still shocked that no engine lights were triggered.

Do you think an electronic boost controller, which supersedes the OEM solenoid could cause 'OSV Solenoid Valve' errors?
