    What could be causing CEL code PO244?

    I really hope somebody can give me some insight as to what might be causing my check engine light to pop on. I got a read and its code P0244: " The PCM has determined that the votage signal for wastegate solenoid "A" is out of range for the current engine operating conditions."

    My car is totally stock save for a BOV, which was on when I bought the car. My car is behaving oddly at high RPMs in gears 4 and 5 and when the throttle is really pushed in any gear. I think it has something to do with the turbo. I'm planning a 4k mile roadtrip in the middle of May and I really don't want to drive that far if my car is acting funny but at the same time I don't want to get the run-around from some mechanic.

    If anybody has any ideas as to where I should begin as far as correcting this problem, PLEASE let me know. Thanks.

    r you sure that you dont have a down pipe? make sure you dont, you could be havng wat is called boost creep, r you sure it doesnt do it in third gear too, i believe thats where you run the higest boost. i personally would invest in the cobb accessport, it will tell you the codes, i dont know wat that code is, but myguess the guy might have have performance parts on it before. the reason the car could run like crap at higher rpms could be because your leaning out.

    To be honest, I don't know if I have an aftermarket downpipe. I'm gonna follow up on that. Suppose I do and suppose that I am experiencing boost creep, then what do I need to do to correct the probelm? Is this a problem can can be potenially very harmful to my car?

    Get rid of the BOV and then tell us if you're still having problems.....

    Who protuned your car to support these mods? If the answer is nobody, then there's your problem. You're running several mods that are not recommended so put them together and you have a bad setup, compounded by a lack of tuning.

    You don't have a cat. That right there is a big no no for the STi. I would get a DP with a cat unless you like running into boost issues because there's no way that you can reliably tune for the lack of backpressure from a catless exhaust and the stock turbo.

    There's no need to have the FMIC without a larger turbo. It's adding complexity to an already complex system and providing no benefits. The shorter piping of the stock TMIC is going to work better, plus the stock setup is supplying more than enough air to the turbo so there's no need for a larger IC because your intake charge is not much larger than stock.

    With respect to the 50/50 BOV, how is that set up, i.e. how much is venting to atmosphere? Aftermarket BOVs are notorious for causing problems in Subarus. Hopefully you have it set up 50/50 instead of venting to atmosphere but even then, the stock BPV is going to work better.

    I'm glad to hear that your car was tuned, but I've listed three things above that are not recommended mods for an STi and you've done all three of them together.
