    Default Cel code P0447 - ideas on solutions?

    Hi all:

    My 2002 Subaru Legacy wagon is throwing out a "Check Engine light" and the
    code of P0447. We have tried a new gas cap and that hasn't solved the
    problem. Any suggestions on what else might make this happen?

    Thanks!
    Fred

    My car is a 1999, a bit older than yours. But it had a corroded
    filler tube at the gas tank after 7 years.. The replacement cost
    $500!

    Fred,

    A P0447 code means a leak in the pressured fuel system. I cleared the
    code out from my 1998 Subaru GL wagon a couple of times, but the check
    engine light kept coming back indicating the same problem. Because the
    diagnosis required specialized diagnosis equipment that my regular
    mechanic did not have, I had to take the car to my Subaru dealer to have
    the fuel system smoked out. In my case, the problem was a leaking fuel
    filler pipe and vent valve ($570). Diagnosing the problem without the
    proper tools is very time consuming and liable to miss the problem, so
    taking it my dealer (at thrice the price) was my only option.

    Hope this helps,

    Thornton

    If it WERE due to a loose gas cap - after correcting, it may take a few
    start/drive cycles to turn out the CEL - actually, any intermittent
    wiring/sensor (such as a 'lazy' O2 sensor) might cause that effect.
    We once owned a '96 Ford van that would turn its CEL on with an altitude
    chnage of only a few hundred feet - after 2-3 days the light would go
    off, only to return again after we drove back home.

    Well, we tried a new gas cap, and that didn't fix the problem. So, we
    put the old one back. It could be some sort of wiring issue... in any
    case, I am just glad to ignore it for now and not have to spend any
    more money!

    Too bad these CEL things aren't more reliable...
