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...
