P0441 code on my 07 WRX, WHY?
P0441- Evaporative Emissision incorrect purge flow
What does this mean? Where could the problem be? anyone else had this? My 06 service manual doesn't even list it, only a P0442 and up. I checked the gas cap by the way, it's not that.
Did a walbro fuel pump install and tgv deletes where I took off my intake manifold. Everything else works, no boost leaks anywhere. Got it tuned. Everything is good, except when just cruising I randomly throw this code.
I also can't find, for the life of me, the evap purge solenoid. Any help on locating this would be great to.
TIA

The evap has to do with the charcoal canister in the back of the car. There are a couple of valves involved with this thing. The one i'm thinking it could be, since you took off the manifold, is the one that hooks on the front of the intake manifold. There is a little valve right in the vicinity where the turbo inlet goes from the front of the engine - under the manifold - to the turbo. if your standing in front of the car you should see the valve on the left side of the motor right by the turbo inlet, front part of the intake manifold.
Otherwise you gonna be at the meet on Saturday in Turlock? I should be there if i remember, lol. i can show you then or look at it then. All the hoses for that valve are confusing to try and explain in text.

Hmmm...threw the code again today while cruising to school. Been driving for about 20min before it came on. Outside temp was 29* and I was cruising in fifth around 50mph...similar to the last time I threw it. It only seems to come on when cruising in fifth.

It would have either been from the intake manifold removal or related to the charcoal box in the back. I think when I got tuned and they took off my tow hook they accidentally jiggled one of the canister hoses. I put jiggled them back a little and it hasn't come on since. I'll update if it does happen again though.

I have been having the same problem with my car. For the past 8 months...the stupid code is annoying. It also came on after I put in new pe 850cc injectors, I just ordered a new purge solenoid so I'll keep u posted if that cures it...and I also changed the gasket on the fuel tank like my tuner told me and it didn't work...

After verifying that there are no leaks between the fuel tank and intake manifold, connect the green test connectors, turn the car on/run, and make sure all of he components are making noise.
If they all work, it is most likely the two valves on top of the fuel tank.

evap purge valve is the culprit. It's sending that noise directly into the inlet tube. When I pull the hose between the inlet and the valve off the sound resonates out of it very strongly. My guess is that the solenoid is stuck.
How much does a new one roughly cost?
Can the valve be repaired?
