Have the above car, getting OBD code P0440 Evaporative Emmission Control System Malfunction. No performance problems. Clear code and comes back after several days. Looking for any input on what/where information to locate/fix problem. Gas cap on tight. Thanks

I haven't had this code on our Subaru, but I had a P0455 and P0456 on my Jeep. It turned out to be a loose vacuum hose on the intake manifold.

I would start by looking around the engine and charcoal canister for loose or leaking hoses. I don't know the exact location of things on your model so I can't be more specific. You might also test the purge solenoid.

I can no longer say that we haven't had this code on the Outback.

Yesterday I tested the purge solenoid and it was fine. I guess I need to start looking for leaks elsewhere in the system. :banghead:

bcstorm, did you ever get your problem resolved? If so, what was the cause?
