2003 Subaru Forester 2.5x with a check engine light

Asked by mrfixit69 Mar 23, 2016 at 06:14 PM about the 2003 Subaru Forester X

Question type: Maintenance & Repair

Hey Scotty, got a 2003 Subaru Forester 2.5x with a check engine light. I think
the engine code is 495 gas cap. Tried a generic and than put out $30 on a
OEM. It is pretty consistent throwing the code. Seems to happen more when
I filler up the gas! I have had a few times in between fill ups the error does
not occur. But eventually will happen. Heard the vent canister might be full of
gas?  Please help!

My 03 Forester XS started to have the same problems.I bought the filler cap at the Suburu Dealer. After talking to the parts guy, he asked me if i filled my tank up while the engine was still running. Well i told him i sometimes do....but only when im in a hurry...then he asked if i topped off my fuel tank??? He asked me if i ever took the time to read over my owners manual...i told him no!!! He told me im not the only person to not take the time to read it. He told me to look up filling the tank. Damn me...if u look in that section it plainly says, DO NOT FILL YOUR TANK WHILE ENGINE IS RUNNING OR DO NOT TOP OFF YOUR TANK. It seems your charcoal fuel canisters get flooded with raw fuel. Subarus are very touchy about that.Your check engine light will immediatly come on in both instants. Of course it will cancel the check engine light out its self out. Only after the extra fuel in the canisters are depleated out of the fuel emission system. Take the time to at least look at the manual.
