This type of code is usually a sticky purge valve itself. This is located in the left front fenderwell area under the hood, has one wiring connector and 2 purge hoses (rather large hoses, like oversized vacuum hoses) running to it. It also has a symbol on top that says "MOT" and an arrow. You may have noticed this before, it clicks away rather loudly when the engine is warmed up and at op temperature. If you get the engine warmed up and don't notice this valve clicking, then it's probably in need of replacement. Sometimes you can slap this valve a couple times and it will start clicking, another good indication that it's getting lazy and in need of replacement. I've replaced quite a few of them. It's fairly common to have this fail, kind of like the mass air flow sensor, all manufacturers are having problems with this part.
