http://www.smogtips.com/check-engine-light-turn-on-off.cfm. best bet is to take it to a mechanice so he can use a device called a battery tender. This is plugged into the cigar lighter socket before you disconnect the power and ground cables to not only hold the radio station presets, clock settings but also keep the on-board memory alive for the power-train control module (PCM).

I am having the same issue. Gas cap light comes on and pending code P0455. Changed cannister purge valve, vent valve, has cap, fuel tank pressure sensor. Had a snoke test done, no leaks. Still the light comes on. What else could it possibly be???? I'm at my wits end.
