That indicates an "Evaporative Emission Control System Leak (gross leak)"
accordng to my book.

Could be your gas cap is loose (altho that's supposedly a P0457 but worth
checking first...)...loosen it then tighten it 3 or 4 clicks then see if
the light goes out after a while. If not, it could be a disconnected hose
in the fuel vapor system or maybe a bad gas cap or worse.
