Use a code reader to check the engine diagnostic code using an OBDII code reader. If it's the gas cap you may need to replace the cap then reset the diagnostic codes by following the method described in the owners manual.

A code P0455 is a Gross Evaporative Emissions System leak code. There are way to many options to list them all for this problem, however the most common is a line on the Evaporative Emissions Canister being broken off or disconnected. That is where I would start. Good Luck!
