Take the car to a local parts store (AutoZone, Napa, Advanced Auto Parts) and they have hand help computers to read the error code and let you know what needs to be fixed.  They do this for free in my area so I assume it would be the same for you.  Obviously you can also take it to a mechanic to have them read it for you but that will normally cost you.  If you get the error code and need help with that, repost and I will try to help you out.

    Here is what I could find on the P0455:

    After market parts and accessories nonconforming to the EVAP system specifications.
    Damaged, missing or improperly installed fuel filler cap.
    Blockage in fuel vapor hoses/tubes (EVAP canister tube, EVAP canister purge outlet tube or EVAP return tube) in EVAP system.
    Disconnected or cracked fuel vapor hoses/tubes in EVAP system.
    EVAP canister purge valve stuck closed.
    Canister vent (CV) solenoid stuck open.
    Fuel tank pressure (FTP) sensor malfunction.
    EVAP canister leaking.
    Fuel vapor control valve tube assembly blocked.
    Fuel vapor vent valve assembly blocked.

    Obviously the easiest thing to look at is the gas cap and make sure that it is on correctly and tight.  After that I would consider any of these other options non-DIY and you would more than likely have to take it to a mechanic to have additional tests done to see what is causing the system link.  Sorry I know that is probably not what you want to hear, but hopefully it is just the gas cap and you can fix it yourself for free!  Hope this helps.

Keithheavili has the right solution... but if your check engine light is blinking on an MPV... STOP DRIVING!!!! blinking indicates engine misfire leaking fuel into cats. you will ruin your cats. they cost $2500 parts alone!
