    Curse you Perry the Platypus!
    Well, got the check engine light and code P0456 (Evaporative Emissions System Small Leak Detected) thrown up. I just put on a new, OEM gas cap so I'm hoping this does the trick but so far the light/code hasn't gone off and I don't feel like undoing the battery yet. Anyone have suggestions on what I can take a look at next before going to a mechanic? I have a 2010 Tundra with 135,000 miles on it. Truck runs and sounds fine.

    Hopefully it will go off after a few cycles.

    Fingers crossed! I might just go ahead and unhook the battery this evening.

    Or maybe go to Autozone or another store and they can reset the light with their code reader.
