    I don't remember which code number it was, but it was the one that comes on when you don't turn the gas cap until it clicks after filling with gas. I must've gotten distracted.

    The person at O'Reilly's that helped me said that the light would go off after a day or so.

    It has been 3 days and I'm wondering if I need to have the code cleared.

    I'm guessing they aren't allowed to clear codes at O'Reilly's.

    Thanks.

    I once bought a defective new “oem” cap from eBay and it didn’t work. I then bought aftermarket from Orielly’s. Light turned off on its own. When you correct the condition the light should go off - depending on the condition. Easy to clear with a cheap $20 reader from the inter webs.

    You can also try disconnecting negative battery terminal for an hour or so

    Depends on if it's a pending or history code.

    I don’t believe the light will come on if it’s pending. But maybe it does. I think it could take a few cycles to clear for the more in depth issues that require several cycles. But I usually clear them with scanner.

    Spend $35 and get a code reader to read the code, then post it here. The $35 code reader should also be able to clear codes.

    This. You can buy them at walmart and Amazon. No excuse really 25 years after OBD2 became standard to not have a $35 code reader and still be posting threads asking other people what your check engine light is for. We cant really help you with the information provided.

    Depending on your driving it can take longer than 3 days to clear a fault code assuming you have repaired the fault condition. As others have said you can disconnect the battery to clear it.

    When it happened to me, the gas station was so noisy combined with my trashed hearing, I couldn't hear the click. Third day, it was gone. Still seeing "drivers" filling up with engine running too.o_O

    When my wife is on board I have to keep the engine running occasionally as she is on her air machine and it's charging. Easier to fill with it running than hear some gawd awful noise from the passenger seat. :argue:

    Just sent for a new gas cap since it's so cheap. Thanks everyone for all of your input.

    I ordered a scanner, but before it arrived the light went out on its own...of course it did.
    It took about 4-5 days of intermittent short trip driving and it finally went out.
