    Title says it all basically. I popped a CEL and lo and behold, my gas cap was not screwed on. Put it on to the click and have since started and run the truck a few times.

    Is there something else I need to do to clear the light?

    How much time has passed? If it's only been a few minutes then I'd let it sit over night. If it's still not clear, disconnect the battery to reset everything. Then if it comes back you know it's for more than the loose cap.

    Yeah it's been a few hours. At this point I'll wait until morning and try again. Good idea about the battery, I didn't think of that.

    If it doesn't clear on its own, stop in at a Napa, OReillys, Autozone, etc... and just ask to use their CEL reader, plug it in and clear the code if you don't have one!

    My Tacoma cleared itself after a few days of steady driving.

    Update:

    Went a few days and several hours of driving. The light did not go out on its own.

    So I bought a BlueDriver Bluetooth scan and reset tool. The following codes came up:
    P0441 EVAP System Incorrect Purge Flow
    P0455 Evaporative Emission Control System Leak Detected (Gross Leak)

    I assume those are the correct codes that should pop up due to a loose gas cap? Well anyway, I used the reset function of the BlueDriver. The CEL is off and has not come back.
