the odds are there was a bad reading or glitch signal the computer saw that triggered the check engine light

since the on board computer said no faults at this point the code set is in the history and is not a current code

since its running good i would have a Firestone or a place like that read the code for free and tell you the code number if its something like an evap emissions code set make sure the gas cap is tight and if it is have the codes cleared and if that light comes back on i would have the shop diagnose the code number it is setting

how are you making out ?
