Engine light come on
I had the same problem.I took mine to the Honda dealer. They said that the gas cap was not fully close.
The gas cap is possible. If you have it scanned for codes, that would let you know. You probably would have a po442 code.
I could be wrong about the answer but this happened to me once. If it isn't the gas cap, when was the last time you had your oil changed? If you oil was changed, did they reset the maintenance light, even if it wasn't on when the oil was changed? Have somebody scan your system but only if your maintenance light is ON.
