I've had this before. But I didconnect the battery for 10 mins. to reset and boom. Went away and didn't never come back. Not saying that will work in your case.

 

If you just filled your tank and didn't put the cap on right it will come on. I've had it come on twice after filling up the tank and it goes off after a certain amount of restarts without a code..

I actually think the last time tricked it by turning it off and on 10 times quick.
