Have you had it scanned?If not and you are in the usa,you can get autozone to scan it for free,to let you know why it is on.If car run,s same no overheating ,and power,s the same ,it is more than likely a 02 sensor,have you tried to reset it, by removing your positive cable ,if so and it come,s back on,go have it checked,,,good luck with it.
