Probably comes on for a reason, but nothing of grave importance. Left the gas cap loose once?

It could even be an exhaust sensor sending an error code. If it's intermittent and your car is running just fine and you've checked all the minor stuff (fluid levels, loose belts, etc.) it may just be a sensor. It IS a 2003, so it's got a few miles on it I take it.

with the newer cars if you don't have your gas cap on tight it will throw the engine light on.
