MY CHECK ENGINE LIGHT JUST CAME ON AND STAYS ON. WHAT COULD THIS MEAN? on 1995 Toyota Avalon

THIS PROBLEM HAS HAPPPENED BEFORE ON THIS CAR AND IT USUALLY WAS JUST A SIMPLE ELECTRICAL THING OR SOMETHING ELSE SMALL. THIS CAR IS IMMACULATE AND HAS BEEN MAINTAINED TO THE TEE. BUT WHAT ELSE MIGHT IT MEAN?
