Replace teether oil caps/gasoline caps: Most fuel caps are sealed by turning them until you hear a click. Old, loose gas caps, cracked or malfunctioning may cause your check engine light CEL to light up. If your check engine light comes on, or you smell gasoline or diesel steam, or there is an odor of gasoline or diesel steam around or near the fuel filling cap, and your car is not smoking or making unusual noises, take a minute to check the cap.
