What is the first thing to check when the check engine light comes on?

• Check the gas cap: a loose or damaged cap is a common, simple cause that can trigger the light.
• Look for obvious issues: low oil or coolant, visible leaks, or a disconnected hose under the hood.
• Note vehicle behavior: loss of power, rough idle, or unusual noises help prioritize urgent service.
