If the check engine light is on in your 2003 Ford Focus but everything seems normal, it could be due to a minor issue such as a loose gas cap or an emissions-related problem. It's advisable to check the gas cap first; if it's secure, consider having the vehicle's diagnostic codes read at an auto parts store or mechanic. Ignoring the light could lead to bigger issues down the line, so addressing it promptly is wise.
