The Check Engine Light can be triggered by various issues, ranging from a loose gas cap to serious engine components malfunctions. The best first step is to check the gas cap, as it is a common cause. If the cap is secure, it’s wise to have an OBD-II Scanner run diagnostics on your car. This will help pinpoint the specific engine repair needed. A professional mechanic can then determine whether it’s something simple, like a faulty spark plug, or more serious, like a fuel system issue or engine damage.
