The Check Engine Light (CEL) on a car's dashboard is a warning sign from the vehicle's onboard diagnostics system (OBD-II) indicating a possible issue with the engine or related components. Reasons for the CEL to illuminate can vary widely from minor issues such as a loose gas cap, which might be quickly fixed, to more serious problems including engine misfires, faulty oxygen sensors, or emission control malfunctions. When the light comes on, it's advisable to use a diagnostic scan tool to retrieve the specific error codes from the OBD-II system, which can provide insight into the nature of the problem. Ignoring the CEL can lead to more severe issues, resulting in higher repair costs and potentially endangering vehicle safety. Therefore, it's recommended to address the issue promptly, either by inspecting common culprits yourself or taking the car to a professional mechanic for a thorough examination and repair.
