A check engine light that remains on can be caused by various issues, including a faulty oxygen sensor, a loose or damaged gas cap, or problems with the engine's emissions system. It may also indicate issues with the ignition system, fuel system, or even the vehicle's onboard diagnostics. If the light stays on, it's advisable to have the vehicle diagnosed using an OBD-II scanner to identify the specific problem. Ignoring the light can lead to more serious engine issues over time.
