The service engine light can stay on for several reasons, including issues like a faulty oxygen sensor, loose gas cap, or more serious engine problems. It is designed to alert you to potential issues that could affect your vehicle's performance or emissions. To identify the exact cause, it’s best to use an OBD-II scanner to read the trouble codes or consult a mechanic for a thorough diagnosis. Ignoring the light can lead to more significant problems down the road.
