Check engine light won't go out?

If your check engine light won't go out, it may indicate an ongoing issue with your vehicle that needs attention. Start by checking for any obvious problems, such as loose gas caps or fluid leaks. If there are no visible issues, consider using an OBD-II scanner to retrieve the diagnostic trouble codes, which can help identify the specific problem. If you're unsure or the issue persists, it's best to consult a mechanic for a thorough inspection.
