What does it mean when the check engine light comes on in a 2014 Hyundai Sonata Hybrid?

• The light indicates the vehicle’s onboard computer has logged a fault code; severity ranges from minor emissions issues to engine/system malfunctions.
• Codes point to systems—EVAP, oxygen sensors, ignition, fuel system, catalytic converter—so a scan identifies the subsystem needing attention.
• An illuminated steady light usually means non-urgent service is required; a flashing light signals a potentially severe condition that needs immediate inspection.
• Prompt dealership diagnosis prevents escalation, preserves warranty eligibility, and often saves money by fixing the root cause correctly the first time.
