Check Engine Light Reset

The check engine light reset process for a 2014 Hyundai Sonata Hybrid begins with a full, technician-led diagnostic rather than simply clearing codes. Resetting the light without repairing the underlying cause can mask problems that reduce fuel economy or damage components over time. At Coggin Deland Hyundai in Deland, FL, our certified technicians use OEM-grade scanners and manufacturer procedures so resets are performed only after confirming the issue is resolved. This ensures long-term reliability and preserves warranty eligibility — repairs covered under warranty must be performed at a certified dealership. We document every step, provide a clear estimate, and show you real-time results so you understand the repair and the value delivered. If a battery-related issue is identified, we’ll test both the 12V system and hybrid system where applicable and recommend OEM replacement parts when needed. To protect your Sonata Hybrid and maximize resale value, trust dealer transparency and schedule service through our convenient online tool — schedule service. Check our service specials for current savings and ask about service financing to get repairs done now and pay later.

2014 Hyundai Sonata Hybrid Check Engine Light Codes

Common diagnostic codes for a 2014 Hyundai Sonata Hybrid seen at Coggin Deland Hyundai include EVAP leak codes (often caused by a loose fuel cap or faulty purge valve), oxygen sensor and catalytic converter efficiency codes (which affect emissions and fuel economy), and misfire codes that can be caused by ignition or fuel delivery issues. Hybrid-specific codes can also indicate battery charging or inverter concerns, which warrant dealer-level testing. Left unaddressed, these faults can lower MPG, fail emissions tests, and escalate into costly repairs such as catalytic converter replacement or extensive engine work. At our Deland, FL service center we prioritize accurate diagnosis with factory tools, explain repair options in plain terms, and present OEM parts as the best long-term value. Our team focuses on quick turnaround, transparent pricing, and long-term maintenance plans that reduce ownership costs.
