Frequently Asked Questions

What is the most common reason for check engine light on a 2016 Hyundai Accent?

• Loose or damaged gas cap is the single most common cause — it can trigger an EVAP system code and is inexpensive to fix.
• Faulty oxygen (O2) sensors, MAF sensors, or ignition components (spark plugs/coils) are frequent culprits and affect fuel economy and emissions.
• Ignoring codes can lead to higher repair costs over time — a bad O2 sensor or MAF left unchecked can damage a catalytic converter, which is far costlier to replace.
• At Courtesy Hyundai of Tampa, factory-trained technicians diagnose the root cause quickly, helping you save immediately and over the life of the vehicle.
• Warranty-covered repairs must be performed at a certified dealership to remain valid.

What does it mean when the check engine light comes on in a 2016 Hyundai Accent?

• The vehicle’s computer has detected a fault in the emissions, engine, or drivetrain systems and stored a diagnostic trouble code (DTC).
• The light can indicate anything from a minor emissions issue to a more serious engine or fuel-delivery fault; severity varies by code and symptoms.
• A proper scan at our dealership reads stored codes and live data to pinpoint the issue, rather than guessing.
• Using Courtesy Hyundai of Tampa delivers precise diagnostics from factory-trained technicians, with genuine parts and warranty protection.
• Repairs covered under warranty must be completed at a certified dealership to maintain coverage and ensure long-term savings.

What is the first thing to check when the check engine light comes on?

• Check that the gas cap is tight and undamaged — a loose cap can trigger an EVAP code and is an easy first fix.
• Look for obvious signs: low fluids, unusual smells, or recent fuel or service changes that might cause a sensor alert.
• If the light persists, schedule a diagnostic scan; our technicians will read codes and evaluate real-time data to avoid unnecessary parts replacement.
• Using our dealership ensures any warranty-related work is correctly performed and documented by factory-trained staff.
