2011 Hyundai Accent Check Engine Light Codes

At Larry H. Miller Hyundai Peoria in Peoria, AZ we routinely diagnose the most common codes that set off a check engine light on a 2011 Hyundai Accent. Typical trouble codes include P0420 (catalytic converter efficiency), P0300 (engine misfire), P0135 (oxygen sensor heater circuit), and P0442 (evaporative emissions leak). Ignoring these codes can escalate costs: a loose gas cap or EVAP leak may cost under $150 if addressed promptly, while unattended misfires can damage the catalytic converter and lead to repairs exceeding $1,000. A failing oxygen sensor left unchecked reduces fuel economy and increases emissions—costing you at the pump over time. Our certified Hyundai technicians use OEM diagnostic tools to identify the precise code and propose a targeted repair plan, ensuring you pay only for what’s necessary. By choosing our dealership you gain transparency, factory-trained expertise, and warranty protection—delivering both immediate repair savings and long-term ownership value. To move forward, schedule service online or review our current service specials for bundled savings.

2011 Hyundai Accent Check Engine Light Reset

Resetting the check engine light on a 2011 Hyundai Accent may seem simple—clearing codes with a scanner—but a reset without diagnosis can hide symptoms and let an underlying problem worsen.

This approach prevents repeat visits and saves money over time by avoiding temporary fixes that create bigger problems later.
