2013 Ford Fiesta Check Engine Light Reset

Resetting the check engine light on a 2013 Ford Fiesta can be quick, but a reset without fixing the underlying problem only masks symptoms. Our team at Larry H. Miller Ford Lakewood in Lakewood, CO recommends a full diagnostic before any reset. Certified technicians use OEM diagnostic tools to read freeze-frame data and live sensor values so the true fault is identified — whether it’s an O2 sensor, EVAP leak, or ignition issue. We then present repair options with transparent pricing and the benefits of using Ford OEM parts: correct fit, verified performance, and preserved warranties. For owners who want convenience, we offer service financing to handle immediate repairs and flexible payment options. After repairs we can reset codes and perform road tests to confirm the issue is resolved and the check engine light stays off. Protect your vehicle’s longevity and resale value by choosing dealership service; to proceed, schedule service and check current service specials to save.

2013 Ford Fiesta Check Engine Light Codes

In Lakewood, CO, our technicians frequently see codes on the 2013 Ford Fiesta such as P0300 (random/multiple misfires), P0420 (catalyst system efficiency low), P0171 (system too lean), P0455 (EVAP large leak), and P0135 (O2 sensor heater circuit). Ignoring these codes can escalate costs: untreated misfires shorten engine life and can ruin a catalytic converter (repairs often exceed $1,000), EVAP leaks reduce fuel economy and may fail emissions inspections, and faulty oxygen sensors cause rich/lean running that increases fuel consumption and component wear. At Larry H. Miller Ford Lakewood we diagnose quickly, explain potential costs and savings, and perform repairs with OEM parts to ensure long-term reliability. Many customers find dealership service provides immediate and long-term savings versus patchwork fixes. We also provide service financing and honor warranty requirements — warranty-covered repairs must be completed at a certified dealership.
