2023 Ford Fusion Check Engine Light Codes

The 2023 Ford Fusion commonly registers codes related to oxygen sensors, catalytic converters, ignition misfires, and evaporative emission systems. In Mesa, AZ, Larry H. Miller Ford Mesa analyzes those codes with OEM diagnostic tools to determine whether a sensor replacement, spark component service, or emission repair is required. Left unchecked, an O2 sensor fault can reduce fuel economy and damage the catalytic converter—costing hundreds to thousands more than the repair if delayed. A misfire left unattended can harm the engine and cause expensive repairs; a timely diagnosis and repair at our facility often save drivers significant long-term expense. Our certified technicians explain each code, provide a clear repair estimate, and highlight immediate and future savings of addressing issues early. For convenience, you can schedule service online and explore any current service specials to lower your upfront cost.
