2026 Ford Mustang Check Engine Light Codes

Common check engine light codes for a 2026 Ford Mustang include P0300 (random/multiple misfires), P0420 (catalyst system efficiency), P0171/P0174 (fuel trim lean conditions), and P0420-related issues tied to oxygen sensors. In Deland, Coggin Deland Ford’s certified technicians translate these codes into actionable service plans: replacing faulty ignition coils or spark plugs for misfires, addressing vacuum leaks or fuel system faults for lean codes, and testing oxygen sensors or catalytic converters for emissions-related faults. Leaving these issues unaddressed can lead to reduced fuel economy, failed emissions tests, and expensive downstream repairs. Our team emphasizes convenience—quick diagnostics, OEM replacements, and transparent pricing that often costs less than independent shops when long-term service value is included. We encourage customers to review current service specials, consider service financing, and schedule service online to protect performance and avoid escalation of repair costs.
