2017 Ford Focus RS Check Engine Light Codes

Common check engine light codes on a 2017 Ford Focus RS include P0300 series misfires, P0420 catalytic system efficiency, P0171/P0174 fuel trim lean conditions, and oxygen sensor faults. Each code has cost implications if ignored: misfires can damage the catalytic converter and require cylinder or ignition repairs; a failing catalytic converter is expensive to replace and often follows neglect; persistent lean conditions reduce power and fuel economy and accelerate wear on the turbocharger; faulty O2 sensors degrade emissions performance and fuel efficiency. At Coggin Deland Ford in Deland, FL, we diagnose codes precisely and present repair options that emphasize long-term savings — fixing small issues early prevents expensive downstream failures. Our factory-tuned diagnostics, OEM parts, and certified technicians deliver efficient repairs and protect resale value. We also provide convenient service financing to manage repair costs and a range of service specials that make prompt maintenance more affordable. Trust Coggin Deland Ford for fast, accurate diagnostics and a clear plan to keep your Focus RS performing at its best.
