2013 Ford Focus ST Check Engine Light Codes

Common codes for a 2013 Ford Focus ST in Brownsburg include P0300 (random/multiple misfires), P0420 (catalyst system efficiency), and P0101 (mass airflow sensor). Left unaddressed, P0300 can lead to catalytic converter overheating and replacement costs that far exceed initial ignition repairs. P0420 may begin as a sensor fault but can escalate into full catalytic replacement and higher emissions failures. P0101 affects drivability and fuel economy — leaving it can increase fuel costs and degrade engine performance. At Bill Estes Ford Brownsburg we prioritize efficient, accurate diagnostics to prevent escalation: our factory-trained technicians use Ford-specific tools to read live data, test components, and provide a transparent estimate. Because we use OEM parts and follow Ford repair procedures, customers realize immediate benefits—fewer return visits, longer component life, and better resale value. We also offer service financing and rotating service specials to reduce out-of-pocket expense. Book service online via schedule service to protect your investment and get back on the road with confidence.
