2017 Ford Focus ST Check Engine Light Codes

Common check engine codes for the 2017 Ford Focus ST often relate to sensors (O2, MAF), ignition misfires, and turbo system sensors. Left untreated, a failed O2 or MAF sensor can reduce fuel economy and increase emissions; unresolved misfires can damage pistons and the catalytic converter, which are far more expensive to replace than the sensor or ignition coil.
