What is the most common reason for check engine light on a 2020 Ford Shelby GT500?

• The most frequent culprits are sensor-related: oxygen (O2) sensors, mass air flow, or MAF sensors, as well as ignition or fuel system irregularities. High-performance engines like the 2020 Ford Shelby GT500 may also experience issues tied to forced-induction systems and related sensors.

• Do not ignore intermittent or persistent lights — especially if the light is flashing. For immediate attention, use the schedule service link to set an appointment.
