2017 Ford Shelby GT350 Check Engine Light Codes

The 2017 Ford Shelby GT350 frequently reports a set of common diagnostic trouble codes: misfire codes (P0300–P0308) indicating ignition or fuel delivery problems; oxygen sensor codes (P0135–P0161) affecting fuel trim and emissions; catalytic converter efficiency codes (P0420) that often stem from sensor or exhaust deterioration; and EVAP system leak codes (P0440–P0455) tied to fuel vapor containment.
