Some 2018-2019 EcoSport vehicles equipped with a 1.0L EcoBoost engine and an automatic transmission may exhibit an illuminated malfunction indicator lamp(MIL) with multiple diagnostic trouble codes (DTC) stored in the powertrain control module (PCM) relating to loss of power or misfire conditions. This may be due to a chafing condition on the engine control harness that is routed between the transmission and exhaust heat shield. To correct the condition, follow the Service Procedure steps to repair the wiring harness and move the heat shield away from the harness.
