Some 2018-2019 EcoSport vehicles equipped with a 2.0L Duratec engine and an automatic transmission and built on 1-Sep-2017 and through 28-Nov-2018 may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTCs) P0137 and/or P0141. This may be due to a faulty catalyst monitor sensor (CMS) as well as powertrain control module (PCM) software. Follow the Service Procedure steps to correct the condition.
