Summary
Some 2016-2019 Fiesta vehicles built on or before 19-Feb-2019 may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P0128 stored in the powertrain control module (PCM). This may be due to some PCM software parameters related to engine temperature. To resolve the condition, reprogram the PCM.
