TSB 19-2065

Some 2017 Fusion Hybrid/Fusion Energi/MKZ Hybrid/C-Max and 2019 Fusion Hybrid/MKZ Hybrid vehicles built on or before 27-Jan-2019 may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P013A stored in the powertrain control module (PCM). This may be due to downstream oxygen sensor parameters in the PCM software. To resolve the condition, update the PCM software.
