Official summary
Some 2021 Transit vehicles equipped a 3.5 EcoBoost engine and built on or before 01-Jul-2021 may experience an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTC) P0300, P0301-P0306 and/or P0316. This may be due to the software in the powertrain control module (PCM). To correct this condition, follow the Service Procedure to reprogram the PCM.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
