Official summary
Some 2018-2019 F-150 vehicles equipped with a 3.0L diesel engine built on or before 19-Oct-2018 may exhibit an illuminated MIL with DTC P2457 stored in the powertrain control module (PCM). This may be due to missing or loose screws in exhaust gas recirculation (EGR) system bypass module. Refer to Workshop Manual (WSM), Section 303-08E. If no concerns are present with the bypass module screws, refer to the Powertrain Control/Emissions Diagnosis (PC/ED) Manual for normal diagnostics. Engineering is investigating, monitor OASIS for updates.
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.
