Official summary
Some 2021-2023 F-150 vehicles equipped with a 3.3L engine may exhibit an illuminated MIL in the instrument panel cluster (IPC) with DTC P0171 stored in the powertrain control module (PCM). This may be due to the software level of the PCM. To correct this issue, follow the Service Procedure to reprogram the PCM to the latest software level using the Ford Diagnosis and Repair System (FDRS).
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.
