Manufacturer summary

Original wording in English

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 of the PCM. Engineering is currently investigating this concern. To temporarily address this issue, clear the DTC and run the PCM - Reset the Keep Alive Memory (KAM) application in the Ford Diagnosis and Repair System (FDRS). Inform the customer they can continue to drive the vehicle. Monitor OASIS for additional updates.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
