Manufacturer summary

Original wording in English

Some 2019-2020 F-150 vehicles equipped with a 5.0L flex fuel engine may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTC) P0171, P0172, P0174 and/or P0175. This may be due to software parameters in the powertrain control module (PCM). To correct the condition, follow the Service Procedure to reprogram the PCM.

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.
