Issue: Some 2021-2023 F-150 vehicles equipped with a 3.3L engine may exhibit an illuminated MIL in the instrument panel cluster (IPC) with OTC 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 (FORS).
