This article supersedes TSB 23-2425 to address revised software and update the Parts List. Some 2022-2023 F-150 hybrid vehicles equipped with a 3.5L PowerBoost engine may exhibit an illuminated MIL with diagnostic trouble codes (DTCs) P0420 and/or P0430 stored in the powertrain control module (PCM). This may be due to calibration and controls sensitivity. To correct the condition, follow the Service Procedure to reprogram the PCM and perform the catalyst stabilization drive cycle.
