This TSB supersedes article 24-2036 to update the vehicles affected. Some 2023-2024 F-Super Duty pickup vehicles built on or before 02-Jan-2024 equipped with a 6.7L engine may exhibit an illuminated MIL with diagnostic trouble codes (DTC) P0133, P0139, and/or P0145 stored in the powertrain control module (PCM). This may be due to the software in the PCM and does not affect vehicle operation.
