TSB 23-2421

Some 2023 F-Super Duty vehicles equipped with a 6.8L or 7.3L engine may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTC) P061B, U0140, U3035 and/or U3036 stored in the powertrain control module (PCM). This may be due to the software in the PCM. To correct the condition, follow the Service Procedure to reprogram the PCM.
