Official summary
Some 2021 F-Super Duty and 2021-2022 F-650/F-750 vehicles equipped with a 6.7L engine and built on or after 15-Apr-2021, with less than 300 miles (483 km), may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTC) P20E8 and/or P208B stored in the powertrain control module (PCM). This may be due the reductant pump and heater assembly losing prime during extended vehicle storage. To correct the condition, follow the Service Procedure to prime the reductant pump and heater assembly.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
