Manufacturer summary

Original wording in English

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.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
