Manufacturer summary

Original wording in English

This article supersedes TSB 20-2336 to update the Title, Issue, Action, vehicles affected and production fix date. Some 2020-2021 F-Super Duty vehicles equipped with a 6.7L engine built on or before 10-Feb-2021 may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTCs) P0300-P0308, P054F, P0603, P203B, P208B, P208C, P20EE, P2201, P24C2, P27B4, and/or P27B5 stored in the powertrain control module (PCM). The vehicle may also exhibit a forced idle condition. This may be due to various strategies within the PCM software. To correct the condition, follow the Service Procedure to reprogram the PCM.

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.
