Manufacturer summary

Original wording in English

Some 2023 F-Super Duty vehicles equipped with vacuum assist brakes and built on or before 01-Aug-2023 may exhibit an illuminated brake warning indicator with diagnostic trouble codes (DTC) C0047 and/or P0557 present. This may be due to the brake vacuum sensor. To correct the condition, remove and replace the brake vacuum sensor, part NK4Z-2C444-A. To prevent repeat concerns, install the sensor with the electrical connector pointed towards the identification label on the vacuum brake booster.

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.
