Bulletin Summary
Some 2020-2022 F-Super Duty vehicles equipped with a 6.7L engine may exhibit an illuminated malfunction indicator lamp (MIL) with cylinder injection pulse offset diagnostic trouble codes (DTC) P2B11, P2B13, P2B15, P2B17, P2B19, P2B1B, P2B1D, and/or P2B1F stored in the powertrain control module (PCM) after various fuel system repairs. This may be due to incorrect learned values in the PCM. To correct the condition, allow the engine to idle for at least 6 minutes with engine coolant temperature (ECT) at or above 170ðF (75ðC). For pickup vehicles, exhaust gas temperature (EGT12) must also be at or above 475ðF (245ðC). For chassis cab vehicles, EGT13 must be at or above 450ðF (230ðC). Clear DTCs and retest. PCM replacement is not necessary for this condition.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
