- Summary
- Some 2020-2021 F-Super Duty vehicles equipped with a 6.7L engine may exhibit an illuminated malfunction indicator lamp (MIL) with various fuel system related diagnostic trouble codes (DTC) stored in the powertrain control module (PCM). While performing pinpoint test (PPT) M in the Powertrain Control/Emissions Diagnosis (PC/ED) Manual, the fuel pressure control valve (F_PCV) and/or fuel volume control valve (F_VCV) parameter identifications (PIDs) may not have an option to manually command them with the Ford Diagnosis and Repair System (FDRS) scan tool. This may be due to the PCM software. To correct the condition, follow the Service Procedure to reprogram the PCM.
