20B412020-12-05. Service bulletin. FUEL SYSTEM, GASOLINE; ENGINE; EQUIPMENT ADAPTIVE/MOBILITY; EQUIPMENT. Certain 2020 Model Year Super Duty and 2021 Model Year Medium Duty Vehicles Equipped with a 6.7L Engine Left Hand Side High Pressure Fuel Rail Replacement. In some of the affected vehicles, the vehicle may have been built with a high pressure fuel rail where the internal fuel orifice may become dislodged. If the fuel orifice becomes dislodged, it can travel down and damage the pressure control valve pintle resulting in a Diagnostic Trouble Code (DTC) P0088. Before demonstrating or delivering any new in-stock vehicles involved in this program, dealers are to replace the left hand side high pressure fuel rail using the technical instructions, even if DTC P0088 is not present. This service must be performed on all affected vehicles at no charge to the vehicle owner.
SSM 490652020-09-04. Service bulletin. ENGINE AND ENGINE COOLING; ELECTRICAL SYSTEM; FUEL SYSTEM, DIESEL. Some 2011-2020 F-Super Duty, 2015-2019 Transit, 2016-2021 F-650/F-750 and 2018-2020 F-150 vehicles equipped with a 6.7L, 3.2L or 3.0L engine may exhibit an illuminated MIL with diagnostic trouble codes (DTCs) P207F, P20EE, P229F, P2201 and/or P24AE. This may be a result of using aftermarket cleaning liquids or tools for the exhaust gas recirculation (EGR) cooler or intake. Ford does not recommend the cleaning of diesel intakes or EGR coolers using any aftermarket tool that injects a cleaning foam or liquid substance into the EGR cooler or intake. Using these types of fluids can result in sodium poisoning of the NOx and particulate matter (PM) sensors resulting in degraded operation and permanent damage to the after treatment system. Use of these cleaning tools may void the emissions warranty of the hot end after treatment exhaust system and the attached emissions sensors.
