| 21N06 | 2021-09-05. Service bulletin. This program extends the warranty coverage of the catalytic converter portion of the selective catalyst reduction (SCR) system for twelve months of service, beginning on the date the powertrain control module (PCM) is reprogrammed under Emissions Recall 21E01. This program only applies if an SCR (converter) fault is detected and it is related to a diagnostic trouble code (DTC) P20EE identified after 21E01 has been performed. This is a one-time repair. |

| SSM 49065 | 2020-09-04. Service bulletin. 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. |
