| TSB 22-2260 | 2023-01-31. Service bulletin. FUEL SYSTEM, DIESEL:STORAGE:TANK ASSEMBLY. Some 2018-2020 F-150 vehicles equipped with a 2.7L EcoBoost and 2020-2021 Expedition/Navigator vehicles may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTCs) P0420 and/or P0430 stored in the powertrain control module (PCM). This may be due to high sulfur content in the fuel. To correct the condition, follow the Service Procedure to de-sulfate the catalytic converters. |
