Some 2021 Expedition/Navigator vehicles may exhibit a no start, engine runs rough, or misfires condition. There may also be an illuminated malfunction indicator lamp (MIL) with any of the following diagnostic trouble codes (DTC) codes: P0201, P0202, P0203, P0204, P0205 or P0206. Follow the appropriate Pinpoint Tests in the Powertrain Control/Emissions Diagnosis Manual (PC/ED) for the DTCs received. If PC/ED diagnostics lead to replacement of a fuel injector, inspect the injector harness connections for possible spread terminals. Injector harnesses are available for service.
