Some 2018 F-150, Expedition, Navigator, Transit and Explorer vehicles may exhibit an illuminated MIL with DTC P025A stored in the powertrain control module (PCM). This may be due to an intermittent or partial disconnect of the harness to the fuel pump driver module (FPDM) connector. Confirm FPDM connector (F-150 C4336, Expedition/Navigator C433, Transit C433, Explorer C3239) is fully seated prior to performing PC/ED diagnostics or replacing any components. Engineering is investigating, monitor OASIS for updates.
