Official summary
Some 2020-2022 Explorer vehicles equipped with a 2.3L EcoBoost engine may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P04F0 and/or P144C stored in the powertrain control module (PCM). This may be due to loose or partially connected evaporative emissions (EVAP) vapor lines. To correct the condition, follow the Service Procedure to make sure the EVAP vapor lines are properly connected.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
