Official summary
Some 2017 f-super duty vehicles equipped with a 6.7l engine built on or before 24-oct-2016 may exhibit dtc p0402 in the powertrain control module (pcm). This may be due to a mass air flow (maf) sensor adaption feature which has not yet learned the appropriate values for the vehicle operating condition. Follow the service procedure steps to correct the condition.
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.
