Summary
Some 2013-2019 F-Super Duty vehicles equipped with a 6.7L engine may exhibit an illuminated MIL with only DTC P2074 stored in the powertrain control module (PCM). This may be due to a dirty air filter, replace the filter if necessary. Do not replace the PCM or mass air flow (MAF) sensor for this concern. Instead perform a MAF parameter reset under: Toolbox > Powertrain > Service Functions > Reset/Clear Specified Function > Reset/Clear Functions > MAF Sensor. Engineering is investigating. Monitor OASIS for updates.
