Some 2013-2019 Ford F-Super Duty trucks equipped with a 6.7L diesel engine may exhibit an illuminated MIL with only DTC P2074 stored in the PCM. This may simply be due to a dirty/clogged air filter. Replace as needed. Do not replace the PCM or MAF (mass airflow) sensor for this concern. Check the simple stuff first.
