TSB 19-2344

Some 2019 F-Super Duty pickup vehicles equipped with a 6.7L engine built on or before 31-Oct-2019 may exhibit an illuminated malfunction indicator lamp (MIL) with only diagnostic trouble code (DTC) P0170 stored in the powertrain control module (PCM). This may be due to various strategies within the PCM software. To correct the condition, follow the Service Procedure steps to reprogram the PCM and perform a mass airflow (MAF) sensor parameter reset.
