Official summary
Some 2017-2019 F-Super Duty/2018 F-150 vehicles equipped with the 6.7L or 3.0L engines may exhibit an illuminated malfunction indicator lamp (MIL) with DTC P208E in the powertrain control module (PCM). When performing pinpoint test RK, the results of the selective catalyst reductant (SCR) dosing measurement test (RK7) may be zero or below the specified 40-50mL requirement due to urea crystals plugging the DEF injector nozzle. If the measurement is below this specified amount, perform pinpoint test step RK7 two additional times. If the specified amount is met, reinstall the reductant injector.

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.
