Official summary
Some 2020 Explorer/Aviator/Police Interceptor Utility vehicles equipped with all wheel drive (AWD) built on or before 20-Mar-2020 may exhibit various warning/fault messages with diagnostic trouble codes (DTCs) C0633 and/or C00A6:07 stored in the AWD module. This may be caused by an oil contaminated front halfshaft speed sensor. To correct the condition, follow the Service Procedure step to replace the front halfshaft speed sensor.
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.
