TSB 21-2270

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.
