Official summary
Some 2021-2023 Bronco vehicles equiped with a 2.7L engine may exhibit an ilumintated MIL with DTC P0456 stored in the powertrain control module (PCM). This may be due to the software level of the PCM and has no effect on vehicle operation.

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.
