Official summary
Some 2021 F-150 vehicles equipped with a 3.5L PowerBoost engine may experience a Motor Coolant Over Temperature message in the instrument panel cluster (IPC) and diagnostic trouble code (DTC) P0A2F:94 stored in the secondary on-board diagnostic module C (SOBDMC). This may be due to software parameters in the SOBDMC. To correct the condition, follow the Service Procedure to reprogram the PCM.
Vehicles covered
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.
