SSM 54736

Some 2026 Mustang vehicles built on or before 01-Dec-2025 and equipped with a 5.0L or 2.3L engine may exhibit various drivability symptoms and/or have diagnostic trouble codes (DTCs) stored in the powertrain control module (PCM) related to throttle/pedal position circuits. This may be caused by a spread terminal at the PCM connector. Inspect for loose fitting terminals at C1551B for 2.3L vehicles, and C175B on 5.0L vehicles. Refer to the appropriate wiring diagram sections for circuit identification and wiring repair information. Wire terminal repair kit part DU2Z-14474-CA is recommended for this repair. For claiming, use causal part 14290 and labor operations 12651D, 12651D45 and 12651D45WR. Monitor Professional Technician System (PTS) for additional updates.
