Application & Function

The Alliant Power AP63418 Injection Control Pressure (ICP) Sensor is engineered as a direct OEM replacement for Ford 7.3L Power Stroke and related Navistar T444E applications. It monitors injection control pressure and relays precise data to the engine control module to maintain proper fueling strategy, stable idle, and reliable start-up performance. Calibrated to match OEM part number F6TZ9F838A, the AP63418 delivers factory-level fit and signal quality for seamless integration with existing engine management. Alliant Power supports this sensor with a 24-month, unlimited mileage warranty for confidence in demanding light-, medium-, and vocational-duty service.

Fitment & Service Notes

Common coverage includes Ford F-250 through F-750, E-Series, and Excursion equipped with the 7.3L Power Stroke, as well as Navistar/IC vehicles using the T444E. Because coverage can vary by engine serial number, verify ESN prior to ordering. The sensor mates with a standard 2‑wire pigtail; use service pigtail AP0021 if the harness connector is damaged. In field diagnostics, technicians often replace or test this ICP alongside related components such as the AP63403 Exhaust Back Pressure (EBP) Sensor and AP63429 Pressure Sensor to ensure a complete repair. Built for the thermal and vibration loads typical of diesel service, AP63418 helps reduce repeat visits and supports consistent fleet uptime.
