Application and function

The Alliant Power AP63400 is a camshaft position (CMP) sensor engineered for 1997–2003 Ford 7.3L Power Stroke applications—including F‑250/F‑550, F‑650/F‑750, Excursion, and E‑Series—as well as 1997–2003 Navistar T444E engines. As a direct replacement for the factory sensor, it provides the correct camshaft reference signal so the PCM can control injection timing, supporting quick starts, stable idle, and consistent drivability in diesel fleets.

Fitment and installation

Built to match OE fit, form, and function, the AP63400 installs in the original location and connects to the existing harness with no modifications on specified models. It is marketed as a cost‑effective alternative to OEM sensors while maintaining timing accuracy required by the 7.3L Power Stroke and T444E. Common OE cross‑references include Ford F7TZ‑12K073‑A/B and Navistar 1825899C93 and 1876735C91, simplifying sourcing and interchange. Typical applications span model years 1997–2003 across Ford Super Duty trucks and E‑Series vans, plus medium‑duty F‑650/F‑750 configured with the 7.3L diesel.

Support you can specify

Alliant Power supports this component with a 24‑month, unlimited‑mileage warranty and access to technical assistance for diagnostics and part cross‑reference. For fleets and service shops, the combination of drop‑in installation and OE‑level signal integrity helps reduce comeback risk when replacing failed CMP sensors on these engines.
