Thumbnail Filmstrip of 1994-2003 7.3L Powerstroke ICP Sensor Alliant AP63418 Images
The Alliant AP63418 is the injection control pressure sensor for a 1997–2003 7.3 Powerstroke. It is the aftermarket match for Ford YC3Z-9F838-A and F6TZ-9F838-A. The sensor only. The pigtail is not included.
A bad ICP is a common no-start and hard-start on these trucks, along with a surge, a stall, or oil in the connector. Unplug it on a crank-no-start. If it fires, the sensor is lying to the PCM. On an early truck it threads into the HPOP reservoir. On a late-1999.5 through 2003 truck it is under the passenger valve cover. The warranty is 24 months, unlimited miles.
It fits 1997–2003 F-Series, E-Series, and Excursion 7.3 trucks, plus the T444E. It is not the IPR.

Oil in the connector means the sensor has leaked into the harness. Replace the pigtail with the sensor or the new one will read wrong too.

As always, EVERY part I get from Full Force is outstanding, just what I needed, priced right and delivered fast. I have NERVER had a problem with Full Force or anything that they have sold to me. I would recommend Full force and all that they sell to anyone at any time.
