Application & Function
The Alliant Power AP63429 is a dual-function pressure sensor for heavy-duty diesel platforms. It operates as a Manifold Absolute Pressure (MAP) sensor on 1998–2003 Navistar DT-series engines (DT466E, I530E, DT466, DT530, HT530), mounting directly on the intake manifold. The same part functions as an Exhaust Back Pressure (EBP) sensor on 1994–1997 Ford 7.3L Powerstroke engines used in F-Series and E-Series vehicles. Typical chassis coverage includes International 4700, 2674, 7500, 5600i, 5500i and Ford F-250/F-350 of the applicable years. OEM cross: 1840078C1.
Performance & Reliability
AP63429 provides accurate pressure feedback critical to engine management and emissions control, enabling stable MAP and EBP signals across demanding operating conditions. It consolidates coverage for fleets that operate both Navistar DT platforms and early Ford 7.3L applications, reducing SKU count and simplifying stocking. Manufactured in China to Alliant Power specifications and supported by a 24-month warranty, the sensor is built for dependable performance in diesel environments. Also referenced in some catalogs as DPFE1, this unit is a practical drop-in solution where the MAP or EBP sensor is flagged during diagnostics.
Note: California Proposition 65 warning applies.
