Camshaft Position Sensor for Navistar T444E/DT466E/DT530E

The PAI 450651 is an aftermarket camshaft position (CMP) sensor, designed as a replacement for Navistar OEM part number 1876736C91 and its equivalents, including the 1820009 and 1821720 series. This sensor is engineered for Navistar T444E, DT466E, and DT530E HEUI engines produced from 1994 onwards. It features a three-pin oval female connector, which is crucial for feeding the Engine Control Module (ECM) the precise cam-tooth signal. This signal is essential for accurate fuel-injection timing, operational sequence, and determining engine speed. Applications include the Navistar T444E 7.3L (1994–1996, also compatible with Ford 7.3L Power Stroke), Navistar DT466E 7.6L HEUI (1994 onward), and Navistar DT530E 8.7L HEUI (1994 onward). Representative vehicles such as the Ford F-Series and E-Series (1994–1997), International 4700/4800/4900 series (1995–2003), and school bus chassis (Blue Bird, IC, Thomas Saf-T-Liner) equipped with these engines are compatible. It is important to verify engine generation, as post-1997 Ford 7.3L Power Stroke and 1997+ DT466E engines may have had different CMP sensor revisions; matching connector keying and harness pigtail length is advised before purchase.
