Your exhaust back pressure (EBP) sensor in your Powerstroke is a very simple part, but if it fails it could cause serious performance problems. It measures back pressure in your exhaust and communicates with the PCM, controlling the amount of boost produced. A failure could reduce boost, causing both a loss of power and fuel economy.
This EBP from Alliant Power for your 6.0L Powerstroke is made and tested to Ford's OEM specifications and are quality replacement parts. This exhaust back pressure sensor replaces the Ford Super Duty OEM part numbers 5C3Z9J460A, 5C3Z9J460B and Motorcraft DPFE6, and fits a 2005, 2006, or 2007 Ford F-250/F-350/F-450/F-550/Excursion with a 6.0L Powerstroke engine, or 2003, 2004, 2005, 2006 or 2007 F-650/F-750 Powerstroke 6.0L.
