6.0 PS USA Made IPR Valve and ICP Sensor Kit - Includes brand new USA Made Injection Pressure Regulator and Injection Control Pressure Sensor. Fits all 9/2003 - 2010 Ford 6.0 Diesel. The IPR valve and ICP sensor work together as part of a feedback cycle to control the oil pressure to the injectors in the HEUI fuel system. The ICP reports the actual pressure to the PCM which then makes an adjustment in the position of the IPR valve to bring actual pressure into sync with desired pressure. Failure of either part can cause a range of driveability symptoms including no-starts. These parts are frequently replaced together.
