The IPR Valve is responsible for controlling the pressure in the high-pressure oil system on your Powerstroke engine, which in turn operates the fuel injectors. The PCM varies ICP pressure (through adjusting the IPR duty cycle) as the primary means of controlling engine power output. It is located on the back of the high pressure oil pump, which is under the fuel filter assembly. If the IPR valve fails, common results include poor idle, stalling, and even a no-start condition. This IPR Valve comes with Alliant Power's 24-month unlimited mileage warranty. Please note that only Alliant Power Dealers can process an Alliant Power warranty claim.
