What this component controls or measures
An IPR controls oil pressure in applicable hydraulically actuated injection systems. It is not the same as a fuel rail pressure regulator.
Match the Right Part to Your Equipment
Include engine family, IPR valve marking and relevant high-pressure oil diagnostics.
Give the sensor marking, connector style and location on the engine. If there is a diagnostic code, include the code and the observed symptom rather than using the code as the part identification.
Replacement and diagnostic questions
Confirm oil-side system conditions and the correct valve configuration before installing a replacement.
Check connection, mounting and test results before assuming a sensor or valve is the cause of a code or symptom. Sensor nomenclature can vary across engine families and is not proof of interchangeability.
Part Names and Identification
Related part names include IPR valve HEUI, injection pressure regulator solenoid. Confirm the original number, connector and circuit before ordering.
