COMMON RAIL PRESSURE SENSOR DELPHI 45PP4-01

This Delphi 45PP4-01 sensor is used extensively in high-pressure common-rail systems that rely on Delphi’s pump or injector technology. The sensor uses a piezo-resistive membrane to measure fuel pressure, and its resistance changes with membrane deformation as rail pressure varies. \n \nDelphi’s spec for sensors like these supports very high pressures (up to 1600–2000 bar in some versions) depending on the variant. \n

Accurate pressure reading enables the ECU to regulate the rail via the control valve, ensuring stable injection and good performance.
