Product Description
The Cummins 5297641 OEM Fuel Rail Pressure Sensor is the factory-correct electronic sensor used on 2003–2007 ISB 5.9L Common Rail Cummins engines to monitor high-pressure fuel delivery. This sensor provides real-time feedback to the ECM, ensuring proper injection timing, fuel quantity, idle quality, and responsiveness. A failing or inaccurate rail pressure sensor can cause hard starts, derates, smoke, or poor drivability—making a genuine Cummins replacement essential for restoring OEM performance.
Avoid misfires, low-power conditions, and false trouble codes caused by aftermarket sensors. The 5297641 fuel rail pressure sensor is engineered by Cummins for exact calibration, durability, and fault-free ECM communication.

FAQ
What symptoms indicate a failing fuel rail pressure sensor?
Common symptoms include hard starts, surging, low power, erratic idle, white smoke, or rail pressure–related fault codes.
Is this sensor the same as the MAP sensor?
No. The 5297641 monitors rail fuel pressure, while the MAP sensor measures boost and manifold pressure.
Should this sensor be replaced during injector or pump replacement?
Yes. Many technicians replace the fuel rail pressure sensor as preventative maintenance during major fuel system service.
Is calibration required after installing this sensor?
No manual calibration is required. The ECM automatically reads the new sensor's values when installed.
