Product Description
The genuine Cummins 5297640 Fuel Rail Pressure Sensor is engineered to restore factory-accurate rail pressure feedback for your 6.7L ISB/QSB engine (model years 2007.5–2012). It sits at the end of the common-rail and communicates real-time pressure data to the ECM for optimal fuel injection timing and performance.
This sensor is a direct-fit, OE-spec unit built by Cummins, delivering precise signal accuracy, full sealing integrity and durability to meet the demands of the high-pressure fuel rail environment. Common symptoms of a failing sensor include hard starting, rough idle, black smoke, loss of power or fault codes such as P0193/P0191.

Why Choose Genuine Cummins?
Using the genuine Cummins part ensures proper calibration, accurate pressure sensing and seamless integration with your engine’s ECM logic. Aftermarket units may introduce inaccuracies that trigger fault codes or degrade performance. When you want the best outcome for your investment, trust Cummins-branded OEM.
Installation Tips
Before installing, depressurize the fuel system per manufacturer instructions. Ensure the port and surrounding area are clean to avoid contamination. Inspect the wiring harness and connector for damage or oil saturation. Torque the sensor to specification and clear all fault codes. After installation, monitor actual vs commanded rail pressure for correct function.
FAQ Will this fit my 2007.5-2012 6.7L Cummins Ram?
Yes — the Cummins 5297640 is the OE rail pressure sensor for 2007.5-2012 Ram 2500/3500 and many 4500/5500 cab-&-chassis applications.
What about 2013-2018 trucks?
Most 2013-2018 6.7L Cummins use part numbers 4306993 / Mopar 68210175AA instead. Some cab-&-chassis overlap may exist—always confirm by VIN/ESN.
Where is the sensor located?
It is mounted at the end/rear of the high-pressure fuel rail, passenger side.
What trouble codes can a bad sensor trigger?
Commonly P0193 (“Fuel Rail Pressure Sensor Circuit High Input”) and sometimes P0191, along with drivability issues.
Is this a genuine Cummins part?
Yes — this is the factory Cummins 5297640 with full OEM specification.
