Cummins 5297640 Fuel Rail Pressure Sensor

The Cummins 5297640 is a high-pressure fuel rail sensor designed for common rail diesel injection systems. It converts fuel rail pressure into an electrical signal for the engine control module (ECM) to regulate injection timing and quantity. This sensor replaces superseded part numbers 5261237, 4937283, and 4929611. It is engineered for 2007.5 through 2012 model year 6.7L Cummins ISB and QSB engines found in Dodge Ram 2500 and 3500 series trucks, as well as various industrial and marine applications utilizing the QSB platform. The sensor features a robust stainless steel housing with a sealed electrical connector to withstand high vibration and extreme temperature cycles inherent in heavy-duty diesel environments.
