Cummins 5594396 Oil Pressure Sensor Assembly

The Cummins 5594396 is an original equipment oil pressure sensor engineered for monitoring engine lubrication system pressure in heavy-duty diesel applications. This sensor supersedes part number 4088734 and is constructed with a stainless steel housing for corrosion resistance and durability in harsh operating environments. It provides critical real-time pressure data to the engine control module (ECM) for engine protection and performance management. The sensor is a direct-fit replacement for Cummins QSK60, QST30, QSK45, QSK50, K50, and 92 Series engines commonly deployed in mining trucks, hydraulic excavators, marine vessels, and power generation units.
