Bosch 0281002937 Common Rail Pressure Sensor

The Bosch 0281002937 is a high-pressure common rail fuel pressure sensor designed for diesel engine management systems. It measures fuel pressure in the common rail and transmits an analog voltage signal to the engine control unit (ECU) for precise injection timing and quantity control. This sensor features an M18x1.5 mounting thread and a Bosch compact electrical connector. It operates on a 5V DC supply voltage with a typical output range of 0.5V to 4.5V corresponding to a pressure range of 0 to 1800 bar. The housing is constructed from high-grade stainless steel and engineered plastics to withstand harsh under-hood environments and high-pressure fuel exposure. It supersedes part number 0281002706 and interchanges with multiple OEM references including Cummins 3974092, Volvo 3843100 and 20792328.
