Cummins ISX Oil Pressure Sensor Identification: Cummins Isx Oil Pressure Sensor Location
The Cummins ISX oil pressure sensor is a critical component of the engine’s lubrication system, responsible for monitoring and transmitting oil pressure data to the engine control module (ECM). This information is crucial for ensuring optimal engine performance and preventing potential damage due to insufficient lubrication.
Technical Specifications
- Sensor Type: Piezoresistive
- Pressure Range: 0-1000 psi (0-69 bar)
- Accuracy: ±2% full scale
- Operating Temperature Range: -40°F to 250°F (-40°C to 121°C)
- Electrical Connection: 3-pin connector
Design and Components
The Cummins ISX oil pressure sensor consists of a pressure-sensitive diaphragm, a piezoresistive element, and an electrical connector. When oil pressure is applied to the diaphragm, it deflects, causing a change in the resistance of the piezoresistive element. This resistance change is then converted into an electrical signal, which is transmitted to the ECM.
