161-1703 Low Pressure Sensor Description
The YNF16403 Low Pressure Sensor (OEM reference 161-1703) is a safety-critical component used in excavators and diesel-powered equipment to monitor low oil or fuel pressure conditions. This sensor is designed to activate alerts or shutdown protocols when pressure drops below a safe operating threshold, preventing costly engine damage. Built with a sealed connector and pressure-sensitive diaphragm, it maintains stable readings under continuous use. It’s widely installed in hydraulic systems, engine lubrication circuits, and diesel fuel supply lines. Ideal for B2B parts dealers, service centers, and heavy equipment operators who prioritize safety and system reliability.
