The YNF16397 Intake Pressure Sensor (OEM ref: 197-8393) is a high-precision manifold absolute pressure (MAP) sensor designed for diesel-powered construction equipment. It detects changes in the intake manifold pressure and sends real-time data to the engine’s ECU for optimal fuel injection and turbo boost control. This sensor is essential for achieving efficient combustion, reducing emissions, and preventing engine overload under variable loads. With a sealed design and robust electronics, it provides long-lasting performance in high-vibration, high-heat environments. Widely stocked by B2B parts suppliers, this sensor is a critical item for engine diagnostics and control system maintenance.
