福特 燃油轨压力传感器 45PP3-1/45PP3-4 油压传感器 直接替换

Ford fuel rail pressure sensor 45PP3-4 (compatible with 45PP3-1) direct replacement of the OEM part; versatile. Monitors fuel rail pressure in real time and feeds signals to the ECU to regulate injection quantity; suitable for Ford Focus, Mondeo, and Territory with 2.0L or 1.5T engines. Replacement resolves rough idle, weak acceleration, or hard starting, particularly eliminating engine fault light. If fuel consumption rises suddenly, cold-start requires multiple cranks, or acceleration feels starved, consider replacement.
