福特 PC3A-12B579-AB 空气流量传感器 质量流量计 精准测量

When your Ford shows idle instability, sluggish acceleration, abnormal fuel consumption, or MIL, it’s likely the MAF sensor is aging or carbon-fouled causing signal drift. This sensor precisely measures incoming air mass and transmits data to the ECU to control fuel injection and ignition timing, ensuring optimal air-fuel ratio. OEM: PC3A-12B579-AB; fits Ford Focus, Mondeo, Kuga, and other models. Install with original clamp to avoid housing distortion; ensure intake duct sealing to prevent leaks that affect measurement accuracy.
