Ford PC3A-12B579-AB Air Flow Sensor Mass Air Flow Meter Precise Measurement

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.
