Ford Mass Air Flow Sensor LC3A-12B579-BB (LC3A12B579BB) high-precision sensing

When your Ford vehicle shows rough idling, delayed acceleration, abnormal fuel consumption, or check engine light, the issue is likely aging of the mass air flow sensor causing signal deviation. This part, working normally, monitors incoming air with high-precision real-time data and transmits to ECU to precisely control injection and ignition, ensuring smooth power and fuel economy. OEM number LC3A-12B579-BB (LC3A12B579BB), fits Ford Focus, Mondeo, Kuga and other models with 2.0T EcoBoost engines. On installation, disconnect the negative battery, clean air intake interfaces, avoid touching sensor, after installation use a diagnostic tool for idle learning/matching.
