Rennline Mass Air Flow Sensor - 996/986/997

A Mass Air Flow (MAF) sensor measures the amount of air entering a vehicle's engine, playing a crucial role in determining the optimal air-to-fuel ratio for combustion. When functioning properly, the MAF sensor ensures efficient engine performance and fuel economy. However, symptoms of a faulty MAF sensor include reduced engine power, poor acceleration, and rough idling. Additionally, drivers may experience stalling or hesitation during acceleration, as the inaccurate air-to-fuel ratio disrupts the combustion process. Timely identification and replacement of a malfunctioning MAF sensor are essential to maintain optimal engine efficiency and prevent potential long-term damage to the vehicle.
