mass airflow sensor

The **mass airflow sensor** is a crucial component in modern automotive engines, responsible for measuring the amount of air entering the engine’s intake system. This information helps the engine control unit (ECU) precisely regulate the air-fuel mixture for optimal combustion, improving performance, fuel efficiency, and reducing emissions. Commonly abbreviated as MAF sensor, it plays a vital role in engine management systems and is often a key focus during diagnostics and maintenance routines. Understanding the mass airflow sensor can help vehicle owners and mechanics identify issues related to engine hesitation, poor fuel economy, and check engine lights.
