Signs Your Mass Airflow Sensor is Dirty – Downey Auto Repair   The mass airflow sensor (MAF) is a critical component of your vehicle's engine management system. It measures the amount of air entering the engine and relays this information to the engine control unit (ECU), which then adjusts the fuel-air mixture for optimal combustion. A dirty or contaminated MAF sensor can cause a range of performance issues and potentially lead to engine problems.
