The Mass Air Flow Sensor also called MAF in Toyota Avalon cars helps the car to maintain its performance level by an identifying and controlling the rate of air mass which enters the engine. This information is transmitted to the Power train Control Module more commonly known as PCM which in turns fine tunes the fuel injector timing for the right mixture of air and fuel for combustion. There are varied Mass Air Flow Sensors used in Toyota Avalon, which have changed with time; they include the Vane Meter (VAF) and Hot Wire sensors. The VAF sensor while it gets the job done reduces airflow and is prone to mechanical wear. The Hot Wire sensor on the other hand, provides better accuracy and flexibility and is less sensitive to contaminants. Regular cleaning or checking of the MAF sensor is very important since it can lead to some problems such as stalling of the Avalon or having wrong air-fuel ratios require the Avalon to be at its optimal level.
