How Does the Mass Air Flow Sensor Function in the Air Intake System of a 2002-2006 Toyota Avalon?

The Mass Airflow (MAF) sensor is mounted on the intake duct and consists of the hot wire of platinum, the thermo resistor, and the control circuit placed within the body of the plastic. It uses hot wire sensing element to measure molecular weight of air for intake into the engine. With the release of throttle more volume of air passes over the hot wire, and hence it cools down. The MAF sensor circuiting is worked in such a manner to maintain hot wire preset at specific temperature by regulating the flow of current through the element. Therefore, as the wire cools down, the PCM raises the current in endeavors to retain higher temperatures, and this leads to a fluctuating output voltage signal that the PCM records. The above signal is in the form of an analog waveform which is then converted to a digital waveform required in fuel injector pulse width modulation and controlling the injectors. If there is a failure in MAF sensor circuit an an indication as a check code will appear. When starting diagnosis, the ignition key should be in the OFF position, and then, remove the electrical connector from MAF sensor and pay attention to two mounting screws and connector. Subsequently pull out the MAF sensor after loosening two retaining bolts and then take out the O-ring from the air intake duct. Reassembly is basically the reverse of disassembly, but a new O-ring is fitted in-between the MAF sensor and the intake duct.

Toyota Avalon Mass Air Flow Sensor

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.
