How to remove and reinstall the Mass Airflow (MAF) sensor on 2007 through 2015 Toyota Avalon?

The Mass Air Flow Sensor, technology that measures the amount of air entering the engine, is typically located on the air intake duct. Before starting, ensure that the ignition key is in the OFF position to prevent any injury or accidents. To remove it, first disconnect the electrical connector. Then, unscrew the retaining bolts. Remove the MAF sensor. To perform an installation, you can simply follow the exact opposite steps that were taken during the removal process.

What is the location and function of the Mass Airflow (MAF) sensor on 1997 through 2001 Toyota Avalon?

The Mass Air Flow Sensor, located on the air intake duct, is a system circuit with a platinum hot wire, a thermistor, and a control circuit within a plastic housing. This setup detects changes in intake air temperature. When the throttle opens, more air cools the wire, causing the PCM to increase the current flow to maintain a constant temperature. The MAF sensor's output voltage signal varies with this current flow, and the PCM measures this, turning the injectors on and off accordingly. A problem in this circuit sets a diagnostic trouble code. To check the MAF sensor, first check for power to it, looking for 9-14 volts between terminal number 4 and the ground. If voltage is absent, check the circuit between the EFI main relay and the MAF sensor. Next, check the MAF sensor voltage signal to the PCM by back-probing the MAF sensor connector. If the indicated signal voltage is out of range, inspect the wiring harness for bad connections, open circuits, or damage. If these are fine, the MAF sensor might be faulty, but given its cost, consider having the circuit checked before replacing it. For removal, turn the ignition key to OFF, disconnect the electrical connector from the MAF sensor, and remove the air cleaner assembly, and the two sensor retaining bolts to remove the MAF sensor and gasket. Installation is the reverse of removal, with a new gasket or O-ring 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.
