What is MAF Sensor and his Location

What is MAF Sensor and his Location :

MAF sensor full form is (mass airflow sensors). This sensor determines the amount of air that passes during the section stroke in the engine. That is, it measures the air going into the engine cylinder and gives the information in the form of data to the ECM. Then the ECM injects petrol accordingly.

MAF Sensor Types :

There are two common types of mass airflow sensors in use on automotive engines

  1. Hot wire type
  2. Hot film type (vane meter)

Location of MAF sensor :

It is always installed after the air cleaner and before the throttle body.

About MAF sensor in EFi Field by AI :

The term “MAF sensor EFi” seems to be a combination of two different components related to automotive engines. Let’s break it down:

  1. MAF Sensor: MAF stands for Mass Airflow Sensor. It is a device used in modern fuel-injected engines to measure the amount of air entering the engine. The MAF sensor detects the mass of air flowing into the engine and sends this information to the engine control unit (ECU). The ECU then calculates the amount of fuel required for efficient combustion based on the air-to-fuel ratio.
  2. EFi: EFi stands for Electronic Fuel Injection. It is a fuel delivery system used in modern engines that replaces traditional carburetors. EFi systems use electronic sensors and actuators to precisely control the fuel flow into the engine cylinders, optimizing performance and fuel efficiency.

So, “MAF sensor EFi” could refer to the combination of a Mass Airflow Sensor (MAF) used in conjunction with an Electronic Fuel Injection (EFi) system. The MAF sensor measures the incoming air, while the EFi system adjusts the fuel delivery based on that information to maintain the desired air-to-fuel ratio for efficient combustion.
