Engine mass air flow sensor
ChatGPT
Mass air flow sensors in a car's engine measure the amount of air flowing into the engine. The ECM converts this information into electrical signals, which are used to adjust the ratio of fuel to air burned in the cylinders, helping to improve engine efficiency and reduce exhaust emissions.
The sensor usually consists of a group of thin ionizable wires, which are placed in the path that passes the air flow to the engine. Once air passes over these wires, electrical signals are generated in them proportional to the speed and amount of flow.
The mass air flow sensor is connected to the engine control unit by electrical wires, and the amount of fuel and the percentage of air burned in the cylinders are adjusted based on the electrical signals from the sensor. The sensor must be clean and intact to maintain accurate measurements and maintain engine efficiency.
