The purpose of an automotive mass airflow sensor is to measure the amount of air entering the engine intake system. This information is important for calculating the desired fuel-to-air ratio for efficient combustion in the engine. By providing data about the mass or density of the air, the mass airflow sensor assists the engine control unit (ECU) in making adjustments to the fuel injection timing and quantity, ensuring optimal performance, fuel economy, and emissions control.

The purpose of an automotive mass airflow sensor is to measure the amount of air entering the engine's intake system. It measures the mass of the air rather than just the volume, allowing the engine control unit (ECU) to accurately calculate the amount of fuel needed for efficient combustion. This helps maintain the optimal air-fuel ratio, improves fuel efficiency, and ensures the engine runs smoothly. The mass airflow sensor also plays a crucial role in controlling emissions and can contribute to various engine functions such as turbocharger control, idle speed control, and diagnostics.
