Car engine air meter sensor replacement for Volvo MAF sensor 9470776 Air flow sensor for engines

Product Description:

Maf sensor
OE NO.:   30777415 9470776

Applicable vehicle type: For Volvo

The automotive air flow sensor (Air Flow Sensor) is one of the most important sensors in the electronic fuel injection engine management system. It is installed on the intake manifold between the air filter and the throttle valve. Its core function is to accurately measure the engine's intake air volume (air flow rate) and convert the data into an electrical signal transmitted to the ECU (Engine Control Unit), serving as a critical basis for calculating fuel injection quantity and ignition timing, ensuring the engine achieves the optimal air-fuel ratio (14.7:1) under various operating conditions.

Core Functions and Roles

• Accurate Measurement of Intake Air Volume: Real-time monitoring of the volume or mass flow rate of air inhaled by the engine
• Optimization of Air-Fuel Ratio: Providing accurate data to the ECU to achieve precise control of fuel injection quantity
• Enhancement of Combustion Efficiency: Ensuring the air-fuel mixture concentration is moderate for more complete combustion
• Improvement of Power Performance: Dynamically adjusting fuel injection quantity according to intake air volume to enhance engine responsiveness
• Reduction of Fuel Consumption and Emissions: Avoiding overly rich or lean air-fuel mixtures to reduce fuel waste and harmful gas emissions
