MAF Sensor

MAF Sensors, found within the Electrical & Lighting > Engine Electronics section, measure the mass of air entering a vehicle's engine. This critical data is transmitted to the engine control unit (ECU) to calculate the correct fuel injection timing and amount, ensuring optimal engine performance and fuel efficiency. Typically located between the air filter and the throttle body, MAF Sensors are essential for maintaining emissions standards and preventing engine problems. These sensors utilize a hot-wire or hot-film technology to determine airflow, and a failing MAF sensor can cause symptoms like poor fuel economy, rough idling, and a check engine light. Examples of MAF Sensors we carry include Bosch parts with MPNs like 0280218116, 0280218037, and 0281002978, suitable for a wide range of passenger cars and commercial vehicles.
