This Mass Air Flow (MAF) sensor is designed to accurately measure the volume and density of air entering the engine's intake system. By providing this crucial data to the engine control unit (ECU), it enables precise adjustments to the fuel injection and ignition timing. Proper functioning of the MAF sensor is essential for maintaining optimal engine performance, fuel efficiency, and reducing emissions. A faulty sensor can lead to various drivability issues, including rough idling, hesitation, poor acceleration, and increased fuel consumption. Manufactured by PIERBURG, a trusted name in automotive components, this sensor is built to meet stringent quality standards. It is a direct replacement for the original part, ensuring a proper fit and reliable operation.
