This Mass Air Flow (MAF) sensor from CONTINENTAL/VDO is designed to accurately measure the volume and density of air entering the engine. By providing this critical data to the engine control unit (ECU), it enables precise fuel injection adjustments. 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, stalling, and illuminated check engine lights. Ensure your vehicle's air-fuel ratio is correctly managed with this high-quality replacement part. It is engineered to meet or exceed original equipment specifications for reliable and consistent operation.
