The DELPHI Mass Air Flow (MAF) Sensor, part number AF10480-12B1, is engineered to precisely measure the amount of air entering your engine's intake system. This critical data is then sent to the engine control unit (ECU) to help determine the correct amount of fuel to inject for efficient combustion. By providing accurate airflow readings, this sensor plays a vital role in maintaining optimal engine performance, fuel economy, and emissions control. A malfunctioning MAF sensor can lead to various drivability issues, including rough idling, poor acceleration, increased fuel consumption, and check engine lights. DELPHI is a trusted name in automotive components, known for producing high-quality parts that meet or exceed original equipment specifications. This AF10480-12B1 sensor is designed for reliable and long-lasting operation, ensuring your vehicle's engine receives the precise air-fuel mixture it needs to run smoothly.
