The DELPHI AF10316-12B1 Mass Air Flow (MAF) sensor is engineered to precisely measure the volume and density of air entering the engine's intake system. This critical data is then relayed to the engine control unit (ECU) to determine the correct amount of fuel to inject for efficient combustion. A malfunctioning MAF sensor can lead to various drivability issues, including poor fuel economy, rough idling, hesitation, and even engine stalling. Replacing a faulty sensor with a high-quality part like this DELPHI unit helps restore optimal engine performance and emissions control. This sensor is designed to meet or exceed original equipment specifications, ensuring a reliable fit and function. Trust DELPHI for components that contribute to your vehicle's overall health and performance.
