Standard Motor Products MAS0285 Mass Air Flow Sensor MAF

The Standard Motor Products MAS0285 is a direct-fit replacement Mass Air Flow (MAF) sensor engineered to restore precise airflow measurement and reliable engine management performance. The MAF sensor plays a critical role in the engine's fuel delivery system by continuously monitoring the volume of air entering the intake and relaying that data to the Engine Control Unit (ECU), which then calculates the correct fuel injection quantity for an efficient air/fuel ratio.

Key Features:

• 100% New Construction — Never remanufactured, eliminating the risk of residual debris that can cause premature sensor failure
• Computer-Tested Performance — Every unit is tested to verify the ECU receives accurate airflow readings under demanding engine conditions
• Dual-Heated Sensing Elements — Ensures superior performance and consistent readings across all air/fuel system configurations
• Sensing Element Bypass Structure — Specially designed bypass architecture improves detection accuracy under harsh engine operating conditions
• Platinum RTD Sensor — Custom-designed platinum Resistance Temperature Detector (RTD) delivers highly accurate airflow output across all operating conditions
• Upgraded Construction — Features thicker walls and upgraded internal components for improved durability and longevity over remanufactured alternatives
• Airflow-Calibrated — Factory-calibrated for precise airflow output, ensuring seamless communication with the vehicle's Engine Control Module (ECM)

Standard Motor Products MAF sensors are a higher-quality, precision alternative to remanufactured units. The MAS0285 is sold individually and is designed to deliver a direct OE-style fit and function, helping to eliminate drivability issues such as rough idle, poor fuel economy, hesitation, and check engine lights associated with a failing mass air flow sensor.
