Walker Products 245-1668 Mass Air Flow Sensor MAF Sensor

The Walker Products 245-1668 is a direct-fit replacement Mass Air Flow (MAF) sensor engineered to restore precise airflow measurement and proper engine management. As a critical component in modern engine management systems, the MAF sensor detects changes in air mass entering the engine and converts those measurements into an electrical signal sent to the vehicle's ECU. The ECU uses this data to accurately calculate fuel delivery for optimal combustion efficiency, performance, and emissions control.

Key Features:

• 100% New — Never Remanufactured: Every Walker MAF sensor is a brand-new unit, not a rebuilt or remanufactured part
• OE Fit, Form & Function: Direct-fit replacement designed to meet or exceed original equipment performance and calibration standards
• 100% Programmed & Tested: Each sensor is fully programmed and tested for fit, form, and function before sale, including on-vehicle calibration verification
• Custom-Tuned Flow Characteristics: Walker engineers develop sensors with tuned flow characteristics across the full flow spectrum to maintain correct long-term fuel trim percentages
• High-Quality Construction: Built with premium components and materials to resist heat, vibration, and air contamination for long-lasting reliability
• USA Engineered: Many Walker MAF sensors are designed and manufactured in Walker Products' USA facilities using OEM-quality components and custom-engineered circuit boards
• ISO 9001 / IATF 16949 Certified Manufacturer: Produced under stringent quality management standards

A failing MAF sensor can cause a variety of drivability issues including hard starting, engine surging or stalling, rough idle, hesitation under acceleration, and an illuminated Check Engine Light (CEL). The Walker Products 245-1668 MAF sensor is a straightforward plug-and-play replacement that can resolve these symptoms and return your vehicle to proper operating condition. Note: MAF sensors are non-serviceable — replace any unit that is non-functional.
