LLNSEAUTO Mass Air Flow Sensor (MAF) for Toyota & Lexus — OE 22204-22010, Direct-Fit, 1-Year Warranty

This replacement MAF sensor is designed as a direct-fit option for a wide range of Toyota, Lexus and Scion vehicles. Built to meet OEM specifications, it provides the airflow data the engine control unit (ECU) needs to calculate proper fuel delivery. The unit arrives ready to install after verifying the air intake housing and filter are clean.

How does this MAF sensor affect engine performance?

A precise MAF reading helps the ECU maintain the right air–fuel ratio, which supports consistent idling, steady throttle response and more efficient combustion. While not a cure-all, installing a correct MAF restores accurate airflow data to the engine management system.

• Restores accurate air mass readings for fuel calculations.
• Helps stabilize idle and throttle response when faulty MAF is replaced.
• Engineered to match OEM electrical and connector specifications.
• Fully inspected to ensure reliability under varied driving conditions.
