Genuine 22204-38020 Mass Air Flow Sensor Meter Assembly

The Genuine 22204-38020 Meter Sub-Assembly is an OEM mass air flow (MAF) sensor designed to accurately measure the volume and density of air entering the engine intake system. This critical engine management component provides real-time airflow data to the engine control unit (ECU), enabling precise fuel injection calculations for optimal engine performance, fuel efficiency, and emissions control.

Key Features:

• Direct OEM replacement for Toyota/Lexus vehicles requiring part number 22204-38020
• Hot-wire or hot-film sensing element for accurate airflow measurement
• Engineered to exact factory specifications for reliable performance
• Includes integrated air temperature sensor for comprehensive intake monitoring
• Plug-and-play installation with OEM electrical connector

This genuine mass air flow sensor ensures your engine receives accurate airflow data for proper air-fuel ratio control. A faulty MAF sensor can cause rough idling, poor acceleration, decreased fuel economy, and check engine lights. Replacing a worn or contaminated sensor with this OEM component restores proper engine management function and performance.
