OYEAUTO Maf Sensor 22204-31020 – Compatible with Toyota, Lexus, Scion (2005-2017)

Overview

The OYEAUTO Mass Air Flow (Maf) Sensor 22204-31020 is a direct-fit replacement engineered to work across a broad selection of Toyota, Lexus, and Scion vehicles from 2005 through 2017. It delivers a clean, stable signal to the engine control unit (ECU), helping the system read airflow more accurately during routine driving and under demanding conditions. Built with quality materials and tested for consistency, this sensor aims to support reliable engine communication without altering the vehicle’s original design.

Design and testing focus on precision and durability. The sensor emphasizes a stable output that the ECU can interpret consistently, even as air temperature and engine load shift. While outcomes can vary by vehicle and driving style, the part is designed to contribute to steadier idle, smoother throttle response, and steadier performance under stress, rather than guaranteeing any specific improvement.

Key benefits

• Clear, stable signal to the ECU under varying driving demands, aiding accurate airflow readings.
• Fast 15 ms response time with a tight output curve tolerance (< 2%), supporting responsive engine management.
• Durable construction and materials designed to meet OEM specifications for long-term reliability.
