Standard Ignition MAS0474 Mass Air Flow Sensor

Mass Air Flow Sensor for Toyota Mirai

Standard Ignition MAS0474 is a mass air flow sensor for the Toyota Mirai, covering model years 2016-2024. It measures incoming air so the engine control system can calculate fuel delivery and maintain proper drivability, idle quality, and emissions performance.

Key Features

• Mass air flow sensor for emission control applications
• Female connector with one oval connector interface
• 5 male pin terminals for the vehicle harness connection
• Direct fit for Toyota Mirai models from 2016 through 2024
• Standard Ignition MAS0474 for OE-style replacement needs

Detailed Description

Standard Ignition MAS0474 is built for the Toyota Mirai and uses a female, oval connector with 5 male pin terminals for a secure electrical interface. As a mass air flow sensor, it provides the airflow signal the vehicle control system uses to manage air-fuel calculations and related emissions functions. This part cross-references 2-14808 and MA1305 for the same application. If you are replacing a failing Toyota Mirai mass air flow sensor, MAS0474 offers the correct connector layout and fitment for 2016-2024 vehicles.

Common Issues It Can Help Address

• Rough or unstable idle caused by inaccurate airflow readings
• Hesitation or poor throttle response during acceleration
• Check engine light related to airflow sensor performance
• Reduced fuel control accuracy from a worn or contaminated sensor
• Emission control faults tied to incorrect intake air measurement

Installation Notes and Tips

Verify connector shape, terminal count, and harness orientation before installation. Inspect the intake tract for dirt, oil, or leaks that can affect sensor readings, and confirm the replacement matches the Toyota Mirai application by year. For best results, clear diagnostic trouble codes after installation and confirm normal idle and drivability during a road test.

Quality Assurance

Standard Ignition supplies emission control components for service replacement applications, and MAS0474 is built to match the listed Toyota Mirai fitment and connector specifications.
