It measures incoming air so the engine control system can calculate fuel delivery and maintain proper drivability, idle quality, and emissions performance.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eMass air flow sensor for emission control applications\u003c\/li\u003e\n\u003cli\u003eFemale connector with one oval connector interface\u003c\/li\u003e\n\u003cli\u003e5 male pin terminals for the vehicle harness connection\u003c\/li\u003e\n\u003cli\u003eDirect fit for Toyota Mirai models from 2016 through 2024\u003c\/li\u003e\n\u003cli\u003eStandard Ignition MAS0474 for OE-style replacement needs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDetailed Description\u003c\/h2\u003e\u003cp\u003eStandard 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.\u003c\/p\u003e\u003ch2\u003eCommon Issues It Can Help Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRough or unstable idle caused by inaccurate airflow readings\u003c\/li\u003e\n\u003cli\u003eHesitation or poor throttle response during acceleration\u003c\/li\u003e\n\u003cli\u003eCheck engine light related to airflow sensor performance\u003c\/li\u003e\n\u003cli\u003eReduced fuel control accuracy from a worn or contaminated sensor\u003c\/li\u003e\n\u003cli\u003eEmission control faults tied to incorrect intake air measurement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify 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.
