For Nissan Frontier and Nissan Xterra applications, a properly functioning MAF sensor is important for stable idle quality, throttle response, and consistent drivability. This part number, MAS0459, is also a useful reference when comparing replacement options for the same vehicle applications.\u003c\/p\u003e\u003cp\u003eThis part cross-references Beck\/Arnley 158-1606 and Delphi AF10201 for the same application.\u003c\/p\u003e\u003ch2\u003eCommon Issues This Sensor May Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRough idle caused by inaccurate airflow readings\u003c\/li\u003e\n\u003cli\u003eHesitation or stumble during acceleration\u003c\/li\u003e\n\u003cli\u003eCheck engine light related to air metering faults\u003c\/li\u003e\n\u003cli\u003ePoor fuel delivery calculations from a failing sensor\u003c\/li\u003e\n\u003cli\u003eDriveability concerns on Nissan Frontier and Nissan Xterra models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify connector shape, terminal count, and sensor location before installation. Inspect the intake ducting, air filter housing, and wiring connector for contamination or damage, since air leaks and poor electrical contact can affect sensor performance. After installation, clear any stored diagnostic trouble codes and confirm idle quality and throttle response during a road test.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eStandard Ignition supplies emission control sensors for service replacement applications.
