• Mass air flow sensor for engine air measurement
• Female connector with square housing
• 1 connector, 3 blade terminals
• Fits 1998-2004 Nissan Frontier
• Fits 2000-2004 Nissan Xterra

Detailed Product Overview

The Standard Ignition MAS0459 is used to measure incoming air so the engine control system can calculate fuel delivery more accurately. 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.

This part cross-references Beck/Arnley 158-1606 and Delphi AF10201 for the same application.

Common Issues This Sensor May Address

• Rough idle caused by inaccurate airflow readings
• Hesitation or stumble during acceleration
• Check engine light related to air metering faults
• Poor fuel delivery calculations from a failing sensor
• Driveability concerns on Nissan Frontier and Nissan Xterra models

Installation Notes and Tips

Verify 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.

Quality Assurance

Standard Ignition supplies emission control sensors for service replacement applications. MAS0459 is built to match the listed connector and terminal configuration for the confirmed Nissan Frontier and Nissan Xterra fitments.
