OEM Mass Air Flow Sensor (MAF) for 1998-2002 Nissan Pathfinder models equipped with the VG33E powertrain. 

The Mass Air Flow (MAF) Sensor is an important component of a vehicle's engine management system, which measures the amount of air entering the engine to ensure the proper air/fuel ratio. A faulty MAF sensor can cause a range of issues, including poor performance, reduced fuel economy, and even stalling.

Here are some signs that the MAF sensor may need to be replaced:

• Check engine light: If the MAF sensor fails, it can trigger the vehicle's check engine light. A diagnostic scan can identify the cause of the error code, which can often point to the MAF sensor.
• Reduced fuel economy: A malfunctioning MAF sensor can cause the engine to run rich, using more fuel than necessary and leading to reduced fuel economy.
• Engine performance issues: A faulty MAF sensor can cause the engine to run poorly, with symptoms including rough idling, hesitation, and reduced power.
• Stalling or hesitating: A malfunctioning MAF sensor can cause the engine to stall or hesitate during acceleration, making it difficult to drive.
• Dirty or contaminated sensor: Over time, the MAF sensor can become dirty or contaminated, which can cause it to fail. Cleaning the sensor may resolve the issue, but if the sensor is damaged or malfunctioning, it will need to be replaced.

Replace your insufficient Mass Air Flow Sensor with this genuine Nissan replacement.
