OEM Mass Air Flow Sensor for 2001-2004 Nissan Pathfinder models equipped with the VQ35DE powertrain.

The Mass Air Flow Sensor (MAF) sensor is a critical component of a vehicle's engine management system. It measures the amount of air entering the engine to ensure the correct air-fuel mixture for efficient combustion. Over time, the MAF sensor can become dirty, contaminated, or damaged, leading to inaccurate readings and potential engine problems.

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

• Check Engine Light: A malfunctioning MAF sensor can trigger the vehicle's check engine light. If the diagnostic trouble code (DTC) indicates a problem with the MAF sensor, it may need to be replaced.
• Decreased engine performance: A faulty MAF sensor can lead to a decrease in engine power, rough idling, hesitation, or overall poor performance. The engine may feel sluggish or experience difficulty accelerating.
• Stalling or rough idle: A worn-out or contaminated MAF sensor may cause the engine to stall or have a rough idle, as it cannot accurately measure the incoming air volume.
• Poor fuel efficiency: A malfunctioning MAF sensor can disrupt the air-fuel mixture, leading to decreased fuel efficiency. If you notice a sudden decrease in gas mileage, the MAF sensor could be a potential culprit.
• Dirty or contaminated sensor: Over time, the MAF sensor can accumulate dirt, debris, or oil, affecting its performance. If cleaning the sensor doesn't improve its function, it may require replacement.
