BMW X5 E70 2007-2013 3.0d, xDrive Air Flow Meter MAF Sensor

What Is a Mass Air Flow Sensor?

A mass air flow sensor (MAF) is one of the key components of the electronic fuel injection system in your vehicle. It is typically installed between the air filter and the engine intake manifold. The mass air flow sensor measures the amount of air entering the engine, allowing the system to calculate the correct air-to-fuel ratio.

The mass air flow sensor is a precision electronic component that communicates directly with the vehicle’s onboard computer. By accurately measuring incoming air, it enables the engine to regulate performance, fuel delivery, and emissions. Correct operation of the MAF sensor is essential to ensure the engine runs smoothly and efficiently.

Regular maintenance, including timely air filter replacement, can help prolong the life of the MAF sensor and ensure consistent performance. While replacement intervals can vary depending on driving conditions and mileage, a general guideline is to inspect or replace the MAF sensor every 10,000 to 12,000 miles, depending on vehicle usage.
