BMW Mass Air Sensor & Air Flow Meters

The Manifold Absolute Pressure (MAP) sensor plays a critical role in engine performance by providing essential data to the engine control unit (ECU). This data helps the ECU determine the optimal fuel curve for efficient combustion. A faulty MAP sensor can lead to improper fuel delivery, causing the engine to run rich or lean and resulting in reduced performance or drivability issues.

Replace your MAP sensor with this high-quality unit to ensure your engine operates at its full potential.

Note for N54 applications: An adapter harness (ES#3969322) is required. This TMAP sensor is ideal for high-boost setups commonly used with the N54 engine platform.

The Manifold Absolute Pressure sensor provides pressure information to the engine control unit to calculate air density for determining the engine’s air mass flow rate. A faulty MAP sensor can upset the fuel mixture and ignition timing, causing a surge, rough idle, and a rich fuel condition which can lead to spark plug fouling and a loss of power and fuel economy.

This is a high quality replacment OEM VDO Mass Air Sensor.The MAF controls the amount of fuel that goes through the injectors based on the volume of air coming through the intake. If your vehicle is giving you a MAF code, replace it immediately to ensure you get the best gas mileage and performance. It is common for this part to fail slowly and cause poor fuel mileage and hampered performance. When it fails completely, the vehicle will stutter and stall as it falls into a limp mode. One way to check if your MAF is bad is to unplug the connector before starting your car. If it idles well (compared to a previous poor idle), your MAF needs replaced. If you let this maintenance part go, your fuel economy will suffer as too much fuel is going into the engine and not being burned. A great way to give your vehicle an efficiency boost.
