Function: A mass air flow sensor calculates the oxygen flowing to your engine for the ideal air-to-fuel ratio and helps to increase engine efficiency by doing so. The engine throttle opens when you press on the gas, allowing more air to flow around the hot wire. An electronic chip and PCM work with the airflow signal to calculate how much fuel needs to be injected. This measurement helps keep the air to fuel ratio at the optimal level and gas mileage at as bay.
Features: Precision manufactured and assembled sensing elements are used to accurately measure air flow and restore a vehicle's original drivability; Qualified equipment and state-of-the-art testing, coupled with 100% rigorous quality inspection, ensures an impeccable customer experience; Fast response time and durability; Lightweight and portable, easy to install and clean, and directly replaceable.

FAQ:

Q: How does the BMW E46 mass air flow system work?

A: The BMW E46 digital engine management (DME) systems use a hot-film mass airflow sensor, installed between the air filter housing and the intake manifold, to monitor air flow into the engine intake. Inside the sensor, there is a thin metal film, which is maintained at a constant temperature via electrical current from the ECM.

Q: How does a mass air flow sensor work?

A: Inside the sensor, there is a thin metal film, which is maintained at a constant temperature via electrical current from the ECM. As ambient air flows over the film, it is cooled down and additional current is needed to maintain its constant temperature.

Q: When to use mass air flow fault code?

A: You can do this using OBD II freeze frame data. Normally, a vacuum leak would set a fuel trim fault code at idle or very low engine RPMs. A mass airflow meter would usually set a fault code when you are driving, or at a higher RPM.
