- 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: What’s the BMW E46 mass airflow sensor location?
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 do you install a mass air flow sensor?
A: Install the new mass air flow sensor into the air filter housing. If the o-ring gives you a hard time going in, apply a small amount of dish soap to the o-ring, it will slide right in and the soap will not damage your o-ring. Install the air filter housing into vehicle in reverse order of removal.
Q: Can a mass airflow sensor set a fuel trim fault code?
A: An unmetered air leak downstream of the mass airflow sensor will set codes similar to a faulty mass airflow sensor. When you suspect a mass airflow sensor as the culprit for setting a fuel trim fault code, check when the fault code was set. You can do this using OBD II freeze frame data.
Q: How does the airflow sensor hot film work?
A: Since the airflow sensor hot film monitors the temperature of the passing air, it automatically adjusts for the increased volume (= lower density) of the incoming air. Mass air flow sensors accuracy skews over time and can lead to fault codes or drivability problems. When replacing, inspect the plastic intake air ducts for cracks or dry rot.
