Mass Air Flow Meter

When buying a car like a Mercedes or a BMW, you are buying a car that is top in its class. If you look at the 2015 Mercedes-Benz C-Class, you will be buying a car with cruise control, front, and rear door pockets, electric power steering, transmission, cruise, and audio controls on the steering wheel and interior air filtration. Technology like Bluetooth wire data links for a hand-free phone service and a pre-collision safety system makes it the perfect family vehicle.

However, all these specifications do mean that the owner should keep to the manufacturer’s scheduled maintenance guidelines. Technology can provide in comfort, but it needs to be maintained. When you do not change the oil and air filters, it can lead to some serious problems that can cause you plenty of discomfort. One component that is affected by a dirty an air filter is the mass air flow sensor.

The Mercedes Mass Air Flow Meter is a mass air flow sensor (MAF) that measures the volume and density of the air that enters the engine. This sensor is a component of the computer controlled engine system (ECU) and found in a plastic casing between the air filter and the engine. When an air filter is blocked, dirty particles enters the engine and dirt can accumulate on the MAF sensor, which reduces its effectiveness.

The reason why a mass air flow sensor is so important is that it sends a signal to the engine computer that uses that measurement to calculate spark timing and the fuel delivery. Most of the sensors use an electrically charged wire to determine the airflow that is entering the air intake. Then the wire based on the airflow produces an electrical voltage and this information is send to the engine.

The information that is produced by the electrical voltage is used to adjust spark timing and advance as well as fuel delivery. If needed, the timing and fuel deliverance is adjusted, but faulty information might lead the car to idle roughly, use more fuel or even to stall. It is therefore of the utmost importance that your car’s Mercedes Mass Air Flow Meter is working correctly and efficiently.

If your MAF sensor is faulty, the Check Engine light or the Service Engine Soon lights may illuminate. Although a mass air flow meter replacement is possible, the fault needs to be identified.
