The mass air flow (MAF) sensor, part of your vehicle's electronic fuel injection system, is responsible for calculating the total amount of air entering the engine. A faulty MAF sensor can cause your vehicle to run too rich or run too lean. You'll notice if the tailpipes eject black smoke or when the engine runs rough or backfires.

A severe reduction in air flow can also trigger mass air flow and mass absolute pressure sensor errors.These sensors are calibrated to deliver signals within predefined ranges. An out of range air flow reading will usually trigger an engine management light to let you know that something is wrong with the sensor or in some …

As dirt and debris gets trapped by the filter, there is less space for air to pass through, causing the pressure drop to rise throughout the filter's life. This one of the main reasons why it is so important to check, change, and clean your air filter every month to help ensure your air filter's pressure drop does not get too high and cause ...

2. How the MAF Works. Before we jump into the diagnostic, let's take a look at how the MAF sensor works so the procedure makes sense to you. Basically, the MAF sensor measures the amount of air flowing into the engine through the air cleaner assembly, which contains the air filter and connects to the throttle body.

When the engine is running as it should, you should hear a familiar hum coming from the motor. However, when the filter becomes clogged, a lack of airflow can cause some strange sounds. In some cases, you might hear a sputtering noise or a popping sound. It's also possible to hear a whistling noise due to the obstructed airflow.

Additionally, unlike sportscars and touring cars, Formula 1 is an open-wheel concept and thus requires the management of tyre wake. This is a very turbulent and destructive air flow, so it is often pushed away from the car. But this wake left behind by the lead car further exasperates the problem of dirty air for the vehicle that is following.

The mass air flow sensor measures the amount of air that enters the engine. The most prominent symptoms of a bad mass air flow sensor include rough running and misfiring, poor acceleration and stalling, and reduced fuel economy. If your mass air flow sensor is faulty, your best courses of action would be to clean it or replace it entirely.
