Mercedes mass air flow sensor

The Mass Airflow Sensor , MAF , is a key component in the process of the movement of fuel into and through your engine. It measures the amount of air entering the engine airflow. It works by a small, electrically-heated wire positioned next to a temperature sensor. This then determines the amount of fuel to be injected into the engine. A failure of the MAF could primarily cause miscalculations in the amount of fuel injected into your engine, causing serious problems in standard vehicle functions. Because the mass airflow sensor is central to keeping the proper ratio of air-to-fuel in your engine, it is essential to contact a Mercedes professional right away if you notice any symptoms that may point to its failure. Here are a few ways to notice this and the possible effects of a failing MAF. When your Mercedes is running as expected, it is normal to be less attentive to the sounds and vibrations it makes. However, keeping tabs on these behaviors can help you in noticing unusual symptoms like those below. This condition may vary by individual vehicle. When you are at a complete stop and your vehicle feels as if it is gently or even violently rumbling , one of the possible causes is a failing mass airflow sensor. This can also happen when driving at low speeds. Since the mass airflow sensor is essential to standard operating of your engine, any problems or failure of this component will lead to difficulty in starting the engine. The MAF is unable to accurately calculate the appropriate amount of fuel to be injected into the engine and so unable to aid it in ignition.

This information is then used to adjust the ignition timing and fuel injection to optimize engine performance. If the sensor fails, it can result in many issues, including poor fuel efficiency , reduced power output, and even engine stalling. The symptoms of Mercedes mass airflow sensor failure can vary depending on the severity of the issue. Some of the most common symptoms include:. It is important to note that these symptoms can also be caused by other issues with the vehicle. So if you are experiencing any of these symptoms, the best solution is to have your vehicle inspected by a qualified mechanic to ensure that the MAF sensor is the culprit.

The mass air flow sensor or MAF sensor is part of the intake system in Mercedes-Benz GLE responsible for measuring the amount of air entering the engine. Driving your GLE with a bad MAF sensor can damage the engine, so you must act urgently to avoid more expensive repairs. The most common signs of bad mass air flow sensor MAF in Mercedes-Benz GLE are loss of power or slow acceleration, engine hesitation or jerking during acceleration, erratic idling, misfires, poor exhaust emission values and sometimes black smoke comes out of the tailpipe. It is not only important for power delivery in your GLE, but also for the lowest possible pollutant emissions. The optimal amount of fuel can no longer be calculated which results in either too little or too much fuel injected into the combustion chambers. This can cause the engine warning light to illuminate in the instrument cluster and the fault can be read out by a diagnostic device.

The mass air flow MAF sensor measures the mass flow rate of air entering the engine, and this information is used by the engine control module ECM to calculate the amount of fuel needed for the correct air-fuel mixture. Mass air flow sensors are often built into a larger housing that may include a screen to prevent debris to prevent the sensor from becoming contaminated, but can also clog over time and limit airflow. In many cases, MAF sensors that seem to be failing may simply need to be cleaned with a mass air flow sensor-specific solvent to be returned to service.
