The Value of a Functional MAF Sensor in Your BMW

by techplusaadmin March 17, 2022

BMW is one of the best choices when it comes to sophisticated cars. It has the best distinctive features, and it’s also the most luxurious car in its section. There are various types of complex technology for assistance systems in a vehicle, and they are installed in different places and have various functions in a car. Many sensors perform important tasks in your BMW. For instance, the Mass AirFlow (MAF) sensor helps to increase the efficiency of your engine, providing the best performance and strengthening fuel economy.

There is no replacement timeframe for the mass airflow sensor. They are usually not replaced until it develops problems or fails. As long as they function correctly, they remain in service indefinitely. It is recommended that you clean your MAF sensor regularly and also change your air filter.

MAF sensors are positioned between the air filter and the throttle body, which measures the amount of air entering the engine. The engine control unit, through the help of the air mass information, the correct fuel mass is balanced and transferred to the engine. The air mass cannot be measured directly, however, the mass flow rate can be determined by the engine’s ECU, through the help of additional sensors and input.

Functional MAF Sensors

In a BMW and other brands of cars, one of the most important factors for sensor performance is precise testing and calibration, which sets the standard apart from the rest. Vane-type hot wire are the two standard types of mass airflow sensors in use on automotive engines.

The vane type of mass airflow sensor ascertains the level of air passed from the engine air with a metering vane in the air brook. The signal voltage is used by the engine control unit to calculate the level of air flowing into the combustion chambers. Road debris and other contaminants that get past the air filter can affect the sensor’s sensing element.

Modern cars like BMW use a hot wire type of airflow sensor. The hot wire airflow meter is the most common MAF sensor. It consists of a heating resistor, intake air temperature sensor, intake air temperature measurement resistor, and control circuit.

A MAF through its performance has the physical capacity to measure a higher air volume which helps in super accurate reading, so your vehicle’s computer will have all the info it needs to take care of that performance engine.

It is important to clean the MAF Sensor anytime you clean the air filter. A clean MAF sensor can restore horsepower, which is significant for just cleaning a sensor. The hot wire MAF reacts very quickly to changes in airflow, responds to temperature changes in the heating elements, it’s durable, and is enhanced by the absence of moving parts, it’s cost-effective and the whole package is smaller. The diagnostic trouble code (DTC) will be displayed if the engine starts while the channel is clogged.

Let Tech Plus Automotive Help You

Our technicians will first try to clean the mass airflow sensor to restore its function, but this rarely brings it to 100% operation and accuracy. Most BMW owners opt to have it replaced to ensure they are getting the most horsepower from their engine possible.

There are instances where the internal circuitry is damaged or shortened. In these cases, the sensor needs to be replaced. If you find yourself needing to replace your MAF sensor, the mechanics at Tech Plus Automotive are happy to help with this task.
