The mass air flow sensor is an integral electrical component of a modern car. Its task is to regulate the air-fuel mixture depending on the load on the engine. Most modern flow meters transmit information to an electronic control unit, which remembers errors, simplifying the work of diagnosticians. The sensor is located immediately behind the air filter, and its durability depends on the purity of the incoming air. That is why it is important to change the filter element in a timely manner. When you need to replace the mass air flow sensor, how to choose the right node? Our experts provide answers to these questions.

About symptoms, causes and choices
Symptoms of a faulty mass air flow sensor. There are several symptoms that indicate a problem with the meter.
- At idle speed, the engine starts to work uncertainly. These can be increased or decreased, as well as “floating” revolutions.
- With a faulty flow meter, there are often problems with starting the engine.
- The car loses its acceleration dynamics, while fuel consumption increases.
- The smell of unburned gasoline is clearly detected in the exhaust gases.
- Spark plug electrodes turn black with soot.
- A sensor malfunction can be signaled by the Check Engine light.
The reasons for the problems. Experts note several popular reasons for the failure of the DMRV.
- Loss of performance sometimes occurs due to voltage surges in the on-board network.
- The most common cause of meter failure is contamination. This may be due to a late replacement of the air filter. More often, however, dust and moisture enter the airway through the O-ring. Attempts to clean the insides of the mass air flow sensor using various fluids usually lead to the final failure of the unit.
How to choose a flow meter? The car owner has several options for choosing the DMRV.
- An original spare part is quite expensive, but it is easiest to choose it according to the make and model of the car, engine size, year of manufacture. Also, the store seller may ask for the VIN code of the vehicle.
- Flowmeters are sold assembled or separately from the tube body. The complete kit is rarely counterfeited, but it costs more. To avoid counterfeiting, experts recommend checking whether the date of manufacture is stamped on the sensing element and the flowmeter body. The second caveat is that the original uses screws to attach the sensing element to the case with a five-beam head, and on fakes, 6-beam screws are used. Some manufacturers of counterfeit flow meters cast two words AIR FLOW on the body without a space.
We have selected 8 best manufacturers of mass air flow sensors for review. All of them are sold in the Russian car market. When compiling the rating, the opinion of the expert community and consumer reviews were taken into account.
Rating of the best manufacturers of DMRV
|Rating of the best manufacturers of DMRV||1||Bosch||5.0|
The recognized leader in the development and production of mass air flow sensors is the German company Bosch. It is this manufacturer who is considered the inventor of a complex electrical device that controls the air flow for the engine power system. The new system was presented to the public in the early 70s of the last century. Modern DMRVs are made using innovative technologies that allow the unit to serve for many years. The experts praised the film-type models, which combine reliability with the highest measurement accuracy. The brand receives the laurels of the winner in our ranking.
Many experienced car owners advise beginners to purchase Bosch flow meters, despite the high price. Subsequently, the purchase will pay off by reducing fuel consumption and long-term operation of the unit.
- Newest technologies;
- high measurement accuracy;
- high price.
The history of the German company Pierburg began in 1909. In those years, the manufacturer supplied steel for the military industry. Today the brand is focused on the production of such critical vehicle components as flow meters, EGR valves, thermostats, pumps, electromagnetic and pneumatic valves. Experts include cooperation with car factories Mercedes, Volkswagen and Opel into the company's asset. In 1998 Pierburg merged with Kolbenschmidt to expand its presence in Europe, the USA and Japan. For the optimal combination of price and quality, the brand becomes the silver medalist of our rating.
On thematic forums, motorists often recommend Pierburg flow meters when it comes to car repair. And only in durability they are inferior to Bosch products.
- high-quality assembly;
- simple construction;
- affordable price.
Siemens has extensive experience in the design and creation of metering devices for gases, steam and liquids. The assortment includes both the simplest indicators and the most complex electronic systems. And if 170 years ago, the German manufacturer collaborated with tram and telegraph lines, then at the moment among the partners are automobile factories, energy concerns and medical institutions. Mass air flow sensors are delivered to the conveyor Opel, which indicates high quality. Experts have appreciated the exceptional accuracy of the instruments, their reliability and durability. The third position in our rating is explained only by a small range of mass air flow sensors.
Russian motorists consider Siemens flow meters to be reliable and durable. But the high price stops many from buying.
- high quality;
- accuracy of measurements;
- high price;
- modest assortment.
The Japanese manufacturer of the DMRV manages to successfully compete in the global automotive electrical market due to its compactness and lightness. Denso has invented the first in-wall flowmeter. According to experts, the strengths of the advanced sensors are their high measurement accuracy and clever design that prevents contamination. The Japanese manufacturer works closely with renowned car factories that use Denso control systems as original components.
The brand stopped one step away from the top three in the rating for high prices and a limited DMRV catalog. That is why domestic motorists do not prefer high-quality Japanese products.
- high accuracy;
- protection against pollution;
- high price;
- limited range.
When a car owner does not have the money to buy a Bosch or Denso flow meter, the choice falls on the products of the Danish company JP Group. The date of foundation of the company is considered to be 1975, when the first spare parts for the chassis of the car were produced. Today the brand cooperates with well-known European car factories Volkswagen and Porsche. The company not only produces a wide range of auto components, but also deals with packaging. Experts point to the combination of affordable price and good quality MAF sensors, making them an enticing alternative to the original product.
The brand ranks fifth in the ranking, since most of the spare parts supplied to the Eastern European market are produced in China. That is why users deservedly criticize short-lived auto parts.
- low price;
- good quality;
- a wide range of;
- high popularity.
In the budget segment of the aftermarket of auto parts, the Polish company Maxgear is confidently taking the lead. Products are sold in European countries and in Russia, the manufacturer encloses DIN and ISO quality certificates. Having entered the TecDoc catalogs, a motorist can find almost any part for his car (with the exception of bodywork). On the one hand, experts note the absence of counterfeits in the domestic market, but on the other hand, the percentage of defects has recently increased from 5 to 9. The brand is in the TOP-6 of our rating for its rich assortment and affordable prices.
In the reviews of motorists, you can find completely opposite judgments. Some consider the quality of auto parts to be decent, others complain about the quick failure of flow meters, CV joints, high-voltage wires.
- low price;
- no fakes;
- a wide range of;
- good quality.
