8 best manufacturers of mass air flow sensors

Review of the best according to the editorial board. On the selection criteria. This material is subjective and does not constitute advertising and does not serve as a purchase guide. Before buying, you need to consult with a specialist.

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.

  1. At idle speed, the engine starts to work uncertainly. These can be increased or decreased, as well as “floating” revolutions.
  2. With a faulty flow meter, there are often problems with starting the engine.
  3. The car loses its acceleration dynamics, while fuel consumption increases.
  4. The smell of unburned gasoline is clearly detected in the exhaust gases.
  5. Spark plug electrodes turn black with soot.
  6. 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.

  1. Loss of performance sometimes occurs due to voltage surges in the on-board network.
  2. 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.

  1. 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.
  2. 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.
