Mass air flow sensor is essential electrical node of a modern car. His task is adjust the air-fuel mixture depending on the load on engine. Most modern flow meters transmit information to an electronic control unit that remembers errors, simplifying the work of the 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 replacement of the DMRV is required, how to choose the right node? Answers to These questions are given by our experts.

About symptoms, causes and choice
Symptoms of a faulty DMRV. There are several signs indicating a malfunction in the flowmeter.
- At idle, the motor begins to work uncertainly. It can be increased or decreased, as well as “floating” speed.
- A faulty flow meter often causes problems with engine start.
- The car loses acceleration dynamics, while increasing consumption fuel.
- In the exhaust gases, the smell of unburned gasoline.
- The spark plug electrodes turn black with soot.
- Sensor malfunction can be signaled by Check lamp Engine
Causes of malfunctions. Experts note several Popular causes of DMRV failure.
- Loss of performance sometimes occurs due to differences voltage in the on-board network.
- The most common cause of a meter failure is pollution. This may be due to a late replacement of air filter. But more often dust and moisture enter the airway through sealing ring. Attempts to clean the inside of the DMRV with various liquids usually lead to the final exit of the node from system.
How to choose a flowmeter? The car owner has several DFID selection options.
- The original spare part is quite expensive, but choose it the easiest way for the make and model of car, engine size, year of manufacture. Also, the seller of the store may ask for the VIN-code of the transport facilities.
- Flowmeters are sold assembled or separately from the tube body. A complete kit is rarely faked, but costs more. To avoid counterfeiting, experts recommend checking if it is knocked out production date on the sensor and flowmeter housing. The second caveat – the original uses fixing screws sensitive element to the body with a five-beam head, and on fakes use 6-beam screws. Some manufacturers counterfeit flowmeters cast two words AIR FLOW on the body without space.
We selected 8 best manufacturers of DMRV in the review. All of them implemented in the Russian car market. When compiling a rating expert opinion and reviews were considered consumers.
