New DMRV Bosch. What is the air flow sensor to put instead of the failed? External sensor inspection

DMRV Bosch 116 or a mass flow sensor is a regulator designed to control the volume of air that enters the motor. This controller is one of the elements of electronic motor control systems with fuel injection. In the article we will try to answer the question than the models 116 and 037 are distinguished.

Characteristic

On VAZ cars, the air flow sensor is mounted between the air filtering element and the throttle hose. Today, products from the Bosch manufacturer are very popular among compatriots. Regardless of whether the universal is a Bosch sensor or, for example, spark plugs, quality from the German manufacturer can always give odds of domestic products. Consider the main characteristics of the regulators of models 116 and 037.

116

DMRV 116 is designed to control and convert the air flow, which comes into the motor, into the voltage. The data that transmits the regulator make it possible to determine the mode of operation of the power unit and calculate the cycle filling of cylinders by air flow. This filling is carried out on the steady modes of the operation of the motor, which in their duration make up not more than 0.1 seconds.

Consider technical featureswhich possessed DMRV Bosch 0 280 218 116:

• the regulator works on the principle of measuring air flow;
• the device issues the exact data, which ensures optimal fuel consumption;
• the operating range varies from 8 to 550 kg / h;
• the level of the output pulse at the measurement of the range from 0 to 100% will be about 0.05-5 volts;
• as for nutrition, the controller is powered by a vehicle electrical power system, that is, 12 volts it is enough;
• the current consumption indicator is about 0.5 amps;
• the regulator can function normally in the operating range from 45 degrees of frost to 120 heat;
• the resource of the DMRV Bosch 116 is about 3 thousand hours.

037

As for DMRV 037 from Bosch, the technical features will be similar. The controller consists of two main elements - a working and control, as well as a heating resistor device. The air that falls into the engine is cooled by one of the controllers, while the electronic module transforms the difference between temperature regulators. In the event that the sensor 280 218 037 fails, its options will perform DPDZ.

As mentioned above, the technical features of the models are the same:

• the operating range for normal operation varies in the area of \u200b\u200b8-550 kg / h;
• in proper operation, the controller will issue accurate data, making it possible to achieve optimal gasoline consumption (of course, if the engine is operating in normal mode);
• since the element is used in the car, it is logical that it should eat from 12 volts;
• the controller consumes about 0.5 amp of the current;
• the item can normally work as at 45 degrees of frost and at 120 degrees of heat, this is its working range;
• the service life is at least 3 thousand hours;
• in contrast to the model 116, the new DMRV 037 during calculations may produce an error, which is 2.5 percent (both in smaller and to the most side).

What is the difference between the sensors 037 and 116?

What may differ among themselves regulators of these models and is it possible to install 116 instead of 037? There are differences between these controllers, and the case is not in the PMRV pinout. After all, if these models were the same, what's the point would give them different names?

So, what differ controllers between themselves and is it possible to install a model 116 instead of 037:

1. The first difference, which can be guessing on the basis of technical characteristics - This is what model 037 can issue data with an error. Of course, the error in 2.5% is not critical, but it takes place.
2. The device 037 is intended for installation in cars VAZ 2111, 2112, 2123, 21214, which are equipped with controllers M 1.5.4, January 5.1-5.1.3, etc.
3. As for the model 116, its use is relevant in Ladakh 21114, 21124, 21214. Installing this device is allowed on viburnum and priors. The installation of the device is allowed on the car, equipped with controllers M 7.9.7 and January 7.2.

If you collided with the problem of the disability of the device, then when replacing you need to put such a model that has already been installed. But it should be borne in mind that 037 is not a common option, like 116, so finding it more difficult. The latter, in turn, is more common, and its cost below.

The replacement is allowed, but specialists do not recommend this. All because among themselves these devices differ in their tariff, so in the event of a replacement you have to change the control unit parameters. And you can climb into the brains only if you understand what you need to do, and there is a minimum experience.

Bosch air consumption sensor with number 0 280 218 037 is used in air intake systems in the cylinders in the following cars:

Lada Kalina Sedan (1118) 1.6 82 hp Gasoline 2004 - Naz. time

Lada Kalina Universal (1117) 1.6 82 hp Gasoline 2004 - Naz. time

Lada Kalina Hatchback (1119) 1.6 82 hp Gasoline 2004 - Naz. time

In the factory original spare parts catalogs, Lada takes place under its number: 21083-1130010-10 and is its complete analogue.

Typically, the primary signs are not a health of the air flow sensor manifest themselves on an immentable engine, frequently float speeds, it makes it difficult to get cold, sometimes not an adequate reaction and jerking when the gas pedal is pressed. But we recommend referring to specialists to identify malfunction, often these symptoms are characteristic not only for not working air flow sensor. However, any less experienced master will be able to diagnose without any problems.

So, often our customers face a question, is it possible to clean the air flow sensor 0280218037 Bosch, in principle cleaning is useful, do not forget that it is not difficult to finish it and it does not save you from problems if the sensor is completely dead. On our experience we can advise to measure the level of wear of the DMRV. It is necessary when the ignition is turned on, check the ADC, the voltage value of the new DMRV in the Volta region 1.0. If the flow meter gives 1.04-1.05, it can be safely thrown into the garbage, he has already worked his own. If 1.03 it is quite enough for some more short time.

Air Flow Sensor (DMRV) HFM5

Check Concept
To improve the diagnosis and competent examination of faulty DMRV HFM5, the test concept was expanded and a more informative directory of damaged products was developed. Before removing / replacing the DMRV, the sensor is checked below the sequence below.

1. Diagnostics on a / m using KTS 5XX / 6XX.
The extended diagnosis of A / m implies a comparison of the regulatory and actual magnitudes of the mass of air. In this section, the HFM5 diagnostics section is diagnosed directly on the A / m. If the actual values \u200b\u200bare outside the tolerance, the DMRV must be replaced.
More detailed information for the diagnosed A / m can be borrowed from ESI software.

2. Conduct an extended check of the already taken from the HFM5 a / m using a multimeter.

Required devices:
- Rechargeable battery or power supply (12V / 3A)
- digital multimeter
- Check cable (with voltage stabilizer chip)
- A microscope with a tenfold increase (type MBS-10)
- Screwdriver type "asterisk"

Description of verification

Using a check cable with an integrated stress-stabilizer, * 5V voltage is created at the output 4 of the DMRV plug.

* A check cable with an integrated-stabilizer integrated microcircuit can be made on its own or purchased in the trading network (international index 7805, domestic analog - roll5).

The arrangement of the findings of DMRV HFM5:
1. Inbound air temperature sensor
2. 12V supply voltage (red wire)
3. Mass (black wire)
4. Support voltage 5V (yellow wire)
5. Measured signal (+) (blue wire)

Check
1. Static
Connect, observing polarity, check cable 0 986 610 129 to the HFM5 connector as follows:
red wire to power source (+)
black wire to power source (-)
blue wire to multimeter (+)
black wire to multimeter (-)

To eliminate the movement of air in the sensor measuring channel, close the input and output cross section of the DMRV case with plastic covers (included in the delivery).
Using the power supply to submit voltage (12V) on HFM5. Through the voltage stabilizer chip in the test cable, the reference voltage (5V) is created, which is summarized to the output 4.

Regulatory voltage value of 0.98 - 1.02V
If the actual value of the voltage measured is out of admission, with a high probability, you can talk about DMRV contamination. Pollution leads to a violation of HFM5 characteristics, followed by its failure.

Additional information is in the catalog of damaged products.

2. When air supply
Cable connection circuit is the same. It is necessary to create air flow and direct it in HFM5 according to the direction indicated on the DMRV housing. When changing the intensity of the air flow, the measured voltage should increase. If the voltage does not change, the sensor membrane is damaged.
This means: DMRV is faulty.
Conversely, the DMRV is considered good if the voltage changes.
The maximum value can reach 4.5V (depending on the diameter of the sensor and the mass of undergoing air).

3. Check the incoming air temperature sensor (if available)
Blue Banana Checker Cable Plug 0 986 610 129 Connect with an HFM5 plug output. With this plug, the resistance of the air temperature sensor between the output 1 and the output 3 (mass) is measured.
At the end of the telegram, a list of DMRV HFM5 with air temperature sensors are given.

The measured actual value should lie within the limits of the above standards.
Note: With this test, HFM5 without air temperature sensor, the result will be infinite (∞) a large value of the resistance.

4. Visual check. Use the directory of damaged products.
In addition to the above diagnostics, a visual inspection can be performed. The following photos show typical cases of contaminated DMRV or sensors subject to third-party exposure.

Traces of moisture

Oil hit

Alien particles

With significant implities of the HFM5 sensor, the guarantees are not considered. In some cases, the car must be tested for air filter contamination, filter box and nozzle between the filter and DMRV.

Note:
Before installing the new DMRV, it is necessary to remove dust, dirt from the air filter box, install a new air filter and clear the nozzle between the filter and the sensor. Flowing by air under the pressure of the filter box and the nozzle is prohibited, for this it is necessary to use a soft dry tissue.

Third party intervention. C.

the distinguishing element is not fixed or replaced:
Special screws "Star" weakened by no original screws.

Attempt to turn screws. Screw slots are broken.

Sourid intervention in the DMRV device, namely the unscrewing of the rtlessness of the "asterisk" screws, as well as the replacement of the sensing element is prohibited.

4. Disassembling the mass flow sensor.
Screwdriver type "Asterisk" unscrew the screws that fix the sensitive element in the DMRV housing.

Remove the element from the housing. Remove the hermetic ring from the hybrid fee cover.

Open the lid of the underwater channel in the area of \u200b\u200bthe resistive sensor.

Place the sensor under the microscope. Use a microscope with a 10-fold increase.

It should be distinguished:

Dear buyers, to avoid errors when sending a mass flow sensor (DMRV), in the "Comment" line, specify the model of your car, year of release and number of valves.

Air Flow Sensor (DMRV) 037 " Bosch " - thermoenemometric type.

Constructively this type of sensors It has a sensitive element, a thin mesh (membrane) based on silicon, which is installed in the flow of suction air. On the grid there is a heating resistor and two temperature sensors, which are installed before and after the heating resistor.

The DMRV output signal is a DC voltage within 1 ... 5 V. The value depends on the amount of air passing through the sensor. While the engine is running, the air is cooled by a portion of the mesh located in front of the heating resistor. The temperature sensor located in front of the resistor is cooled, and the sensor located behind the heating resistor retains its temperature due to air heating. The differential signal of both sensors makes it possible to obtain a characteristic curve depending on the magnitude of the air flow.

The computer analyzes the DMRV signal and using its data tables determines the duration of the opening of the nozzles, which corresponds to the mass flow signal.

DMRV 037. " Bosch " It has a built-in air temperature sensor (DTV) of which are used in the system of distributed fuel injection of the car 2112 and fuel injection systems under the euro-2 toxicity. Sensitive element DTV is a thermistor (a resistor that changes resistance depending on temperature) - installed in the flow of undergoing air. The controller supplies a voltage of 5V through a resistor with a constant resistance that is inside the controller. The temperature controller calculates the voltage drop on the sensor. With increasing temperature, the voltage decreases. The controller according to the sensor readings calculates the duration of the opening of the nozzles.

DMRV is installed between the air filter and throttle.

To ensure compliance with the requirements of legislation on the number of harmful emissions and to avoid excessive consumption of fuel, air and gasoline must be supplied to the engine in accurately measured proportions. This is carried out using a mass flow sensor of air or a surround sensor that determines the exact amount of air entering the air and transmits this data into the engine control system.

When, as a result of the fuel crisis of the 1972-73 years, the reduction in the fuel consumed was the most important purpose of developing technology, Bosch introduced the air flow measurement system with the K-Jetronic mechanical injection and the L-Jetronic gasoline injection system with electronic control. As Bosch's inventor is still a leader in the development of technologies for measuring volumetric and mass flow of air.
