Anyone existing car in the world is mandatory to equip special systemdesigned to measure speed vehicle and the transfer of this information on the ECU. The carburetor vehicles use a cable (mechanical) Speedometer system, as a result of which the speed sensor is not required here. Therefore, on VAZ 2110, 2111 and 2112, it is mounted only on injection cars - this system electronic and responsible for managing work power aggregate. Replacing the speed sensor - the event is quite time consuming, but not at all difficult. About this further in the article.
Purpose this device - "Establishment" Angle of the Angle of Ignition, Quality Control fuel mixes and proper fuel supply. The sensor collects for injector Engine Mass of information such as motor turnover, detonation level, speed and so on, and transfers to the electronic unit Digital signals. In turn, this data is checked here and appropriate adjustments are made to the operation of the injector. As a rule, the speed sensor is located under the hood, in the motor compartment, near the exhaust manifold.
Signs Speed \u200b\u200bSensor Fault
If the odometer suddenly refuses to work, and the speedometer "lying" relative to kilometer and speed or works by jerks - this indicates the incorrect operation of the speed sensor or drive. Also possible problems in electrocopy, the pinout is confused, brings the connector and so on. In addition, the speed sensor malfunction can also be the fact that the vehicle stalls at idle, but this may be the mass of other reasons. Of course, if the speedometer gives obviously false testimony, and the "Check Engine" lamp burns on the instrument panel, then the reason is the failed speed sensor.

Please note that these verification methods are suitable only for speed sensors using the Hall effect in their work.
Sensor controller, how to purchase a new controller to pay attention to when buying
When choosing a new speed sensor, pay attention to the following points: It is desirable that the connectors inside the blocks have notation - "-", "a", "+", instead of the standard "1," 2 "," 3 ". In fact, it has no fundamental importance, but the pinout will be carried out faster and, most importantly, correctly.
One more important moment - Prefer the device with a metal rod, because it will last for more than six months, "released" plastic. Be sure to check whether the rod was equipped with a puck, as it rotates and does it have a backlash.
Tools, appliances and consumables
- Keys on "21" and "22".
- Transmission oil.
- New controller.
Preparatory work, how to get to the controller and replace it with a new
Wiring pinout, to pay special attention to using the multimeter
We draw attention to the pinout inside the pad. When the ignition is turned on, you determine to which connector is connected to which connector. If you have connected the wire to the plus connector, and the multimeter shows "minus", then it should be urgently changed polarity. Therefore, it is advisable to take a block with the appropriate notation. But if this did not turn out, you can take the usual one. In this case, the pinout is the following - 1 - this is "+", 2 is the "signal output, and 3 is" - ".
At the last stage, do not forget to check the drive, as well as the work of the vehicle as a whole when the wheels are hung or during the movement of the car.
On every car, regardless of its class, manufacturer or country of origin, there is no compulsory system that is responsible for the speed and number of kilometers. Vaz 2110 is no exception. But only on the injection.
Carburetor models apply a cable mechanical system Speedometer works, because the speed sensor is not here. He is simply not needed.
What is it needed for what
Work at the speed sensor is huge. It informs the electronic control unit information about the correct fuel supply, determines and sets the ignition advance angle, is responsible for the quality of the fuel and air mixture.
The sensor collects all sorts of data and transmits them as signals to an electronic control unit. There information is checked, appropriate adjustments are made to the operation of the injection engine.
Signs of malfunction
If the odometer does not work on your car, the speedometer sensor functions with certain jerks, or it gives no corresponding reality data, probably the device has failed.
The problem may be that the connection scheme is broken, disorders are observed in the electrical circuit, the connector does not work. In addition, the challenge of the speed sensor becomes not rarely the problem, which is confused during the assembly process.
An indirect sign of malfunction - the car stalls when working at idle.
You, as a driver, will easily notice the presence of incorrect indicators on the speedometer, and also pay attention to signal lampwhich requires check engine ( Check Engine). If such phenomena is detected, it does not have to doubt - the speed sensor is required.
Search for breakdown
To proceed to troubleshoot the problem, first need to find the device. By photo you can determine how the speed sensor on the VAZ 2110 looks outwardly.
As for its location, look for in the rotor space in the immediate vicinity of the exhaust manifold. Frankly say, the place where it is installed, you can not call any ideal. It's all about the collector. During the car, the collector heats up. Wires of the sensor rubs about it, which over time leads to malfunctions, short circuit.
And how to check the speed sensor on the VAZ 2110 car? First of all, visually. Be sure to make sure that the cable was not occurred. Often problems with the device arise exactly because of it.
After checking the device visually, and without determining the presence of breakage, it tells us about the malfunction of the element itself. Such a problem is solved by replacing it.
Preparatory activities
The competent replacement of the speed sensor on the VAZ 2110 implies the obligatory purchase of a new device that meets all the requirements of your car.
In fact, when purchasing a device, adhere to two basic rules.
- Choose the sensor, the connectors inside the pads of which are indicated -, and +. Usually there is an designation 1.2 and 3. There is no fundamental difference between them, it is easy to perform a pickup, it will be much easier precisely with such marking. It is an incorrect connection that becomes often the cause of what you have to seek help at the station maintenance. And this is completely different financial costs.
- The rod on the element must be made of metal. If the rod plastic, it will last you for about 6 months. Not in your interests regularly replace. But do not forget to check the metal rod, proper rotation, as well as the presence of washers in the configuration.
Replacement
Now to the question of how to replace. To do this, we dismantle the old device and plug in its place new. Step by step your actions look like this:
- Remove the minus wire with rechargeable batterythat will allow making a car;
- Now turn off the wires from the sensor and remember, in what form there was a pinout;
- Removes the device with a simple twisting hand. No tools are usually used. But if the device sits tightly, then use keys by 22 or 21 millimeters. Depending on the modification of your "dozens", the design of the sensor may differ slightly;
- In parallel we advise you to check the wiring;
- After removing the meter, unscrew the locking nut on which the wire holds on the transmission transmission box;
- Remove carefully so as not to drop the rod into the box. If this happens, you will have to fully disassemble the checkpoint. This is clearly not in your interest;
- A new device with a rubber ring must be lubricated transmission fluidso that fixing in a new place turned out to be as reliable as possible;
- The assembly is performed in the reverse order;
- Pay special attention to the pinout. Connect the multimeter by turning on the ignition. If the device has shown "minus", then you have connected the wire to plus, which cannot be categorically made. That is why we initially advised to use the sensor, which does not have the designation 1, 2 and 3.
If you avoid the use of a new device with uncomfortable marking 1, 2 and 3, then you failed to remember the important detail of the pinout:
- 1 corresponds to "+";
- 2 indicates the signal output;
- 3 is "-".
After replacing the item, do not forget to check the device in action. To do this, you can reduce the front wheels, or just ride by car in the area. If the speedometer and odometer show the correct information, you can read the work performed with your own hands.
The VAZ 2110 speed sensor is an important element of the electronic engine control system, therefore, it is possible to meet it only on the injection "dozens".
Where is the speed sensor on the VAZ 2110?
In the "dozen" speed sensor is located on the gearbox.
If more detailed, it follows it in the open space, in motor compartment, Next to the outlet collector - between the flexible shaft and the speedometer drive. The sensor is set vertically.
Principle of operation.
The principle of the speed sensor of the VAZ 2110 is based on the Hall effect: transmitting electrical pulses (in the VAZ brand cars, by the way, only 6 such pulses are used) in the ECU, the sensor informs the one about the speed of rotation of the leading rink of the machine, on the basis of which the control unit does not simply affect on the speedometer arrow / kilometer reading, but also controls the engine operation, sending the required signals to the regulator idle move and the throttle position sensor.
When do you need diagnostics?
Due to a limited number of impulses and for many other reasons (motor oil, dirt came to the sensor, the contacts or wires located near the speed sensor were oxidized, there are mechanical damage to the part and other) in the "dozens" can often observe flaws in the work Speedometer or its complete inoperability. Simultaneously with this, most often, problems occur when driving on idle turns and turn on the "Check" system lamp (error code "24"). Be that as it may, any of the names of the signs require from the car owner of the mandatory diagnostics of the speed sensor, because the causes of faults can be covered in it, and can be completely different.
How to check the speed sensor VAZ 2110?
There are only 3 ways to check the "dozens" speed sensor. One of them implies use control lamp, Two others are based on the scheme.
But before switching to any of them, make sure that there is grounding and voltage on the contacts, to do this, disconnect the electrical connector from the sensor, simply squeezing the "mustache" and remove the chip, and each of them. One of the contacts should show the voltage of 12V.
If everything is in order with the power, go directly to the diagnosis itself.
Method number 1 is carried out according to the above scheme without removing the sensor from the car.
- Subject the front wheels.
- With the help of regular wires (if you have an assistant) or with the "crocodile" clamps (if you do not have an assistant), connect the voltmeter to the speed sensor, without forgetting the current to it.
- Install the PPC to the transmission position and turn the wheel.
- If everything is in order with the sensor, in response to these actions, you will see changes in the pulse contact voltage - between the output and mass - more speed, the greater the voltage. Range of changes 0.5-10V.
Method number 2 is carried out according to the above scheme on the removed from the car the sensor.
- Remove the speed sensor (how to do it, will be described in detail below - in the instructions for replacing it).
- Using wires, again repeat the above scheme.
- Take the tube, passatati or any other prior art that allows you to scroll through the axis of the sensor (here, the main thing, do not forget about the safety technique), and rotate the sensor around its axis.
- The indications of the multimeter (from 0.5V to 10V) will indicate that everything is in order with the sensor.
Method number 3 - "Verification of a light bulb".
Applies to speed sensor without removal from the car.
- Using a jack leading wheels lift on the ground.
- According to the diagram, connect the light bulb to the diagnosed element.
- Put the gearbox on 5 transmission and brighten the wheel. The light bulb will have to freeze. If this does not happen (if there is a voltage in the network, naturally), the sensor should be replaced.
Replacing the speed sensor VAZ 2110: detailed instructions for action.
- Pre-de-energized the car (removing the wire with the minus terminal of the AKB), squeeze the arms on the sides of the sensor to the center, and disconnect the wire block from it.
- Remove the speed sensor, simply twisting it counterclockwise (with hands or with the key to "21", and install a new one.
- Tighten the sensor until it stops, attach the wire block to it, observing the polarity.
Be careful! In the process of such, it would seem that there would be a very high probability of damage to the drive rod and hitting his debris inside the drive.
If it is still possible to avoid it, act as follows:
- unscrew the mounting of the speedometer (nut with a washer) key to "10";
- let's try to pull it out on yourself if it does not work - help yourself with a cape key on "14", most importantly, do not relieve the rod, otherwise you will have to disassemble all the CAT;
- further actions depend on good luck and your desire. You can simply replace the stock (when buying, be sure to compare its marking with the detail failed, since the number of teeth on the gear can be different), but you can still try to remove the debris, especially if it is plastic: split the wire on fire and pour it the fragment , Wait for the wire cool and remove it along with plastic. If smaller items remained inside, you can try to flick with seed or scissors, in case of failure - the rod changes.
Important! The new rubber seal before installing is missing motor Oil, and the rod itself is a red sealant, because in the drive, it is no longer fixed.
Video.
Any car is equipped with a system that shows the speed of movement and a kilometer (traveled distance). It is a speedometer that is a device to determine instant speed, makes it possible to find out what maximum speed VAZ 2110.
Speed \u200b\u200bsensors are installed only in injection vehicles, where carburetor engines are present, they are not. This device is responsible for feeding and fuel consumption, an angle of the ignition advance, and monitors the quality of the combustible mixture. All data is transmitted to the electronic control unit, which is under the control of the injector.
Before the appearance of sensors, each carburetor Engine Mechanical speedometer drives were installed. On VAZ 2010 cars issued until 2006, mechanical drives are installed. Newer cars released after 2006 are equipped with electronic sensors.
Speed \u200b\u200bSensor VAZ 2110 16 valves Signs of malfunction
Breakdowns can manifest:
- the presence of interruptions in work, false data in the instrument readings to determine the speed and measurement of the number of rotational speeds;
- lack of sustainable engine operation at idle;
- turning Check Engine (Check engine) on the dashboard;
- the termination of the issuance of errors about the absence or interruption of the sensor signals (P0500 and P0503) by the computer.
These problems arise for various reasons: the sensor connectors contaminated, the contact or the integrity of the wire connecting the computer with the sensor was disturbed.
Always need replacement
The information transmitted by the speed sensor to the ECU is very important, it is from her who depend on the instruments that were discussed above. Also, this information affects the quality of the fuel mixture, which is supplied to the cylinders, the frequency of revolutions at idle turns, the stability of the engine and the amount of fuel consumed.
If the sensor malfunction, the electronic unit is not able to determine, is a car in motion, or stands. At the same time there are floating momentum, the engine begins to stupn, and the fuel consumption will be much more.
Conducting DS inspection Available to each motorist. To find a malfunction, you need to know where it is located in the VAZ-2110. The sensor is placed in the engine compartment under the hood, in the engine compartment. Nearby is the exhaust manifold (and on the VAZ-2112 16 valves it is located at the top of the gearbox, is completely visible and is available from the windscreen space).
Wires rub about the collector, and it can cause damage. Sometimes it is sufficient to isolate them and position it so that there is no contact with the collector.
Do not forget about the climb of the cable capable of becoming the cause of breakage. If there is no such problem, it means that it is necessary to search for it in the sensor itself or in its drive.
For successful replacement of the VAZ-2110 speed sensor, the speedometer's performance is first restored.
How much is changing
In the case when the wiring and contacts are in order, the sensor replacement is necessary. Its value varies from 170 to 400 rubles. The replacement will also take a bit, from 100 to 150.
To buy you need to know the sensor numbers in the directory. Number 2110-3843010F corresponds to a mechanical drive sensor, and number 2170-3843010 - electronic. It is advisable to choose sensors with the designations "-", "A", "+", and not 1, 2, 3, it will help to make a pinout more quickly. It is necessary to pay attention to the manufacturer not to purchase a low-quality product. The drive must be completely metallic.
Step-by-step replacement of the VAZ-2110 speed sensor for 8 and 16 valves
In order to change the speed sensor yourself, it is enough to have two or three keys at hand (10, 21, 22) and a crusader.
- Turns off the current on the machine, for this, the connector is removed from the battery.
- From the sensor is disconnected by the connector of the wires, at which it is recommended to remember the pinout.
- The sensor can be unscrewed manually, or using keys 21 or 22 (depending on the design).
- The condition of the drive is studied. After the sensor is removed, the nut is unscrewed using the key to 10, which the sensor drive is mounted.
- Replacement is subject to drive with mechanical damageIf there are no, you can leave the former.
- Installing a new device should be made in reverse order.
- On a new drive installed a rubber nozzle that you want to lubricate with transmission oil.
- After installation, it is recommended to check the polarity of the wires using a multimeter. If the contacts suddenly were confused, they change them in places.
- It remains to check. It is done either when the car is founded, or with suspended wheels.
Replacing the electronic sensor
The on-board chain is de-energized, the clamp weakens and the corrugations are removed. Then disconnect the wires from the speed sensor and the latch is moved. Next, with the key on 10, the nut is unscrewed, which the sensor is attached.
The old sensor is replaced by the new sensor, the nut is twisted, the corrugation is connected, the mass terminal is connected.
After that, the engine should start working in the usual mode, which means that the replacement of the VAZ 2110 speed sensor has passed successfully, and normal work Devices resumed.
