The speed sensor (abbreviated as DS or DSA) is installed on all modern cars and serves to measure the speed of the car and transfer this information to the computer.

How to replace the speed sensor (DS)

First of all, you need to turn off the engine, cool it and de-energize the system by removing the battery terminals. This is very important to avoid injury during repair work;
if there are parts that impede access to the detector, they must be disconnected. But, as a rule, this device is in stock;
the cable block is disconnected from the DC;
after which the device itself is directly disassembled. Depending on the brand of the machine and the type of sensor, it can be fastened with threads or latches;
a new sensor is installed in place of the faulty sensor;
the system is assembled in the reverse order;
it remains to start the car and make sure that the new device is working. To do this, it’s enough to drive a little: if the speedometer readings correspond to the real speed, then the repair was carried out correctly.

When buying a DS, it is necessary to strictly observe the brand of the device in order to install exactly the sensor model that will work correctly. For some of them you can find analogues, but you need to carefully study each of them to make sure they are interchangeable.

The process of replacing the detector itself is not complicated, but if you do not know how to replace it, or if a novice motorist has a problem, you should contact a service station and entrust your car to specialists.

In any case, before starting to repair a car, you should carefully study the instructions and manuals, as well as strictly follow the recommendations and schemes described in the manuals.

Signs of a malfunctioning speed sensor

The most common sign that a speed sensor has failed is idle problems. If the car stalls at idle (when shifting gears or coasting), among other things, be sure to check the speed sensor. Another sign that the speed sensor isn't working is a speedometer that doesn't work at all or doesn't work properly.

Most often, the problem is an open circuit, so the first step is to visually inspect the speed sensor and its contacts. If there are traces of corrosion or dirt, they must be removed, the contacts cleaned and Litol applied to them.

Checking the speed sensor can be done in two ways: with the removal of the DSA and without it. In both cases, a voltmeter will be required to check and diagnose the speed sensor.

The first way to check the speed sensor:

remove speed sensor
determine which terminal is responsible for what (the sensor has three terminals in total: ground, voltage, pulse signal),
connect the input contact of the voltmeter to the pulse signal terminal, ground the second contact of the voltmeter to a metal part of the engine or car body,
when the speed sensor rotates (for this you can throw a piece of pipe on the sensor shaft), the voltage and frequency on the voltmeter should increase.

The second way to check the speed sensor:

raise the car so that one wheel does not touch the ground,
connect the contacts of the voltmeter to the sensor in the same way as described above,
spin the raised wheel and control the change in voltage and frequency.

Please note that these test methods are only suitable for a speed sensor that uses the Hall effect in operation.

Gas speed sensor 3309 where is it

Almost any tachograph installation office will replace your mechanical speedometer with an electronic yes. But the cost of this service will be inadequate. By the way, the office closest to me puts a tachograph for almost 40 sput. Another 9 laps will change the speedometer. No, better by yourself.

A bit unpleasant: there are speedometers, speed sensors. I don't know which speedometer will suit me and which speed sensor it will work with. Speedometer connection diagrams - they are not on the Internet. Meanwhile, the replacement of a mechanical speedometer has a very rational grain: there will be no speedometer cable that freezes in winter and jams throughout the year. The new speedometers have a normal human backlight, in which you can see the speed readings at night and the high beam indicator is much more noticeable.

The speedometer for the jeep should be 24 volts, the diameter of its body is 100 mm.

From my experience it became clear that the speedometer must be adjustable; It will also come in handy, because if I ever change to a different wheel size, the speedometer reading can be corrected. Further investigation gave another criterion: the speedometer should not be with a CAN bus. There was this rubber on gas, there is nothing to start with. That is, it is possible, but for a speedometer with a CAN bus, there is only one sensor, the connection diagram for which is not easy to find. At the same time, the tachograph can work with almost any speed sensor, and if you have a truck with ABS, then you can do without a speed sensor: take a signal from the ABS sensor of one of the wheels.

Having picked up on the Internet, he gave catalog numbers of speedometers compatible with ANZHS.453892.006 (84.3802.000-01) - for GAZ 4795 Optimus, from which he chose the product of Vladimir Avtoribor 87.3802 - mainly due to the fact that he is more common on sale and he has a friend me on the old Forester red arrow with a green scale. It is also customizable, and, valuablely, its instruction manual is posted on the Internet. Everything you need is there: how to connect, how to reassign.

Speed sensors with their abundance and lack of technical documentation caused a stir. I even strangled my personal toad and bought a few more than I needed for experiments. The first batch consisted of inexpensive sensors in a plastic case. Those in the photo give 6 pulses per revolution, so it looks like the speedometer is set initially.

It quickly became clear that they were all implemented with the participation of a Hall sensor, that the circuits may not be the same for different types of sensors, but they all work when connected to a 12-volt or 8-volt power supply, the one that produces the speedometer. The main selection criterion, perhaps, is the sensor connector. The one on the left in the picture is better not to take, I did not find the connecting part of the connector on sale. Otherwise, the connector, which is known for the carburetor eight, its “mother” can be found in stores or in China. Also, if you take the sensor 2111.3843, its contacts are signed on the +A- connector. Driving on the track after that becomes an easy task.

Plastic sensors are not bad, but they have one drawback: they cannot be screwed into the place where the flexible shaft of the speedometer drive is fastened; the sensors have a 16x1,5 thread, the counterpart on the transfer case is 20x1,5. But if you can't screw up, maybe you can screw up? We take a 20x1,5 nut, straighten the edges of the speed sensor hexagon and screw it into the nut, trying, if possible, to do it coaxially. A slight distortion of parts is not very critical, but not particularly desirable. Then cut 7mm of thread on the sensor and screw it back onto the nut. Tighten the nut instead of the speedometer cable. Everything will be fine, the turnover there is small.

Winding a tachograph or winding a speedometer is often necessary for drivers, companies that work where fuel and lubricants are compensated by the norms of a certain fuel consumption per kilometer, unfortunately. But, on the road, this does not always allow you to correctly calculate the real consumption, and in the end, the driver will have to pay for part of the fuel out of his own pocket, since fuel consumption when driving in traffic jams is much higher than usual. To prove something, the employer actually used up more fuel and lubricants, it's simply useless than it should be decided by the rules. For this situation, the winding or speedometer of the tachograph of GAZ cars is used.

How it works Before

speedometer than to say how to tighten the winding or odometer readings, let's figure out on what principle the speedometer works on the Gazelle. The principle of operation of the mechanism is to measure the speed of the vehicle by mechanically connecting it to the output of the gear shaft pulley. The latter receives the driving wheels.

The axle can give a true measurement of the speed of movement, the wheels of the car will allow a more accurate measurement. This is because the toothed pulley is farther from the gearbox and the wheels are closer together, and the speed at which it rotates is set to the final speed after the gearbox. The spinning pulley speed can be the same in both first and fourth gear, but the speed difference can be enormous.

In a transmission, the output pulley contains a gear that rotates with the pulley. The gear is connected by a cable to the speedometer transmission. In the scheme, a strong cable is a cable located inside a protective rubber casing. One end of the cable is installed in a special hole and fixed on the drive gear. When the gear turns, the cable turns with it.

the end of the second cable is connected to the instrument at the control end. The shield has a magnet in the form of an axis, which is installed near the steel drum, but does not come into contact with the drum, is fixed on the needle and transmits readings to the appropriate scale. When the vehicle is stationary, the needle cable is held at zero by a small coil spring.

Instrument rewinding

So spinning like a speedometer on a Gazelle yourself? You can finish and finish reading according to various schemes, we will consider each of them separately.

Homemade ways

If you don’t know how, then you can use a simple method, which is to interfere with the operation of the odometer. Before winding the odometer, prepare a punch. If necessary, use pliers to remove the instrument panel and partially remove it by opening the glass and removing the odometer. With the help of an awl and pliers, the race is twisted into a twisted one, the automatic odometer is installed in its place at the ordered control, and the shield is connected to the on-board network.

Ready options

if you are the owner of a new model, you can use the ready-made Gazelle Business speedometer equipped with an electronic clockwork odometer. How to wind up a speedometer with such a device? There is nothing difficult in this.

Before winding it, it is necessary to find the OBD-2 connector on the car, to which you need to connect the twist:

First connect the device to the socket, the ignition must be turned off.
after activating the mode, turn on the ignition, the control lamp on the handle should light up, thanks to which you can adjust the winding speed of the readings. If the speed is slow or non-existent, use After.
sub-modes of how rewind works, you can leave the speedometer full, turn off the ignition and turn off the turn. The nuances of operating the device may differ depending on the manufacturer, so follow the Instructions when using the device.

speedometer instructions are usually among those that evaluate the quality and timing of maintenance by criteria, more precisely speaking about a car, it refers to an odometer, an integral part of an instrument that measures the distance traveled, does not violate the common name of the device, it will continue to be called so. Often for a number of reasons, sometimes subjective, it is necessary to turn the speedometer back, changing the path traveled by the car.

About speedometer types

Before you learn how you can change the readings of such a device with your own hands, you should consider its capabilities. There are several fundamentally different types of mechanics:

speedometers;
electromechanical;
electronic.

Mechanical speedometer

Gearbox The revolutions are transmitted by cable directly to the device, where the revolutions are measured and converted into revolutions. For this, a reducer with a preselected conversion factor is used. How this is done, the photo will help to understand.

In fact, it turns out that one revolution at the output of the gearbox corresponds to a certain number of meters traveled. This rotation of the output shaft is sensed by special discs (used by the instrument) with numbers indicating the measured distance.

Speedometer Electromechanical

This type of device is a further development of the device described above. In many cases, the cable was the main source of errors and was replaced. The speed sensor installed on the gearbox was connected to the device. Impulses from it came to the engine with the appropriate control, rotary gearbox. Otherwise, the operation of such a speedometer was no different from a mechanical one, resembling it in appearance and appearance.

Electronic speedometer

This type is installed on modern cars. In this case, the number of revolutions of the wheel is measured. Knowing the length of its circumference, it is not difficult to translate the number of revolutions to the distance traveled. The result is shown in Why.

Do the LCDs change the speedometer readings?

winding the speedometer is possible for various reasons, for example:

increase in fuel costs. More mileage allows you to write off more fuel. And it's not necessarily a postscript-related scam. The fact is that on an old worn-out car, fuel consumption sometimes exceeds the established norms. Thus, the higher costs must be offset.
When replacing the engine, the instrument panel. In this case, it is necessary to bring the speedometer readings in line with the new ones.
disc usage conditions other than those recommended. At the factory, the diameter may be larger or smaller than specified for the standard, respectively, the wheels will cause a permanent error in calculating the distance traveled. Here, the winding allows you to remove it, including those made by yourself.

How is the speedometer rolled up?

quite a complex and ambiguous question. All types depend on the speedometer (you can use your own methodology for each), as well as on the date of manufacture of the car. Below we consider some possible approaches to solve this problem.

Despite the fact that devices of this type remained only on old machines, it is much more difficult to work with them, purely mechanical. Here, as in other situations discussed below, it is necessary to separate the two windings:

How to wind up an electronic

Therefore, to change its readings, it may be necessary not only to supply additional speed pulse sensors, but also to reprogram some blocks. And besides, again, depending on the characteristics of the car, different for UAZ, VAZ, Gazelle, etc., as well as the year of manufacture, the method of access to the speedometer will be determined.

Therefore, it is quite difficult to do such work with your own hands, although no one says that this is impossible. But this will require the use of special electronic devices.

Due to the existing variety of machines and methods for processing speedometer data, several different options have been created that allow you to correct the readings of the distance traveled. The circuit of such a device can be made discrete both in terms of elements and microprocessor systems, but all finished products are divided into the following types:

Therefore, thanks to this, it is possible to adjust the contents of the desired cells to achieve the desired result in memory. To detect with diagnostic equipment that the memory cells have been changed, Buy.

Pulse twist to OBDII

device This is for use with non-CAN bus equipped foreign vehicles. This device is connected via a special OBDII diagnostic connector. In this case, the speedometer receives a sequence of pulses that imitate a sensor with speed signals, due to which the readings of the distance traveled change.

Speed generator

Suitable for machines equipped with work. Its ABS is based on the control of speed and wheel slip. A tornado connected to the corresponding connector imitates the operation of the wheels, and the controller, having received this information, begins to change the speedometer readings.

It is also worth noting that the model of the car and the date of its release are decisive when choosing a speedometer winding device. In some cases, the speedometer readings on a VAZ or UAZ will not be the same as on a MAZ or KAMAZ.

You can make a winder yourself or buy it ready-made, but the most important thing is to determine whether it can be used on this machine. If used incorrectly, it can simply burn electronics.

No matter how it sometimes seems, it is not the turn on the contrary that becomes strange, but the turn of the speedometer, its turn. There are a number of reasons for this, both objective and subjective. More than one device has been created to solve the problem, and you can choose a device that takes into account the release date of a particular one and allows the car to perform this procedure without a twist.
