Even more useful tips in a convenient format

For the efficient operation of the injection power unit, the VAZ-2114 car system includes a large number of different mechanisms and automated devices. You can’t say that the “fourteenth” car is filled to capacity with electronics, but if you look under the hood, you can find all kinds of VAZ-2114 8-valve injector sensors.

The main purpose of electronics is to monitor the condition of vehicle components and assemblies. The received data is transmitted to the main “brain” center of the car. Thanks to this approach, the driver no longer needs to spend a long and exhausting time looking for reasons for deviations from the operation of a particular system. The ECU will provide all the information. What sensors are involved in the operation of the VAZ-2114 and where are they located?

General information about VAZ-2114 sensors

Sensors look like small mechanisms. However, their role in the operation of the entire vehicle system is simply colossal. They signal the remaining fuel in the gas tank, inform the driver of the coolant temperature, and determine the position of various engine elements in a certain operating mode. In order to know your car well and understand what could fail in a given situation, you need to know the entire list of mechanisms involved in the system.

We list all the sensors on the VAZ-2114 injector 8 valves, which are the most important:

Crankshaft positions.
TPDZ.
Camshaft position sensor.
DTOZH.
Speed.
Idle move.
DMRV.
Lambda probe.

These devices are in most cases located in the engine compartment. Almost all of them are installed at the factory during vehicle assembly. But the driver himself can install some sensors at any suitable time. It is also important to know how each of these devices works and what primary task it performs.

VAZ 2110 engine compartment description

Dear visitors of the “Cars” website! We will be very grateful for your comments on the video clip “VAZ 2110 engine compartment description”; registration is not required for this. We also ask you to let us know if you have any problems playing the video.

Great

But why is it not possible to pull out the whole bunch? My car stalled and wouldn’t start, 21114 124, the state first showed 0328, then it disappeared and started showing 1602, 0338, 0340. I wanted to pull the whole bunch, but there it was. What should I do? I'm guilty of damage at the bottom, where the beam enters the torpedo, I can't reach it with my hands

Don't interfere with the machine's work

very informative. Keep stopping them from working. This is the most interesting thing. Stop something from working

how can I contact you I need your advice if possible call me from me subscribe 79780067322 my name is Evgeniy

Crankshaft position sensor

You can often hear drivers with many years of experience calling this mechanism nothing other than a synchronization sensor. This name comes from the principle of operation of the device. The tasks of the DPKV are to synchronize the operation of the electronic unit and the gas distribution mechanism.

The VAZ-2114 is equipped with an inductive type DPKV. The cost of such a sensor is relatively small. If a vital controller for a car fails, most drivers prefer to immediately replace the device with a new one.

If the DPKV breaks down, further operation of the vehicle will become impossible. Without this mechanism, the fuel supply system will stop working, because the ECU will not receive information about when it is necessary to give a command to inject fuel into the cylinders. The location of the DPKV is in close proximity to the camshaft.

Electronics are responsible for fuel delivery in the VAZ-2114 car system. Without TPS, the control unit will not be able to determine the optimal time to supply gasoline. Deviations from the correct operation of the TPS lead to an increase in the amount of fuel consumed. The operation of many other car systems depends on the angle at which the remote control is located: cooling, fuel supply.

Schematic electrical diagram.

Features of replacing the driveshaft crosspiece of a VAZ-2107: 3 important tips for choosing a part

The schematic diagram retains the sequence and structure of the block diagram, but instead of general functional blocks, the full composition of the elements of the device (device) is shown, depicted in the form of conventional graphic symbols

. Each part is depicted with the number of pins that real parts have, and the connections between the pins are shown in such a way that you can trace all the circuits and connections in detail, and easily understand the processes taking place and the principle of operation of the device.

For ease of reading, next to the symbolic image of the part its alphanumeric designation

, which defines information about the part: functional purpose, location and marking in the diagram. Alphanumeric designations are indicated in abbreviated form and consist of a certain number of letters of the Latin alphabet and Arabic numerals, written sequentially, on one line and without spaces.

Letter designation

taken from the name of the part and indicated by one or two first letters, for example,
R
- resistor,
C
- capacitor,
VD
- diode,
VT
- transistor,
SA
- switch,
XP
- two-pole plug,
EL
- lighting lamp, etc.

Digital designation

indicates the serial number of parts of the same type in the circuit, for example,
R1
,
R2
,
R3
, etc., or
VD10
,
VD11
, etc.

Let's draw a schematic electrical diagram of a table lamp, and for ease of reading the diagram, at the first stage, we will highlight its main elements with green rectangles.

Looking at the diagram, we can say that to power the table lamp, an alternating voltage of 220 V is used, which is supplied through the XP1

and switch
SA1
is supplied to light bulb
EL1
.
That all elements are designed for an operating alternating voltage of 220 V, and that the operation of the lamp is carried out by the position of the contact of the switch SA1
: when the contact is closed, the lamp
EL1
lights up, when it opens, it goes out.

From the diagram it can be seen that the upper terminal of the XP1

connected to the left terminal of the switch
SA1
, the right terminal of the switch contact is connected to the upper terminal of the light bulb
EL1
, and the lower terminal of the light bulb is connected to the lower terminal of
the XP1
.
Switch contact SA1
is shown in an open state, which corresponds to its initial position and the off state of the table lamp. The electrical connection between the terminals of the elements is depicted by segments of horizontal and vertical lines.

And at the same time, the circuit diagram does not give us a complete picture of the table lamp, since it does not indicate information about the design of the lamp and the dimensions of the parts. The fact is that when studying the principle of operation, there is no need to know how, for example, the light bulb is made (size and shape of the bulb, type and size of the base, coil resistance, etc.), what design the switch or plug has

If all this information were indicated on the diagram, they would only distract attention to unnecessary details that are not of fundamental importance

But still, to expand the functionality, some part of the design data of the elements (power, type, method of connection) is indicated on the circuit diagrams, because in some cases it turns out to be the main and only document that is used to guide the manufacture, adjustment, maintenance and repair of equipment.

If we compare the structural and circuit diagrams, then what they have in common is the order of arrangement of the elements and the path of the signal (in our case, electric current), which goes from left to right, i.e. in the direction familiar to ordinary reading. However, on circuit boards, chassis or panels of real devices, elements may be arranged differently, subject to rules aimed at minimizing parasitic connections between individual elements, nodes, and blocks. Therefore, the arrangement of elements inside a real device may not correspond to the circuit diagram.

The considered structural and circuit diagrams are intended mainly for studying the principle of operation, and depending on the type, they provide a visual representation of the functional or elemental structure. To have an idea of the design of the table lamp, the approximate arrangement of the elements and methods of connection between them, use the connection diagram

or
wiring diagram

Camshaft position sensor

This mechanism is located near the cylinder block. The main task is to transmit data to the ECU regarding the current operating cycle. Among specialists, the mechanism is called a Hall sensor. The operation of the device is based on the following principle: in accordance with the location of the crankshaft, the position of the gas distribution mechanism is determined. The data received by the sensor is reported to the electronic unit. Fuel is injected and the mixture is subsequently ignited.

Steering

To move normally in a car, the driver needs to make turns, U-turns or detours, that is, deviate from straight-line movement, or simply control his car so that it does not drift to the side. For this purpose, its design provides steering control. This is one of the simplest mechanisms in a car. Let's look at the names of some of the elements below. The steering system consists of:

These devices consist of a steering system that is connected to the front wheels by steering and brakes.

Modern cars use an additional element - power steering, which allows the driver to use less force to turn the steering wheel. It comes in the following types:

Knock sensor, DTOZH, speed and others

In addition to the above mechanisms, other very important devices can be found in various corners of the engine compartment. The location of the VAZ-2114 injector sensors is quite chaotic, some are located directly on the power unit, others in other places - the gearbox, on electrical circuits.

Some equally important mechanisms include:

The knock sensor is sensitive to various engine vibrations. Based on the received pulses, the ECU determines the qualitative composition of the mixture. Located on the cylinder block.

Engine temperature sensor - the only and simple, but extremely important task assigned to this device is to monitor the coolant temperature.

Speed sensor – from the name itself it is clear that this controller is necessary to measure the speed of a car. The DS transmits impulses to the ECU, which processes them and determines the speed of the car; the resulting result is displayed on the instrument panel by the speedometer.

Idling speed – not only reads information, but also corrects engine operation. DXH, using a special needle, controls the pipe - closes and opens. Due to this, the amount of oxygen supplied to the throttle assembly changes.

Mass air flow sensor - reads the data and transmits it to the control unit, which, based on the information received, determines the optimal ratio of the various components of the fuel-air mixture. A breakdown of the air flow sensor leads to the fact that the car significantly loses power, and the driver begins to feel a significant increase in the amount of gasoline consumed by the car.

Sanding chips before painting

If you decide not to remove all the old paint, but only to update the hood, you need to very carefully remove and treat the places where the stones are chipped.
There are always a lot of them on the hood, because this is one of the most vulnerable places of the car. The chipping area must be covered with masking tape. And only after this the treatment is carried out: washed, dried and treated with a degreasing liquid. After this, we clean the edges of the chips with coarse sandpaper and remove the rust. Then you should clean the chipped area with a brush, rinse thoroughly and treat again with a degreaser.

If the scratch is deep, then it must be puttied. You can use regular aluminum putty. After drying, the treated area is sanded. Application of primer is not necessary when using this putty.

Before painting, we matte the entire remaining part of the hood (rubbing off the glossy layer). And after that we move on to the standard painting procedure, which is described below.

What is under the hood of the VAZ 2113

I think it is important that the car looks beautiful not only from the outside, but also from the inside. I mean what's under the hood

I’m not talking about technical characteristics, everyone has their own power and their own parameters, some drove a herd of horses there, and some a small pony, but this pony needs to look great. What is under the hood of the VAZ 2113?

There are parts that need care and attention. I'm planning to install a new receiver soon, it will be slightly larger

Since the car is still in the garage and is ready for all sorts of experimental actions, I cut out a place in the frame there. Then it turned out that I had to abandon what I had started a little, unforeseen worries, you know.

After some time, I returned to the garage and continued what I had started, purchased a primer and applied a thin layer under the hood, let it dry, then painted it yellow. Why yellow, you ask, but I like this color, so sunny and vital, as if nothing under the hood will break. After painting I had to wait a couple more days for everything to dry thoroughly. It is worth noting that you need to select heat-resistant paint, because under the hood there is exposure to high temperatures, sometimes associated with the release of any liquids, such as oil or gasoline, so you need to select durable, special paint. I won’t advertise my paint, but I will say that during the entire run-in period it didn’t even change color, let alone slip. They frightened me with the fact that I would never pass a technical inspection in my life, it’s not true, I passed everything without any particular difficulties, I didn’t give anything to anyone, everything was fair and according to the law.

Metallic scraping noise when braking

Bandit cars of the 90s: list. popular cars of the 90s

We have already written about this above, but we should consider squeaking brakes in a little more detail. Brakes sometimes create a characteristic squeaking sound, especially if the pads are wet. Some types of brake pads (especially semi-metallic pads) can squeal or squeal even when they cool down during the winter season. If you hear metallic scraping noises when braking, like someone running a file over rough metal, your brake pads are worn out and your car needs brake service. You shouldn’t hesitate to do this and here’s why.

Worn brake pad

At low speeds, worn brakes work just as effectively, the only difference is an annoying sound. However, at medium and high speeds (50 km/h and above), such brakes may not work at all. In fact, if brakes that are badly worn are "switched on" at speed, there is a risk that the friction material left on the pads will separate from the backing plate. This will cause the brakes to fail and, pressing the pedal, the car will continue to move.

Wiring diagram VAZ-2114 new models

The updated engine has a new injection scheme, so it was necessary to use some new devices, as well as replace the ignition coil with a more efficient one and adapted to Euro 3 conditions. In order to comply with them, the engine had to minimize the amount of CO at start-up. And for this it was necessary to lean the mixture. Since a lean mixture ignites worse, it needed a more powerful spark to spark. This explains the use of a coil of increased power.

Do it yourself lighting of the engine compartment on VAZ 2112, 2111, 2110

Many people are faced with the problem that domestic cars do not have engine compartment lighting. This phenomenon greatly disturbs the driver when the engine needs to be repaired at night and the parts are not visible at all. Naturally, a thought immediately arises. Often, many motorists had breakdowns at night and there was no lighting at all. In this case, you had to use flashlights or lighters, which were held in one hand, and the other hand needed to repair the part, which is not a very convenient way to repair.

Everything was done, but time and effort wasted. After such unforeseen situations on the roads at night, it is best to install backlighting on the VAZ 2112, 2111, 2110. So, the work begins.

This article will talk about installing backlighting with LED bulbs or regular halogen ones. To successfully complete the job, you need to have the following tools and materials.

1. Engine compartment lamp from VAZ 2113 -2115 cars 1 pc. 2.Two-core wire, with a cross-section of 1 mm, approximately five meters long. 3.On and off button 1pc. 4. Hanging fuse 1 pc. 5. Flat fuse for five amperes 1 pc.

The installation begins. To install the light bulb, you first need to remove the hood trim, if there is one. Then you need to choose the place where the backlight will be attached. It is best to install on the left side, because that is where all the very important elements of the motor are located. You need to make a mark in this place. You need to make a hole in the hood trim. You need to do this in order to install a light bulb there.

We make a hole and install the entire structure back to see how everything will look, after which we remove everything back. Then, using a thin drill, you need to make a small hole in the hood stiffener rib, into which the lamp fastening element will then be screwed. Then you need to lay the wires. The wire must be pulled under the factory casing. The wiring must be routed to the switch. You need to run the wiring in the plastic part of the hood, after making a hole there. Then we solder all the wires and install them on sealant for installation in a longitudinal hole.

Now we install the light bulb and secure it with wires. One wire must be connected to the positive of the battery; the wire must first be connected to a 5-amp fuse, which will thus increase the life of the light bulb. In this case, the second wire can be easily connected to the hood terminals. In this case, the limit switch will automatically turn off the backlight, even if the button on the dashboard is turned on. Instead of simple and traditional incandescent lamps, it is best to install LEDs or LED strips. In this case, you need to do the work exactly as described above, but the result will be much better. This is how the backlight will look if you install an LED strip.

How to insulate yourself

Motorists insulate the car hood with their own hands.

Independent arrangement includes the following stages of work:

Preparation. First, you will need to dismantle the standard hood sound insulation (if available). The operation should be carried out carefully, trying not to damage it. Afterwards, the working surface is thoroughly washed and degreased. Creating templates. You need to make a pattern for the insulation. For these purposes, use old wallpaper or newspapers. It is necessary to carefully cut out the templates, according to which the insulation elements for the hood will subsequently be cut out. The remaining thermal insulation is cut into small strips, which will subsequently be attached to the stiffeners of the body element. Installation of insulation. When performing this operation, you need to stock up on a small roller, glue and insulation. If work is carried out in an insufficiently heated room, use a hair dryer. The adhesive is evenly applied to the degreased working surface, then the insulation is carefully applied from the corner and gradually fixed to the hood (if you stick the element right away, folds and air bubbles may appear). Afterwards, carefully roll over the glued insulation.

Care must be taken as bulges and dents may appear on the outside of the hood due to excessive pressure on the inside of the body element.

When the cold weather ends, the thermal insulation is dismantled. Before new use, the insulation is repaired and reinstalled on the car.

To quickly warm up the car in low temperatures, you need to use thermal insulation of the vehicle's engine compartment. First of all, the warm-up time is reduced, and as a result, fuel consumption is reduced

The engine cools down more slowly, which is important for motorists who use their cars intensively with short stops. For maximum efficiency, not only the hood, but also the air ducts along with the radiator grille are insulated
