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.

Device

An injector engine consists of several main elements. As in any car, fuel comes from the tank through the fuel line. Along the way, the combustible mixture goes through several stages of purification: a fine filter and a coarse filter. There is no strainer, such as was located on the carburetor inlet.

In general, on a VAZ car with an injector engine, instead of carburetor throttle valves, a throttle assembly is used. Its circuit is directly connected to the adsorber of the electromagnetic valves. It is he who regulates the fuel supply to the injectors.

As far as everyone knows, the correct operation of the engine directly depended on the amount of combustible mixture. It was controlled by the volume of the primary and secondary carburetor chambers, and the jets. In the version with an injector, a combination of three valves is used: two-way, safety and gravity. It is they who control that there is no overflow of the spark plug, or, conversely, a lack of fuel in the combustion chamber.

Fuel pressure control

In order for the engine to produce normal power and have synchronous operation of the valves, a fuel pressure regulator is installed in front of the injectors. With increased or decreased pressure, the regulator is activated, ensuring further operation of the piston.

Well, the last element of the device is the nozzles. They regulate injection into the combustion chamber. Since fuel is supplied to the injectors under constant pressure, they almost never clog. That is why the service life of a VAZ 2114 engine with an injector, without outside intervention, is much longer than with a carburetor.

In the period from 1999 to 2011, VAZ 2114 models with an injector engine were produced in two versions, which differed in engine capacity: 1500 and 1600 cm/cc. Their design was slightly different, not the circuit itself, but some components not related to the fuel system.

For example, the ignition system on a one and a half thousand engine has an ignition module, while on a 1600 cc engine a coil was installed.

Also, in addition to the above positive qualities of the injector, I would also like to note the reduced fuel consumption. For example, if a carburetor type engine consumed 10 liters per hundred, then the injector will take 8.5 - 9 liters. Therefore, if you have such an opportunity, then it is better to choose this type of engine. It may be more expensive, but remember: you are paying for personal comfort.

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.

Another video with an example of replacement

The VAZ-2114 car uses a hidden engine cooling circuit with an injector. It is highly complex and includes 28 elements. Traditionally, the assembly of the cooling system of this car is not of high quality. Therefore, throughout the entire period of operation, it requires constant monitoring, regular maintenance and repair. In this regard, many owners of this car are interested in the nuances associated with independent maintenance, repair and operation of the cooling system, among which the most common questions are:

1. How to properly replace the coolant mixture?
2. How to flush the cooling system?
3. How to remove air from the VAZ-2114 cooling system?
4. How to properly replace the cooling system pipes?

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.

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.

Fuel system

It consists of many components: a fuel pump, a fuel pressure regulator, a fuel filter, a fuel line, injectors and a ramp, thanks to which fuel enters the engine. The ramp is a strip on which the injectors and fuel pressure regulator are located, and is attached with two bolts to the intake pipe. The injectors are mounted on the fuel rail, its function is to supply fuel to the engine. An injector is an electromagnetic valve that opens and sprays fuel under pressure in a thin stream after it receives a corresponding impulse from the ECU. Upon contact with the heaters, the fuel evaporates and is fed through the needle pin into the combustion chamber.

What's under the hood? (for Dummies")

So, it all started with my purchase of a car (the choice fell on the VAZ 2107). And as you know, purchasing a car obliges the owner (to begin with) to understand at least a little about its maintenance and, accordingly, repairs. But for me (a novice car enthusiast) everything that was under the hood was a huge secret. Of course, experience is gained over the years, and since I didn’t have the latter (and I knew very little, practically nothing about the “insides” of the car), little by little I began to understand the design features of my Zhiguli. Therefore, so that to my colleagues (novice car enthusiasts) the engine compartment and everything in it does not seem too “dark”, in this article I will tell you what is where and what is responsible for what.

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.

Before you go

Those who nevertheless studied at a driving school and remember the teachings of the teachers know what to do before driving a car. This is especially true for our domestic models, which do not have an abundance of sensors and a computer that monitors all indicators.

Check the levels of working fluids, oil, coolant in the radiator, even in the washer - these minor checks will give you the opportunity to never find out how a car radiator is repaired, and you will not be repairing the car yourself, much less find out how much a major repair costs jammed engine.

Engine compartment of VAZ 2114

Also, look under the car more often, since most breakdowns begin with minor leaks, which an attentive owner will definitely notice in time.

Driving technique

Gear shifting and clutch operation are those nuances that are definitely worth paying attention to, since the ability to change gears in time and smoothly release the clutch greatly affects ride comfort.

VAZ 2114 clutch design

In order to notice in time that a car is behaving somehow wrong, it is not necessary to thoroughly know its design, but every driver simply must know how a car’s clutch works. VAZ cars mostly have a permanently closed clutch, which means that when you press the pedal, you release the pressure and driven discs from the frictional engagement.

Clutch pedal operation

Among the nuances of operation, it is worth noting that if the clutch is not fully released, trying to pull the car up a steep climb, it is easy to burn the friction linings on the driven disk. This will entail forced repair of the clutch unit. So if you want your clutch to work happily for a long time, try to keep it less fully depressed or released, of course, without sacrificing ride comfort.
