In 1995, the Volzhsky Automobile Plant began production of a car, at that time a new generation VAZ-2110 with a sedan body.
Immediately, two more cars were produced on the basis of this model, with a station wagon body - VAZ 2111 and a hatchback - 2112.
Production of all three models continued until 2007.
The 10-series models belonged to the budget category of cars, which naturally affected the quality of materials and the car’s assembly itself, but in general, despite the questionable build quality, the car turned out to be in demand.
Historically, VAZ cars have never been famous for their reliability; this trend has not bypassed the 10th family either.
But it is worth noting that the maintainability of these machines is quite high; many problems are completely fixable, even in garage conditions. And the cost of spare parts is significantly lower than for foreign analogues.
Like any car, the VAZ-2110 and models based on it have weak points that you should first pay attention to during operation.
Next, we will go through all the components of the VAZ-2110, 2111, 2112 cars, with which problems most often arise, and at the end we will dwell on the reviews.
Model history
The tenth family of front-wheel drive models from the Volzhsky plant began in 1995, with the 2110 sedan model. Then in 1998, the plant launched the assembly of the station wagon - 2111. In 1999, the plant began producing hatchbacks.
In the first years of production, the 2110 used a 1.5-liter sixteen-valve engine. At that time, this was the maximum capacity of the plant.
In 2000, the plant introduced a new version of the hatchback - VAZ-2112, 16 valves. Compared to the conventional eight-valve version, the car had more power and dynamism. The model immediately captivated car enthusiasts; its appearance was sporty.
Options
The car was produced and is offered in “Lux” and “Norma” trim levels. The “Norma” differs from the luxury version only in that it did not have a trip computer, fog lights, a set of alloy wheels, or a headlight cleaning system.
“Norma” is equipped with electric windows for all four windows, central locking, remote trunk opening drive, height-adjustable steering column, and immobilizer.
What’s most interesting is that none of the trim levels (no matter how expensive they are) have air conditioning. By today's standards, this is quite a big disadvantage, because of which drivers are increasingly looking towards used foreign cars.
Crankshaft position sensor (CPS)
Often the engine stalls due to problems with the DPKV. To check, you will have to remove this sensor from the engine. Be sure to mark its position on the engine.
After removal, you need to measure the resistance of the sensor inductive coil. The multimeter should show a resistance between 550 and 750 ohms. Anything more or less indicates a sensor malfunction. It needs to be replaced. There are other checking methods, but they are difficult to apply in a regular garage.
Now a short video with another reason.
Appearance and body structure
As for the dimensions, the VAZ-2112 (16 valves) decreased in length by 93 mm. This change occurred in the rear overhang area. But at the same time, the size of the wheelbase did not transform. The body length was 4170 mm. And the height of 1676 mm and width of 1430 mm remained traditional for the “tenth” family. The top line on this body very smoothly turns into a fairly short rear overhang and a large wing. This design allowed the developers to make the car more manageable.
If you compare this hatchback with more classic VAZ models, it has better aerodynamic characteristics and a modern appearance. The model is very popular among tuning enthusiasts.
The fully galvanized body of the “tens”, which became very popular in its time, is still subject to corrosion. Many owners of new cars did not consider it necessary to carry out anti-corrosion treatment. The bottom very quickly rusted to holes.
Interior and salon
The interior of the VAZ-2112 (16 valves) features all the best from two brothers. The best characteristics of the station wagon's interior are combined here. The backs of the rear seats are divided into two parts. Each of them can be folded. This significantly increases the trunk volume. And this is the only advantage. Inside, everything is more modest than in any foreign cars of the same classes and the same years.
Owners say there is little light both in the cabin and on the dashboard. All the panels seem to be perfectly assembled, but something still creaks somewhere. The central tunnel next to the handbrake is equipped with buttons to control the window lift - it is believed that this is not very convenient to use. There are no such options for rear passengers - even mechanical handles are not provided in the basic configuration.
Another disadvantage, according to the owners of the VAZ-2112 (16 valves), is the complete absence of at least some sound insulation. When driving with music on, you can clearly hear the engine and power steering working.
The big problem is the incredibly cramped pedal block.
From the edge of the brake to the console is just over 10 cm. Many people complain about this very narrow opening. In order to operate the gas pedal, you have to turn your foot sideways. And if you don’t turn it out, then when you press the accelerator pedal, your foot catches the brake. In 2110 this is all right. Maybe the reason here is that the scarf overlay is made more convex? Maybe.
And the front seats are made well. They are additionally equipped with side support. But even here everything is not so clear. Many people complain about inconvenient adjustments. But large people fit perfectly into the cabin and into the driver's seat - this is an advantage, since there is not much space.
Another positive feature is the low height of the trunk shelf. Once the fifth door is opened, nothing interferes with loading.
The car has good visibility. But the mirror in the cabin is not very convenient to use due to the large pillars and the tilt of the glass. Rear passengers also note excellent performance in this regard. But there's little headroom in the back.
Owner reviews
But if we take it as a whole, this family of VAZs performed well. Of course, many characterize the VAZ-2110, 2111, 2112 cars only on the negative side, but there are also enough car owners who like these cars.
What's positive.
One of these owners points to the good torquey engine, which makes it feel good when overtaking and maneuvering.
The second car owner points out that with the right approach, cars of this family are very reliable, you just need to take care of them.
The third likes that the fuel consumption of the VAZ-2110 is not that high, and this car is not particularly sensitive to fuel quality.
And the fourth car owner likes the fact that the cost of maintaining a car is low, and spare parts are very easy to get.
Negative reviews.
Opponents of this car also have enough arguments.
The first one does not like the poor corrosion resistance of the body, especially near the windshield seal.
The second owner notes that although the spare parts are cheap, the car breaks down much more often than foreign models in this price range. And there is a high probability of purchasing non-original parts that last much less.
Read on the topic: How to buy spare parts correctly.
The third indicates eternal problems with interior heating, and what causes the most inconvenience in this matter is not the occurrence of the malfunction itself, but the difficulty of eliminating it.
And the fourth notes the overall poor reliability of the car, so the VAZ-2110 constantly requires investment.
Chassis and steering
The main complaint about the chassis is excessive softness. This is all due to the redesigned suspension system. But many drivers lack feedback. And at the same time the car handles perfectly. By turning the steering wheel a little, you will immediately feel the result. In terms of inertia, this hatchback is many times superior to both a sedan and a station wagon. But turning the steering wheel at low speeds is quite difficult. The fault for this lies entirely with the hydraulic booster. It reduces the effort, but this does not make the car more obedient.
The driving characteristics are quite confident. The car is controlled on ice. Of course, there is no ABS here. The brakes are vacuum-assisted and have discs at the front and drums at the rear. They brake – and it’s good.
Engine VAZ-2112 (16 valves)
The engineers used something new as a power unit. The unit was not created anew, but on the basis of the 21083 engine. It retained all the geometric characteristics of the 83rd, but at the same time it was completely different from it both in power and in other characteristics. Famous car brands took part in its development. The engine is highly efficient. Among the disadvantages is weak torque at low speeds. Owners also write in reviews about a weak belt drive if the timing belt breaks.
VAZ-2112 (16 valves) has an engine capacity of 1.5 liters. The power it can produce is 93 hp. With. The torque is 133 Nm at 3300 rpm. As for environmental standards, the engine is designed for Euro-3. There are 2 valves per cylinder. One is for inlet, the second is for outlet.
The injector is
Before we look at the signs of a faulty VAZ 2110 injector , let's understand what it is. In simple words, the type of injection into the cylinders. A couple of decades ago, it replaced the carburetor. Since the principle ensures maximum combustion. Due to careful dosing of gasoline and air. And also mixing with each other. Therefore, it is difficult to achieve this by spraying the carburetor.
So, let's understand this structure. Firstly, the electronic control unit (ECU) is located in the cabin, at the feet between the driver and passenger. The ECU is the heart of the unit. Since it controls the entire structure. That is, it regulates the supply of the combustible mixture. And also informing about problems with the “ check engine ” indicator.
Next is the fuel pump, which is located in the gas tank. From it, gasoline flows through the main line through the filter into the ramp. What is located directly on the motor. As a result, there are injectors on the ramp. Which spray gasoline, mixing it with air into the cylinders.
Cylinder block, connecting rods, pistons
The VAZ-2112 engine (16 valves) is equipped with a block cast from high-strength cast iron. At first glance, it seems that it is completely similar to model 21083. But this is not so. The main difference is the 10 mm smaller diameter of the head bolts. Other bosses for injection system sensors and another honing technology.
The connecting rods are made of steel by forging. They are distinguished by their I-section. These same connecting rods can be found on the 2110.
The pistons are steel, hollow, floating. The finger has a diameter of 22 mm. Length – 60.5 mm.
VAZ-21124
Also, the 21124 unit was installed on the “two-wheeler”. Here the volume is 1.6 liters, the power is 89 liters. s., torque – 131 Nm. The power system is also distributed injection. The engine supports Euro-3 and Euro-4.
This engine is a continuation of the 2112 line. It was possible to increase the volume using a crankshaft with a larger crank radius with the same cylinder diameter. The cylinder block here also has an increased height.
Here they were able to solve the problem of valve bending, and the characteristics are at a sports level.
Nutrition
Often, the cause of engine tripping is the power supply system. First of all, the problem may be caused by low-quality fuel. To check, try changing the fuel. You can also try cleaning the injectors.
Their blockage can also cause tripping. For this purpose, special compounds are used. It is not recommended to pour cleaners into the tank. It is better to make a temporary power supply system; cleaning is carried out according to the instructions indicated on the package. After cleaning the injectors this way, the spark plugs should be replaced with new ones.
Ignition system
An electronic module is used as the heart of the system. Car owners write a lot about how problematic it is. You should select candles for it very carefully.
The VAZ-2112 ignition (16 valves) has two coils. One is used to operate the first and fourth cylinders, the second – for the second and third. If there are problems in the module, the spark disappears in pairs. The system itself is not maintained or repaired. Its control is entirely given to the controller.
There are several sensors in the system. This is a crankshaft position sensor that sends a signal to the ECU, and then the “electronic intelligence” calculates how to operate the coils. In the formation of the mixture and ignition, the familiar mass air flow sensor, coolant sensor, and knock sensor, which are familiar to many, work. Other VAZ-2112 sensors (16 valves) work the same way. For example, throttle, oxygen, exhaust gas sensors.
Elimination methods
Before moving directly to methods for eliminating the problem, it is worth noting that you do not need to get into the components of power units if you do not know the design. It is best, in such cases, to contact a car service, where everything will be done quickly and efficiently.
Poor quality fuel
Statistics of low-quality fuel and how it gets to gas stations The issue of low-quality fuel that gets into the fuel system of a car has been raised more than once, which can lead to various types of breakdowns. So, poor acceleration can be directly related to the fact that fuel has entered the system and does not detonate well. You can fix the problem by draining the gasoline and cleaning the fuel tank.
Fuel system
If the fuel system is clogged, namely poor operation of the gasoline pump or clogged injectors, this effect may occur.
To eliminate the malfunction, it is necessary to dismantle the elements and clean them thoroughly. If cleaning does not help, you need to identify damage and replace parts. For the fuel pump - replacing the mesh and directly replacing the fuel filter itself, which is no longer able to clean gasoline, but for the injectors - cleaning on a special stand.
Ignition
The reason for poor acceleration may lie in faulty ignition elements. Thus, breakdown of high-voltage wires or failure of spark plugs can become the main problem. To eliminate the effect, it is necessary to check the resistance of the element, as well as visually inspect for insulation damage or cracks. If defects are found, the wires and spark plugs must be replaced. The choice of spark plugs must be approached very carefully.
ECU errors
Troubleshooting ECU errors using a laptop The electronic control unit is designed to prevent and signal faults, although sometimes it itself can cause the problem. Thus, the accumulation of errors can lead to incorrect interpretation of incoming signals, both incoming and outgoing. Therefore, it is worth connecting to the ECU and looking at the errors that pop up. If necessary, they must be canceled.
Clutch
Worn clutch disc. To resolve the problem, you need to replace the disk. The process is labor-intensive and long, so you will have to stock up on patience and tools.
Engine problems
Engines of the VAZ-2112 family are very reliable.
Major repairs are what the owner faces if the engine loses compression. Loss of compression can occur for many reasons, the most common of which is simple wear and tear. A compression test will show the compression ratio and indirectly indicate whether there are reasons in the engine itself.
Typical engine faults
Many car enthusiasts who own an “iron horse” with a 2112 engine complained about valve deformation when the timing belt breaks. This is a typical malfunction. The repair is simple. You just need to change the pistons to those on 21124. The problem is solved there, but the price for this will be a decrease in power. If you do not want to lose in this indicator, you need to constantly monitor the belt. Listen to the sounds. First the rollers squeak, then rustle.
In addition, the engine can triple. How to deal with this unpleasant phenomenon? Check the compression level, ignition module, wires. If the speed fluctuates, then you can suspect the throttle valve, idle air control, crankshaft position sensors, mass air flow sensor.
Another malfunction is noted. It can occur at idle and while driving. The engine sometimes stalls when changing gears. Clean the throttle body or throttle sensor.
If the unit does not start at all, check the starter and battery.
The ignition or power system may also be malfunctioning.
With proper care of this engine, the VAZ-2112 (16 valves) will not need repairs. Just follow the manufacturer's instructions and perform regular maintenance. All instructions about basic operations will not cause difficulties.
Causes
There may be several reasons for the lack of proper speed gain:
- There are problems with the air supply;
- The ignition has failed;
- Fuel system malfunctions have occurred;
- There were problems with the exhaust system.
Fuel system problems are common in gasoline engines. They are the most common. Therefore, you should start with checking it.
Fuel system
If problems arise when accelerating the car, start checking by inspecting the fuel system.
- Most often, the engine stops gaining momentum because the fuel pump fails. At first, this may have a slight effect, sometimes unnoticed. Over time, as the pump wears out, the speed and power will begin to drop, and the acceleration dynamics will decrease.
- If the fuel pump is partially damaged, it still partially performs its functions, but is no longer capable of delivering the same volumes of fuel. This results in fuel starvation and power loss.
- The best solution to a problem with the pump is to replace it. It is better to trust repairs to specialists.
Ignition
If the ignition fails, you will have to conduct a comprehensive check of all system components that may cause a drop in engine power and speed.

Peculiarities
Prices
At the very beginning, they asked for more for this hatchback than for other models. It was considered quite expensive. Perhaps the reason for this is the power windows and lock. However, a little later, prices dropped, and configurations and equipment became richer.
Today, the average price for a VAZ-2112 car (16 valves) is from 90 to 250 thousand rubles, depending on the configuration, tuning, and engine. The car is suitable for various changes, so owners modify it.
According to user reviews, the most optimal cost is about 150 thousand rubles. Since at this level it is not rubbish that is offered.
So, we found out what technical characteristics, price, reviews and configurations the VAZ-2112 car has. Happy shopping!
