VAZ-2109 diagram

The VAZ-2109 car was produced at AvtoVAZ from 1987 to 1997. Years of production 21099: 1990-2004 - in Russia, 2004-2011 - in Ukraine. Here are colored wiring diagrams (for the injector and carburetor) with a description of all the elements for various modifications. The information is intended for self-repair of cars. Electrical circuits are divided into several blocks for ease of viewing via a computer or smartphone; there are also circuits in the form of a single picture with a description of the elements - for printing on a printer.

Engine Features

VAZ 21083 (carburetor) has several characteristic features that are important for the owner of a V8 to know. Description of some engine features:

1. It is worth refusing to use low-octane fuel for this model. This negatively affects the operation of the carburetor. Initially, the engine was created for 93 gasoline.
2. The wad is located on top, which allows you to get rid of inertial moments.
3. The engine has a belt drive - the car owner should change the guide rollers and the belt itself every 50 thousand km.
4. In this series of units, the piston diameter was increased to 82 mm.
5. The reliability of the motor is explained by its design. If the drive belt breaks, the moving pistons do not collide with the valves. This also makes it easier to overhaul the engine.

In addition, the unit is lightweight and economical. Such features appealed to many domestic car enthusiasts. The injector provides more economical fuel consumption, as well as ease of starting the engine in any weather conditions.

Malfunctions

Problems and malfunctions during operation of the solenoid valve. This part is part of the carburetor and affects the ignition process, which is why its breakdown leads to the following troubles

Engine problems

Problems in the operation of the VAZ 2109 carburetor engine

Causes How to fix the problem The carburetor does not work due to severe contamination of the channels or jet. The mentioned parts of the carburetor are cleaned using compressed air. It is important to control the air supply to prevent damage. Liquid has entered the carburetor or jet. Also, use compressed air to clean carburetor systems from residual liquid. Check the fuel tank for sediment and drain if necessary. The starting device does not work due to depressurization of the system. The trigger diaphragm is broken. This may reduce the productivity of the VAZ 2109 engine. Check for damage to the diaphragm, replace it if a malfunction is detected. Problems with the ignition system. Complete or partial inoperability. Carrying out diagnostics of the ignition system, replacing faulty parts with new ones. Air entering the brake booster compartment. This usually happens due to a torn vacuum hose. Such a breakdown affects the performance of the econometer, ignition distributor and vacuum regulator-sensor. Check the hose, find damage and repair it. You can also completely replace the hose

It is necessary to pay attention to the mounting clamps; if necessary, they should be tightened. Damage to the gasket in the intake manifold connections. Such a breakdown leads to air leaks into the intake manifold.

Affects the performance of the carburetor and engine of the VAZ 2109. Check for damage to the intake pipe. Tighten all nuts. If this does not help, then most likely you will need to replace the gaskets with new ones.

Equipment diagram for VAZ-2109 injector

The VAZ 2109 wiring for the injector has many connectors for connecting sensors to the computer.

1. TPS (throttle position sensor);
2. DPKV (crankshaft position sensor);
3. DT (temperature sensor);
4. DSA (vehicle speed sensor);
5. Canister purge valve;
6. MAF (mass air flow sensor);
7. DD (knock sensor) and others.

The weak point of the harnesses is the power wiring on the bottom shelf of the radiator, which is constantly exposed to high temperatures and in this place it is in no way protected from water and dirt. Another problem is a harness under the carpet next to the driver's seat. Moisture constantly accumulates there, and in order to remove it, you need to dry the floor, inevitably tugging on the rope.

Since the mid-90s, VAZ 2109 began to use engines with an injection system, which greatly changed the electrical layout of the engine compartment and instrument panel. Below is an electrical diagram of a 1999 car with an ECM type GM ISFI-2S and January 4/4.1.

Relay and fuse box diagram 2109

The fuse blocks do not depend on the fuel injection system used - carburetor or injector. BP will differ only by year of manufacture of the car. That is, the mounting blocks for the carburetor and injector are the same. The VAZ 2109-099 fuse box (carburetor, injector) is located under the hood, in the compartment in front of the windshield on the left side.

Fuse block 2114-3722010-18

K1-relay for turning on headlight cleaners; K2-relay-breaker for direction indicators and hazard warning lights; K3 - windshield wiper relay; K4-relay for monitoring the health of lamps; K5-power window relay; K6 - relay for turning on sound signals; K7-relay for turning on the electric heating of the rear window; K8-relay for high beam headlights; K9-relay for low beam headlights; F1-F16 - fuses.

Fuse block 2114-3722010-60

K1 - Headlight wiper relay, K2 - Turn signal and hazard warning relay, K3 - Windshield wiper relay, K4 - Brake light and parking light relay, K5 - Power window relay, K6 - Horn relay , K7 - Rear window heating relay, K8 - Headlight high beam relay, K9 - Headlight low beam relay, F1 - F16 - Fuses, F1 - F20 - Spare fuses.

Attention! The power terminals on the generator often become loose, heat up, spark and melt the wiring. Pay attention to this point when searching for possible faults yourself.

Engine tuning

• direct-flow exhaust system - spider circuit 4/2/1 and resonator with banks;
• sports camshaft – gas distribution modes change.

Tuning 2108

Tuning is usually used to add about 10 horsepower. With. by replacing the carburetor with an injector or a direct-flow muffler. There is a time-consuming option to replace the crankshaft with the following crank diameter. The piston stroke increases by 2 mm, but a KShG kit, precise calculation and adjustment of the mechanism are required.

Thus, the 2108 engine uses advanced technologies from the German automobile industry. The weight and dimensions of the engine have been reduced for transverse placement under the hood of a front-wheel drive car. In two versions, 1.1 l and 1.5 l, the modernization was carried out by employees of the manufacturer's plant.
