VAZ-2115, 2114 with ECM based on controller M 7.9.7 (analogous to January 7.2) EURO-2

Repairs on a forced 1.6-liter engine are a little more complicated: First you need to remove the protective casing and loosen the clamp securing the air filter pipe.

Removing the sensor from the car The idle speed regulator is located in the mounting hole of its unit, that is, the throttle. Fuse 1 provides constant power to the electrical package control unit.

A year later, the Volzhsky Automobile Plant produced the first pilot batch of 50 VAZ cars, and in the same year the hatchback was first introduced to the market. If you removed the sensor from the car, but the engine operation does not change, then that was the reason. Timing marks 8 class VAZ! Installation of timing belt 8kl.VAZ2108,2109,2110,2111,2113,2114,2115

To do this: Remove the wire tip from the spark plug of the first cylinder; We bring it to the metal part of the motor at a distance of mm; Turn on the starter; Let's see if a spark jumps between the wires; Similarly, we check the wires from spark plugs 2, 3 and 4 of cylinders. Advice: if you want to understand the operation of a car’s ignition and power system, it would be a good idea to watch video materials from a school physics course.

The search starts with: Ignition module; ECU - on cars with a VAZ engine To check the ignition coil, you need to use a tester, with which you should measure the resistance of the primary and secondary windings. Once you understand it and understand the principle of operation, you can effectively drive your car and perform minor repairs.

Front harness diagram for VAZ 2114 injector

The VAZ ignition module consists of a two-spark coil and is of the block type. The interior of the VAZ car has become more comfortable, a new, more convenient and advanced instrument panel has appeared, which has a more streamlined and ergonomic shape, backlit push-button switches and indicator lamps, etc. In the instrument panel wiring harness, the second ends of the white wires are brought together into one point, which is connected to the switch lighting of devices except for the white wire, from plug “4” of block “X2” of mounting block 28 to block 83 of the on-board control system indication. The fuel supply is considered distributional, because gasoline is injected into each cylinder using a specific injector. The first coil supplies an impulse to the 1st and 4th cylinders, and the second - to the 2nd and 3rd cylinders.

Connecting the adsorber valve to the injection system controller also provided another additional element.

Good luck on the roads! Injector connection diagram It is quite difficult to describe in words the pinout of the wires connecting the injector to the ignition system, so you should pay attention to the diagram below.

Based on the location of the rod, the volume of air that enters through the calibration hole will also change. It is possible to connect fog lights.

We discard the wires leading to the sensor. We spread the ignition wires

In fact, the VAZ 2114 wiring is always connected to fuses. Such fuses do not protect only the circuit of the generator and charging device, the mechanism for switching on the power unit of the machine, as well as the winding of the backlight cut-off relay.

Before replacing a failed electrical circuit fuse, you need to find out exactly the reasons for the wiring overload, as well as its elimination. Finding the cause will be much easier if you first read the following materials. Below is a list of fuses and their purposes.
