Injector power unit, which is installed on the VAZ 2115, has an electronic control unit. In order to adjust the functioning of the engine, the electronics constantly monitors the changes that work is accompanied. Sensors are used for this. About this further in the article.

VAZ Sensor Panel 2115

The VAZ 2115 sensor panel includes the following instruments:

• Speedometer. Shows the driver of the current velocity velocity vehicle. The speedometer receives information about the velocity of the car due to the sensor, which is on the checkpoint.
• Tachometer. Located to the left of the speedometer. It is an electronic device receiving signals from the BC and reflecting the current crankshaft turns.
• Fuel level pointer. It is located to the right of the speedometer. Shows the amount of fuel in the tank.
• Level pointer Co. Reports the temperature of the coolant. The pointer is to the left of the tachometer. Information comes from the corresponding sensor.

Temperature sensor VAZ 2115

Dzuz differs simplicity of design and durability. The only task is to track the temperature changes of the coolant. The electronic unit uses information obtained from the sensor to adjust the crankshaft speed and the ratio of the air and fuel mixture, as well as to select the ignition advance angle.

Idling sensor VAZ 2115

The idling sensor is not only an instrument for reading indicators, but also by an adjusting device that directly affects the operation of the motor at idle.

This unit has an electric drive, as well as a conical needle that is part of the throttle pipe. Under conditions of idle speed, the LCH changes the position of the needle, closing or opening the nozzle, which adjusts the amount of air that is supplied to the throttle node.

VAZ Speed \u200b\u200bSensor 2115

Information about the current velocity of the vehicle speed sensor transmits by pulse signals. Depending on the frequency of these signals, the electronic unit determines the velocity of the vehicle.

The information obtained is used to adjust the rotor speed at idle. When the speed sensor breaks, the fuel consumption is significantly increased at idle, the speedometer does not work and the engine cras.

Oil Sensor VAZ 2115

The oil pressure sensor is designed to communicate the motorist about breakdowns in the oil system. More precisely, it fixes that the pressure fell in the system, reporting a car owner through the emergency pressure lamp, which is located in the cabin on the instrument panel.

VAZ 2115 crankshaft sensor

DKPB is a device that serves in the electronic unit information about the position of the crankshaft. The correct functioning of the injector motor nozzles, the ignition system and the supply system of the fuel mixture depends on the operation of this node.

This device is not rarely called synchronization sensor, since it is based on the data obtained from the DCPV, the electronic unit determines the moment of fuel injection into the cylinder of the power unit. When this sensor breaks into the brain, the car will be submitted incorrect information and the power unit will lose its performance, since malfunction will occur in the fuel supply system, and nozzles will not be able to function correctly. There is a DCPV near the camshaft, near the generator belt.

Air Sensor VAZ 2115

Thanks to the information obtained with DMRV, the electronic unit regulates the optimal ratio of gas and gasoline in the fuel mixture, which is supplied to the engine nozzles. If the device works incorrectly, the combustible mixture will not respond to the requirements of the current mode of operation of the engine, which entails the reduction in power and deterioration of the dynamics, as well as increased fuel consumption.

Fuel Sensor VAZ 2115

The fuel level sensor is designed to control the level of fuel in the car's tank. If, when you start the battery, it shows that the tank is empty, and after the start of the reading, the readings are changing, you must replace the sensor. Replacement is also needed if the device does not respond when you refuel (shows an empty tank).

Detacon Sensor VAZ 2115

A properly working detonation sensor is the key to the normal functioning of the VAZ engine. With his breakdown, the motor will trim, and fuel consumption will increase. The detonation sensor responds to the vibration of the power unit, information about which is transmitted to the electronic unit, which allows the computer to choose the correct ignition advance angle. The device is attached to the cylinder block near the fan.

Oxygen Sensor VAZ 2115

Lambda probe, he is an oxygen sensor, transmits an information about the amount of oxygen content in exhaust gases. It is located in the receiving exhaust pipe collector, near the resonator.

VAZ 2115 fan sensor

This sensor is located in the stove radiator. Inside it is a special contact group. When the coolant in the radiator heats up, this group is also heated and expands. And when this extension comes to the desired limit, the contacts are closed, the signal is transmitted to the wiring and the fan is turned on.

Phase sensor VAZ 2115

The phase sensor transmits to the electronic unit information about the current engine function cycle: which open valve is open and which is currently implemented as the gas distribution phase. Based on the data obtained, the electronic unit determines the fuel injection point in such a way that the fuel is supplied directly before opening the inlet valve. The device is on the engine, near the GBC, not far from the air filter.

Throttle Sensor VAZ 2115

DPDZ is one of the key devices, the correctness of which affects the operation of the fuel system. This sensor transmits information to the brain information, at what angle at least the throttle is currently located.

One of the main characteristics of the DPDZ is the frequency of the signal. Based on the signal frequency changes, the motor control unit determines the degree of pressing on the gas mission, which allows "brains" to select the most optimal cooling mode and the amount of fuel supplied.

VAZ 2115 reverse sensor

The only function of the reverse sensor is to turn on the rear white lights when the driver drops back. The signal that gives the sensor on white lights, reports to other participants in the movement, that the driver is touched back either already moved and moves in the rear. And in the dark for your convenience, these white lights highlight the way back, informing the rest of your intentions.
