Idle speed control

The idle speed regulator, also known as IAC, is installed in the throttle valve. Designed to regulate idle speed on engines without the E-GAS system. The sensor is quite unreliable and fails very often. It is a motor with a worm gear. If there is a malfunction, the “CheckEngine” light does not light up.

Signs of malfunction:

• Not smooth idle;
• The revolutions are floating;
• Troubles the engine;

Oil pressure sensor

The oil pressure sensor is installed in the cylinder head. Designed to indicate oil pressure and indicate oil pressure when the engine is running. A very reliable sensor that rarely fails. The “CheckEngine” light does not light up when there is a malfunction.

Signs of malfunction:

• The oil pressure light is constantly on;
• The oil pressure light does not light up when the ignition is turned on;

Crankshaft position sensor

Crankshaft position sensor, also known as DPKV. Installed on a bracket near the generator belt drive pulley. Works on the law of electromagnetic induction. Reads readings from the crown of the generator drive pulley. Sets the ignition timing angle (IAF). If there is a malfunction, the “CheckEngine” light comes on.

Signs of malfunction:

• The engine runs intermittently;
• The engine does not start (no spark);

Throttle Position Sensor

The throttle position sensor (TPS) is installed on the throttle valve on cars without the E-GAZ system. Designed to regulate engine speed. The sensor is not reliable and often fails. If there is a malfunction, the “CheckEngine” light does not always light up.

Signs of malfunction:

• Not smooth idle;
• The revolutions are floating;
• Troubles the engine;
• When starting the engine, the speed is increased;
• Spontaneous increase or decrease in speed;

Knock sensor

The knock sensor is installed on the cylinder block under the intake receiver. Based on the principle of the piezo element. Engine detonation is measured and the air-fuel mixture is adjusted. Quite a reliable sensor. If there is a malfunction, “CheckEngine” does not light up.

Signs of sensor malfunction:

• Loss of vehicle dynamics;
• Unstable idle;
• Jerking when moving;

Phase sensor

The phase sensor is installed on an engine with 16 valves, located near the fuel rail. Based on the law of electromagnetic induction, it takes readings from the intake camshaft master pulley. Participates in the process of formation of the air-fuel mixture for each cylinder separately. In the event of a malfunction, the engine begins to operate in emergency mode. When there is a malfunction, the “CheckEngine” light almost always comes on.

Signs of malfunction:

• The engine runs intermittently;
• Increased fuel consumption;
• Unstable engine operation at idle;

Oxygen sensor

The oxygen sensor is installed in the exhaust manifold of the car. Serves to monitor exhaust gases and adjust the air-fuel mixture. A reliable sensor rarely fails. If there is a malfunction, the “CheckEngine” light does not always light up.

Signs of sensor malfunction:

• Loss of vehicle dynamics;
• Unstable idle;
• Jerking when moving;
• Difficulty starting the engine;
• High fuel consumption;
• Black smoke when driving at high speeds;

Speed ​​sensor

The speed sensor is installed on the gearbox housing and is designed to measure the speed of the vehicle and calculate the kilometers traveled. The speed sensor also provides readings for preparing the air-fuel mixture while the car is moving. You can notice that when the car is rolling at neutral speed, the idle speed is slightly higher than when the car is stationary. When there is a malfunction, the “CheckEngine” light almost always comes on.

Signs of sensor malfunction:

• There are no increased speeds when driving at neutral speed;
• Speedometer does not show speed;
• The odometer does not work;
• EUR does not work;

Scheme VAZ-2170 - VAZ-21728 Lada Priora

Complete information is provided about electrical equipment, wiring, relays and fuses of VAZ-2170 - VAZ-21728 vehicles. The collection is intended for auto electricians and those who, having some knowledge of circuit design, can carry out minor auto repairs with their own hands. The Lada Priora sedan (VAZ-2170) has been produced since 2007, the VAZ-2172 hatchback since 2008, and the VAZ-2171 station wagon has been produced since 2009. In 2013, the car was modernized and they began installing an AMT robotic gearbox (21723, 21728).

There are 4 main harnesses in the Priora electrical circuit:

• from the instrument panel;
• providing motor control;
• front electrical harness;
• rear electrical harness.

All these harnesses are connected to each other using detachable connections. The connectors are located under the dashboard. Each of the harnesses is assigned a serial number.

In addition to the main ones, there are also secondary ones:

• installed in the front passenger door;
• identical in both the left and right rear doors;
• installed in the driver's door;
• connecting the backlight of the license plate;
• connecting the electrical package.

Each element in the diagram corresponds to a number with an explanation. Since all elements are standardized, their designations are identical on car diagrams of all car manufacturers. Next to each electrical appliance, the connectors that go to them are indicated. The pins or sockets of the pads are also numbered.
