Connection diagram for oil pressure indicator VAZ 2106

In front-wheel drive VAZs, unlike the “classics”, there is no oil pressure indicator, but only an emergency low oil pressure lamp. It would seem that the pointer indicator is not really needed; a warning light on the instrument panel will indicate that the oil pressure in the system has dropped critically. But for those who once drove a classic, the pointer indicator may not be enough. And it’s just nice for some to realize that he controls the operation of all car systems to the fullest extent.

Therefore, in this article we will look at how to display engine oil pressure readings on the instrument panel of a VAZ 2109.

For this we need:

— Sensor adapter from VAZ 2106 – fitting and tee, with two copper washers:

— Sensor for pointer device:

— The indicator itself is from a VAZ 2106, installed in the cabin:

The oil pressure sensor on a 1.5 liter 8-valve Nine engine is located on the cylinder block on the side facing the passenger compartment in the area of the timing case.

We unscrew the standard sensor, screw in an adapter (with a tee) in its place, and screw back into the tee the standard emergency oil pressure sensor and the “six” sensor onto the pointer indicator. Don’t forget to install copper washers, having previously calcined them over a fire to give them softness and ductility. Tighten all connections tightly.

Now our device needs to be connected. To do this, you need to run a wire from the sensor on the engine into the cabin, to the place where the indicator is installed. There are 5 contacts on the sensor from the VAZ 2106; they must be connected as in the figure:

You can install the pressure indicator itself instead of the headlight hydraulic corrector - few people use it, and few places it works. You can choose another place as you prefer.

Here are installation examples:

That's it, now our car is equipped with an oil pressure indicator, you can use it.

Oil pressure sensor BAZ 2106 and its connection

When you drive a VAZ 2106, especially over long distances, you need to monitor all the systems of your car, especially the oil pressure, because if there is oil starvation, the engine will quickly come to an end. As you understand, today we will talk about the VAZ 2106 oil pressure sensor.

So, you need to monitor the oil pressure while the engine is running; if the pressure is lower or higher than normal, then this situation should give reason to think about it. The VAZ 6 has an oil pressure sensor, which in most cases works properly, it has an arrow and even a warning light.

Price and article

At the moment, there are several oil pressure sensors for the VAZ-2106 from different manufacturers. Below is a table of the most common of them, which shows the name of the sensor, the article number and its price.

Sensor	vendor code	Cost, in rubles
Oil pressure sensor VAZ 2101/ 2102/ 2103/ 2104/ 2105/ 2106/ 2107	21063829	100
Oil pressure sensor(BCG)	MM393	150
Oil pressure sensor(FKQ) Vernet	OS3518	150
Oil pressure sensor ERA	330566	140

How the VAZ 2106 oil pressure sensor works and works

The design of the oil pressure sensor on the VAZ 2106 is quite simple, so, in general, it is reliable. The principle of its operation is that deformations are read from an elastic membrane. The membrane itself, under the influence of oil, deviates from its initial position. The distance by which the membrane has moved is fixed by the resistor, it is also called a variable rheostat. Each change in resistance is transmitted to a pressure gauge with an arrow.

To transmit a signal from the motor to the instrument panel, the following elements are used:

oil sensor;
temperature compensation and variable resistors;
a magnet that returns the arrow to its original position;
warning lamp;
windings;
fuse.

The VAZ 2106 oil pressure sensor and all other elements are powered by the battery after the ignition is turned on. If the pressure sensor breaks, it is easier to simply replace it with a new one than to try to repair it. Firstly, it is not expensive, and secondly, after repair it may show incorrect indicators.

The pressure sensor operates in the range: 0.2 kgf/sq. cm. – 0.6 kgf/sq. cm. If you convert to MPa, you get 0.02 - 0.06. If the pressure in the oil line corresponds to this range, then the contacts of the sensor are open. If suddenly the pressure in the line is higher or lower than the specified range, the sensor contacts will close, after which the warning light will immediately light up.

The model of this oil pressure sensor is MM393A, it is installed on VAZ 2106, 2121 and some of their modifications.

Sensor design features

The sensor has a pointer and a signal light; it is a very convenient and reliable design. Under the influence of oil, the elastic membrane is deformed, the shift value is recorded using a resistor, and the change in resistance is sent to the pressure gauge. System functionality is ensured by:

oil sensor;
resistance;
magnet;
coil;
signal light;
fusible insert.

The power turns on when the key is turned in the ignition. When a sensor stops working, it is not cost-effective to repair it, since once reassembled there is a high probability that the indicator will show incorrect information. The device is inexpensive, so if it breaks, it is better to replace it with a new one.

Engine oil should be selected based on the type of engine and its condition. For the VAZ 2106, lubricant mixtures are ideal for use with gasoline engines. Before buying motor oil, read the instructions for your “six”. It lists all the names and brands of various process fluids necessary for operating the car.

If you are the owner of an old car and there is no technical documentation, then before purchasing engine oil, you need to accurately determine whether the valve clearance adjustment system has hydraulic compressors, and whether the engine parts are compatible with synthetic oils.

On VAZ 2106 car models that came off the assembly line before the 80s, rubber valve stem seals are installed, which are not compatible with synthetic motor oils. They can be replaced with products made from acrylate or fluorine rubber.

How to check whether the VAZ 2106 oil pressure sensor is working properly

If you suddenly notice that the oil pressure has dropped to 0 and even the lamp comes on, this does not mean that it is time to panic. The point may be that the VAZ 2106 oil pressure sensor itself is not working correctly, despite the fact that everything is in order with the engine. First you just need to turn off the engine.

Open the hood and see what’s there: if there are no oil drips, then you should check the oil level in the engine using a dipstick. If the oil is low, it may be because the oil line pressure is low.

To understand the reason, you need to diagnose the sensor in a garage or at a service station - take a pressure gauge whose measuring range coincides with the range of the oil pressure sensor. You also need to remember that the thread at the connection point of the VAZ 2106 sensor has the following designation: M14x1.5. This means that the diagnostic device must also have these parameters, or you can select an adapter with this designation.

To remove the oil sensor you will need an open-end wrench. These steps must be performed with the engine turned off. Instead of the sensor, a pressure gauge is installed, then you need to turn on the engine and see what the actual oil pressure in the line is.

Next, you can press the gas pedal, after which the engine speed will increase, and see what the maximum oil pressure is. If the pressure gauge shows that everything is normal, then you just need to change the pressure sensor. If not, then look for the problem further.

What you can do yourself

The problem of low oil pressure greatly complicates the relationship between lubricant consumption and level drop and the overall pressure in the system. In this case, a number of malfunctions can be eliminated independently.

If leaks are detected, the problem is quite easy to localize and solve. For example, oil leakage from under the oil filter can be eliminated by tightening or replacing it. The problem with the oil pressure sensor, through which lubricant flows, is solved in a similar way. The sensor is tightened or simply replaced with a new one.

As for seal leaks, in this case you will need time, tools and skills. In this case, you can replace the front or rear crankshaft oil seal with your own hands in your garage with an inspection hole.

Oil leaks from under the valve cover or in the pan area can be eliminated by tightening fasteners, replacing rubber gaskets, and using special engine sealants. Violation of the geometry of the connecting planes or damage to the valve cover/pan will indicate the need to replace such parts.

If the coolant gets into the engine oil, then you can remove the cylinder head yourself and replace the head gasket, while following all the recommendations regarding the removal and subsequent re-covering of the cylinder head. An additional check of the mating planes will indicate whether the cylinder head needs to be ground. If cracks are found in the cylinder block or head, repairs are also possible.

In the case where the problem in the lubrication system is not so obvious, and you have to repair the car yourself, then at the very beginning you should measure the oil pressure in the engine.

To solve the problem, as well as taking into account an accurate understanding of where the oil pressure in the engine is measured and how it is done, additional equipment must be prepared in advance. Note that there is a ready-made device for measuring engine oil pressure available for free sale.

How to install a new oil pressure sensor on a BAZ-2106 or other cars

There are drivers who do not like the sensors that are installed on later VAZ models. For example, on 8s and 9s it makes sense to install an oil pressure sensor from a VAZ 2106. The procedure for replacing the sensor is quite simple, and anyone can handle it.

First you need to buy a new sensor with an indicator and wires. An adapter is also needed that will connect the new system to the cylinder block.
The 9 or 8 does not have room for a pressure indicator, unlike the 6. Some owners replace the headlight range control knob, which does not work, with a sensor indicator. And for those whose headlight range control knob works, it makes sense to cut a special socket in the instrument panel to accommodate the oil pressure sensor indicator. Such a nest can be made with an electric drill with a thin drill. The holes must be drilled in a pre-marked circle, then using a round file, adjust the location for the VAZ 2106 oil pressure sensor. An adapter with a copper O-ring must be placed in the place where the standard sensor was located. Then you need to attach the sensor from the VAZ 2106 through this copper ring.
Next, you need to connect the dial indicator to the sensor using wires.

But this is for those who really liked the oil pressure sensor from the 6. Of course, a simple system, clear instruments that show exactly what pressure is in the oil line, and if the sensor breaks down, you can simply throw it away and install a new VAZ 2106 oil pressure sensor yourself; it is not at all expensive - about 300 rubles.

And then a video on how to distinguish a high-quality sensor from a fake:

Concept and purpose ↑

The oil pressure indicator is designed to read the atmospheric pressure in the pipeline and display the indicators on a mechanical sensor. New models are equipped with a digital device, with many related functions. Directly in the VAZ, the device is located at the rear of the engine on the left side.

It is enough to get a flat platform with free access on the sides. We don’t need an inspection hole or a roadside overpass;
We will prepare a set of automotive tools, rags, and a new sensor. You can purchase the device at any auto store or car market. The cost is cheap, even by modern standards;
turn off the vehicle, release the handbrake;
open the hood, use the fatal 19 key to unscrew the sensor itself, disconnect the terminal blocks of the electrical wires from it;
We install new equipment in place of old, non-working equipment. We carry out the assembly procedure in reverse order;
We start the engine, look at the readings, and check that the markings match. If the wrong sensor is installed, inaccurate readings may occur. The driver may receive data that does not correspond to reality.

Installing the oil pressure gauge

Therefore, in this article we will look at how to display engine oil pressure readings on the instrument panel of a VAZ 2109.

For this we need:

— Sensor adapter from VAZ 2106 – fitting and tee, with two copper washers:

— Sensor for pointer device:

— The indicator itself is from a VAZ 2106, installed in the cabin:

The oil pressure sensor on a 1.5 liter 8-valve Nine engine is located on the cylinder block on the side facing the passenger compartment in the area of the timing case.

Late model cars

It has already been said that on the VAZ-2106 the oil pressure sensor allows for broader control. Starting with the first Samara, VAZ installed slightly different designs that could not satisfy some groups of drivers. It is clear that an illiterate driver, seeing an image of a red oil can, may not even suspect that something is wrong. And where does he care about monitoring the pressure in the system?

But most motorists are technically savvy, for this reason it is necessary to be aware of everything that happens to the engine. In “Samara” and “tens”, for example, there is a chic attribute - headlight range control. Moreover, it is hydraulic. And finding a car with a working corrector mechanism is impossible even during the day. But this is a free niche; a pressure indicator can be easily installed in it. And instead of the standard sensor, an adapter is mounted. The engine oil pressure sensor becomes the same as on the “classic”. And simple wiring is laid, which is powered from the ignition switch and connects all elements of the system.

Purpose of the oil pressure control sensor

All moving and rubbing parts of the power unit are constantly washed with liquid lubricant supplied by a gear pump from the engine sump. If, for various reasons, the supply of lubricant stops or its level drops to critical, the motor will face a serious breakdown, or even more than one. The result is a major overhaul with replacement of the crankshaft bearings, cylinder-piston group, and so on.

To protect the car owner from these consequences, classic Zhiguli models provide two-level control over the engine lubrication system, operating according to the following algorithm:

After turning the key in the lock and turning on the ignition, the red warning lamp lights up, indicating a lack of oil pressure. The pointer needle is at zero.
In the first 1-2 seconds after starting the engine, the indicator continues to light. If the oil supply is normal, the lamp goes out. The real pressure created by the pump is immediately shown by the arrow.
When the engine turns off, a large amount of lubricant is lost, or a problem occurs, the red indicator lights up immediately.
If the lubricant pressure in the motor channels decreases to a critical level, the light begins to flash periodically.

Malfunctions leading to a drop in pressure - breakdown or wear of the oil pump, complete wear of the crankshaft liners or breakdown of the crankcase.

The main role in the operation of the system is played by the sensor - an element that records the oil pressure in one of the main channels of the engine. The indicator and pointer are just a means of displaying the information transmitted by the pressure meter.

Fuel level

On the “sixes” a fuel level indicator of the BM-150 type is installed, the controller itself is mounted in the gas tank according to the scheme, and it is fixed with bolts. The FLS includes a resistor device and a float. In order for the controller to indicate the correct level of gasoline in the system, a resistor device is controlled by the movement of the float.

The fuel level indicator float itself is directly connected to the resistor using a lever, at the end of which there is a sliding element. Thanks to the latter, the gasoline reserve lamp on the dashboard can light up. If the controller adjustment is correct, then this light comes on when there are 5-6 liters of gasoline in the tank.

The controller diagnostic procedure is carried out by measuring the resistance level of the resistor device. If the gas tank is empty, this parameter should be about 315-345 Ohms, if it is half full - 108-128 Ohms, if full - about 70 Ohms. Diagnostics is carried out using a combined tester (the author of the video is VAZ 2101-2107 REPAIR AND MAINTENANCE).

As for the temperature indicator, the VAZ 2106 uses a TM-106 type device; this regulator is also often called a fan switch sensor. The controller itself is made in the form of a screw, which is connected to the cylinder block. As for the operating principle of the temperature sensor or fan sensor, it is similar to that described above. But only in this case is a thermistor element installed, which changes the resistance parameter depending on the temperature of the consumable material.

The correct operation of the engine depends on the fan switch on sensor, because if the temperature is too high and the fan does not start working, this will lead to overheating of the motor. There is an engine temperature indicator on the car dashboard, allowing the car owner to always know about its condition.

JOT and the fan switch on sensor on a carburetor machine are two different sensors, and on an injection machine there is one sensor.

Six DTOZH

Location and appearance of the device

The sensor installed on classic VAZ 2106 models consists of the following parts:

an element in the form of a round metal barrel with one terminal for connecting a wire (factory name - MM393A);
the second part is a membrane switch in the form of a nut with a contact at the end (designation MM120);
a steel tee into which the above parts are screwed;
sealing bronze washers.

The large “barrel” MM393A is designed to measure pressure, the “nut” with the MM120 terminal fixes its absence, and the tee is a connecting element that is screwed into the engine. The location of the sensor is on the left wall of the cylinder block (if you look in the direction of movement of the car) under spark plug No. 4. Do not confuse the device with the temperature sensor installed higher in the cylinder head. Wires leading inside the cabin, to the dashboard, are connected to both contacts.

In later models of the “classic” VAZ 2107, the indicator arrow on the dashboard is missing, only a warning lamp is left. Therefore, a stripped-down version of the sensor is used without a tee and a large barrel.

Main aspects of the operation of sensors on the domestic “Six”

Any modern car is equipped with various regulators and controllers designed to monitor the condition of the components and assemblies of the car. Even the old domestic “sixes” in this case are no exception. You can learn more about what the oil pressure, fuel level, antifreeze temperature sensor is on the VAZ 2106 from this article.

Device and connection diagram

The task of the membrane switch, made in the form of a nut with a terminal, is to promptly close the electrical circuit with the warning lamp when the lubricant pressure drops. The device consists of the following parts:

metal body in the form of a hexagon;
contact Group;
pusher;
measuring membrane.

The element is connected to the circuit according to the simplest circuit - in series with the indicator. The normal position of the contacts is “closed”, so after turning on the ignition the light comes on. When the engine is running, there is a pressure of oil flowing to the membrane through the tee. Under the pressure of the lubricant, the latter presses the pusher, which opens the contact group, as a result the indicator goes out.

When one of the malfunctions occurs in the engine, causing a decrease in the pressure of the liquid lubricant, the elastic membrane returns to its original position and the electrical circuit is closed. The driver immediately sees the problem by the flashing “control”.

The design of the second element, the “barrel” called MM393A, is somewhat more complicated. The main role here is also played by an elastic membrane connected to an actuator - a rheostat and a slider. The rheostat is a coil of high-resistance chromium-nickel wire, and the slider is a movable contact that moves along the turns.

The electrical circuit for connecting the sensor and pointer is similar to the first one - the rheostat and the device are in series in the circuit. The operating algorithm is as follows:

When the driver turns on the ignition, on-board voltage is supplied to the circuit. The slider is in its extreme position, and the winding resistance is maximum. The instrument needle remains at zero.
After starting the engine, oil appears in the channel, flowing through the tee into the “barrel” and pressing on the membrane. It stretches and uses a pusher to move the slider along the winding.
The total resistance of the rheostat begins to decrease, the current in the circuit increases and causes the indicator arrow to deviate. The higher the lubricant pressure, the more the membrane stretches and the less resistance of the coil, and the device notes the increase in pressure.

The sensor reacts in the reverse order to a decrease in oil pressure. The force on the membrane decreases, it is thrown back and pulls the slider with it. He turns on new turns of the rheostat winding in the circuit, the resistance increases, and the instrument needle drops to zero.

Reasons for the glowing indicator. Remedies

There are several reasons why the indicator light is on. Let's look at each one separately and how to eliminate them.

Insufficient level

It is quite possible that the engine oil level is insufficient. Every VAZ car owner knows how to check. It is necessary to top up to the permissible level and re-check with starting the internal combustion engine.

Checking the level is carried out on a cold engine or 10 minutes after it has been running.

Internal fault

To check the sensor, you must perform the following steps:

Turn on the ignition.
Make sure the indicator lights up.
Disconnect the wire from the sensor. The indicator should go out.
“Lock” it with the engine housing. If the indicator on the dashboard lights up, then the wire is working and the cause of the malfunction is in the sensor. It cannot be repaired and should be replaced.

Wiring fault

During vehicle operation, electrical wiring is often exposed to high temperatures, friction with metal parts, drying out, and loss of integrity.

The check is carried out according to the electrical diagram of the VAZ 2107 car using a multimeter for conductivity and resistance of the wire.

Wear of engine parts

During operation of the internal combustion engine, oil circulates through its piston system and gas distribution mechanism through special channels. If the rubbing parts wear out, the tightness and alignment of these channels is disrupted. Due to this, the pressure drops.

The solution to this problem is to overhaul the engine.

Pump fault

In this case, the oil pressure in the line is checked using a pressure gauge.

A pressure gauge must be screwed into the technical hole in the internal combustion engine cylinder block for the sensor and the internal combustion engine must be started. At idle speed the value should be about 1.5 kg/cm2. As the engine speed increases, the pressure should increase, reaching 5–6 kg/cm2.

How to check and replace an element

During long-term operation, the internal parts of the sensor wear out and periodically fail. The malfunction manifests itself in the form of false readings on the indicator scale or a constantly burning emergency lamp. Before drawing conclusions about power unit failures, it is highly advisable to check the functionality of the sensor.

If the control light comes on while the engine is running and the indicator drops to zero, your first action is to immediately turn off the engine and do not start it until the problem is discovered.

When the light comes on and goes out in a timely manner, and the needle does not deviate, you should check the serviceability of the oil sensor - the MM393A pressure meter. You will need a 19 mm open-end wrench and a pressure gauge with a scale of up to 10 Bar (1 MPa). A flexible pipe with a threaded tip M14 x 1.5 must be screwed to the pressure gauge.

The verification procedure is as follows:

Turn off the engine and let it cool to 50-60 °C so you don’t have to burn your hands while working.
Disconnect the wires from the sensors and unscrew them with a 19 mm wrench along with the tee. Please note that during disassembly a small amount of oil may leak out of the unit.

On the road, it is more difficult to check the VAZ 2106 oil sensor, since there is no pressure gauge at hand. To make sure there is lubricant in the engine channels, unscrew the element, disconnect the main ignition wire and rotate the crankshaft with the starter. If the pump is working properly, oil will splash out of the hole.

If the arrow on the instrument scale shows normal pressure (in the range of 1-6 Bar), but the red lamp is on, the small MM120 membrane sensor has clearly failed.

When the light signal does not light up at all, consider 3 options:

the light bulb burned out;
broken wiring;
The small sensor in the form of a hexagon has become unusable.

The first 2 versions can be easily checked by testing them with a tester or multimeter. The serviceability of the membrane element is tested as follows: turn on the ignition, remove the wire from the terminal and short it to vehicle ground. If the lamp lights up, feel free to change the sensor.

Replacement is done by unscrewing the large or small sensor with a wrench. It is important not to lose the bronze sealing washers, since they may not be included with the new part. Remove any leaks of engine lubricant from the hole with a rag.

Both meters cannot be repaired, only replaced. Their metal cases, capable of withstanding the oil pressure of a running engine, are hermetically sealed and cannot be disassembled. The second reason is the low price of VAZ 2106 spare parts, which makes such repairs pointless.

How to diagnose

It is unlikely that you want to get into an expensive engine overhaul. For this reason, you need to monitor the operating mode of the engine, in particular, the pressure value in the lubrication system. If it is insufficient, then the oil will not be able to reach the most distant corners. For example, the camshaft and valves will not be sufficiently lubricated. It is quite possible that the latter may knock, as if shouting for help.

Checking the performance is a guarantee that you will not have any unpleasant “surprises”. To check, you need an accurate pressure gauge with a scale of up to 10 atmospheres (this is more than enough). Remove the oil pressure sensor on the VAZ-2106 and turn on the pressure gauge instead. But there will be small subtleties, depending on what type of pressure gauge you chose - electric or dial. The second one is easier. Start the engine, the arrow should deviate slightly. There should be two atmospheres at 2000 rpm of the crankshaft. True, sometimes there is too much. Regardless of the crankshaft speed, the pressure should not exceed seven atmospheres.

Pointer functions and operation

The purpose of the device, built into the dashboard to the left of the tachometer, is to display the engine oil pressure level, guided by the sensor. The principle of operation of the pointer resembles the operation of a conventional ammeter, which responds to changes in current strength in the circuit. When the mechanical rheostat inside the measuring element changes resistance, the current increases or decreases, deflecting the needle. The scale is graduated in pressure units corresponding to 1 Bar (1 kgf/cm2).

The device consists of the following main elements:

round body;
pointer mechanism with permanent magnet and windings;
a control light connected to the corresponding sensor by a separate line;
scale with backlight;
compensation resistor;
connecting wires with connector.

Zero readings of the device correspond to a circuit resistance of 320 Ohms. When it drops to 100-130 Ohms, the needle stays at 4 Bar, 60-80 Ohms - 6 Bar.

The Zhiguli engine lubrication pressure indicator is a fairly reliable element that breaks very rarely. If the arrow does not want to leave the zero mark, then the culprit is usually the sensor. When you doubt the functionality of the indicating device, check it using a simple method: measure the voltage at the connection contacts of the MM393A oil sensor with the engine running. If voltage is present and the needle is at zero, the device should be changed.

The VAZ 2106 oil pressure monitoring system with two sensors and a mechanical indicator is simple and reliable in operation. Despite the outdated design, car enthusiasts often buy and install these meters on other, more modern cars, equipped from the factory with only a control indicator. Examples are the updated VAZ Seven, Chevrolet Aveo and Niva.

Characteristics

The indicator of this type of sensor shows approximate values, but this is quite enough to determine the “health” of the engine. If the lubricant is in the oil line under critically low pressure, then this device closes the electrical circuit of the warning lamp located on the dashboard of the car, and the arrow will deviate to the left.

Among the main characteristics of the VAZ 2106 oil pressure sensor, the most important are:

Working pressure: 0–8 kgf/cm².
Electrical resistance: 290–320 Ohms.
Fitting thread: M14×1.5
Weight: 185 g.
Size: 40×80 mm.

Another important parameter of this type of sensor is the pressure value at which the warning light lights up. For the VAZ 2106 engine, the contact closure of the control device is set to a value of 0.5 kgf/cm².

How to check the oil pressure sensor on a VAZ 2106, connection diagram and replacement, instructions with photos and videos

Therefore, in this article we will look at how to display engine oil pressure readings on the instrument panel of a VAZ 2109.

For this we need:

The oil pressure sensor on a 1.5 liter 8-valve Nine engine is located on the cylinder block on the side facing the passenger compartment in the area of the timing case.

You can install the pressure indicator itself instead of the headlight hydraulic corrector - few people use it, and few places it works. You can choose another place as you prefer.

Here are installation examples:

That's it, now our car is equipped with an oil pressure indicator, you can use it.

Lamp switch sensor

Take a look at the instrument panel of the VAZ-2106, you will see an indicator with an arrow and a warning lamp. It signals that the pressure in the lubrication system has dropped to a critical value. And this lamp operates from a separate reading device, which is located in close proximity to the pressure sensor. If this lamp does not light, the reader must be replaced.

To do this, you need two tools - a 21 socket and an open-end wrench of the same size. The first step, of course, is to disconnect all wires that may interfere with removal. Why do you need two keys? You hold the metal adapter with one so that it does not turn. And with the second you unscrew the body of the device. Install the new one in reverse order. This completes the work, replacing the oil pressure sensor was successful.

according to the diagram everything is correct. I already thought that my memory had failed me in my old age, but no! the diagram is 100% correct. I checked. Most likely the sensor is buggy.

Remove the wire from the sensor (pressure indicator sensor). Turn on the ignition. If the arrow returns to the beginning of the scale, then the sensor is faulty (or return it to the seller).

If you have a multimeter, you can check the sensor immediately in the store. The resistance of a working sensor is 290-320 Ohm

the connection is not much different from the oil gauge

orange - power supply is +. You can take it from the power supply that goes to the tidy - it’s also orange in the block
green - to the coolant temperature sensor. We connect to the green wire from the sensor in the tidy block.
white - backlight. It's best to take it from the instrument lighting - the white wire is in the block
black and white - the ground (body) is also in the tidy block.

The performance of any engine in a car directly depends on the quality and quantity of oil, as well as its pressure, which is created using an oil pump. The oil pressure sensor controls the transmission of the status indicators of these parameters.

Not every VAZ 2106 owner knows where this or that element is located. The oil pressure sensor in this vehicle is located on the left side of the cylinder block, under the fourth spark plug. This element should not be confused with the temperature sensor, which can also be found in the cylinder block, but a little higher.

The sensor design includes the following elements:

A round metal barrel on which there is one terminal for connecting a wire.
Membrane switch with contact on the end surface.
Steel tee.
Bronze washers acting as seals.

The principle of operation of the barrel is based on determining the amount of pressure, the nut, if necessary, manages to fix its absence, and the tee plays the role of a connecting element screwed into the engine.

Check and replacement

During operation of a VAZ 2106 car, the oil pressure sensor may fail, and the main reason for this will be its wear. Basically, a breakdown is detected by viewing the sensor indicators on the dashboard, and an emergency light can also indicate possible malfunctions.

In any case, before making hasty conclusions, you should check its performance.

So, for example, if the emergency light suddenly lights up while the car is running, and the arrow does not deviate, then it is recommended to check the serviceability of the pressure meter in the sensor. In order to carry out the check, you will need to use an open-end wrench and a pressure gauge.

A flexible pipe with a threaded tip is additionally screwed to the pressure gauge.
The check sequence is as follows:

The car engine turns off and cools down to a temperature not exceeding 60 0 C. This is necessary in order to avoid getting burned during work.
The next step is to disconnect the wires attached to the sensor. They can be unscrewed with a key together with the tee. It should be taken into account that during disassembly of the sensor, oil may spill out of the unit.

After this, the threaded part of the pipe is screwed into the vacated hole and tightened. Then the engine is started and the pressure gauge readings are monitored. The connection diagram is shown in the figure.

If, as a result of measuring pressure, the sensor produces results that differ from the standard ones - “7 Bar”, then we can conclude that there is a malfunction in the sensor and the need to replace it.
If the light signal on the dashboard lights up and immediately goes off completely, then the cause of the breakdown may be:

failure of light bulbs;
broken wires;
wear of the small hexagon-shaped sensor.

The first two options can be checked using a multimeter or a special tester, which will demonstrate the difference between the required indicators and the standard characteristics. In order to check the performance of the small sensor, you will need to see how the light bulb reacts to changes. This is done by turning on the ignition and removing the terminal from the wires.

The element is replaced by unscrewing any of the sensors - large or small with a wrench. In this case, it is important to pay attention to the number of sealing washers, since the new part may not contain such components. It is worth noting that both parts cannot be repaired, they can only be replaced.

What to do if the sensor lights up

If the oil pressure sensor warning light comes on, you must first check the oil level. The fact is that its deficiency can reduce the pressure in the oil system, which will negatively affect the performance of the engine. This is what the oil pressure sensor records.

At the same time, you should not delay adding oil, since any further breakdown of the system can lead to serious repair costs.
As a result, it must be said that the operation of the VAZ-2106 requires a responsible attitude, regular inspection of the performance of all systems and elements, among which the oil pressure sensor plays an important role.

Replacement and repair

It is easy to determine where the oil pressure sensor is located from the descriptions given above. There are other meters located in this sector, so care should be taken when performing work to replace or repair the sensor (it is possible to mistakenly remove the coolant temperature sensor).

This type of control element is inexpensive, so it is irrational to waste time trying to fix the problem yourself. Moreover, after self-repair, the correctness of the performance of such a device will remain a big question. If there is a suspicion that the oil pressure sensor is faulty, it should be replaced.
