Why the oil pressure lamp of the VAZ 2110 is burning. Checking the health and procedure for replacing the oil pressure sensor "Tens"

There are many different indicators on the car instrument panel. From time to time, motorists face lambda-probe lightning lamps, low fuel levels, the inscription "Check Engine" and many other "fools." However, what to do if the VAZ 2110 is lit on the panel board and its indicators are further in our article.

Purpose

This device is intended to determine the level of oil pressure (in our case low) and the output of the necessary information on due to a timely alert can be eliminated in time and avoid expensive since with an insufficient number of this fluid, the piston works "dry".

But not only the insufficient oil level can notify this device. Also, the ignition of the red light can trigger a malfunction in the pump itself, even if there is a sufficient amount of lubricating fluid in the engine.

Characteristic

What is characteristic of the design of such a detail, as an oil pressure sensor? VAZ 2110, like many other cars domestic production, equipped with the most primitive sensors in design. They are a float that moves along a special guide tube. There is a magnet inside the float. The tube contains the Geron (magneto-controlled contact). The latter is triggered when a magnet is approaching it. At this time, the red light lights up on the instrument panel, signaling about the insufficient oil level in the DVS lubrication system.

What if the indicator caught fire

Some motorists fall into panic when a similar indicator is detected, others ignore this signal And continue to move. But how can you actually behave if in the system low level liquid content?

If the oil pressure is lit on the instrument panel, the VAZ 2110 must be stopped and drowning its motor, since the engine can really work "on dry" when the red indicator appears.

What is the most interesting, on cars of domestic production, the sensor has a "lie" property, that is, it lights up in the absence of objective reasons. In this case, it needs to be distributed. How to make sure the performance of such a detail as a pressure sensor? VAZ 2110 and its subsequent models are diagnosed as follows.

First of all, you should check the chain from the sensor to the pressure control lamp. How it's done? To do this, it is enough to watch the wire from the sensor on the "mass". If the pressure lamp went out, then the chain is in good condition.

Sometimes it happens that the sensor itself is "enveloped" oil liquid. In this case, it is subject to replacement. If the lamp continues to burn, most likely, the system stopped working either a filter.

Depending on the results obtained, it is necessary to replace the nanos together with the filter or simply add lubricating fluid to required level. And remember - if there is no oil pressure on the VAZ 2110, it negatively affects the work as a result of which the encoding of parts of KSM and overhaul is inevitable.

ON REPAIR

If you think that this device can be repaired and reinstall, you are deeply mistaken. Even with a large experience of car service it is impossible to restore the oil pressure sensor. VAZ 2110 is no exception. First, it may take a lot of time and effort on its repair. Secondly, even after that, the item will not function normally. Exit only one is to acquire a new oil pressure sensor.

VAZ 2110 - the car is very cheap in service, so the cost of a similar spare part is small - only 60-100 rubles. Well, replacement this device Does not take you and five minutes.

Where is the oil pressure sensor from "dozens"

Depending on which engine was installed on "Lada", the sensor can be located in two places. On eight-smelted "dozens" DDM is on the right side of the engine. It is located on the top left part of the camshaft bearings on the upper left part of the camshaft bearings.

Replacing the sensor with their own hands

As we said earlier, installing a new part will not take you of much time. The replacement procedure itself is produced only in 3 stages:

First you need to disconnect the wire from the sensor.
With a key of 21 millimeter, free from fasteners.
Pull out the device together with the sealing ring.

Setting the part is made in reverse sequence. Motorists recommend mounting the sensor along with a new sealing ring. Analogy will be the cleaning of contacts when the electric plug is connected. If a dust seal is damaged on the device, it is recommended to replace it.

Burning control lamp in the form of a red maslinka on dashboard - This is a signal that the pressure in the lubrication system fell to a critical minimum. It is impossible to ignore it in any case, because without oil the engine VAZ 2110 or any other car will not live for a long time.

Principle of operation of the control lamp on the VAZ 2110

Control lamp emergency pressure Oils in VAZ 2110 cars are located in the lower left corner of the instrument panel. It is easy to identify by the characteristic icon in the form of a maslinka.

Control lamp of an emergency oil pressure is located in the lower left corner of the panel

The light runs in a pair with an emergency pressure sensor, which is installed in the head of the cylinder block and is connected to the oil mainstream. These two elements are combined into the simplest electrical circuit according to the type of check lamp, where the sensor performs the function of the switch. The design of the sensor is also very simple. It consists of a housing with a fitting and membrane with a contact connected to on-board network cars.

Construction and scheme for connecting an emergency pressure sensor

When the engine is turned off, there is no pressure in the lubrication system, and the membrane is in a free position. The contact at the same time is closed on the mass of the sensor. When we turn on the ignition, but do not run the motor, everything remains the same, only the power is supplied to the contact. Since the chain is closed, the control lamp is burning. As soon as we ran the engine, the pressure in the system begins to rise and affect the sensor membrane, moving it away. The contacts are blocked, and the lamp goes out. But this happens only when everything works fine.

Why burning emergency pressure lamp burns

If you notice that the lamp is constantly, or is turned on periodically during operation power aggregate, hurry to diagnose and find possible malfunction. Until her elimination, the car is better not to continue. The causes of permanent or periodic burning of the control lamp can be:

insufficient lubrication level in the engine, as well as poor quality (spent its resource or not appropriate viscosity class) oil;
breaking or short circuit in emergency pressure sensor circuit;
sensor malfunction;
clogging oil filter;
clogging of the mesh oil filter;
fault oil pump or Him reduction valve;
insertion failure crankshaft.

We will analyze each of these problems in more detail.

Level and quality of oil

The first thing when sunbathing a control lamp should check the lubrication level in the engine. To do this, we use a special probe, which is provided in both octal flap and sixteen-flaped power units "Tens". Measurements should be made when the motor has cooled. If their result shows that the oil level is lower than the minimum - the result of it and check the operation of the sensor with the lamp.

Pay attention to the oil consistency. Than more car From the moment of its replacement, the alone, and the oil pump, calculated on a certain viscosity, of course, will not be able to create the necessary pressure. In such cases, the lamp, usually, lights up when the engine is heated to the operating temperature.

If the oil level is lower than the minimum, it must be addressed

Similar symptoms can also be observed when using oils, the viscosity class is lower than the engine manufacturer. If you are not sure about the quality of lubrication, it is better to replace it.

A few words about the location of the sensor

Before proceeding with the description of the sensor check algorithm, let's figure out where it is located. In eight-flaped VAZ 2110 engines, the sensor is located on the back side of the engine at the right upper part of the cylinder head (if you look from the car's interior). You will not confuse it with anything, because there are no other devices there.

The sensor is located on the back of the engine in the upper right side of the GBC

In sixteenthlylated power units "Tens", the sensor is located on the left side of the engine near the filler neck. Faster to navigate you will help the power wire that goes to the device.

Emergency pressure sensor oil is located next to the plug-in neck

Verification of emergency pressure sensor circuit

In the case of a periodic switching on the control lamp, check the sensor power wire. It often happens that his breakdown or closure on the mass is the cause of the flicker of the "maslinka", especially during the movement. The verification procedure is as follows:

A visual inspection of the wire and the restoration of its damaged plot will help solve the closure problem.

Sensor check

Motors of cars 2110, regardless of their modification, are equipped with an emergency pressure sensor type mm 120, manufactured under the catalog number 6022.3829.

Emergency Pressure Sensor MM 120 Oil Pressure

Sensor characteristics mm 120:

rated voltage - 12 V;
mass - 28 g;
thread - M14x1.5;
pressure pressure - 0.4 ± 0.2 kgf / cm 2;
analogs - mm 120d, mm 120dm.

Sensors of emergency oil pressure on "dozens", as in principle, on other vases - devices are very capricious, and failure very often. Check them at home easy.

Tools and Tools for Check:

tire compressor or pump with pressure gauge;
cut of the hose internal diameter 10-12 mm 20-30 cm long;
2 clamps;
crosshead screwdriver;
key to 21 or 22;
car tester or warning lamp with power element;
dry rag.

The procedure for checking the sensor is as follows:

You can, of course, do not waste your time check, but just buy and install a new sensor. Especially since it is about 70 rubles.

Oil filter

The clogging and wear of the oil filter invariably lead to a decrease in oil pressure in the system. In a working, correctly selected and installed filter after stopping the engine there is always a certain part of the lubricant. This is provided for by the design of the device. If the filter is worn out, or does not correspond to the modification of the engine, the oil will flush from it into the crankcase, causing the "starvation" effect in the engine.

When clogged the filter element decreases its bandwidth. The pump at the same time works in normal mode, however, the amount of oil entering the system is reduced. Naturally, this leads to a drop in pressure. If you are unsure in accordance installed filter Engine parameters, or a car with him passed more than 7 thousand km - replace it. The new filtering node on the VAZ 2110 will cost you about 200 rubles.

Important: It is advisable to replace the filter simultaneously with the replacement of lubrication. When installing a new filter, be sure to fill its body with fresh oil. This will prevent the appearance aerial traffic In the system and keeps the engine from oil "starvation".

When replacing the oil filter, be sure to fill its housing with fresh oil

Pressure check

Further search possible causesThrough which the control lamp lights up, requires partial or complete disassembly of the engine. To make sure that the problem has fallen really deeply, it is necessary to measure the oil pressure in the system. You can do it yourself, if you have a special pressure gauge. And if not - you can buy it. It costs about 300 rubles. In addition to the pressure gauge, you will also need a key to 21 or 22 and dry rag.

Procedure:

Mesh oil worker

The oil worker is designed to take oil from the pallet of the crankcase and feed it to the pump. To make wear products with lubricant to the system, the device is equipped with a mesh filter. The clogging of this filter prevents oil flow in full.

In order to get to the grid of the oil worker, they will have to drain the oil and remove the pallet of the crankcase. The device is attached to the Carter and the oil pump with three bolts. Having unscrewed them, the oil worker can be dismantled. Disassemble the filter will not work, as it has a one-piece design, but you can still clean. For these purposes, the White spirit is used, solvent, various domestic products for cleaning sewer pipes.

When clogged with an oil truck grid, the pressure in the system is reduced

Oil pump

Oil pump is the main element of the system. It he creates pressure in it, nervous lubricant in the highway. The main faults of this node include the wear of its details, as well as the "sticking" of the reduction valve, which happens much more often. To establish the exact reason for which the pump does not cope with its responsibilities, you can only withdraw it and disassemble. Dismantling of the oil pump involves removing the pallet pallet, the right wheel of the car and the crankshaft pulley.

In most cases, the problem is solved by replacing the device. Buying a new oil pump will cost approximately 1000 rubles.

Crankshaft liners

The pressure in the system may fall because of the strong wear of the indigenous or connecting rod inserts crankshaft. This phenomenon occurs on the engines, which passed without overhaul more than 200 thousand km. Detect such a malfunction can only after the engine disassembly.

Worn liners skip more oil, which affects the pressure in the system

Video: Causes and consequences of pressure drop in the lubricant system

Diagnostics of the lubrication system - the process is quite complex and time consuming. But without it, it is not necessary to do without it, especially since the car itself gives you a disaster signal. It is better to lose a day in search of a minor malfunction and try to eliminate it than then carry out overhaul engine.

Some car enthusiasts during the operation of the "dozens" are faced with the situation when the engine has previously heard for further operation, idling The lamp-transparency begins to flash and light up, indicating insufficient oil pressure in the engine crankcase. At first she starts to flash periodically, and then her burning becomes constant.

Causes of oil pressure sensor malfunction

The reasons, of course, can be plentiful. But it often happens that it is enough to replace the oil pressure sensor of the VAZ 2110, and the problem can be solved overnight.

And in practice, many motorists are as follows: if the oil sensor caught fire in the VAZ 2110, the driver starts to take a whole range of inspections, among which the following:

control over the oil level in the engine crankcase;
conduct measurements of pressure parameters in the system of lubrication of the unit;
replacement of oil and oil filter;
flushing of the lubricant system of the power plant.

In this case, the result remains unchanged - the lamp continues to burn.

IMPORTANT: If when initiating the ignition system, the oil sensor lamp VAZ 2110 goes out, then it is necessary additionally necessary to all the above measures to purchase in a specialized automotive store new light bulb And make it a replacement.

All these activities are important, but their holding can be postponed for later, and in the first place it is necessary to test the oil level sensor 2110, especially since it is required to spend a short time. When replacing this detail, the problem with the fact that the oil sensor is on, will be solved and the fault will be eliminated.

Summing up, we conclude: When sunbathing or swelling lamp-transparency, check the oil pressure sensor, which may be faulty.

Conducting the test of the VAZ 2110 oil sensor and its replacement

Operating procedure:

We check the plot of the electrical circuit from the desired sensor to the lamp signal. To do this, contact the wires of the "dozens" oil sensor closer on the motor block and check with an assistant if the pressure lamp caught fire on the front panel of the car. If the source of the sunbathing goes out, the wiring is in working condition.
Remove the oil sensor of the VAZ 2110 oil and conduct its visual inspection. If its surface is dry and does not carry damage traces, then it is most likely in working condition and the defect should be sought elsewhere. The same surface of such a product as an oil pressure sensor contains lubrication traces, it is necessary to replace it new detail. Moreover, the price of this product is insignificant and ranges from 50 to 100 rubles.

When carrying out such a type of repair, as replacing the oil sensor VAZ 2110, it is necessary to know its location in the power compartment of the car. For newcomers, first participating in such an operation, we inform that this product is located on the camshaft housing.

The procedure for replacing the sensor:

Remove the contact wire from the product.
We dismantle the item using a wrench on "21". In the production of dismantling, it is necessary to trace the product that together with it it was removed the ring of aluminum seal, which is also subject to replacement.
We take a new VAZ 2110 oil sensor, which is pre-acquired in a specialized car store, and together with the new aluminum ring, we set it to a regular place.
Before fixing the contact contact, it is necessary to test them, i.e. they must be cleaned and exempt him of the lacquer layer, and if they are subjected to oxidation, their stripping is required.
Examine the state of the anther product, which should not have traces of gusts and cuts. And only in this case you need to install it in place. If the freezer products is deformed or has a ribbon, not a solid surface, it must be replaced.

Sometimes it happens that, by conducting a change in the oil sensor VAZ 2110, oil also appears on the new product, i.e. Lubricants are formed. This happens because of the acquisition of either poor-quality products, or the purchased part is not a regular car for this brand. Some car enthusiasts complain about the defective products that are implemented in car outlets.

For considerable conviction and clarity to the creature of this problem, you can call for advice from specialists in the service authority or station maintenance cars.

The engines installed on the VAZ 2110 car are controlled by electronics and have numerous sensors, information from which is processed by the engine control unit. If there are any problems on the dashboard, Check Engine check light lights up. The presence of such a warning indicates serious engine problems, so it is necessary to deliver a car to the service as soon as possible and carry out the appropriate troubleshooting diagnostics. In this article, we will tell you why on 8 and 16-valve engines VAZ 2110 the check lights up.

Introduction Candles

If the engine chase caught fire on the dashboard of your VAZ 2110, first of all it is necessary to pay attention to the condition of the candles and high-voltage wires. Over time, the ignition candle clearance changes, as a result, there is a spark in the cylinders, and the corresponding sensors determine the problem. That is why, as soon as such alarm is caught fire, it is necessary to check the candles for the presence of sparks. Car owner should also be examined by the state of high-voltage wires that may have mechanical damageWhat leads to the wrong operation of the power unit in the VAZ 2110. Remember that the candles must be changed regularly, which will avoid similar problems with the car engine.

Throttle problems

Problems can deliver the sensor located on the throttle. Unfortunately, independently perform diagnostics in this case is not possible. Car must be towed to the service where specialists consider mistakes with special equipment throttle valve Or they will determine other problems with the engine, which can lead to a check engine light bulb.

Mass flow sensor breakdown

Light alarm faulty Engine May also have problems with air flow meter. Such a sensor (DMRV) often fails or starts to work incorrectly, which leads to malfunctions in the motor. Indirectly identify problems with the mass flow sensor in the VAZ 2110 engine, it is possible by significantly increasing fuel consumption. Note that the engine with such damage is not recommended, so if Check Engine caught fire and the fuel consumption increased, it is best to drive up to the service and spend high-quality computer diagnostic. The cost of spare parts I. repair work In this case, it is not too high, which will fully restore the performance of your car.

Refueling by poor-quality fuel

Check Engine light bulb can light up immediately after refueling with poor quality fuel. Such a dirty I. embossed fuelBy entering the engine, invariably causes an increased detonation and incorrect operation of the injection system, and eventually the motor control unit receives errors from the built-in sensors and the check on the dashboard lights up. In the event that such alarm tagged immediately or soon after refueling, with a large share of probability, it is substantial fuel. It is not recommended to operate the car in this case. It is necessary to call the tow truck, take the car to the service where experts are comprehensively digging the car and perform cleaning fuel system. Otherwise, damage to the injector is possible, which will lead to expensive engine repair.

Insufficient oil pressure in the system

Check Engine may light up if there are problems in the lubrication system. For example, with insufficient oil pressure or in cases of breakdowns of an oil pump, which does not pump the lubricant, the temperature of the engine invariably increases and the corresponding warning on the dashboard lights up. At the same time, the lamp of insufficient oil pressure can light up.

Problems in the work of the ignition coils

High-voltage ignition coils and problems in these nodes can also lead to the appearance of an appropriate warning on the dashboard. Indirectly identify such problems in the characteristic trembling car on idling. The car owner can check if there is a current on the coil and the contacts of high-voltage wires are not weakened. If there are problems with coils, they are best replaced by a set. On the VAZ 2110 engine there are four high-voltage coils, the cost of which are at an affordable level, and every car owner will cope with such a replacement.

Lambda Probe breakdowns

On the 16-valve modifications of the VAZ 2110 engine, a lambda probe is established, which is responsible for the analysis of exhaust gases. Over time, a layer of spent oil appears on the surface of such a lambda-probe, which leads to problems with the accuracy of the sensor indicators. As a result, the Check Engine alarm lights up, and the car must be left to the service. It is impossible to determine the problem with the lambda probe. Only when the car is diagnosed on special equipment, you can define the appropriate error codes on the basis of which problems with the lambda probe will be detected. This element is not subject to repair and when breakdowns simply changes to a new one.

Furious catalyst

Catalyst problems can also lead to the appearance of Check Engine. It is possible to indirectly identify such problems due to the appearance of uncharacteristic idle sound, the motor at the same time begins to smoke hard. It is necessary to check the catalyst for a hundred and when identifying problems with this node, it must be replaced with a new one or cut. It is not recommended to use the machine with a damaged catalyst, since this can lead to various kinds of serious breakdowns, including the need to perform overhaul Power unit.

Check

1. First check the chain coming from the detail to control lamp. This is done like this:

take the sensor wire;
lean it to the engine;
ask someone to see if the lamp is burning.

If you went out, then everything is in order with the wires. Therefore, go further.

2. Remove DDM. If it is dry, it means, a worker, and the reason that the lamp lights up not in it. Now you can do all the above-mentioned things: check the oil pressure, look at its level and quality. And if necessary, change it along with the oil filter.

And if the oil pressure sensor of VAZ 2110 was oil, then it's all about it. You can correct the situation in one way: buy a new DDM.

Repair it - no sense. He will still not work correctly. It is easier to buy, and it is inexpensive - 50-100 rubles.

But here there is another question ...

Where is and how to change it?

The sensor is on the camshaft cover.

It needs to be changed in this order:

disconnect the wire from it;
unscrew it - the key to 21 will help you in this;
pull out the sensor - see so that a sealing aluminum ring together with it (it also needs to be changed);
put a new DDM.

Before connecting to it, the wire:

check the contacts - they must be clean (if not - clean);
look at the dust seal - it must be integer.

Wait a minute, please. There is still important information

It is possible that when the pressure sensor is replaced, oil will also leverage from the new. Then you buy another and put it. After some time, he can flow again. Why is this happening?

In most cases, this is due to faulty sensors. Even new they can be defective. The owners often complain that they have to change them two or three times, because they are defective.
