Oil pressure sensor Kalina: where is the sensor located, how to remove, replacing the sensor

Location

Where the oil pressure sensor is located depends on the number of cylinders. On 4-cylinder engines, the device is located on one side of the engine. This is a small plastic electrical connection that is secured to the motor with a screw. 6 cylinder engines have a device under the spark plug wires attached to one side of the valve cover.

What does a burning oil pressure light indicate?

If the DDM indicator light on the instrument panel is constantly on, this indicates that the Lada Kalina oil pressure sensor is broken or the circuit is broken.

If after diagnostics it turns out that the device is faulty, it must be replaced (the author of the video is Alexander Skripchenko).

It is recommended to unscrew the old device before purchasing and take it with you so as not to make a mistake when choosing a new one. To replace it, it is better to purchase an original or a high-quality analogue. You should not buy a cheap product trying to save money on it, since a low-quality product will quickly become unusable and will have to be replaced again. If the DDM pad is in poor condition, it is worth replacing it too.

Replacement instructions

To carry out the work, you need to prepare a key for “21”.

The replacement procedure consists of the following steps:

First you need to open the hood and remove the protective plastic cover from the power unit.
Having found the sensor on the cylinder head, you need to disconnect the power terminal from it by pressing the latches.
If necessary, check the power supply.
Next, using the key set to “21”, unscrew the old device. We check it for serviceability.
If the old device is faulty, screw a new sensor in its place.
We connect the terminal with the power wire to the device, and return the decorative motor cover to its place.
Let's start the engine. The light on the instrument panel should go out.

If everything works, the DDM replacement ends here.

Thus, even a novice driver can check and replace the Kalina oil pressure sensor, which will make it possible to save time and money on visiting a service station.

Exploitation

The oil pressure sensor on the viburnum is part of a system that monitors the pressure near the engine pump and filter. For this purpose, the engine block has a socket with a threaded connection through which the sensor is fixed. Electricity meters use a device in the motor block to create a variable resistance that will influence the amount of current through the metering circuit and sensor.

Pressure meters require a power source. The electrical diagram shows that power flows through the meter and back to ground through the sensor. The meter readings as a whole will depend on the resistance of the sensor, which, in turn, is determined by the pressure.

Methods for checking the oil pressure sensor

The cost of an oil pressure sensor is extremely low, so many car owners recommend checking the original meter by installing a new oil pressure sensor in its place. After this, the power unit starts. If the sensor readings begin to correspond to reality, this means that the original meter has failed.

You can check using a multimeter. To do this, check the presence of voltage at the terminal connected to the meter. In the absence of power, the breakdown should be looked for in other elements, and not in the DDM.

The sensor can be checked using a pressure gauge. It screws into the DDM seat. When the engine is running, the pressure is monitored. If it is below 0.65 kgf/cm 2, then the sensor signal lamp should be on, otherwise the DDM is faulty.

If the low oil pressure indicator comes on while driving, the method below is an indirect way to check.

Unscrew the sensor from its seat.
Crank the starter without allowing the engine to start.
Check the DDM seat. If oil leaks from the hole, then the pressure should be normal and the indicator lights up indicates a failure of the DDM.

The following check of the oil pressure control sensor is more accurate:

Cut a small piece of hose.
Connect the pump to the hose on one side.
Connect the other side of the tube to the sensor.
Check the sensor resistance using a multimeter or ohmmeter. It should be minimal.
Start pumping air.
When the pressure reaches 0.65 kgf/cm2, it is necessary to measure the resistance again. The measuring device should show a gap.

Malfunctions and ways to eliminate them

The indicator can be activated when there is no pressure required to inject oil into the cylinders. Without the lubrication provided by oil, the cylinders may be damaged, requiring a new engine. The warning light may come on for a variety of reasons. First you need to determine whether this is a problem with the meter or something else.

Low pressure

Low pressure is the main reason the dashboard light comes on. The device determines whether oil is supplied in such quantity that it reaches all parts of the engine. If the pressure is insufficient, the friction of the parts rubbing against each other will cause heat and abrasion, damaging the engine. In this case, the device is not necessarily damaged; you should look for the cause of the low oil pressure.

Low level

Low oil level is not a common cause of sensor failure. With a small amount of lubrication, it is possible to circulate oil through the engine at sufficient pressure to activate the sensor. The reasons why the level is low are leaks in the distribution system, improper replacement of the drain plug or oil filter, and debris.

Faulty device

From time to time the unit may become clogged with contaminants, especially if the engine is not properly maintained. A clogged meter gives false readings, causing the warning light to come on.

Self-replacement

Replacing a faulty oil pressure sensor yourself is quite simple, following the step-by-step instructions:

To work, you need to prepare a car key for 21.
First of all, carefully remove the protective cover from the engine.
Next, you should pay attention to the reverse side of the engine, since the sensor is screwed into the cylinder head “socket” located on the right.
By pressing the latches, the holding pads must be disconnected from the pad.
Unscrew the sensor from the “socket” using a key.
A new sensor is installed in place of the old, failed one. Before installation, carefully wipe the surface of the “nest” with a clean cloth.
At the last stage, check the reliability of all installed components, fix the protective cover and check whether the problem has been corrected.

If after starting the engine the indicator goes out after a few seconds, this fact will confirm that the light came on precisely because of a malfunction of the oil pressure sensor.

As you can understand, the process of replacing the DDM is quite simple and understandable, so any Lada Kalina car owner can handle such work. If difficulties arise during the replacement process, you should watch the video instructions prepared by professionals at any time.

How to check the oil pressure on Lada Kalina?

It is no secret that the engine is the main component of a car, for the normal functioning of which a number of conditions must be met. One of them is maintaining optimal engine oil pressure. Reducing this parameter can lead to a number of problems - increased wear on the engine, a decrease in its power, disruption of the functioning of some components, and so on. But more about everything.

Functions of motor oil

Let's remember what tasks are assigned to motor oil. There are several of them:

Reducing friction between the main elements of the engine, as well as increasing their service life.
Formation of the required pressure level in all systems and components equipped with a hydraulic drive.
Effective heat removal from the piston system, bearings and other rubbing elements of the system.
Reliable protection of all engine components from corrosion.
Prevention of various deposits and the appearance of soot on the walls of the motor.
Protection of the engine from the action of acids that may form during combustion of the air-fuel mixture.
Elimination of any form of sediment in the main components (oil pipeline or engine crankcase).

Main reasons for lack of oil pressure

Before checking the oil pressure in the system, you must clearly understand the reasons for this phenomenon. There are several of them:

Reduced oil level in the power unit. To avoid this problem, you should check the oil level from time to time under the following basic conditions - the engine should be stopped and cool. If the level drops, it is necessary to top up using oil of the same type, brand and viscosity. After this, check the pressure again.
Increased oil filter resistance. Often, novice car enthusiasts make a mistake in choosing this unit and install a filter of the wrong type (intended for a different model). In such a situation, the throughput of the newly installed filter may not correspond to normal engine operating parameters.
Oil pump failure. A malfunction of this unit is a very common pressure issue. Its malfunction can be caused by simple contamination and the presence of significant deposits on the internal filter elements. To fix this problem, you may need to replace the pump. As a rule, car enthusiasts do this work with their own hands, without going to a service station.
Increasing the gaps between the main elements of the power unit. The main reason is wear and tear. There are times when, even if all the problems listed above are eliminated, the pressure in the system remains at an extremely low level. In such a situation, disassembling the engine and checking the main clearances can help out. In particular, special attention must be paid to the distances between the bearings and the connecting rod journals.
Coolant or fuel getting into the engine oil. A similar problem can occur for a number of reasons - burnout of the cylinder head gasket, wear of the rings, failure of one of the cylinders, and so on. In the event of such a malfunction, it is no longer possible to do without changing the oil and repairing the engine.
The oil pressure sensor is broken. If after diagnostics (we will look at its essence below) it turns out that the oil pressure in the systems is normal, but the sensor still gives a signal to the contrary, then the only way out is to replace the sensor.
The wiring has failed. In domestic cars, this reason is one of the most common. The emergency oil pressure light may light up due to damage to the switching conductors.

Old spark plugs and high voltage wires

If the engine light comes on, you need to check the spark plugs. They perform an important function; they participate in the ignition of fuel in the engine. If the spark plugs are faulty, then the spark is not supplied to the gasoline mixture. If there is no spark, the car may not start or the engine may not operate properly. Incorrect operation of the spark plugs leads to small tremors.

Car service specialists recommend replacing spark plugs after 25-30 thousand kilometers, especially if the car is old. However, the service life of spark plugs is directly influenced by the quality of the fuel and driving style. Faulty spark plugs are usually very noticeable.

The car starts with difficulty.
Fuel consumption increases.
The catalyst fails.

This is why spark plugs need to be changed regularly. Their cost for Kalina is low, and you can do the work yourself. Timely replacement of spark plugs will significantly increase the life of the car engine. In order to replace the spark plugs, you will need a spark plug wrench. The condition of high-voltage wires must be monitored.

They often fail, which renders the ignition unusable. Electrical leaks appear, which affects the strength of the spark. Serviceable spark plugs will extend the life of many vehicle systems and improve engine performance. Why might the light still be on? In most cases, a lit icon on the panel means that there are problems with a particular system that need to be fixed. Sometimes nothing bad happens, which means everything is fine. When the engine starts, the light comes on and then goes off. But if it continues to burn, this means that you need to look for the cause.

If the light flashes while you are driving, you should stop the car and check the engine oil level. Sometimes the oil filter fails. In some cases, it becomes necessary to change the engine oil. It will be useful to inspect the power unit for damage. If the light continues to blink, you need to go to a service center and have it diagnosed.

The quality of operation of many systems is controlled by the on-board computer. If any of them starts to fail, this causes the light to start blinking. In order to know exactly the cause, it is best to conduct a diagnosis. In most cases, a situation in which the check light is on can be avoided through regular technical inspection.
