Why does the oil pressure light come on on a VAZ 2107?

Reasons for the indicator to light up

It should be noted that the oil pressure light may come on intermittently in some situations without presenting any danger to engine operation. Such situations include:

If the car makes a sharp turn, as a result, not only the oil indicator, but also the fuel indicator may light up for a few seconds.
When starting the engine in winter.
After prolonged parking on uneven surfaces, when the lubricant flows into other engine compartments.

If the light comes on while driving or at idle, and does not go out after a while, then appropriate measures should be taken. The oil pressure indicator indicates the occurrence of failures and malfunctions. Such problems occur not only in the engine, but also in the electronic part. Some of the main reasons why this indicator lights up include:

Reduced oil level in the system. This is precisely the fact that, when it occurs, the indicator must necessarily work, warning of the danger of further operation of the VAZ-2107 car.
If the oil filter is worn excessively.
There is a malfunction of the sensor itself or a short circuit in the wiring.
Excessive wear of the crankshaft bearings.
Oil pump malfunction.

Level needs to be checked

In certain cases, it is necessary to stop and determine the presence of oil in the engine using a dipstick. If the level is normal, then you should get to the nearest station or home, and then determine the reason for the light coming on. If there is no oil, then continuing to move under your own power is strictly prohibited, because this may cause the motor to jam.

If the pressure indicator lights up, you should make an emergency stop and turn off the engine. After this, a number of steps should be taken to determine the cause of such consequences.

Checking the lubricant level

After stopping, you need to open the hood and remove the dipstick. The measuring scale of the dipstick should be wiped, then reinsert it into the hole, and then remove it and make sure there is a sufficient level of lubricant. If the dipstick shows a minimum fluid level, then you should top it up, but then try to find out the reasons for the decrease in level. Often the reason for a drop in oil level is its leakage through the seals, which need to be changed periodically.

After the oil is added to the engine, the indicator will not light up, which indicates that the cause has been correctly eliminated. Low oil pressure in the engine can also be determined using a special dial-type indicator, which displays information for the driver about the state of oil pressure. However, on VAZ 2107 cars such indicators are not installed from the factory, although some motorists install them themselves.

Oil filter malfunction

If the lubricant level is in order, then the cause of such consequences may be a faulty filter. If you recently changed the oil and filter, and after some time the light comes on, then there is a high probability that you have received a defective filter. Under such circumstances, you will need to replace not only the filter, but also the lubricant in the system. Such cases, although rare, are all appropriate.

Checking the health of the sensor

The malfunction may consist of a breakdown of the sensor itself or a short circuit in the supply wiring. To check the health of the sensor, there are two ways:

Measure the pressure by screwing an adapter with a pressure gauge into the sensor seat.
Measure the resistance using a multimeter and a pump with a pressure gauge.

In the first case, the pressure in the system must be at least 0.35 kgf/cm2. The value on the pressure gauge is not lower than the specified one, indicating that the system is working properly and the sensor is faulty. In the second case, the test involves connecting the multimeter probes to the sensor terminals. In this case, the device should show zero resistance. Now you need to pump using the pump, as a result of which the multimeter readings should change and it will show infinity. In order to check the integrity of the wiring suitable for the sensor, you should test it using a multimeter. Replacing the sensor is not particularly difficult, so even a beginner can cope with this task.

Checking the quality of the lubricant

If all of the above methods have been tried, but the icon continues to light, then you should check the quality of the oil. To do this, you need to inspect the dipstick, with which you can easily determine the presence of signs of antifreeze or gasoline in the lubricant. To do this, you need to dip the dipstick in water and see if streaks appear on the surface, then the reason is that foreign liquid has entered the motor.

In such a situation, a complete flush of the engine, as well as major repairs, cannot be avoided. It is necessary to eliminate the cause of gasoline or antifreeze getting into the engine compartment.

From the above, it should be noted that in order to avoid unpleasant situations, when the oil pressure light comes on, you should immediately stop and find the cause.

Why does the oil pressure light come on in a VAZ classic?

The first step is to distinguish cases when an icon in the form of an oil can is suddenly displayed. It is completely safe for the icon to light up for just a few moments in the following cases:

when there is a strong roll of the car on a sharp turn;
when starting in winter;
after a long period of parking on uneven ground.

As a rule, in such situations, oil flows from one part of the engine to another, which is why the oil pressure sensor is triggered. However, after some time, the working fluid is evenly distributed, and the signal about a drop in pressure in the system stops. The situation is similar when starting the engine unit in the cold season: at low temperatures, the working fluid thickens, accordingly, it is necessary to warm up the engine properly in order to create the necessary pressure in the system.

In all other cases, the appearance of an oil can on the instrument panel indicates the presence of failures or malfunctions. So for what reasons can the oil pressure light come on in classic VAZ models?

First of all, due to a lack of oil in the engine.
Due to an exhausted oil filter.
The oil pressure sensor or its wiring is to blame.
Wear of the liner on the crankshaft.
The oil pump has failed.

Any of these reasons can affect the oil pressure level in the engine unit. Therefore, the car owner will first have to find the source of the problem and only then begin troubleshooting.

The oil level control device is located separately

Oil pressure light is on at idle

The oil pressure lamp is on/off

Unread message L1nch » Sat Oct 09, 2010 11:36:45
Yesterday I bought my first car - VAZ 2107, 2001, carburetor. The first and so far only problem has arisen - the oil pressure lamp lights up, goes out and comes on again under the following conditions: 1. The car is not warmed up, the lamp does not light up. 2. The car warmed up, the lamp came on at idle. 3. Added gas, the light went out, removed the gas, the speed dropped, the light came on again. 4. The presence of oil in the pan is maximum. The car has not been used for the last six months. The former owner of the car cannot say anything about this. On Monday I'm going to go wash the engine, change the filters and fill up with new oil. Maybe it will help. After searching on the Internet, the problems may be as follows: 1. Filter 2. Oil pump 3. Spark plugs 4. Electrics

Who had similar problems, dear forum users? Who has encountered this and which option is most likely? I wouldn’t want to find out after changing the oil and flushing the engine that the problem is in the pump.

Thanks in advance to those who responded. Sincerely.

First or second. Or maybe the sensor itself...
