Priora car ignition coil, manufacturers and price

To go, you need to start! The ignition coil of a Priora car is not expensive. Its price for VAZ 2170 is from 2000+ rubles. On some machines this is a sore part that constantly breaks down. On a Priora with a 16-valve engine, there are about 4-5 analogues of this part.

Read the article to the end and find out how to check its performance and which one is better. Starting the engine of a Lada Priora car is a difficult procedure, which involves several parts and assemblies at once. At the same time, the standby engine start is carried out very quickly. At this time, several small subprocesses take place, and one of them is the creation of the first spark to ignite the fuel-air mixture.

To create a spark, it is not possible to place an open fire under the hood. The injection engine has become more “advanced” compared to its carburetor predecessor - it uses ignition coils, one installed with each cylinder.

An incident may occur, causing the engine to start “unevenly”. You will have to immediately look for how to check the elements of the ignition system. If it turns out that the problem is in these small parts, do not rush to despair, because in stores there is a good standard ignition coil for Priora 16 valves, the price of which is comparable to analogues. The wires to the ignition coils are an equally important component, which if it doesn’t work, you won’t go anywhere.

Basic faults

A normal Priora part should last from 50 to 100 thousand kilometers, depending on how often you start the engine. If an element of the Priora ignition system malfunctions, the following symptoms will occur:

When accelerating, the car will jerk (as if the box is kicking in a car with an automatic transmission), or when driving in first or second gear.
The integrity of the winding is broken. It is worth paying attention to the tip of the ignition coil of the Priora car.
The motor "troits". This manifests itself in vibration and excess noise that appears under the hood, while traction decreases.

The procedure for checking the short circuit

So, there are signs of a malfunction, you should check it.

First of all, the coil must be dismantled. For this you will need:

prepare a ten-point socket wrench;
disconnect the terminals on the battery;
open the protective casing covering the motor;
press the locking device out of the plastic, disconnect the wiring from the coil terminal;
remove the fastening bolt;
pull out the ignition coil.

An inspection is now underway. It should not show any cracks, melts or leaks on the caps and body parts. Only slight smokedness is allowed. Electrics can be checked in several ways. Having installed a working spark plug, we check the device for the presence of a “spark” on the car body. If there is no spark from the coil, then it is quite possible that the short circuit has lost its functionality. In such a situation, you should check the gap in the spark plugs. All work should be performed with rubberized gloves to completely prevent contact of the body or tool with the car body or engine. The fact is that the coil is capable of generating voltage in the range of 20 - 40 kV. Another option is to remove the coil and install it on a good cylinder on another car to perform a drive test. If the short circuit is faulty, it will immediately appear. The third method is instrumental.

The main reasons why the ignition coil breaks are considered to be high temperatures or overheating, which contribute to the formation of cracks. There is a high probability of short circuit failure due to the accumulation of moisture or the formation of corrosion, frequent switching on of the ignition without subsequent starting of the engine, prolonged overloads when an unsuccessful attempt to start the engine.

Design and principle of operation

So, starting the engine begins with turning the key in the ignition switch. At the same time, current must flow to the spark plugs, they give a spark to the fuel-air mixture, which is pumped up by the pump, the starter begins to rotate, causing the crankshaft to start moving. But the battery operates with low voltage electrical current.

Each coil is a small transformer. Two levels of winding are hidden under the housing of the element of the VAZ-2170 Priora ignition system. Its wires are low-voltage and high-voltage. The first ones receive current from the battery, the second ones transmit it to the spark plugs. When the current is converted, it is transferred to the spark plugs. The ECU “manages” this process, correctly distributing the force between the spark plugs.

As for how many ignition coils are in the Priora, there are 4 of them - one for each cylinder. Their work does not mix or overlap in any way. Each of them has “its own scope of work.”

Did the check bounce? or overworked?

Understood. When I get cold, it stops warming up. the check is not lit.

do diagnostics, it happens that there is no check and the error hangs in the computer

I'll connect tomorrow morning. I have an adapter! Thank you!

Priora 11th century I changed all the coils, all in winter.

a colleague of the Prior and he changed 3 coils since 2014, he was told in the service that this is a disease of the Prior, namely these motors with coils, and they said that if one coil is covered, it will be covered after a while... conclusion and people buy Priors after this?7

What nonsense, I have a 5-year-old Priora, all the coils are factory, the spark plugs need to be changed on time and the coils, if it had the old grin from the factory, then there is nothing to be surprised about

this is complete nonsense, this is a disease of these coils, not the priors, I had all of them relatives, and they drove 80 tons. The 124 engine was previously installed with Bosch from the factory and no one had any problems with it; people drove 200 tons without changing them. And they have already started installing some kind of bullshit on the Priora. Conclusion: when the coil burns out, just install the Bosch and that’s it! My Bosch has never burned out

Of course, I don’t know how it was on the Prior, but there was an Opel on which the coils were broken, they come assembled, are expensive, but they break just as often, and the reason is an increase in the spark gap of the spark plugs and the spark goes there much easier, i.e. to mass. conclusion: it is better to change spark plugs more often, because... They are cheaper than coils and make sure that they don’t consume oil. oil in the combustion chamber is the death of spark plugs

Manufacturers and prices of analogues - which ignition coils are better for the Priora

No one, not even AvtoVAZ, promises that the analogue will work as long as the standard model. There are a sufficient number of options on the market. It will take quite a long time to determine which is better. The following components are suitable for Priora 16cl:

SOATE (manufactured in Stary Oskol) (article 2112-3705010-12), price – 1,200 rubles.
MZATE-2 (article 59.3705), price - 1,000 rubles.
Baker Priora 2112-3705010-10 – 1100 rubles.

Performance check: how to check ignition coils on a Priora

Before you start replacing the ignition coils, you definitely need to check them and inspect them. Cracks, chips, and other damage to its body are unacceptable. If you see that the plastic is damaged, it means the part has overheated and cannot be used further.

The answer to the question of how to check an element of the 16-valve Priora ignition system is not limited to inspection. First you need to swap them and see if there are interruptions in the other cylinder. If there are interruptions, the problem is in the coil. There are several ways to use devices. To work you need:

Secure the car in place and turn off the engine.
Remove the negative from the battery.
Disconnect the part from the motor, and then connect a fully functional spark plug to it.
Turn off the fuel pump.
Use protective equipment against electric shock, this is a must!
Turn on the ignition and crank the starter. The spark plug should spark during normal operation.
Sometimes repair of the Priora ignition coil begins after receiving data from the ECU. The codes start with 0301 and end with 0304, indicating each cylinder accordingly. However, the problem is displayed in the coil-plug module, so the culprit will have to be found out separately.

Now we check the ignition system element on the Priora with a multimeter. For this and further work with components, models AZ-1 or MD-1 are suitable. For this:

Remove the part to be examined from under the hood.
Set the measurement switch to the “200 Ohm” position, connect the probes. The display should show “0” or values close to it.
Using probes, the external winding is checked. Pinout – 1.3. The display should show exactly 0.08 Ohm. The error is the number that the display showed during calibration; it must be subtracted. If nothing is shown, check that the probes are accurately touching the winding. If there is contact, but there is no result, the winding is broken and needs to be replaced.
Set the multimeter to 2 MΩ measurement limit to test the high voltage winding. Connect the black probe to the terminal of the second connector, and the red probe to the terminal of the coil. The indicator should be 342 kOhm - but only for a cold part. It should be cooled before testing. This also requires checking the exact contact with the probe.

Remember that the winding of this spare part does not change, but the tip can be easily changed. Most often, repairs are limited to routine replacement - in order to be completely sure of the tightness of the part.

conclusions

Thanks to this simple procedure, you can quickly check the performance of the ignition coils on a VAZ-2112 with your own hands, without resorting to the help of special diagnostic stations and specialists.

Elegant car

Lada Priora has everything you need for ease of use of the car:

sweeping body lines;
excellent design;
a large set of options;
high cross-country ability;
attractive price.

The ignition coil is the most important component of the car, and its failure will cause a huge amount of trouble. Mostly they will be associated with stopping and disturbances in the operation of the engine. The ignition coil is directly related to a unit called the “distributor”.

This is a distributor that receives low-voltage power from the vehicle's on-board network. The process of converting low-voltage into high-voltage power occurs. From the contacts of the distributor, the voltage is sent via a “slider” through a high-voltage wire to the spark plugs. The screwed-in spark plug of each cylinder supplies a spark to the combustion chamber of the fuel mixture, and ignition occurs. For ignition, current must be supplied to all spark plugs, only then will the engine start and the car begin to move. If not, the vehicle will not move.

But still, sometimes the Priora, like any other vehicle, becomes unusable. Repairs can be carried out at a service station, or you can do it yourself.

Sometimes the engine of a Lada Priora car starts to misfire, in other words, the engine does not perform its functions at full capacity. The reason for this behavior lies in the electric ignition coil. The ignition system of this car is unusual. Each spark plug has its own coil, therefore there are 4 of them. This means that the ignition can be slowed down four times more often than on other cars. Once one coil fails, the cylinder associated with it stops working. Individual ignition coils for any cylinder require no adjustment because they have no moving parts. In a Priora car, the ECU informs the driver about a malfunction and monitors the distribution and moment of spark formation. In the cylinders in which the compression strokes end, sparking occurs. Precise pulses are supplied to the ECU from the crankshaft and camshaft position sensors, after which the control unit detects the sequential firing of the ignition coils. The information transmitted to the system allows you to manage the entire process:

frequency of rotational movements of the crankshaft;
engine load, air consumption;
coolant temperature;
position of the crankshaft and camshaft;
detonation.

If you have problems with the coils, you need to seek help from a specialist. To check the ignition coil on a Priora you need a special tool - a multimeter.

If, while in a car on the road, the driver hears that the engine is starting to stall, he will have to try to correct the situation himself. The coil may pass current, in which case it needs to be insulated. For insulation, it is better to use heat-shrinkable tubing.

Removing and installing a coil on a Priora

To change the ignition system element in a 16 valve engine, follow these steps:

Park the car level, securing it with the hand brake.
Raise the hood and remove the negative from the battery.
Undress the motor by removing its plastic protective casing.
Find the spare part you need, and then the wire block connected to it.
Squeeze the wire block clamp and turn off the power.
Using the 10th key, unscrew the bolt that secures the part to the metal.
Carefully remove the spool, trying to move it vertically. It would be a shame to damage the wiring at the very last moment.
Remove the faulty part and replace it with a new one. Tighten the fastening bolt, connect the wire block and place the negative on the battery. Check functionality.

Types of coils

Which spark plugs are suitable for a Priora car? It is worth remembering the quality of the parts and their condition. Sometimes spark plugs have an incorrect gap; it should not be less than 1 mm. To be sure of the performance of your car, it is better to change the spark plugs and ignition coil at the same time

This is important because the contact mechanism gradually wears out and becomes unusable, as a result of which sparking is disrupted and fuel consumption increases.

Replacing spark plugs is as follows:

The spark plugs are screwed in using a special wrench so that the O-ring fits into place. After this, you need to tighten the spark plug 90 degrees with a wrench. When installing old spark plugs, they are tightened only 15 degrees.

Causes

The LADA PRIORA engine has problems with the 16 valve injector for various reasons. To find out the specifics, the motorist needs to know the design features of the power unit, as well as have some vehicle repair skills.

Lada Priora 16 valves.

So, LADA PRIORA has 16 valves and a triple engine, what could be the reasons for the effect:

Poor quality fuel.
Malfunction in fuel supply elements.
Malfunction of air intake units.
Malfunction in the ignition system.
The problem lies in the electronic part of the car.

Nutrition

A missed flash may occur due to the fact that there is simply nothing there to burn, that is, to flash. So first, start the engine. When it has been running for a couple of minutes, turn it off and remove the spark plug. If it turns out to be dry, then the reason is the lack of fuel. There may be several reasons for this situation:

The most common cause of 16 valves on a Priora is damage to the injector winding. You can check this by removing the cover and manifold. Then measure the resistance on the injector winding; it should be within 15-15 Ohms. If it is faulty, it should be replaced. Read more about how to do this in the article “How to check an injector nozzle”;
Another reason is a clogged injector. This usually happens when using low-quality fuel. You can also “clog” these engine elements yourself by pouring various cleaners into the tank. They partially destroy sediments. Which, in the form of a suspension, enter the injector, where they get stuck in the nozzles. To fix the problem, you need to flush the injectors. You can do this yourself without removing them from the engine.

Ignition system

One of the options for why the tripping occurred is a problem with sparking. So, failure of a spark plug or one of the high-voltage wires leads to the fact that the engine begins to stall. Therefore, it is necessary to diagnose these elements for operability.

Electronic problems can also cause tripping.

Another structural element that needs to be checked is the injector, since the problem may be hidden in this element.

Last but not least, the electronics are where faults occur. So, a problem with sensors or the electronic control unit of the power unit can cause tripping.

To carry out repair and diagnostic operations, you will need not only standard tools, but also a diagnostic laptop PC, as well as a cable connecting to the ECU - K-line.

After connection and synchronization, you can determine what errors exist, or perhaps one of the sensors responsible for the normal operation of a particular node has failed. After the repair, it is recommended to reset all accumulated errors.

Ignition

But it may turn out that when you unscrew the spark plug, you will see that it is wet. This indicates there is no spark. As a result, fuel combustion does not occur. The ignition is checked in the following order:

First, let's visually evaluate the candle. It should be brown-sand color. If it is darker, then it may be faulty. It is advisable to check it on a special stand. The spark should be blue and white. If it is yellow or red, then this is a bad sign. You can, of course, try to clean it with sandpaper, but this may not bring the desired effect;
Try using another spark plug and check how the engine runs. If everything returns to normal, then the cause has been found. Also check the high voltage wire;
After this, check the ignition coil. It is the weakest ignition part in the Priora. To check, we reset errors from the ECU. And with the ignition off, they swap the supposedly non-working ignition coil with the obviously working one. The engine starts for a couple of minutes. The diagnosis is repeated. If the flash miss “migrated” along with the coil, the problem is in it. Replace it with a new one.
