How to check the ignition coil on a Priora (VAZ 2170): testing methods

Automobile: Lada Priora. Asks: anonymous Essence of the question: what are the best ignition coils to buy for Priora? Automobile: Priora sedan standard 2010

The reels are tired. I have already replaced all 4, and again they were sentenced to service. I bought the reels as a set from a store that has certificates for an official dealership. Today I will try to return it under warranty, since all 4 coils are broken.

Therefore, what is better to buy, please tell me the verified article numbers of the coils for the Priora?

Crack on the coil of the first cylinder. This coil will "drizzle".

IKZ device

The Priora coil consists of a primary and secondary winding, between which a core is placed. To contact the spark plug, a spring is used, which is placed in a rubber tip. The IKZ also has a metal screen that protects the coil from high temperatures, because IKZ is installed in the well of the cylinder head, then the temperature conditions there are simply enormous.

The primary winding is wound from thin copper wire with a number of turns of 10,000-15,000.

The secondary winding of the coil consists of 100-150 turns of thick copper wire.

The connection between the coils is electromagnetic.

After reading Will a spark ignite a flame? Not always! I decided to try to do something similar in my car. In addition, several participants in the drive noted the improvement as useful. I purchased capacitors from a TV technician for 20 rubles. per piece because There is no radio parts store, and there was no particular desire to tinker with devices:

I wanted one like McSystem, but these were the only ones I could find. I thought these would work too, the main thing is to connect it correctly and assemble it according to this diagram:

Wrap it well with insulating tape and install it in the car. I’ll take a photo of how it looks in the car later. I haven’t figured out yet whether it was good for my car. I'll take a ride and report back.

I took it for a ride, but the traction is better, the dynamics have increased!

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.

The ignition system uses individual ignition coils for each cylinder. The ignition system has no moving parts, so it requires no maintenance or adjustments.

The ignition system uses spark plugs of the AU17DVRM type or their foreign analogues BOSCH FR7DCU, BERU 14FR-7DU, CHAMPION RC9YC, NGK BCPR6ES.

In the ignition system, the distribution and moment of spark occurrence in the cylinders is monitored by the ECU.

Sparking occurs sequentially in those cylinders in which the compression stroke ends and, accordingly, the order 1–3–4–2 is observed.

The crankshaft and camshaft position sensors supply pulsed “reference” signals to the computer, on the basis of which the computer calculates the firing sequence of the ignition coils.

To accurately control the ignition, the ECU uses the following information:

– crankshaft rotation speed;

– engine load (mass air flow);

– coolant temperature;

– position of the crankshaft;

– position of the camshafts;

Coil characteristics

Most likely, the electronics will signal a malfunction, but sometimes it is difficult to guess the causes of incomprehensible vibrations. Therefore, the first thing to do is to check whether the Priora’s ignition coil is working. It is worth noting that even some diagnosticians do not always quickly recognize a faulty part. Therefore, car enthusiasts have found several ways to check the ignition coil without visiting a service center.

What is the coil for? To ignite the air-fuel mixture in the cylinder, you need a high voltage current, but in a car battery it is low voltage. Thus, the ignition coil is something like a transformer, generating a current with high voltage. Its primary winding consists of only 150 turns, and in the secondary their number is much larger, which allows it to generate pulses using the spark plug as a spark gap.

Current passes through the primary winding and produces a magnetic field. When the starter opens the circuit, the energy stored in the coil is released and the cherished spark appears on the spark plug. The engine started.

To make the magnetic field as strong as possible, an iron core is located inside the coil. The main characteristic of a coil is the resistance value of its windings, which is taken into account when diagnosing ignition. Failure of such an important component threatens to completely stop the engine, not to mention interruptions in operation.

Checking the performance of the coil

№	Examination	Description
1	Visual inspection	We remove the coils from the cylinders.
		First, let's inspect the rubber part. There should be no breaks or cracks on it, and if there are any, it means that the coil has served its purpose and needs to be replaced.
		Then we look inside, see what condition the internal spiral is in, its position.
2	Checking the primary winding of the coils with a multitester (checking Priora coils with a multitester)	Before connecting the device to the coil, its internal resistance must be checked to take into account possible errors.
		We connect the tester to the primary winding. If the device shows no more than 0.5 Ohm, taking into account the measurement error, then everything is fine with this coil.
3	Checking the secondary winding of coils with a multitester	Switch the tester to 2000 kOhm
		We connect the probes to different parts of the coil, observing polarity: the red contact is to the spring under the rubber cap, and the black one is connected to the middle contact of the connector. A working Priora ignition coil shows a secondary winding resistance of 342 kOhm. A faulty tester will show infinity.

You need to remove the coil from its place by disconnecting the negative terminal of the Priora battery. Decorative plastic is removed from the motor. Then you need to press out the plastic clamp and disconnect the coil from the wiring, after which the fastening bolt is unscrewed with a 10mm wrench and the device is removed from the spark plug well.

Currently, there is simply no trust in standard Priora coils. Some immediately replace them with foreign-made devices, with Bosch products being especially popular. Since the designers have not eradicated this hereditary problem in the Priora model, the owners themselves will have to correct it, investing not so small sums, because Bosch sometimes asks for no less than 1,500 rubles apiece.

Problems with coils can lead to sudden jerks in engine operation, speed surges, and cylinder failures. Therefore, if you have such symptoms, it is better to use the above information and replace the suspicious part before it completely fails. It also happens that the coil has not yet broken, but is already malfunctioning. This does not necessarily mean that a replacement is needed; some repairs will do, or rather cleaning of water condensation and dirt.

Experienced drivers have verified that after a couple of hours of painstakingly cleaning the coils, the motor stops tripping and works like new. It turns out that it did not burn out, but simply passed current in places. Such a nuisance can be eliminated even on the road. It is enough to remove condensation and wipe important parts with gasoline to remove dirt. If you attach heat shrink to the coil, there will never be problems with interruptions again, and Priora will not spoil the mood of its owner.

Sometimes coils fail when the spark plug gap is incorrect. Checking the performance of the coil on a Priora car can be easily done by turning the crankshaft. To do this, you need to relieve the pressure in the fuel system and remove the fuel pump fuse. Then we remove the coil, insert a spark plug into its rubber tip, and connect the wires to the coil itself.

After this, we carefully place the experimental spark plug on the cylinder block, ensuring contact between the spark plug and the mass. Do not touch the spark plug coil with your hands to avoid getting an electric shock. Now you need to turn the crankshaft. An assistant does this while you look carefully at the candle. A spark should appear between its electrodes when the starter is turned on and the shaft is turned. This is an indicator of her work.

You can check the coil power circuit. You need to take the multitester mentioned above and connect its probes to its terminals. If you turn on the ignition at this moment, the tester should show a voltage equal to that at the battery terminals. Otherwise, it is necessary to check the circuits for opens and shorts. If the power and control circuits are working properly, but when checking there is no spark on the working spark plug inserted into the tip, then the coil is faulty and will have to be replaced.

Tip repair

High-quality coils for a Priora car can withstand from 50 to 100,000 km. To increase the life of the coils, you need to prevent engine oil from coming into contact with them.

A cracked ignition coil tip is a common problem. However, you can return the coil to working condition by making repairs on your own, provided that the coil itself has not burned out. This will require a degreasing wipe, a silicone ignition coil O-ring (new), a new tip and silicone sealant. The whole procedure will take a couple of minutes.

Remove the old tip. If the o-ring is damaged, remove it too. To install the tip, its skirt is turned inside out. We take the previously prepared sealant and apply it to the lower part of the tip with a cotton swab. We do this slowly so that there is no excess sealant left around the edges. We put the tip on until it stops.

We wait a while for the sealant to fix the part. We wipe the entire coil with a degreasing cloth, which is now brought back to life. Pay attention to the contact spring; it should move freely in the tip cavity. The necessary parts for the job can be purchased at car markets and online stores. Good luck!

Maintenance frequency of car generator bearings

When servicing the unit, you need to know which bearings are on the generator, and which race of each of them is pressed into place. To extend the time between overhauls, bearings are lubricated at the time of installation at the factory or when replaced by the user. It is believed that this amount is sufficient for the entire life of the rolling elements.

The frequency of bearing replacement is determined by ear:

• if the generator is noisy, it means the clip has worn out;
• Before jamming, the generator bearing hums for quite a long time, so the owner usually has enough time not to let this happen.

Design features of the generator are:

• one bearing is called the front bearing, since it is pressed into the corresponding (front) generator cover by the outer race;
• the second one is put on the shaft with tension on the reverse side, called the rear one, and is located near the commutator group;
• Before changing standard rolling consumables, you need to prepare a special tool;
• To get to the rolling parts, you will first have to remove the generator and then completely disassemble it.

For example, the front bearing can be knocked out, then a new rolling element can be installed in the mounting hole without a puller

It is important that the external dimensions match. It will not be possible to pull the rear bearing off the shaft in this way; a puller will be required.

But you can put on a new standard product by tapping a hammer on a sleeve of a suitable size or an old bearing.

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.

Trouble the engine: why is it dangerous?

This is a rather critical phenomenon, especially if the unit begins to vibrate during acceleration.

This behavior of the engine is especially dangerous when the driver decides to overtake, but there are cars in the oncoming lane. In the process, while the motor is running, the engine power is significantly reduced. The compression ratio decreases - there may not be enough dynamics to successfully complete the maneuver.

Considering that the Lada Priora has been manufactured since 2007, there are often instances where the engine knocks like on an old car 20 years ago. This is an engine running on three cylinders. It may have the latest firmware, but if the Lada Priora has a bad engine, then such a car will not have much life left.

Symptoms of a bad coil

There are many symptoms of coil failure and sometimes it is very difficult to determine that the coil is to blame. If such symptoms appear in your car, then you should pay attention to the ICD.

Signs of coil failure:

• One of the cylinders does not work;
• The car does not develop power;
• Jerking when pressing the gas pedal sharply;
• The engine shakes at idle;
• Increased vibration at idle;
• Floating speed;

It should also be noted that if the ignition coil is faulty, misfires will appear in the cylinders, as a result of which the ECU will turn off the operation of the faulty cylinder and signal this by turning on the “Cheek Engine” lamp. When “Cheek Engine” appears on the car, it is necessary to diagnose the system. If there are misfires, the ECU will display errors 0301, 0302, 0303, 0304. Where the last digits of the codes are the cylinder number.

It is not recommended to operate a car with a faulty ignition coil; this can lead to failure of the catalyst.

Signs of Engine Cylinder Failure

When driving, the engine begins to pull poorly. Work intermittently. However, at idle it seems to run smoothly. At speeds, if the neutral gear is engaged, there are no interruptions either. But as soon as you start moving, the engine shakes. Speed ​​is gained pl

The electronic injection system is designed in this way. That it will compensate for the lack of operation of one cylinder. If you are supposed to maintain a certain number at idle. Even if the cylinder is not working, the electronic unit will give a command to increase the speed. And compensates for the loss of one cylinder. Also, as the speed increases, the injectors will begin to supply more fuel to the remaining cylinders than usual. The absence of one cylinder will not be noticeable. It's worth starting to move. The electronic control unit will also equalize engine speed by increasing the fuel supply to the working cylinders. But the loss of power will already be visible. Three cylinders are not four. The engine will choke. The sound of the engine will change. And there will be no pleasant acceleration like when 4 cylinders are running. Diagnostics involving a tester is expensive. Moreover, a faulty coil can be detected directly on the car.

Description of the ignition coil

Let's start with a description of automotive short circuits. First of all, it is necessary to consider the device, as well as the operating principle of the unit on an engine with 8 or 16 valves.

Design and designation of the main elements of the NGK ignition coil

Design and principle of operation

Every car enthusiast knows that the main function of the short circuit on the Lada Priora is to ignite the combustible mixture, which is necessary to start the power unit. To ensure the mixture is ignited, a very high voltage is generated in the short circuit, amounting to 40 thousand volts. The short circuit itself is a transformer device designed to increase the low voltage produced by the battery. According to its design, the short circuit of a 16-valve engine consists of two windings - primary and secondary, which are wound using a copper wire on a steel core.

First, the primary device is wound onto the core, and the secondary device is wound on top of it. This design is protected by a special housing. If the primary winding contains about 150 turns, then the secondary winding will have more than one thousand of them. There are no high-voltage cables in the short-circuit design, since they are put on the spark plug.

When the powertrain control unit transmits a signal to the primary winding, a magnetic field is generated around the core. Ultimately, it contributes to the formation of high voltage on the secondary winding. As for the spark plug, at this moment it ignites the combustible mixture in the cylinders of a 16-valve engine. The short circuit is equipped with a protective housing, and inside the structure there is a special spring with a diode. The latter is designed for promptly cutting off high-voltage signals (the author of the video about the node malfunction is the IZO)))LENTA channel).

Types of coils

Let's briefly consider the main types of short circuits for cars:

1. General short circuit, this type is one of the most common. It can be used in both contact and non-contact systems, as well as electronic systems with a distributor.
2. Individual type of short circuit. Designed for use in electronic systems. By design, this type also consists of primary and secondary windings, only they are located in reverse - first the secondary, then the primary. Also, such short circuits can use electronic components to ignite a combustible mixture.
3. Dual type, such short circuits are also often called two-terminal. Such units are used in various electronic systems. The key difference in the design is the presence of two high-voltage cables, designed to ensure the formation of a spark in two cylinders simultaneously.

Symptoms of a problem

The ignition coil on a Priora on a 16-valve engine, like any other mechanism, sooner or later fails.

The driver can recognize that this device needs replacement or repair by the following symptoms:

1. The operation of the power unit as a whole is disrupted. The 16-valve engine begins to vibrate, its power drops, and when you press the gas pedal it will be difficult to accelerate. In addition, the engine begins to stall. The same signs also appear with inoperative spark plugs, so they need to be checked first.
2. While trying to accelerate, the driver will notice that the vehicle begins to jerk. Shocks also appear when driving at low speeds.
3. Another symptom is the presence of cracks or traces of breaks in the insulation.

Checking the ignition coil

There are two reliable ways to check IKZ: visual inspection and checking with a multimeter.

It should be noted that the IKZ check is similar for all Lada cars with a 16-valve engine, i.e. the check on cars such as LADA Vesta and X-ray will be the same.

In order to check the ignition coil, it must be removed from the car.

Removing IKZ:

• Disconnect the negative terminal from the battery.
• Remove the decorative plastic trim.
• We unscrew the coil we need with a “10” or Torx E8 head.
• Remove the coil plug and remove it.

Visual inspection

After the coil is removed, it must be carefully inspected. The rubber tip should not have tears or cracks. The plastic part must not be melted or cracked. The contact spring must be in the correct shape without oxidation or rust.

Crack in the coil

Cracks in the coils or tears in the rubber cap will direct the spark to the engine body, therefore, no current will be supplied to the spark plug, which will lead to misfires.

Cracks in the rubber band

If such visual faults are detected, the coil must be replaced.

Checking with a multimeter

Testing with a multimeter is divided into two stages. Checking the resistance of the IKZ itself and checking the control voltage of the IKZ (checking the voltage on the IKZ power supply block).

Let's start by checking the voltage at the IKZ power supply.

To do this, set the switch on the multimiter to constant voltage.

Turn on the car ignition

On the block in connector number 3 we take a measurement (we connect one multimeter probe to the motor body and the other to pin number 3) the voltage should be at least 12 volts. If the voltage is less, this means that the battery is discharged or the ECU controller is faulty.

Checking the IKZ resistance

In order to check the resistance of the IKZ, you need to use a multimeter. It should be noted that resistance measurements must be carried out on a cold engine, because The resistance of the coil windings strongly depends on its temperature.

To check the resistance, it is necessary to check two windings, the secondary and the primary.

Checking the primary winding of the IKZ

When checking the primary winding of the IKZ, it is necessary to set the resistance readings on the multimeter, namely 200 Ohms. Since the resistance readings on the primary winding are not large, and the error of the device is possible, you first need to find out the error of the multimeter. In order to find out the error, you need to close the probes together, the value that will be reflected on the multimeter screen will be the error.

In this case, the instrument error is 0.7 Ohm

Next, we connect the multimeter probes to contacts 1 and 3 (the outermost contacts of the IKZ) and obtain resistance readings. From these readings we subtract the multimeter error and get the true value of the resistance of the primary winding.

Ideally, the resistance of the primary winding should be about 1 Ohm, or better yet 0.

In this example, the reading is 1.1 Ohm without taking into account the error; from 1.1 Ohm we subtract 0.7 Ohm to get 0.4 Ohm. Verdict: the primary winding of this IKZ is in working condition.

Checking the secondary winding of the IKZ

In order to check the secondary winding of the IKZ, set the multimeter to 2000 kOhm.

We connect the red multimeter probe to the spring, and the black one to the middle contact on the IKZ (pin 2). We look at the readings of the device; on a working coil, the resistance of the secondary winding should be in the range of 300-400 kOhm.

As we see, the readings of the secondary winding are also within the normal range. It follows that this IKZ is working.

If the readings are too high, you can try removing the rubber cap and spring from the coil and cleaning the contact patch, then measure the resistance directly again without the spring. If the resistance reading still does not decrease, you should think about replacing the ICP.

The easiest method to detect a faulty ignition coil, without any devices or instruments. This is a reversal of the IKZ.

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.”

Benefits you shouldn't ignore

Along with optimizing his car, the owner, with a new ignition, additionally receives a number of special advantages.

Among them:

1. A real opportunity to customize your own engine for any attractive fuel for the car.

2. If you have a car with HBO, an increase in traction and overall power of the car.

3. Complete absence of detonations and knocking noises when picking up speed, even when less than ideal fuel is available.

4. In gasoline-powered cars, fuel burns out much faster, which reduces fuel consumption by an order of magnitude.

5. In cold weather, the car starts much faster and easier.

6. The electronic system does not require total control on the part of the owner, since control is assigned to the built-in display.

7. The machine can be converted and an additional toggle switch can be added to easily switch to one type of fuel or another.

8. With a new type of ignition, the owner receives new options; important parameters are kept at a specifically set level.

9. The starter turns off on its own after the engine starts.

10. You can control the ventilation of the cooling system.

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.
• Fenox IC16085 (STK) – 1,300 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:

1. Secure the car in place and turn off the engine.
2. Remove the negative from the battery.
3. Disconnect the part from the motor, and then connect a fully functional spark plug to it.
4. Turn off the fuel pump.
5. Use protective equipment against electric shock, this is a must!
6. Turn on the ignition and crank the starter. The spark plug should spark during normal operation.
7. 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:

1. Remove the part to be examined from under the hood.
2. Set the measurement switch to the “200 Ohm” position, connect the probes. The display should show “0” or values ​​close to it.
3. 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.
4. 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.

If carbon deposits appear

After 15 thousand kilometers, it is recommended to re-inspect the condition of the spark plugs. Sometimes brownish-yellow carbon deposits can be observed on the surface of the electrodes. This indicates the use of fuel with an octane rating that is not suitable for the vehicle. When the spark plug overheats, the carbon deposits will turn white. Erosion is also possible. The reason may be early ignition timing. Sometimes the candle is simply not screwed on tightly. Also, with early ignition, the electrode itself melts. This spark plug is for replacement only. Which spark plugs are better for Priora 16 cl., see above.

If the car is moving, you should check the part with a tester for functionality. Typically, a gun with a metal tip and cap is used for this. The tip is touched to the thread of the spark plug, and the cap is placed on the terminal for the armor wires. When you pull the trigger, a spark should occur between the electrodes. If it is not there, the element needs to be replaced.

Removing and installing a coil on a Priora

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

1. Park the car level, securing it with the hand brake.
2. Raise the hood and remove the negative from the battery.
3. Undress the motor by removing its plastic protective casing.
4. Find the spare part you need, and then the wire block connected to it.
5. Squeeze the wire block clamp and turn off the power.
6. Using the 10th key, unscrew the bolt that secures the part to the metal.
7. Carefully remove the spool, trying to move it vertically. It would be a shame to damage the wiring at the very last moment.
8. 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.
