Priora ignition module 16 valves where is it located

Car : Lada Priora. Asked by : anonymous The essence of the question : which is the best ignition coil to buy for a Priora? Car : 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".

Story

The ignition system in Lada cars has changed over generations. Earlier cars with carburetor fuel injection used a distributor ignition system, which is quite unreliable and required manual adjustment and frequent maintenance.

The distributor was replaced with the advent of injection engines by a modular ignition system; a spark in such a system was produced by a module consisting of two coils. This system began to use a crankshaft position sensor, which helped the engine control unit determine the top dead center and compression stroke of the fuel-air mixture.

Ignition system

Such a system is a collection of parts that are involved in the process of spark formation in the engine. A spark in an internal combustion engine is necessary to ignite the fuel mixture in the combustion chamber. If the engine loses spark, its operation stops completely.

The Priora ignition system includes the following elements:

These three parts are responsible for the formation of a spark in the Priora engine; failure of one of them entails the loss of spark in a particular cylinder.

Let's look at each part of the car's ignition system in more detail to understand their purpose in more detail.

Spark plug

Spark plugs are used in all gasoline-powered vehicles. It screws into the cylinder head and creates a spark in the combustion chamber, which is necessary to ignite the fuel mixture.

The spark plug is a part with a threaded part that is screwed into the cylinder head; an electrode is placed inside the threaded part that generates a spark. Since the spark plug operates under high voltage, a special insulator is used in the spark plug to prevent breakdown and leakage of voltage.

Ignition coil

As described above, the Priora already uses an individual ignition coil. Such a coil is installed on each cylinder and is responsible for supplying a spark to a specific cylinder. The transition to IKZ made it possible to increase engine power while saving fuel.

The ignition coil is a part in which there are two windings, primary and secondary. A voltage of 12V is supplied to the primary winding, and a voltage of almost 40,000 Volts is generated on the secondary winding. This voltage is necessary for reliable spark formation in the combustion chamber.

Crankshaft position sensor

This sensor is necessary to determine the top dead center of the internal combustion engine, that is, when the compression stroke occurs in the engine, it is necessary to supply a spark in the combustion chamber. This sensor understands when the piston is at the top and sends a signal to the ECU, which in turn sends a signal to the IKZ to form a spark in this cylinder. This is how the fuel-air mixture ignites in a specific cylinder.

This sensor is installed next to the crankshaft pulley and reads readings from it. There are marks on the crankshaft pulley that the DPKV reads and thereby determines TDC.

It should be noted that a breakdown of this sensor or a break in its power supply leads to a loss of spark in the internal combustion engine and the inability to start it.

Checking the ICP with a spark gap

Disconnect the IKZ from the spark plug.
Install a spark gap on the IKZ.
Apply ground (from the battery terminal) to the spark gap using a wire.
Turn the crankshaft with the starter.
If there is a spark, then the IKZ is working.

Let us remind you that you can find a problem in engine operation by independently measuring the pressure in the fuel rail, or by checking the compression in the cylinders.

Misfires on Priora

There may be no spark at the Prior due to a breakdown of the sensor, coil, spark plug or ECU. Failures that lead to loss of spark are quite easy to solve, with the exception of a breakdown in the ECU.

If the spark on a Priora disappears on all 4 cylinders, this indicates a breakdown of the crankshaft sensor in 80% of cases, in the remaining 20% the ECU may fail.

If there is no spark on one of the cylinders, then there may be several reasons - a spark plug, a coil or a transistor in the ECU.

Consider each of the reasons in more detail.

Spark plug

Quite often, low-quality spark plugs can fail after several hundred kilometers or even immediately after installation. It is recommended to purchase only high-quality spark plugs.

Which spark plugs are best for Priora can be read in our article.

You can check the serviceability of the spark plug on a special stand or by trying to replace it with a new one or by installing a suspicious spark plug in the working cylinder.

Ignition coil

Problems with the coil appear practically the same as with spark plugs. One of the windings in it may break or break through the insulation, which causes the coil to malfunction. IKZ Prioras cannot be repaired and if they break down they are replaced with a new one.

You can check the serviceability of the coil by replacing it with a coil of another cylinder or using a special diagnostic device ELM 327.

You can read how to check the coil here.

Crankshaft position sensor

DPKV is installed in a place that is subject to both mechanical and temperature influences. Since the sensor works on the principle of a magnet, and its sensitive part tends to magnetize chips. The formation of chips on the sensor will negatively affect the reading from the crankshaft pulley, which can lead to the inability to determine TDC and, consequently, to loss of spark.

How to spot a fake

A few examples of how to visually distinguish original (high-quality) Bosch ignition coils from counterfeits :

Under the casing of the original, a plastic case is visible (the fake has a metal case).
There are two stamps on the original casing. They are not present on the fake.
The outer edge of the original mounting axle box has a protrusion. There is no protrusion on the fake.
On the fake there is no high voltage symbol (lightning) next to the mounting axle box.
On the original plug, the font is made more clearly, the surface of the plug is better processed.
The coding profile of the counterfeit plug is more rounded.
The fake contacts are noticeably thicker and more rounded.
The original has traces of casting.
The factory number on the original is circled in an oval.
The counterfeit rubber tip does not have a manufacturing date, product type number or logo.
The extreme turns of the contact spring of the original are wound more tightly.

Life hack: Priora car ignition coil for 16 valves, its price and design

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.

How to determine a breakdown

In order to determine the malfunction, you just need to take a closer look at the behavior of the car. Typical signs of problems with ignition coils are as follows:

the engine begins to “trouble”, unstable operation of the power plant is noted, the more time passes from the moment the problem appeared, the worse the engine performs;
The poor performance of the unit is especially noticeable at sub-zero temperatures; the situation more or less normalizes only after the engine warms up. In addition, the problem may occur frequently if the machine is located in an area of high humidity;
when you sharply press the gas pedal on the engine;
There is a special indicator on the instrument panel, the so-called Check Engine. It signals to the car owner that there is some kind of malfunction in the car’s power circuit. You can decipher the indicator readings using the instruction manual that came with the car upon purchase.

Diagnosing a failure of an element is not difficult; it is more difficult to identify which part is not working. Each cylinder in the Priora has an individual coil installed; there is no ignition module on the car. Therefore, you will have to run each of them with a multimeter and check each tip. Special attention should be paid to the caps, because if a problem happens to them, you won’t have to change the part. To identify the problem, you just need to remove the element and clamp it with pliers. If the silicone from which the part is made begins to wrinkle, then the tip needs to be replaced. If, when compressed, it remains even and smooth, then the problem lies in something else.

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.

Other spare parts for VAZ (Lada) Priora

Having found out which ignition coils VAZ (Lada) Priora owners prefer to install, you can look at other popular spare parts for this car. In June 2022, the leaders on PartReview were:

#1 Hola shock absorbers - 16% of votes.
#1 Brembo brake discs - 18% of votes.
#1 TIIR brake pads - 9% of votes.
#1 Shell Motor Oil - 7% of votes.
#1 Nokian Tires - 10% of votes.

You can also find out what VAZ (Lada) Priora owners chose among manufacturers of such spare parts as: Drive belt, Timing Belt, Cooling Radiator, Pump, Thermostat, and others.

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.”

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.

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:

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.

Possible causes of ignition module malfunction

Despite the high reliability and durability of the ignition module, during operation it can fail, like any other mechanism. Among all possible causes of breakdowns, in 9 out of 10 cases the following occur and are diagnosed:

Use of inappropriate components in the ignition system. High-voltage wires are selected based on the parameters of the module, since excessively high or low voltage creates malfunctions or burns out contacts.
Defective or damaged parts, poor quality assembly. Defective components break down faster and damage other components or elements of the system. Practice shows that the selection of high-quality components and their periodic diagnostics allow the module to remain operational for a long time.

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.

Signs of a malfunctioning ignition module

A malfunction of the ignition module is determined by the following symptoms:

Difficulty starting a cold engine due to lack of spark on one or more spark plugs.
Floating engine speed at idle is a situation in which the speed changes without any action on the part of the driver.
Dips in power, which manifests itself during acceleration and driving up a long climb.
Decrease in engine power.
Cylinders 1-4 or 2-3 do not work (engine “troits”).
Indication of the “Check Engine” indicator.

Basic faults

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.

Original or analogue?

There are more than 10 different manufacturers of ignition coils on the market. Depending on this, the price for IKZ can vary significantly. For example, good imported ignition coils for VAZ engines can now be found for 1500-1800 rubles. Cheaper Russian analogues will be 2 times cheaper.

It is worth considering that a fake part will have a significantly shorter service life than the original part. For example, according to reviews from owners, after installing Chinese ignition coils, the “cylinder misfires” error almost immediately appeared and the engine began to tune up. After 500-1000 km, the ignition coils completely failed.

Design and principle of operation

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.

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.

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.
