Replacing ignition coils and spark plugs on LADA cars

May 16, 2018 Lada.Online 54 140 0

According to the technical maintenance regulations for LADA cars, spark plugs are changed every 30,000 km. Depending on the engine, replacing the spark plugs will require removing high-voltage wires or individual ignition coils (ICO). Let's look at this process in detail.

On cars Lada Vesta, XRAY, Largus, Priora, Granta, Kalina, Lada 4×4) all actions are performed in the same way.

Replacing the ignition coil

With numerous and sometimes even minor misfires, the engine may operate unstably, floating speeds will appear, the car may jerk while driving, etc.
To determine which cylinder is faulty, it is necessary to alternately remove the coil power plug from each of them, or rather, disconnect it for a while. If, if one of the cylinders is disconnected, interruptions in operation are still present, then this is where the reason lies. Often, it is the ignition coil of one of the cylinders that leads to the consequences described above. And to replace it, you will need the following tool:

• 10 mm head
• Extension
• Ratchet or small wrench

Coil characteristics

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.

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.

The procedure for removing and installing the ignition coil on a Lada Priora car with a 16-valve engine

Since the vast majority of cars are equipped with 16-valve engines, the whole process will be shown on this particular power unit.

So, first of all, open the hood of the car and disconnect the “-” terminal from the battery. Then unscrew the filler cap.

Also, disconnect the adsorber purge valve by bending its fastening clamp slightly to the side. This valve is located on the right rear side of the cover (in the direction of travel of the car).

Now you can remove the decorative engine cover, since nothing else holds it.

Using a ratchet socket, unscrew the bolt securing the coil we need, as shown in the photo below.

And then we remove this part from the spark plug well.

Since the coil sits quite tightly, you will have to apply at least medium force to remove it from there. And in order to completely release it, it is enough to disconnect the plug with the power wires, after first pressing the latch.

And disconnect it completely, as can be clearly seen in the photo below.

Now you can take a new, known-good ignition coil and install it in the reverse order. The price of a reel for Priora ranges from 900 to 2000 rubles, depending on the manufacturer.

Installation is carried out in the reverse order, after which we connect the plug in place and start the engine to check its operation. If everything is normal, then replace the casing, the canister purge valve and the filler plug. This completes the replacement of this part of the ignition system! If you have any questions, ask them in the comments and discuss them together.

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.

Electrical diagram of the LADA PRIORA car

For all owners of the domestic passenger car Lada Priora, as well as for service auto electricians who repair cars, we offer high-quality color electrical diagrams for your reference, indicating all fuses, relays, fans and other modules. The Lada Priora has a 1.6 liter 16 valve engine, an anti-lock brake system (ABS), and air conditioning. The material is intended for electrical equipment specialists and employees of enterprises involved in the maintenance and repair of automobiles, and can be used in training service station personnel.

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.

Replacing spark plugs

Required

: wait until the engine has cooled down, and also the high spark plug head depending on the engine:

• H4M: "at 14";
• K4M, K7M, VAZ-21129, VAZ-21179, etc. 16cl VAZ engines: “for 16”;
• VAZ 8 class engines: “21”.

1. Depending on the engine: disconnect the high-voltage wire (pull) or remove the individual ignition coil (see above)
2. Clean all dirt from the spark plug well (clean with a narrow, hard brush, then blow with compressed air) to prevent dirt from getting into the engine cylinder.
3. Unscrew the spark plug and remove it from the spark plug well.

1. Screw the spark plug in by hand (without a driver).
2. Tighten the spark plug to 20-39 Nm. (Over-tightening the spark plugs may damage the threads).

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.”

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.

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.

Priora ignition coil 16 valves: which is better

The wires to the ignition coils are an equally important component, which if it doesn’t work, you won’t go anywhere.

Ignition system

An experienced car enthusiast who is faced with an engine running on three cylinders immediately begins to diagnose the spark plugs. The Lada Priora must cool well, otherwise there is a risk of getting burned when unscrewing it. If after a few seconds you turn off the ignition and check the spark plugs, one of them will be wet with gasoline. It is also recommended to separately check each part for the presence of a spark.

In the event of a malfunction, the problem is solved. Sometimes it is enough to press down the potentially faulty one with a cap - the machine will resume normal operation. In general, the ignition system in this car is the most problematic part. If the Priora engine (16 valves) is malfunctioning, you can look for the reasons for a very long time, and diagnostics will not yield anything, even if it is done correctly. And only by replacing all elements can a positive result be achieved.

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.

A few words about choosing reels

According to reviews from experts and owners, the ignition coil is suitable for all BOSCH brands. Its cost is approximately 1500 rubles, but it is worth it. Such products are necessarily sold in individual yellow packaging. The original coils of this company can last more than 100 thousand kilometers.

Any modern car, and the Lada Priora in particular, consists of a body as a formative platform and many units and systems specially installed in this body, which together create an individual model of the car. One such system is the ignition system.

A stable start and smooth, uninterrupted operation of the entire engine depend on its correct installation, high quality parts and sufficient compatibility with other vehicle components. After all, it is through the elements of this system - the ignition coils and spark plugs - that a high-voltage pulse is supplied in the form of a spark to ignite the fuel injected into the cylinder chamber.

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.

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.”

Video “Replacing Priora short circuit at home”

The step-by-step procedure for replacing a short circuit on a Lada Priora car with your own hands is given in the video instructions below (author - IZO channel))) LENTA).

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.

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.

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.

Functionality check

There may be several options:

1. Visual inspection. If there are even small cracks on the short circuit, this indicates that the device is not working. If there are cracks or other damage on the housing, most likely the short circuit has burned out. It is also necessary to inspect the internal components, namely the spiral. If there are defects, the unit is replaced.
2. Another way is to check on the car. The short circuit is removed from the engine, the fuel pump is turned off, a working spark plug is installed in the high-voltage terminal, then you need to try to start the engine. If the short circuit is working, then you will see a spark (the author of the video is Alexander).

Checking with a multimeter - for this, the short circuit must be dismantled in advance. The multimeter must be set to resistance measurement mode at 200 Ohms, then the probes of the device are closed. The calibration number will appear on the tester display; you must write it down.

Next, the following actions are carried out:

1. The multimeter probes should be connected to the short-circuit connector and measure the resistance of the primary element. The tester should show a value of about 0.8 Ohm, you need to subtract the calibration number from it - the resulting value will be the resistance. If there are no values ​​during diagnostics, it can be concluded that the primary winding is faulty.
2. Next, you will need to check the secondary element; for this, the resistance of the multimeter is set to 2 mOhm. The red probe should be installed in the short circuit terminal, and the second black probe should be installed in the middle connector of the block. Diagnostics should show 342 kOhm. In general, it should be understood that the obtained parameters largely depend on. How hot the short circuit was, so it is better to carry out diagnostics on a cold device.

What is an ignition coil (IC)

The system on Priora differs from the well-known scheme installed on carburetor cars. On previous machines, a coil was mounted, the pulse signals were distributed by a distributor that had the necessary settings. Models with an injector, which have an electronic fuel injection system, have a separate coil installed on each cylinder, which supplies a spark only to its spark plug.

The entire process is controlled by an on-board electrical device, whose signal is immediately sent to the coil. To competently manage the process, the ECU uses certain data:

• The crankshaft position sensor transmits pulse signals to the ECU;
• phase - gives a signal about the position of the camshaft. Experts call it a synchronizing sensor;
• tachometer – gives signals about the crankshaft speed;
• Mass air flow sensor - measures air flow, provides a load value to the motor at a set time interval;
• DTOZH – motor temperature indicator;
• DT – knock sensor.

If the conditions are standard, then the ECU controls the operation of the cylinders in mode 1 – 3 – 4 – 2. Simply put, a pulse appears in those cylinders where compression is completed, before the valve opens, fuel is supplied and a discharge arrives, detonation occurs and the work cycle continues. Let's try to figure out how to check the ignition coil on a Priora.
