Trouble P0351 - Ignition Coil A Primary/Secondary - Circuit Malfunction

How does a mechanic diagnose a P0351 code?

When diagnosing this error code, a mechanic will do the following:

1. Reads all stored data and error codes using OBD-II scanner
2. Clear error codes from the computer's memory and test drive the vehicle to see if P0351 appears again
3. If the error code appears again, check the ignition coils as well as the associated wires for wear and damage.
4. Find out whether the fault concerns only one of the cylinders or all cylinders of the engine using a scanner
5. If the fault concerns only one engine cylinder, check the corresponding spark plug and its wire for wear and damage.
6. If a malfunction is detected in all engine cylinders, check the primary winding of the ignition coil
7. If no problem is found, check the ECM

The engine does not start and shows errors P0351 and P0352

Tell me what to do. I have a Nissan Almera 2015 (mileage 101,000t.km.) At first it began to run unevenly, did not develop speed when pressing the gas pedal, fired into the exhaust and then stopped starting (it seizes for 5-10 seconds and stalls, when you press the gas or immediately choke or rev up and stall) Shows error P0351 and P0352. I installed new spark plugs and when I try to start them 5-7 times they turn black. I swapped the coils but the errors remain the same.

shoot into the exhaust and then it won't start

The insulation of high-voltage wires may be damaged. You have swapped the coils, but try installing and starting them with other ones that are known to be good. I don't think your ignition could have gone wrong. And the injectors may also become dirty.

I would dig in these directions.

Actually, I found this on the Internet:

P0351 Malfunction in the primary/secondary circuit of the ignition coil

P0352 Malfunction in the primary/secondary circuit of the ignition coil

I encountered this on two cars during diagnostics - Lada Granta and Lada Kalina. In the first case, the negative terminal of the battery was not screwed on, and they jumped off the terminal while driving. In the second case, it was poorly screwed to the ground on the terminal itself and also oxidized under the contact. In both cases it showed exactly these two errors. Either there is a malfunction or low voltage. There was a second one. After cleaning and tightening and resetting the errors, no more errors came out of the ECU.

You need to check the ground wires to the generator, engine, body and battery itself. Check the power fuses, the contacts may be soured.

Error 1602 - the battery is not working properly or the mains voltage is broken

One of the most popular errors on all VAZ cars is error code 1602. This code means that there are problems in the on-board electrical network, but sometimes it occurs simply due to problems with the on-board computer. The diagnostic system constantly tests the battery, so on a frosty morning you may receive an error code 1602 on your computer screen.

This error does not affect the operation of the engine in the VAZ 2110, but other cars may simply not start with it. If you regularly have this problem, you can solve it by installing different firmware. We strongly recommend using official versions of the software. The error code 1602 itself may mean the following problems and problems:

• low voltage in the on-board electrical network for a number of reasons (there may be additional errors in the sensors);
• dead battery and blocking of car functions (the problem was especially noticeable in the VAZ 2115);
• broken wires of the electrical system at a certain node and the occurrence of short circuits in the wiring;
• malfunction of the generator, insufficient current and constant use of the battery;
• too high load on the on-board system due to the installation of additional equipment (music, for example);
• failure of the sensors that are responsible for measurements in the on-board electrical network of your car

Unfortunately, the last option for the cause of this common code is one of the most popular. If sensors fail, the computer can generate a dozen error codes upon startup. Some codes are simply informative, while others simply prevent the engine from starting and block the operation of the on-board system.

Many buyers of VAZ cars initially install other software, eliminating almost all problems with factory equipment. This eliminates the possibility of problems associated only with the sensors. But today, not all problems of on-board computers of domestic cars have been studied. So there is no point in talking about complete protection against malfunctions of this unit. For Priora owners, we suggest watching a video about error code 1602:

What are the symptoms of a P0562 code?

The main symptoms of error P0562 are:

• Check Engine Light or Warning Light Illuminates, Indicating a Malfunction
• Battery charging warning light comes on
• Having problems with gear shifting
• Reduced fuel efficiency
• Engine stalling at idle

Most of the above symptoms can occur in conjunction with other error codes. If your car engine stalls at idle and won't start again, the problem is most likely a bad battery. If error P0562 appears, it is recommended that you contact a qualified technician to diagnose and resolve the error.

Diagnostics and testing of the electronic gas pedal

VAZ supplies LADA GRANTA cars with an electronic gas pedal (E-gas) to comply with modern environmental standards. If the pedal is malfunctioning (no responsiveness or increased engine speed when changing speed on the gearbox), then before dismantling and checking the unit with a multimeter, read the errors through the OBD2 connector.

Typical errors related to the accelerator pedal:

• The “Check Engine” light came on on the dashboard (error 0504);
• Error: Low/High signal level of the first accelerator pedal sensor.

Removing errors will not help here; you need to eliminate the cause of the breakdown and only then erase the errors. If errors are indicated and the pedal does not work stably, you should adjust the sensitivity of the gas pedal itself, it should become more responsive.

Nuances of self-diagnosis of the VAZ 2114

When carrying out diagnostics at specialized service stations or independently, various results and error codes can be obtained. Not all drivers know that faults can be identified without an on-board computer. An odometer is used for this. A significant drawback of such diagnostics is the addition of error numbers into a single sum. For example, if an error of 8 and 1 occurs, the odometer will display the number 9. The device's memory is not automatically cleared, so error codes will be displayed until manually reset by disconnecting the battery terminals for a few seconds.

Resetting the "checkengine" error

As you can see from the video, the error can be reset by following these steps:

• Turn off the engine, but leave the car's ignition on.
• Disconnect the car battery terminal and wait a few seconds.
• Reinstall the terminal and start the engine.

The error will be reset after these steps, but if it is caused by serious malfunctions in the engine, it will occur again. In this case, the best option would be to contact a service station.

Additional comments for troubleshooting P0562

In rare cases, other than the check engine light coming on, drivers may not notice any signs of a P0562 code at all. Even if there are no noticeable symptoms, it is recommended to contact a qualified professional as soon as possible to diagnose and correct the error, since ignoring the problem for a long time can lead to a number of serious problems. Additionally, if the error code persists and the Check Engine light is on, the vehicle will not pass an emissions test.

Code generation condition

Information about the formation of OBD errors p0351, p0352, p0353, p0354 is recorded in the memory of the electronic control unit when a number of the following conditions are met:

The information provided is relevant for the popular Chevrolet Lacetti car, however, the logic for generating errors in most cars will be similar.

Conditions for clearing code from ECU memory

Errors p0351, p0352, p0353, p0354 are deleted from memory if one of the conditions is met:

The archive of diagnostic error codes itself disappears from the ECU memory after 40 consecutive heating cycles, provided there are no faults.

The most common mistake

The most common error P0133 indicates the inability to fully accelerate

Please note that if the display shows error number P0133, we can conclude that the car has stopped accelerating well. This is due to the fact that the control oxygen sensor requires information about the concentration of the air-fuel mixture to be transmitted to the control unit. The sensor itself is located directly in the exhaust pipe, without touching the catalytic converter. The engine control unit is located behind the oxygen sensor when the closed-cycle operating time has passed. In addition, the composition of the air-fuel mixture itself is directly regulated by increasing or decreasing the pulses that occur when the injector opens.

Since most domestic car enthusiasts cannot afford to purchase a foreign car, the Lada Granta can easily play the role of a high-quality and complete replacement. Therefore, if any errors or malfunctions occur, the owner should find out the cause as quickly as possible and, if possible, try to fix the problem themselves. This will save not only time, but also very significant money that would have to be paid for contacting a service station.

Causes of malfunction

There are five main malfunctions that cause OBD errors p0351, p0352, p0353, p0354 to be generated in the memory of the electronic control unit. Among them:

Another, but rather rare reason why the indicated errors with code p0351, p0352, p0353, p0354 are formed in the ECU memory are the so-called “glitches” of the control unit. In particular, its bugs in its software. This can happen, for example, after reflashing the unit, or after mechanical damage (for example, as a result of an accident).

Let's sum it up

If you own a VAZ car, then you are familiar with the incorrect operation of on-board computers. Often errors are issued for no reason at all, but they interfere with the normal operation of the power unit. Therefore, the best way to protect against most unforeseen situations with on-board computers is to change the software.

In this process, it is important to install the official version of the program without risking the viability of your car. There are known cases when unofficial software killed the entire electrical system of a car, sending incomprehensible commands and signals to all sensors of the on-board system. Also, the setup should be done by a professional. Have you had any problems with VAZ on-board computers?

Causes of error P0562

The most common causes of P0562 are:

• Damage to one or more charging system wires
• Generator malfunction
• Battery self-discharge
• Voltage regulator malfunction
• Damage to connectors or wires to the generator
• Malfunction of the wires coming from the generator to the PCM
• Damage to the B+ battery cable from the generator to the battery
• Malfunction of the battery and its cables
• In rare cases, PCM malfunction
