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:

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

On which cars is this problem most common?

The problem with code P0351 can occur on different machines, but there are always statistics on which brands this error is more common. Here is a list of some of them:

• Chevrolet (Chevrolet Aveo, Cruz, Lanos, Lacetti, Rezzo)
• Chrysler
• Citroen (Citroen C4, C5)
• Daewoo (Daewoo Matiz, Nexia)
• Dodge (Dodge Ram, Stratus)
• Fiat (Fiat Punto)
• Ford (Ford Mondeo, Taurus, Focus, Fusion, C-Max)
• Jeep (Jeep Grand Cherokee)
• Lexus (Lexus rx350)
• Mazda (Mazda Premasi, Surname)
• Mercedes
• Nissan (Nissan Almera)
• Opel (Opel Astra, Vectra, Zafira, Meriva, Omega)
• Peugeot (Peugeot 206, 307, 406, 407, Partner)
• Renault (Renault Logan)
• Skoda (Skoda Octavia)
• Toyota (Toyota Avensis, Auris, Camry, Corolla, Prius, Rav4)
• Volkswagen (Volkswagen Tiguan)
• Volvo (Volvo v40)
• VAZ 2114
• Gazelle Business
• Zaz Chance
• Lada Granta, Kalina, Largus, Priora
• UAZ Bukhanka, Patriot

With fault code P0351, you can sometimes encounter other errors. The most common ones are: P0102, P0108, P0113, P0118, P0123, P0138, P0174, P0183, P0194, P0340, P0352, P0353, P0354, P1391, P2106, P2195.

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:

• Faulty spark plugs or their wires. Spark plugs can fail either partially (for example, due to contamination of the electrodes) or completely, as a result of which a spark will not appear on the electrodes at all. In rare cases, a P0363 code may also be displayed.
• Ignition coil malfunction. Typically this failure is caused by the primary and/or secondary windings being shorted. Moreover, this can be either an interturn short circuit or a short circuit between the primary and secondary windings. In the first case, usually the voltage generated is not enough to ignite the air-fuel mixture, and in the second, there will be no voltage at all. Often, when a short circuit occurs, the corresponding fuses blow. Another option is a partial failure of the rubber tip of the coil, which causes a spark to simply break through to the body.
• Wiring problems. In this case, there may be breaks: between the control unit and the coil, between the coil and the spark plug, or the supply wiring. In this case, this can be either a complete break in the wires or damage to the insulation section/sections. For example, when rubbing in places of bending, exposure to extreme temperatures, and so on. In any case, diagnostics must be performed using an electronic multimeter, which allows you to find the corresponding damage.
• Control unit malfunction. This is the worst case. As mentioned above, inside the block there is a ceramic plate on which power and signal electrical contacts are installed (the design of the control unit may differ for individual car models). Due to constant overheating, the plate becomes fragile, and sometimes a situation arises when a piece of the plate with contacts simply falls off from its main part.

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).

Errors p0363 and p1304

You can detect these errors if you use a self-diagnostic adapter. Each of them has its own decoding and provides the car owner with certain information about the breakdown that occurred in the car. So, the number 0363 (error code) on 2114 indicates that misfire occurred in one of the engine cylinders and the supply of the fuel mixture to it was stopped.

In most modern cars, an electronic control system automatically stops the flow of fuel to the cylinder if any problems occur in it.

The next error - 1301...1304 indicates that in a specific cylinder (the number of which is equal to the last digit in the error number) there were ignition delays, which are critical for the converter.

Often these errors are accompanied by errors of type 0300 - exceeding the threshold of danger (toxicity) of the exhaust as a result of misfire.

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

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.

Troubleshooting

If during diagnostics an error 0363 of a VAZ 2114 is noticed, then the reasons for this may be the following:

1. Poor quality fuel.
2. Air intake leaking.
3. No spark.
4. Damage or wear to the cylinders.

The first of these problems is quite simple to solve - you should try to refuel with gasoline from other manufacturers, and not the one that is currently used. Despite its apparent simplicity, this method very often helps - after all, as statistics show, more than half of the cases of error 0363 are associated with low-quality fuel.
