Trouble P0351 - Ignition Coil “A” Primary/Secondary

Errors p0351, p0352, p0353, p0354 are associated with faults in the ignition system. In particular, ignition coils (coils), wiring or control unit. Problems with the coil are usually caused by shorted turns on the primary or secondary winding or its breakdown. As for the wiring, this can be either a break in individual wires, damage to their insulation, or, as a consequence, a short circuit between them or to ground (housing). The most difficult case is the breakdown of the electronic control unit, in particular, the breaking off of part of the ceramic board with connectors, which is diagnosed by the electronics precisely as errors with numbers p0351, p0352, p0353 and p0354.

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

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 car engine ignition is turned on;
the feedback signal informs the electronic control unit that the device has not worked;
the number of failures of individual ignition coils is constantly growing;
a corresponding error in the ECU memory will be generated when the number of failures reaches 20 in 40 test cycles.

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:

four consecutive ignition cycles have passed during which no malfunctions in the operation of the ignition coil were detected;
the power supply to the ECM was turned off for more than 10 seconds;
The diagnostic code must be cleared with a scan tool.

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

Signs of breakdown

External signs of error codes p0351, p0352, p0353, p0354 include:

activation of the Check Engine warning light on the dashboard;
misfires in one or more engine cylinders (depending on the number of errors), this leads to the engine “troubling”, operating unstably, and having an uneven idle;
drop in engine power and deterioration in the dynamic characteristics of the machine;
problems starting the engine.

Since such signs may indicate other problems with the engine, reading diagnostic codes with an error scanner is mandatory, this will allow you to move on to further specific checks.

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).

System diagnostic methods

There are two ways to identify errors in Grant and its analogues. Both methods have clear advantages and disadvantages.

Self-diagnosis of Lada Granta

The principle of the method is to use standard systems installed on the machine. The procedure does not require connecting additional equipment or studying complex instructions. To perform the check, just follow a simple sequence of actions:

simultaneously hold down the daily mileage reset button located on the dashboard and turn the key in the lock cylinder to position 2;
if everything is done correctly, the machine will go into self-diagnosis mode, all the arrows will make a full revolution and the indicators will light up;
Use the button on the steering column wiper position switch to select the required option;
Information about the firmware version appears first in the list. By clicking on the positions further, you can see the required error combination.

Note!

If, when switching to self-diagnosis, any indicators do not light up, their circuits must be checked first.

The disadvantage of this method is the low accuracy of the indicators. The display displays compressed information about the breakdown, which can only indicate the direction from which to start looking for the problem.

In the most popular versions of ECU firmware, network errors are noted as:

The specified Lada Granta error code indicates the presence of a critical power surge in the on-board network. In 90% of cases it indicates a short circuit or damage to electrical appliances.
You need to check the float sensor in the gas tank and its circuit. There may be a short circuit or damage to the sensor.
The motor has overheated or the antifreeze temperature sensor has broken.
Failure in the power supply circuit of the ambient temperature meter.
Additionally, it indicates overheating of the power plant or incorrect operation of the thermostat. Indirectly affects more complex faults such as cylinder head gasket breakdown.
The pressure in the fuel rail has dropped critically. You will need to check the pumps and the condition of the injectors. A popular error in the first generation Grant engine.
If the brakes have failed or the pads have worn out badly, diagnostics of the modules is necessary.
Severe voltage drop in the on-board network. There may be problems with the battery.

If “E” is displayed on the device, this indicates that the firmware is not working correctly.

Computer diagnostics

The next method involves connecting special equipment to the machine. The bottom line is this:

there is a special connector under the dashboard;
a laptop with the program is connected to the terminal via a special connector;
device pairing begins;
After establishing a stable connection and reading information from the BC, Lada Granta error codes will be displayed in the software window.

If everything is done correctly, special codes are displayed on the monitor. Moreover, each part of the code speaks of its own circuit.

Beginning (letter)

P – the integrity of the electrical wiring is compromised or the sensors are damaged;
C – probably the breakdown is in the suspension units, chassis;
B – problems with the internal equipment of the car;
U – resynchronization of several interconnected circuits is observed.

The following are standard notations:

0 – failure in the OBD 2 module;
1/2 – enterprise code (what this is is known only to the car manufacturer);
3 – malfunction of spare wiring parts.

The next part indicates the serial number of the on-board circuit section where the breakdown is located:

0 – exhaust cleaning device;
1 – motor air supply system;
2 – fuel lines, pumps and injectors;
4 – control devices;
5 – malfunctions or disruption in the operation of additional systems;
7/8 – transmission, chassis.

Next comes another two-digit number - the last part of the index points directly to the system where there is a problem.

Diagnosis and problem solving

Try wiggling and testing the wiring at coil #1 and along the harness to the PCM. If manipulation of the wiring causes misfire, correct the wiring problem. Check the reliability of the contact in the coil connector. Make sure the bundle of wires is not rubbing against anything. Repair if necessary.

If the engine is currently experiencing rough operation, stop the engine and disconnect the #1 coil wire connector. Then start the engine and check the driver signal on coil #1.

Use a voltmeter on the AC current scale in hertz. See if there is a reading between 5 and 20 Hz or so, which indicates the driver is working. If the readings vary, replace the No. 1 ignition coil.

If there is no frequency signal from the PCM in the ignition coil driver circuit, leave the coil disconnected. Check the DC voltage in the driver circuit at the ignition coil connector. If there is significant voltage on this wire, then there is a short somewhere. Find the short circuit and repair it.

If there is no voltage in the driver circuit, turn off the ignition. Disconnect the PCM connector and check the continuity between the PCM and the coil. If there is no continuity, repair the open circuit or short circuit.

If there is a break, check the resistance between ground and the ignition coil connector. There must be endless resistance. Other indicators indicate a short, repair the short to ground in the coil driver circuit.

If you find that the engine is misfiring, the coil fires correctly, but the P0351 code keeps popping up. There is a possibility that the PCM coil monitoring system may be faulty.
