P1379 (Volkswagen, Audi, Skoda, Seat) Cylinder 13 – misfire detected

P1379 – OBD-II Trouble Code Technical Description

Trouble code P1379 indicates that a misfire has been detected in engine cylinder 13 in Volkswagen, Audi, Skoda, and Seat vehicles.

What does the fault code mean P1379?

Trouble code P1379 refers to a specific diagnostic code that is used to indicate a problem with a vehicle's engine. In this case, this code means that a misfire has been detected in cylinder 13 of the engine. This can be caused by various reasons such as problems with the ignition, fuel system, or mechanical problems.

Fault code P1379

Possible reasons

Several possible reasons that could trigger the P1379 trouble code:

  • Problems with the ignition system: Defective spark plugs, wires or ignition coil can cause the air/fuel mixture in the cylinder to not ignite properly.
  • Fuel system problems: Insufficient or incorrect fuel supply to the cylinder, possibly due to clogged injectors or problems with the fuel pump.
  • Mechanical problems: For example, cylinder compression problems, worn or damaged pistons, valves or cylinder liners can lead to improper combustion.
  • Problems with sensors: A faulty crankshaft position sensor or camshaft sensor can result in incorrect ignition timing.
  • Electrical problems: A short circuit or broken wires in the ignition circuit or engine control system may cause improper operation.

If a P1379 code appears, it is recommended that you conduct a thorough diagnosis to determine the specific cause and take corrective action.

What are the symptoms of a fault code? P1379?

Symptoms that may occur with a P1379 trouble code may include:

  • Power Loss: Improper combustion in cylinder 13 can result in loss of engine power, especially under load.
  • Shaking and uneven engine operation: A misfire can cause the engine to shake or run rough, especially when idling or accelerating.
  • Braking or stopping the engine: In some cases, if the combustion problem is severe, it can cause the engine to stall or stop completely.
  • Increased fuel consumption: Improper ignition can result in inefficient fuel combustion, which can increase your vehicle's fuel economy.
  • Sparks from the exhaust manifold: In some cases, you may notice sparks or gases escaping from the exhaust manifold, which may be a sign of an ignition problem.

If you experience these symptoms, it is recommended that you have your vehicle diagnosed by a qualified auto mechanic as soon as possible to determine the cause and correct the problem.

How to diagnose a fault code P1379?

The following approach is recommended to diagnose DTC P1379:

  1. Scanning error codes: Use a diagnostic scanner to read error codes in the engine management system. If you receive code P1379, this may be the first sign of a problem.
  2. Checking the ignition system: Check the condition of the spark plugs, wires and ignition coils. Make sure they are in good condition and provide enough and proper spark to ignite the air/fuel mixture.
  3. Checking the fuel system: Check the fuel pressure in the system and make sure that the injectors are functioning correctly. It is also worth checking the fuel filter for blockages.
  4. Checking mechanical components: Perform a compression test to assess the condition of the cylinders and valves. Also check the integrity and functionality of the crankshaft position sensor.
  5. Checking electrical connections: Check the wires and connectors connecting the sensors and elements of the ignition and fuel systems. Make sure they are securely connected and free of corrosion.
  6. Additional tests: In some cases, additional diagnostics may be required, such as checking the operating parameters of the engine management system using specialized equipment.

After diagnosing and identifying the cause of the malfunction, you should begin to repair or replace the faulty components. If you are not confident in your skills, it is better to contact a professional auto mechanic for further service.

Diagnostic errors

When diagnosing DTC P1379, the following errors may occur:

  • Incomplete diagnosis: The error may be that the mechanic is focusing on only one of the possible causes, without considering other potential problems that could also cause this error code.
  • Poor interpretation of data: Sometimes mechanics may misinterpret the data received from the scanner, which can lead to incorrect conclusions about the cause of the error.
  • The need to replace parts without additional diagnostics: Sometimes mechanics may immediately suggest replacing components such as spark plugs or coils without performing a full diagnosis, which can be unnecessary and the wrong solution.
  • Ignoring additional problems: Sometimes a mechanic may focus only on the root cause of the error, ignoring possible related problems that may also be affecting the engine's performance.
  • Insufficient qualifications or experience: Insufficient qualifications or experience of a mechanic can lead to incorrect diagnosis and, as a result, incorrect repair actions.

To prevent these errors, it is important to use specialized equipment. Careful diagnostics will help you avoid mistakes and accurately determine the cause of the malfunction.

How serious is the fault code? P1379?

Trouble code P1379 indicates a misfire in cylinder 13 of the engine, which can be a serious problem with the vehicle's performance. Depending on your specific circumstances, the severity of this error may vary:

  1. Potential performance issues: A misfire can cause the engine to lose power, run rough, or even stop completely in some cases.
  2. Possibility of engine damage: Improper ignition can lead to overheating or other problems that can damage the engine if the problem is not addressed in a timely manner.
  3. Increased fuel consumption: Improper ignition can result in inefficient fuel combustion, which can increase vehicle fuel consumption.
  4. Harmful emissions: Improper combustion can lead to increased emissions of harmful substances in the exhaust gases, which can negatively affect the vehicle's environmental performance.

It should be noted that the severity of the P1379 code depends on the specific cause, engine condition, and other factors. In any case, it is recommended to carry out diagnosis and repair as soon as possible to prevent further problems and ensure normal operation of the vehicle.

What repair will help eliminate the code? P1379?

Resolving trouble code P1379 may require several repair steps, depending on the specific cause of the error. Below are some typical measures that may help resolve this code:

  1. Replacing spark plugs: If the problem is due to faulty spark plugs, they should be replaced with new ones of the type and model recommended by the manufacturer.
  2. Checking and replacing ignition coils: If the ignition coil is not functioning properly, it must be checked and, if necessary, replaced.
  3. Checking and cleaning injectors: Clogged or faulty injectors can cause misfire. They must be checked and, if necessary, cleaned or replaced.
  4. Checking the sensors: Sensors such as the crankshaft position sensor or camshaft sensor should be checked for correct operation and replaced if necessary.
  5. Checking wiring and electrical connections: Wiring and electrical connections associated with the ignition and fuel systems should be inspected for corrosion, breaks or damage.
  6. Additional diagnostics: In some cases, additional diagnostics using specialized equipment may be required to determine the specific cause of the error.

Repairs must be carried out in accordance with production standards and the recommendations of the vehicle manufacturer. If you do not have experience in auto repair, it is recommended that you contact a qualified auto mechanic or auto repair shop for diagnosis and repair.
