P2314 Volkswagen Code - Ignition Coil 5 Secondary Circuit

Quick Answer

The current flow, or dwell, through the primary ignition coil is controlled by the Powertrain Control Module (PCM) by providing a switched ground path through the ignition coil driver to ground. Common causes include Faulty spark plug or coil boot, Faulty Ignition Coil 5, Ignition Coil 5 harness is open or shorted. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2314 Volkswagen Description

The current flow, or dwell, through the primary ignition coil is controlled by the Powertrain Control Module (PCM) by providing a switched ground path through the ignition coil driver to ground. When the ignition coil driver is switched on, current rapidly builds up to a maximum value, determined by the coil inductance and resistance. When the current is switched off, the magnetic field collapses which induces a secondary high voltage surge and the spark plug is fired. This high voltage surge creates a flyback voltage which the PCM uses as a feedback during the ignition diagnostics. The PCM continuously monitors the ignition system for concerns. The P2314 code sets when the PCM detects a short to voltage in the circuit.

Frequently Asked Questions about P2314 Volkswagen Code

1. What does the OBDII code P2314 mean on a Volkswagen?

P2314 indicates a fault in the ignition coil 5 secondary circuit, which is responsible for providing the spark necessary for combustion in cylinder 5.

2. What are the symptoms of code P2314 in a Volkswagen?

Common symptoms include engine misfires, rough idling, reduced engine performance, poor fuel efficiency, and the check engine light being illuminated.

3. What causes the P2314 code in a Volkswagen?

Common causes include a faulty ignition coil, damaged spark plug, wiring issues in the ignition coil circuit, or a malfunctioning engine control module (ECM).

4. Can I drive my Volkswagen with the P2314 code?

Driving with this code is not recommended, as it can cause engine misfires that may lead to further damage, such as a clogged catalytic converter.

5. How do I diagnose the P2314 code in my Volkswagen?

Start by inspecting the ignition coil and spark plug for damage, check the wiring and connections to the ignition coil, and use a multimeter to test for proper voltage and continuity in the circuit.

6. How do I fix the P2314 code on a Volkswagen?

Repairs may include replacing the faulty ignition coil, installing a new spark plug, repairing damaged wiring, or reprogramming or replacing the ECM if necessary.

7. How much does it cost to repair the P2314 code in a Volkswagen?

Costs vary but typically range from $100 to $400, depending on whether you need to replace the ignition coil, spark plug, or repair wiring.

8. Can a bad spark plug cause the P2314 code?

Yes, a worn or damaged spark plug can cause issues in the secondary ignition circuit, leading to the P2314 code.

9. What tools are needed to fix the P2314 code?

You may need an OBDII scanner, multimeter, spark plug socket, and basic hand tools to diagnose and repair the issue.

10. Will clearing the P2314 code fix the problem?

Clearing the code may temporarily turn off the check engine light, but it wonâ€™t resolve the underlying issue causing the fault. Proper diagnosis and repair are required.
