• Causes
• Solutions

The P2335 fault code indicates an issue with the ignition coil L secondary circuit. This circuit is responsible for providing the necessary voltage to ignite the air-fuel mixture within the engine's combustion chamber. When this code is triggered, it usually means that there is a malfunction somewhere in the ignition system that could affect engine performance.

What are the symptoms of the P2335 code?

Drivers may notice various symptoms when the P2335 code is present, including:

• Engine misfires or rough idling, indicating incomplete combustion.
• Decreased engine performance, especially during acceleration.
• Illuminated Check Engine Light on the dashboard.
• Poor fuel economy due to inefficient combustion.

What causes the P2335 code?

Several factors can lead to a P2335 fault code, including:

• A faulty ignition coil that may not properly generate spark.
• Short or open circuits within the wiring connected to the ignition coil.
• Bad spark plugs that may cause misfires and affect the coil's performance.
• Problems with the vehicle's powertrain control module (PCM) that may misinterpret data from the ignition system.

How to fix P2335?

To resolve a P2335 fault code, you can follow these steps:

1. Start with a diagnostic scan to confirm the fault code and inspect related trouble codes.
2. Check the ignition coil for any visual signs of damage, such as cracks or corrosion.
3. Test the ignition coil and replace it if it’s found to be faulty.
4. Inspect the wiring and connectors for any shorts, corrosion, or disconnections and repair as necessary.
5. Replace any worn-out spark plugs to ensure optimal performance of the ignition system.
6. Clear the fault codes and conduct a test drive to see if the issue has been resolved.
