• Solutions

The P2317 fault code indicates a problem with the ignition coil's secondary circuit. This code typically arises when the Engine Control Module (ECM) detects an improper voltage or resistance in the circuit associated with the ignition coil. The ignition coil is responsible for transforming the battery's low voltage to the high voltage required to ignite the fuel-air mixture in the engine's cylinders.

What are the symptoms of the P2317 code?

Symptoms that may accompany the P2317 fault code can include:

• Engine misfires or stumbling during acceleration.
• Reduced engine performance and efficiency.
• Difficulty starting the engine or stalling.
• Illuminated check engine light on the vehicle's dashboard.

What causes the P2317 code?

Common causes of the P2317 fault code include:

• Damaged or corroded wiring and connectors in the ignition coil circuit.
• Faulty ignition coil that cannot produce the required voltage.
• Poor ground connection or damaged connectors.
• Issues with the Engine Control Module (ECM) itself.

How to fix P2317?

To resolve the P2317 fault code, follow these steps:

1. Inspect the ignition coil wiring and connectors for signs of damage or corrosion.
2. Test the ignition coil itself for proper resistance and functionality; replace if faulty.
3. Check for good ground connections and ensure all electrical contacts are secure.
4. Clear the fault code and perform a test drive to ensure the issue is resolved. If the code reappears, further diagnostic tests may be needed.
