The Ignition Coil D Primary Control Circuit High fault code (P2310) indicates that there is a high voltage present in the primary control circuit of the ignition coil D. This circuit is responsible for controlling the ignition timing and firing of the spark plug, which is crucial for the engine's performance.

What are the symptoms of the P2310 code?

Common symptoms associated with P2310 include:

• Engine misfires or rough idling
• Reduced engine performance and power
• Difficulty starting the engine
• Increased emissions due to incomplete combustion
• Check Engine Light illuminated on the dashboard

What causes the P2310 code?

This code can be triggered by several factors, including:

• A faulty ignition coil D
• Wiring issues such as shorts or open circuits in the ignition coil D circuit
• Poor connections or corroded connectors in the ignition system
• Issues with the Engine Control Module (ECM) that controls the ignition system

How to fix P2310?

To resolve the P2310 error code, you can follow these steps:

1. Inspect the ignition coil D for any visible damage or wear.
2. Check the wiring and connectors leading to the ignition coil D for shorts, opens, or corrosion.
3. Test the ignition coil D with a multimeter to ensure it is functioning properly.
4. If needed, replace the faulty ignition coil D.
5. Clear the fault codes from the ECM and perform a test drive to see if the code returns.
