P2325 Fault Code

Ignition Coil I Primary Control Circuit High

• What does that mean?
• Symptoms
• Causes
• Solutions

The P2325 fault code signifies an issue with the ignition coil 'I' primary control circuit being at a high voltage level. This indicates that the Engine Control Module (ECM) has detected a voltage reading outside the normal range for the ignition coil circuit, which can lead to poor engine performance and misfires.

What are the symptoms of the P2325 code?

Symptoms associated with the P2325 code may include:

• Engine misfires or hesitation during acceleration
• Decreased fuel efficiency
• Illuminated check engine light
• Rough idling or stalling
• Increased emissions due to incomplete combustion

What causes the P2325 code?

Several factors can lead to the P2325 code, including:

• Faulty ignition coil
• Damaged or corroded wiring and connectors in the ignition circuit
• Issues with the ECM or PCM
• Short circuits in the ignition coil circuit
• Poor ground connection to the ignition coil

How to fix P2325?

To resolve the P2325 error code, the following steps can be taken:

1. Perform a visual inspection of the ignition coil and circuit for any signs of damage or corrosion.
2. Check the electrical connections to ensure they are secure and free from debris.
3. Test the ignition coil for proper resistance and replace it if necessary.
4. Inspect the wiring harness for any short circuits or breaks and repair or replace damaged wires.
5. If all components check out, consider reprogramming or replacing the ECM if it is determined to be faulty.
