The P2345 fault code indicates that the engine control unit (ECU) has detected that cylinder 10 has exceeded the knock threshold. This means that the cylinder is experiencing unwanted knocking or pinging sounds due to abnormal combustion. Such knocking can lead to engine damage if not addressed promptly.

What are the symptoms of the P2345 code?

Symptoms associated with the P2345 code may include:

• Engine knocking or pinging noises, particularly under load or acceleration.
• Reduced engine performance and power, making it feel sluggish.
• Poor fuel economy as a result of the engine operating inefficiently.
• Illuminated check engine light on the dashboard.

What causes the P2345 code?

Common causes for the P2345 code include:

• Poor fuel quality that may not support the engine's octane requirement.
• Faulty knock sensor that fails to accurately detect engine knock.
• Mechanical issues such as excessive carbon buildup in the combustion chamber.
• Issues with the ignition system, such as faulty spark plugs or timing problems.

How to fix P2345?

To resolve the P2345 code, consider the following steps:

• Use higher octane fuel to prevent knocking.
• Inspect and replace the knock sensor if it's found to be faulty.
• Clean the fuel injectors and remove carbon deposits from the combustion chamber.
• Ensure that the ignition system is functioning properly and replace any faulty spark plugs.
