The P2424 fault code indicates that the catalytic converter in Bank 2 is not performing efficiently. This can lead to increased emissions and a decrease in engine performance. It is essential to address this issue promptly to ensure optimal vehicle operation and compliance with emission regulations.

What are the symptoms of the P2424 code?

Common symptoms related to the P2424 code may include:

• Illuminated check engine light
• Increased emissions during emissions testing
• Decreased fuel efficiency
• Rough idling or performance issues while driving
• Excessive engine noise or vibration.

What causes the P2424 code?

Several factors can cause the HC Adsorption Catalyst to be below threshold efficiency in Bank 2:

• Degraded or failing catalytic converters
• Blockages in the exhaust system
• Engine performance issues, such as misfires or improper air-fuel mixtures
• Contamination of the catalyst due to oil or coolant leaks
• Faulty upstream sensors affecting the performance readings.

How to fix P2424?

To resolve the P2424 fault code, consider the following steps:

• Inspect and replace the catalytic converter in Bank 2 if necessary.
• Clear any blockages in the exhaust system.
• Check and repair any engine performance issues, including misfires or vacuum leaks.
• Replace any faulty sensors upstream of the catalyst.
• Conduct a thorough vehicle diagnostic to rule out any other related issues.
