The P2567 fault code indicates an issue with the Direct Ozone Reduction Catalyst Temperature Sensor Circuit. This sensor plays a crucial role in monitoring the temperature of the catalytic converter, which helps the vehicle manage emissions effectively. A malfunction in this sensor can lead to increased emissions and potential damage to other components of the exhaust system.

What are the symptoms of the P2567 code?

Symptoms associated with a P2567 fault code may include:

• Check Engine Light illuminated on the dashboard.
• Increased emissions test failure rates.
• Poor vehicle performance including rough idling or stalling.
• Deterioration in fuel efficiency due to improper engine management.

What causes the P2567 code?

Common causes of the P2567 code include:

• Faulty temperature sensor that may be shorted or open.
• Wiring issues such as frayed or damaged wiring.
• Poor connections or corrosion at the sensor or within the control module.
• Fault in the engine control module (ECM) that is failing to interpret signals correctly.

How to fix P2567?

To resolve the P2567 code, follow these steps:

1. Use a diagnostic scanner to confirm the trouble code and check for any additional codes.
2. Inspect the temperature sensor and its wiring for visible damage or disconnections.
3. Test the sensor's resistance and functionality; replace it if faulty.
4. Repair or replace any damaged wiring or connectors.
5. Clear the fault codes from the ECM and take the vehicle for a test drive to check if the light returns.
