Yes, P2567 can be serious. It may indicate a problem that affects drivability, emissions, or long-term engine health. It is recommended to address it promptly.

Can I drive with P2567?

It is not recommended to drive with an active P2567 for extended periods, as it can cause catalytic converter damage or unsafe driving conditions.

Will P2567 clear itself?

P2567 may clear if the fault is intermittent, but it will likely return if the underlying issue is not resolved. Use a scanner to monitor pending and confirmed codes.

P2567 - Direct Ozone Reduction Catalyst Temperature Sensor Circuit

P2567 is a Diagnostic Trouble Code (DTC) indicating a fault related to Direct Ozone Reduction Catalyst Temperature. This code falls within the Powertrain (P) category and is standardized across OBD2-equipped vehicles. When P2567 is stored in the engine control module (ECM), it means the onboard diagnostics have detected a malfunction or out-of-range condition in the Direct Ozone Reduction Catalyst Temperature circuit or system.

What is P2567?

P2567 is a Diagnostic Trouble Code (DTC) indicating a fault related to Direct Ozone Reduction Catalyst Temperature. This code falls within the Powertrain (P) category and is standardized across OBD2-equipped vehicles.

When P2567 is stored in the engine control module (ECM), it means the onboard diagnostics have detected a malfunction or out-of-range condition in the Direct Ozone Reduction Catalyst Temperature circuit or system.

Common Symptoms

Reduced engine power
Sulfur/rotten egg smell from exhaust
Failed emissions test
Check Engine Light steady

Possible Causes

Failed catalytic converter
Exhaust leak before converter
Rich fuel mixture damaging catalyst
Engine oil or coolant contamination

Step-by-Step Diagnosis

Connect an OBD2 scanner and confirm the code is present. Note any additional codes.
Review freeze frame data to understand engine conditions when the code was set.
Visually inspect the Direct Ozone Reduction Catalyst Temperature and related wiring harness for damage, corrosion, or loose connections.
Perform a wiggle test on wiring while monitoring live data (if applicable).
Use a multimeter to check sensor/actuator resistance, voltage, and ground integrity.
Compare live data readings to factory specifications.
If circuit-related, trace the wiring diagram and test for opens, shorts, or high resistance.
Clear the code and perform a road test to verify repair.

Recommended Repairs

Replace or repair the faulty Direct Ozone Reduction Catalyst Temperature if testing confirms failure.
Repair any damaged wiring, connectors, or terminals. Ensure proper routing and secure mounting.
Clean components (throttle body, MAF sensor, EGR valve) if contamination is present.
Update ECM/TCM software if a technical service bulletin (TSB) applies.
Replace related fluids (transmission fluid, coolant) if degraded or incorrect.
Verify repair by clearing codes and completing an extended road test under various conditions.
