What Does P2567 Mean?
The PCM has detected a problem with the electrical circuit for the Direct Ozone Reduction catalyst temperature sensor. This sensor monitors temperature in a specialized emissions control component designed to reduce ozone-forming NOx emissions.
Common Causes
35%
Failed temperature sensor element
30%
Open or short circuit in sensor wiring harness
20%
Corroded or damaged sensor connector
10%
Exhaust leak affecting sensor readings
5%
PCM internal circuit fault
Diagnostic Steps
1
Step 1: Locate the Direct Ozone Reduction catalyst temperature sensor in the exhaust system
2
Step 2: Inspect sensor connector for corrosion, damage, or moisture intrusion
3
Step 3: Measure sensor resistance with engine cold and compare to manufacturer specifications
4
Step 4: Check wiring continuity between sensor and PCM for opens or shorts to ground/voltage
5
Step 5: Monitor sensor data in live stream during engine warm-up to verify proper temperature response
Estimated Repair Cost
$150 - $450
Parts + labor, varies by vehicle and location
The PCM has detected a problem with the electrical circuit for the Direct Ozone Reduction catalyst temperature sensor. This sensor monitors temperature in a specialized emissions control component designed to reduce ozone-forming NOx emissions.
The most common cause of P2567 (Direct Ozone Reduction Catalyst Temperature Sensor Circuit) is: Failed temperature sensor element
Typical repair costs for P2567 range from $150 to $450, depending on the vehicle, location, and whether you do it yourself or go to a shop.
No immediate safety concerns. Vehicle remains fully drivable but may fail emissions testing and experience reduced fuel economy.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2567 to identify the root cause.
