Q: What does code P2567 mean?

Direct Ozone Reduction Catalyst Temperature Sensor Circuit. P2567 indicates that the powertrain control module has detected an abnormal signal from the direct ozone reduction catalyst temperature sensor, which monitors the temperature of a specialized catalyst used to reduce ozone-forming emissions. The computer compares the sensor's voltage or resistance against expected values and sets this code when the reading falls outside the valid range or behaves erratically.
