P2567
Direct Ozone Reduction Catalyst Temperature Sensor Circuit
Emissions (ozone reduction catalyst)
Generic OBD-II
Medium
What it means
P2567 means the computer sees a circuit fault in the temperature sensor for the direct ozone reduction catalyst, an emissions device found on some vehicles. The sensor monitors catalyst temperature, so the code reflects a sensor or wiring problem rather than an engine-running fault. The car drives normally but may fail emissions testing.
Medium
Can I keep driving? Safe to drive short-term — this is an emissions-monitoring sensor. The engine runs normally, but the fault should be repaired to pass emissions testing.
Common symptoms
What you'll notice
- Check-engine light on
- No change in how the engine runs in most cases
- May fail an emissions/readiness test
- Possible related emissions monitor codes
Common causes
Most likely first
- Faulty direct ozone reduction catalyst temperature sensorLikely
- Open, shorted, or high-resistance wiring in the sensor circuitCommon
- Corroded or loose sensor connectorCommon
- Heat-damaged harness near the exhaust/catalystLess often
- Rarely, an ECM faultLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and check the sensor's live reading with a scan tool.
- Inspect the sensor connector and wiring for corrosion, opens, or heat damage.
- Compare the sensor's resistance and signal against the manufacturer's spec.
- Repair wiring or connector faults before replacing the sensor.
- Replace the temperature sensor if it's out of range with good wiring, then clear and re-test.
FAQ
Quick answers
Is it safe to drive with P2567?+
Yes, for normal driving. It's an emissions-monitoring sensor, so the engine runs fine, but repair it to pass an emissions test.
Can I just clear P2567?+
It returns until the sensor or wiring is fixed, and emissions monitors won't be ready. Repair it first, then clear.
