P2567
Direct Ozone Reduction Catalyst Temperature Sensor Circuit
- Severity
- Low
- Driving
- No driving restriction
A fault in the direct ozone reduction catalyst temperature sensor circuit. A direct ozone reduction catalyst is a coating on the radiator, not part of the exhaust. Air passing through the radiator is converted from ground-level ozone into oxygen, so the vehicle cleans a little of the air it drives through. It is fitted to a small number of very low emission vehicles and has no effect on how the engine runs.
Possible causes
- CommonFailed sensor
- CommonCorroded or water-ingressed connector at the front of the vehicle
- CommonWiring damage from stone strikes or road debris
- PossibleRadiator coating damaged or contaminated
- PossibleLoss of reference voltage or earth
- PossibleFront-end damage or repair disturbing the wiring
What you might notice
- Check engine light on
- Failed emissions test in jurisdictions that test for it
- No effect on how the car drives
- No symptom the driver notices
What to check, in order
- Inspect the connector and wiring at the front of the vehicle. This equipment sits behind the grille and takes stone strikes, water and road salt.
- Ask whether the vehicle has had front-end damage or a radiator replaced. A replacement radiator without the coating, or with the sensor left disconnected, produces exactly this.
- Check the reference voltage and earth at the sensor.
- Check the radiator face is clear of debris.
- Note that this system has no effect on how the engine runs, so it can be dealt with at convenience unless an emissions test is due.
