Direct Ozone Reduction Catalyst Temperature Sensor Circuit Range/Performance
This code means that a sensor in the car is not working right. This sensor helps the car clean the air, and when it doesn't work, the car might not be as clean as it should be.
The P2568 code indicates a problem with the temperature sensor circuit for the direct ozone reduction catalyst. This sensor helps monitor the temperature to ensure the catalyst is working efficiently.
The Direct Ozone Reduction Catalyst is part of the vehicle's emission control system. The temperature sensor in this system monitors the catalyst's temperature to ensure it operates within its optimal range. A P2568 code is triggered when the sensor's output is outside the expected range, indicating a potential issue with the sensor or its circuit.
• Use an OBD-II scanner to confirm the code.
• Inspect the temperature sensor and its wiring for damage.
• Test the sensor's output with a multimeter.
• Replace the faulty temperature sensor.
• Repair or replace damaged wiring or connectors.
• Replace the catalytic converter if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Toyota Prius
• Honda Civic Hybrid
• Chevrolet Volt
• Regular maintenance checks
• Ensure proper fuel quality
• Inspect emission control components periodically
Sensor Issue
• Have the vehicle inspected by a professional.
• Avoid ignoring the Check Engine Light.
• Consider regular emissions testing.
Check with your vehicle manufacturer for specific warranty coverage on emission components.
This code typically appears in vehicles with advanced emission control systems designed to reduce ozone emissions.
Moderate – While the vehicle may still be drivable, emissions may increase, and fuel efficiency could decrease.
Driving with increased emissions may not comply with local environmental regulations.
• Engine at operating temperature
• Vehicle in a controlled environment
The temperature sensor is typically located near the catalytic converter in the exhaust system.
Q: Can I drive with a P2568 code?
A: While you can drive with this code, it's best to address it soon to maintain fuel efficiency and emissions standards.
Q: Does this code affect my car's performance?
A: It might not directly affect performance, but it can lead to increased emissions and reduced fuel efficiency.
