This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is having trouble reading the temperature of a special part that helps reduce pollution from the car. It's like when a thermometer doesn't work right and you can't tell how hot or cold it is.
The P2567 code indicates an issue with the circuit that monitors the temperature of the direct ozone reduction catalyst, which is part of the vehicle's emission control system.
The direct ozone reduction catalyst is a component in the vehicle's exhaust system designed to reduce ozone emissions. The temperature sensor circuit associated with this component provides critical data to the engine control module (ECM) to ensure optimal operation and efficiency. A fault in this circuit can lead to improper emissions control and potential engine performance issues.
• Check Engine Light is on
• Decreased fuel efficiency
• Possible increased emissions
• Faulty temperature sensor
• Damaged wiring or connectors
• Malfunctioning ECM
ECM: Engine Control Module
Catalyst: A substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage.
• Test the temperature sensor for proper operation.
• Replace the faulty temperature sensor.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Screwdriver set

Moderate
• Toyota Prius
• Honda Civic Hybrid
• Ford Fusion Hybrid
• Regular maintenance checks
• Ensure proper connections and wiring
• Use high-quality fuel
Sensor Issue
• Get the issue diagnosed by a professional mechanic.
• Avoid driving long distances until the issue is resolved.
Check with your vehicle manufacturer for emissions-related warranty coverage.
This code has become more common as emission standards have tightened and more vehicles are equipped with advanced emission control systems.
Moderate – While the vehicle may still be drivable, it should be checked soon to avoid potential emissions violations and performance issues.
Driving with a malfunctioning emission control system 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 my car with a P2567 code?
A: It's possible to drive, but it's recommended to fix the issue soon to avoid increased emissions and potential engine performance problems.
Q: How can I prevent this code from appearing?
A: Regular maintenance and inspections can help prevent sensor and wiring issues that lead to this code.

Fitment Required · Vehicle-fitment part
Relevant when catalyst-efficiency or emissions faults persist after proper diagnosis.
Catalyst-efficiency faults sometimes point toward converter problems after proper testing.
Catalytic converters are highly vehicle-specific and should not be purchased by code alone.
View options on AmazonThese parts may be related to this fault category, but a code by itself does not confirm exact fitment or guarantee that replacing a part will solve the problem.
