If the circuit is compromised, the sensor may provide incorrect temperature readings, affecting the emissions control process.

Step-by-step diagnostic guide

Action	Description	Tools Needed
Check for Other Related Codes	Use an OBD-II scanner to determine if there are other related fault codes that might provide further insight into the overall emissions system condition.	OBD-II Scanner
Inspect the Catalyst Temperature Sensor Circuit	Visually inspect the wiring and connections of the catalyst temperature sensor. Look for broken wires, loose connectors, corrosion, or other damage that could interfere with signal transmission.	Flashlight, Safety Gloves
Test the Direct Ozone Reduction Catalyst Temperature Sensor	Use a multimeter to measure the resistance or voltage output from the temperature sensor. Compare these values with the manufacturer’s specifications to determine if the sensor is functioning correctly.	Multimeter, Diagnostic Tool
Check Wiring and Connectors	Inspect all wiring and connectors that lead to and from the catalyst temperature sensor. Loose or corroded connectors can cause incorrect readings and signal loss. Repair any worn or broken wires and replace corroded connectors.	Flashlight, Multimeter
Repair or Replace Faulty Wiring/Connectors	If you find any damage in the wiring or connectors, repair or replace them to restore proper functionality of the circuit. Secure all connections properly to prevent future signal issues.	Basic Tools, Replacement Parts
Replace Faulty Catalyst Temperature Sensor	If the sensor is found to be faulty after testing, replace it with a new component. Make sure the new sensor is compatible with the system and is properly calibrated.	Replacement Catalyst Temperature Sensor
Clear the Code and Test Drive	After repairs, use an OBD-II scanner to clear the code. Take the vehicle for a test drive and ensure the emissions system operates smoothly without triggering the fault code again.	OBD-II Scanner, Vehicle Owner’s Manual
Recheck for Codes	Re-scan the vehicle after the test drive to verify that the P2567 code has been resolved. If the code persists, further diagnostics may be needed to identify other potential issues.	OBD-II Scanner
