The engine control module has detected an electrical fault in the circuit of the Direct Ozone Reduction (DOR) catalyst temperature sensor. This sensor is critical for monitoring the thermal state of the catalyst to ensure emissions are properly reduced.
The sensor has developed an internal open or short circuit, preventing it from sending a valid signal.
Wires leading to the sensor are frayed, melted, or broken due to heat or mechanical wear.
Moisture or debris in the electrical connector has created high resistance or a complete loss of contact.
The sensor is not properly seated or was damaged during a previous service procedure.
The internal circuitry of the ECM is unable to process the sensor signal, though this is rare.
No, P2567 is specifically a circuit fault. While the catalyst may be failing, this code indicates an electrical issue with the sensor or its wiring.
It is highly unlikely. This code is almost always caused by the sensor or wiring; replacing the ECM without verifying the circuit is generally an incorrect and expensive approach.
The vehicle is usually drivable, but it will not pass emissions testing and may eventually enter a reduced power mode to protect the emissions system.
