DOR Catalyst Temp Sensor

Diagnostic & Technical Explanation
Code P2567 (Direct Ozone Reduction Catalyst Temperature Sensor Circuit) sets when the ECM sees an open, shorted, out-of-range, or intermittent signal from the temperature sensor monitoring a direct ozone reduction (DOR) catalyst, a coated radiator/condenser surface used on some platforms to break down ground-level ozone from ambient air passing through the cooling package. Causes are a corroded connector exposed to road spray at the front of the vehicle, a failed thermistor element, or wiring chafed against the radiator support.

These 5 diagnostic trouble codes share one detection mechanism and one repair path, which is why MechanicDB groups them into a single authored fault family rather than repeating the same explanation 5 times.
