NiskiHigh Signal in the Direct Ozone Reduction Catalyst Degradation Sensor Circuit. The engine control module detected voltage exceeding the norm in the sensor circuit monitoring the active ozone reduction catalyst condition.
OBD-II (EN): Ozone Reduction Catalyst Degradation Sensor Circuit High (Direct ORC)
Code P2575 indicates too high voltage in the circuit of the sensor monitoring the wear of the active ozone reduction catalyst (Direct ORC). This could be caused by a faulty sensor, a problem with the electrical wiring, or wear of the catalyst itself. Diagnosis by a qualified mechanic using an OBD-II scanner and multimeter is recommended.
Symptoms
MIL (Check Engine) light is on; no noticeable driving problems; possible slight deterioration in exhaust emission indicators; in some vehicles, deactivation of the active ozone reduction system.
Possible causes
• Faulty or contaminated ORC catalyst degradation sensor • Open or short circuit in the ORC sensor wiring harness • Oxidized or damaged sensor electrical connector • Worn or damaged ozone reduction catalyst (Direct ORC) • Control module (PCM/ECM) fault – less common
