P2573 GMC Code - Direct Ozone Reduction Catalyst Deterioration Sensor Circuit Range/Performance
Quick Answer
The P2573 GMC code indicates a problem with the Direct Ozone Reduction Catalyst (DORC) deterioration sensor circuit, specifically in terms of range or performance. Common causes include Faulty DORC Sensor: The most common cause of the P2573 code is a malfunctioning DORC sensor, which may need to be replaced, Wiring Issues: Corrosion or damage to the wiring connecting the DORC sensor to the vehicle's engine control module can trigger this code, Catalytic Converter Failure: A failing catalytic converter can also cause the DORC sensor to detect issues with ozone reduction, leading to the P2573 code. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2573 GMC Description
The P2573 GMC code indicates a problem with the Direct Ozone Reduction Catalyst (DORC) deterioration sensor circuit, specifically in terms of range or performance. The DORC sensor is responsible for monitoring the efficiency of the catalyst in reducing harmful emissions, particularly ozone. When this sensor detects that the catalyst is not performing within the expected parameters, it triggers the P2573 code.
Common Causes of P2573 GMC
- Faulty DORC Sensor: The most common cause of the P2573 code is a malfunctioning DORC sensor, which may need to be replaced.
- Wiring Issues: Corrosion or damage to the wiring connecting the DORC sensor to the vehicle's engine control module can trigger this code.
- Catalytic Converter Failure: A failing catalytic converter can also cause the DORC sensor to detect issues with ozone reduction, leading to the P2573 code.
- Exhaust System Leaks: Leaks in the exhaust system can impact the efficiency of the DORC sensor and trigger this code.
Symptoms of P2573 GMC
- Check Engine Light: The most common symptom associated with the P2573 code is the illumination of the Check Engine Light on the vehicle's dashboard.
- Decreased Fuel Efficiency: A deteriorating DORC sensor can lead to decreased fuel efficiency, as the engine may not be operating at optimal levels.
- Rough Idle: The engine may experience rough idling or hesitation when accelerating due to the impact on fuel combustion.
- Failed Emissions Test: If the DORC sensor is not functioning properly, the vehicle may fail emissions tests due to increased pollutant emissions.
How to Fix P2573 GMC
- Diagnose the Issue: Use a diagnostic tool to read the code and determine the specific cause of the problem.
- Replace DORC Sensor: If the sensor is faulty, it will need to be replaced with a new one to restore proper functionality.
- Check Wiring: Inspect the wiring connecting the DORC sensor to the engine control module for any damage or corrosion, and repair as necessary.
- Repair Exhaust Leaks: Address any leaks in the exhaust system that could be impacting the efficiency of the DORC sensor.
- Clear Codes: Once the repairs have been made, clear the code from the vehicle's system and test to ensure the issue has been resolved.
Cost to Fix P2573 GMC
The cost of repairing a P2573 GMC code can vary depending on the specific cause of the issue and the labor rates at the auto repair shop. In general, the cost of replacing a DORC sensor can range from $150 to $300, while addressing wiring issues or exhaust system leaks may cost additional labor and parts.
