What Does the P2571 Code Mean?
The P2571 code refers to a malfunction within the Direct Ozone Reduction Catalyst Temperature Sensor Circuit. This code indicates an issue related to the Environmental Air Catalyst Sensor (EAC), which is connected to the radiator of certain Super Low Emissions Vehicles (SULEV). This sensor plays a critical role in reducing smog and maintaining vehicle emissions standards.
What Causes the P2571 Code?
- EAC sensor failure (part of radiator assembly)
- Improper coding of the EAC sensor to the powertrain control module (DME)
- Radiator not meeting manufacturer specifications
What Are the Symptoms of the P2571 Code?
Common symptoms associated with the P2571 code may include:
- Check Engine Light illuminated
- Decreased engine performance
- Increased emissions
How Serious Is the P2571 Code?
The P2571 code is categorized as urgent. Immediate action is necessary to prevent potential severe damage to the vehicle or risk to driver and passengers. Ignoring this code could lead to further complications within the vehicle’s emission control systems.
How to Diagnose the P2571 Code
To accurately diagnose the P2571 code, a mechanic should:
- Use an OBD-II scanner to retrieve the code and any related codes.
- Inspect the EAC sensor and its connections for any visible damage or corrosion.
- Check the coding of the EAC sensor to ensure it is correctly programmed to the powertrain control module (DME).
- Examine the radiator for compliance with manufacturer specifications.
Common Repairs for the P2571 Code
- Replace the EAC sensor if it is found to be faulty.
- Recode the EAC sensor to the PCM if it has been improperly configured.
- Install a new OE radiator if the existing one does not meet specifications.
How Much Does It Cost to Fix the P2571 Code?
Repair costs for the P2571 code can vary widely based on the specific issue:
- Replacing the EAC sensor typically costs between $100 and $300.
- Recoding the sensor may range from $50 to $150.
- Replacing the radiator can cost anywhere from $500 to $1,500, depending on the vehicle make and model.
Can I Fix the P2571 Code Myself?
While some individuals with automotive knowledge may attempt to fix the P2571 code themselves, it is recommended to seek professional assistance. Proper diagnosis and repair require specialized tools and technical expertise, particularly for coding procedures and ensuring compliance with emission standards.
