P2476 Chevrolet Code - Exhaust Gas Temperature Sensor Circuit High Bank 2 Sensor 4
Quick Answer
The P2476 code for Chevrolet vehicles indicates a problem with the exhaust gas temperature sensor circuit on Bank 2 Sensor 4. Common causes include Faulty Exhaust Gas Temperature Sensor: The sensor itself may be malfunctioning and providing incorrect readings to the ECM, Damaged Wiring or Connectors: Corrosion, fraying, or damage to the wiring or connectors in the sensor circuit can disrupt the signal transmission, ECM Malfunction: A problem with the engine control module can also trigger the P2476 code. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P2476 Chevrolet Description
The P2476 code for Chevrolet vehicles indicates a problem with the exhaust gas temperature sensor circuit on Bank 2 Sensor 4. This sensor is responsible for monitoring the exhaust gas temperature and providing crucial data to the engine control module (ECM) for optimal fuel delivery and emission control. When the sensor detects a high voltage signal, it triggers the P2476 code, indicating that the exhaust gas temperature is higher than expected.
Common Causes of P2476 Chevrolet
- Faulty Exhaust Gas Temperature Sensor: The sensor itself may be malfunctioning and providing incorrect readings to the ECM.
- Damaged Wiring or Connectors: Corrosion, fraying, or damage to the wiring or connectors in the sensor circuit can disrupt the signal transmission.
- ECM Malfunction: A problem with the engine control module can also trigger the P2476 code.
- Exhaust Leaks: Leaks in the exhaust system can affect the sensor's readings and trigger the code.
- Catalytic Converter Issues: A faulty catalytic converter can lead to high exhaust gas temperatures and trigger the code.
Symptoms of P2476 Chevrolet
- Check Engine Light: The most common symptom associated with the P2476 code is the illumination of the check engine light on the vehicle's dashboard.
- Reduced Fuel Efficiency: The vehicle may experience a decrease in fuel efficiency due to incorrect fuel delivery caused by the faulty exhaust gas temperature sensor.
- Engine Misfires: High exhaust gas temperatures can lead to engine misfires or rough idling.
- Increased Emissions: The vehicle may produce higher emissions than usual due to improper combustion caused by the sensor issue.
- Reduced Engine Performance: The engine may lack power or responsiveness, affecting the overall driving experience.
How to Fix P2476 Chevrolet
- Diagnose the Issue: Use a diagnostic scanner to retrieve the specific code and pinpoint the exact cause of the problem.
- Inspect Wiring and Connectors: Check the wiring and connectors in the exhaust gas temperature sensor circuit for any damage or corrosion. Repair or replace as needed.
- Replace Exhaust Gas Temperature Sensor: If the sensor is faulty, replace it with a new one following manufacturer guidelines.
- Clear Error Codes: After making the necessary repairs, clear the error codes and reset the ECM to see if the issue has been resolved.
- Test Drive: Take the vehicle for a test drive to ensure that the check engine light does not reappear and that the vehicle's performance has returned to normal.
Cost to Fix P2476 Chevrolet
The cost of repairing a P2476 code for a Chevrolet vehicle can vary depending on the specific cause of the issue. In general, the cost of replacing an exhaust gas temperature sensor can range from $100 to $300, including parts and labor. Additional costs may apply if wiring or connectors need to be replaced. Diagnostic time and labor rates at auto repair shops can vary, but on average, you can expect to pay between $80 and $150 per hour for labor.
