P247E Exhaust Gas Temperature Out of Range Bank 2 Sensor 3

The OBD2 code P247E indicates that the exhaust gas temperature (EGT) reading from Bank 2 Sensor 3 is outside the expected range, suggesting a potential issue with the sensor or the exhaust system

Definition

The OBD2 code P247E indicates that the exhaust gas temperature (EGT) reading from Bank 2 Sensor 3 is outside the expected range, suggesting a potential issue with the sensor or the exhaust system

Common causes

  • Faulty exhaust gas temperature sensor
  • Wiring issues or damaged connectors
  • Exhaust leaks
  • Engine control module (ECM) issues
  • Corroded or poor electrical connections
  • Incorrect sensor calibration
  • High exhaust temperatures due to engine performance issues

Common misdiagnoses

  • Faulty exhaust gas temperature sensor
  • Wiring issues or short circuits
  • Faulty engine control module (ECM)
  • Exhaust leaks
  • Incorrectly installed or damaged catalytic converter
  • Faulty turbocharger (if applicable)
  • Misdiagnosed fuel system issues
  • Ignition system problems
  • Air intake issues
  • Other sensor failures (e.g., oxygen sensors)

Troubleshooting steps

  1. 1. Check for Additional Codes

    Use an OBD-II scanner to check for any other trouble codes that may be present. This can help identify related issues

  2. 2. Inspect the Exhaust Gas Temperature Sensor

    Locate Bank 2, Sensor 3 (usually found in the exhaust system)

  3. 3. Check the sensor for physical damage, corrosion, or loose connections

  4. 4. Ensure that the sensor is properly mounted and not leaking exhaust gases

  5. 5. Test the Sensor

    Use a multimeter to test the resistance of the EGT sensor. Compare the readings to the manufacturer's specifications

  6. 6. If the sensor is a thermocouple type, you may need a specialized tool to test its output

  7. 7. Check Wiring and Connectors

    Inspect the wiring harness and connectors leading to the EGT sensor for any signs of wear, fraying, or damage

  8. 8. Look for any signs of short circuits or open circuits in the wiring

  9. 9. Examine the Exhaust System

    Check for any exhaust leaks upstream of the sensor, as this can affect the readings

  10. 10. Ensure that the exhaust system is not clogged or damaged, which could impact exhaust flow and temperature

  11. 11. Check Engine Coolant Temperature

    Ensure that the engine is reaching the proper operating temperature. A malfunctioning thermostat can affect exhaust temperatures

  12. 12. Inspect the Engine Control Module (ECM)

    In rare cases, the ECM may be faulty or have incorrect programming. Check for any software updates or reprogramming needs

  13. 13. Clear the Code and Test Drive

    After performing the checks and repairs, clear the trouble code using the OBD-II scanner

  14. 14. Take the vehicle for a test drive to see if the code returns. Monitor the EGT readings if possible

  15. 15. Consult Technical Service Bulletins (TSBs)

    Check for any TSBs related to the P247E code for your specific vehicle make and model. Manufacturers may have known issues and recommended fixes

  16. 16. Seek Professional Help

    If the issue persists after performing the above steps, consider consulting a professional mechanic or technician for further diagnosis. By following these steps, you should be able to identify and resolve the issue causing the P247E code
