P247D Exhaust Gas Temperature Out of Range Bank 2 Sensor 2

The OBD2 code P247D indicates that the exhaust gas temperature (EGT) for Bank 2, Sensor 2 is outside the expected range, suggesting a potential issue with the sensor or the exhaust system

Definition

The OBD2 code P247D indicates that the exhaust gas temperature (EGT) for Bank 2, Sensor 2 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
  • Incorrect sensor calibration
  • High exhaust temperatures due to engine problems
  • Corrosion or contamination on the sensor or connectors

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 related trouble codes. Sometimes, multiple codes can provide more context for the issue

  2. 2. Inspect the Exhaust Gas Temperature Sensor

    Visual Inspection: Check the wiring and connectors for the EGT sensor on Bank 2. Look for signs of damage, corrosion, or loose connections

  3. 3. Sensor Condition

    If the sensor appears damaged or has been exposed to extreme conditions, it may need to be replaced

  4. 4. Test the EGT Sensor

    Resistance Check: Use a multimeter to measure the resistance of the EGT sensor. Compare the readings to the manufacturer’s specifications

  5. 5. Voltage Check

    With the engine running, check the voltage output of the sensor. It should fall within the specified range. If it’s out of range, the sensor may be faulty

  6. 6. Inspect Wiring and Connectors

    Check the wiring harness leading to the EGT sensor for any signs of wear, fraying, or short circuits

  7. 7. Ensure that all connectors are secure and free of corrosion

  8. 8. Check for Exhaust Leaks

    Inspect the exhaust system for any leaks that could affect the readings of the EGT sensor. Leaks can cause incorrect temperature readings

  9. 9. Examine the Engine Control Module (ECM)

    Ensure that the ECM is functioning properly. In rare cases, a faulty ECM can lead to incorrect sensor readings

  10. 10. Check for any software updates or recalls related to the ECM

  11. 11. Clear Codes and Test Drive

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

  12. 12. Take the vehicle for a test drive to see if the code reappears. Monitor the EGT readings if your scanner allows it

  13. 13. Consult Technical Service Bulletins (TSBs)

    Check for any TSBs related to the P247D code for your specific vehicle make and model. Manufacturers may have issued guidance on common issues and fixes

  14. 14. Professional Diagnosis

    If the issue persists after performing the above steps, consider seeking help from a professional mechanic. They may have specialized tools and knowledge to diagnose the problem more effectively.Conclusion By following these troubleshooting steps, you can systematically identify and address the cause of the P247D code. Always refer to your vehicle’s service manual for specific details and specifications related to your make and model
