B2328 Column Reach Feedback Potentiometer Circuit Failure

The OBD2 code B2328 indicates a malfunction in the column reach feedback potentiometer circuit, which is responsible for detecting the position of the steering column adjustment mechanism

Definition

The OBD2 code B2328 indicates a malfunction in the column reach feedback potentiometer circuit, which is responsible for detecting the position of the steering column adjustment mechanism

Common causes

  • Faulty potentiometer
  • Wiring issues (shorts, opens, or corrosion)
  • Poor electrical connections
  • Malfunctioning steering column assembly
  • Software or calibration issues
  • Faulty body control module (BCM)

Common misdiagnoses

  • Faulty steering column
  • Defective power steering module
  • Malfunctioning body control module (BCM)
  • Wiring issues or shorts in the circuit
  • Bad ground connections
  • Incorrectly calibrated steering angle sensor
  • Faulty steering wheel position sensor
  • Issues with the electronic throttle control system

Troubleshooting steps

  1. 1. Check for Additional Codes

    Use an OBD-II scanner to check for any other related trouble codes. This can help identify if there are multiple issues that need to be addressed

  2. 2. Inspect Wiring and Connectors

  3. 3. Visually inspect the wiring and connectors associated with the feedback potentiometer. Look for signs of damage, corrosion, or loose connections

  4. 4. Ensure that all connectors are securely attached and free of dirt or moisture

  5. 5. Test the Potentiometer

  6. 6. Use a multimeter to test the resistance of the feedback potentiometer. Compare the readings to the specifications provided in the vehicle's service manual

  7. 7. If the resistance is outside the specified range, the potentiometer may be faulty and need replacement

  8. 8. Check for Short Circuits

  9. 9. Inspect the wiring harness for any signs of short circuits or grounding issues. A short circuit can cause incorrect readings and trigger the B2328 code

  10. 10. Inspect the Steering Column

  11. 11. Check the steering column for any mechanical issues that could affect the potentiometer's operation. Ensure that the column is not binding or obstructed

  12. 12. Test the Control Module

  13. 13. If the potentiometer and wiring are in good condition, the issue may lie with the vehicle's control module. Check for software updates or reprogramming needs

  14. 14. In some cases, the control module may need to be replaced if it is determined to be faulty

  15. 15. Clear the Code and Test Drive

  16. 16. After performing repairs or replacements, clear the trouble code using the OBD-II scanner

  17. 17. Take the vehicle for a test drive to see if the code returns. Monitor the performance of the steering column and any related systems

  18. 18. Consult Technical Service Bulletins (TSBs)

  19. 19. Check for any TSBs related to the B2328 code for your specific vehicle make and model. Manufacturers may have issued guidance on common issues and fixes

  20. 20. Seek Professional Help

  21. 21. If you are unable to resolve the issue after these steps, consider seeking assistance from a qualified mechanic or dealership. They may have specialized tools and knowledge to diagnose and repair the problem effectively. By following these troubleshooting steps, you should be able to identify and address the cause of the B2328 code
