U2667 Lost Communication with the Steering Angle Sensor

The OBD2 code U2667 indicates a loss of communication with the steering angle sensor, which may affect the vehicle's stability control and steering response systems

Definition

The OBD2 code U2667 indicates a loss of communication with the steering angle sensor, which may affect the vehicle's stability control and steering response systems

Common causes

  • Faulty steering angle sensor
  • Damaged wiring or connectors
  • Poor electrical connections
  • Malfunctioning power supply to the sensor
  • Software issues or calibration errors
  • Faulty vehicle control module (VCM)
  • Interference from other electronic components

Common misdiagnoses

  • Faulty steering angle sensor
  • Wiring issues or damaged connectors
  • Faulty steering column control module
  • Issues with the vehicle's ABS module
  • Problems with the power steering system
  • Faulty body control module (BCM)
  • Incorrectly calibrated steering angle sensor
  • Software or firmware issues in the vehicle's control modules

Troubleshooting steps

  1. 1. Check for Additional Codes

    Use an OBD-II scanner to check for any other related trouble codes. This can provide more context and help identify if there are other issues affecting the steering angle sensor

  2. 2. Inspect Wiring and Connectors

    Visual Inspection: Check the wiring harness and connectors associated with the steering angle sensor for any signs of damage, corrosion, or loose connections

  3. 3. Connector Pins

    Ensure that the pins in the connectors are not bent, corroded, or pushed back

  4. 4. Test the Steering Angle Sensor

    Sensor Functionality: If possible, test the steering angle sensor using a multimeter or an oscilloscope to ensure it is functioning correctly

  5. 5. Calibration

    Some vehicles require the steering angle sensor to be calibrated after installation or repair. Check the vehicle’s service manual for calibration procedures

  6. 6. Check Power and Ground

    Verify that the steering angle sensor is receiving the correct voltage and ground. Use a multimeter to check for power at the sensor connector

  7. 7. Inspect the CAN Bus

    Since the steering angle sensor communicates over the CAN (Controller Area Network) bus, check for any issues with the CAN bus wiring or other modules on the bus

  8. 8. Look for shorts, opens, or high resistance in the CAN bus wiring

  9. 9. Check for Interference

    Ensure that there are no aftermarket devices or modifications that could be interfering with the communication between the steering angle sensor and the vehicle’s control modules

  10. 10. Clear Codes and Test Drive

    After performing any repairs or adjustments, clear the trouble codes using the OBD-II scanner and take the vehicle for a test drive to see if the code returns

  11. 11. Consult Technical Service Bulletins (TSBs)

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

  12. 12. Replace the Steering Angle Sensor

    If all other troubleshooting steps fail and the sensor is confirmed to be faulty, consider replacing the steering angle sensor

  13. 13. Professional Diagnosis

    If you are unable to resolve the issue, it may be best to consult a professional mechanic or dealership for further diagnosis and repair.Conclusion By following these steps, you can systematically troubleshoot the U2667 code and identify the root cause of the communication loss with the steering angle sensor. Always refer to the specific vehicle service manual for detailed procedures and specifications
