Definition

The OBD2 code C0287 indicates a problem with the delivered torque circuit, which typically relates to issues in the vehicle's traction control or stability control systems, affecting how torque is managed and delivered to the wheels

Common causes

  • Faulty torque sensor
  • Wiring issues (shorts, opens, or corrosion)
  • Poor connections or damaged connectors
  • Malfunctioning powertrain control module (PCM)
  • Issues with the transmission control module (TCM)
  • Faulty throttle position sensor
  • Problems with the engine control module (ECM)
  • Software glitches or outdated firmware

Common misdiagnoses

  • Faulty throttle position sensor
  • Malfunctioning accelerator pedal position sensor
  • Transmission issues
  • Engine control module (ECM) failure
  • Wiring or connector problems
  • Incorrectly calibrated or faulty cruise control system
  • Powertrain control module (PCM) issues
  • Sensor ground problems

Troubleshooting steps

  1. 1. Check for Additional Codes

    Use an OBD-II scanner to check for any other trouble codes that may be present. Addressing any additional codes can help narrow down the issue

  2. 2. Inspect Wiring and Connectors

    Visually inspect the wiring and connectors related to the delivered torque circuit. Look for signs of damage, corrosion, or loose connections

  3. 3. Pay special attention to the connectors on the ECM and TCM

  4. 4. Check for Ground Issues

    Ensure that all ground connections related to the ECM and TCM are secure and free of corrosion. Poor grounding can lead to communication issues

  5. 5. Test the Delivered Torque Circuit

    Use a multimeter to test the voltage and resistance in the delivered torque circuit. Compare the readings to the specifications in the vehicle's service manual

  6. 6. Inspect the Traction Control Module (TCM)

    If applicable, check the TCM for any signs of failure. This may involve testing the module or replacing it if necessary

  7. 7. Check the ECM

    If the TCM appears to be functioning correctly, the issue may lie with the ECM. Check for software updates or reprogramming if necessary

  8. 8. Look for Mechanical Issues

    Inspect the vehicle's drivetrain and related components for any mechanical issues that could affect torque delivery, such as a slipping transmission or differential problems

  9. 9. Clear Codes and Test Drive

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

  10. 10. Consult Technical Service Bulletins (TSBs)

    Check for any TSBs related to the C0287 code for your specific vehicle make and model. Manufacturers may have issued guidance on common issues and fixes

  11. 11. Seek Professional Help

    If the issue persists after performing these steps, it may be necessary to consult a professional mechanic or technician who has experience with your vehicle's systems.Conclusion Troubleshooting OBD-II codes can be complex, and the steps above are a general guide. Always refer to the specific service manual for your vehicle for detailed procedures and specifications
