Regular maintenance of your power steering system can help prevent C0924 from recurring. This includes checking and cleaning electrical connections, inspecting for wire damage, and ensuring fluid levels are appropriate.

What is C0924?

DTC C0924 indicates that there is a calibration error with the torque sensor in the vehicle's power steering system. This code is commonly found in various General Motors vehicles, particularly models from the Chevy, GMC, and Buick brands manufactured between 2010 and 2018. The torque sensor plays a crucial role in determining how much assistance the power steering system should provide based on the driver's input. When the system detects an inconsistency or malfunction in the torque sensor readings, it triggers the C0924 trouble code. This can lead to several issues, including a heavy steering feel, especially at low speeds, and can affect overall vehicle handling. Ignoring this code may result in further damage to the steering components, increased wear on the system, and potential safety hazards. Therefore, understanding and addressing this code promptly is essential for maintaining the safety and functionality of your vehicle.

Symptoms

Common symptoms when C0924 is present:

  • Check engine light illuminated, indicating an issue with the power steering system.
  • Steering feels unusually heavy, especially during low-speed maneuvers, making it difficult to turn the wheel.
  • Unresponsive steering or delayed response when turning, which can lead to unsafe driving conditions.
  • Increased wear on tires due to improper alignment caused by steering issues.
  • Potential for grinding or unusual noises when turning the steering wheel, indicating possible mechanical issues.

Possible Causes

Most common causes of C0924 (ordered by frequency):

  1. {'cause': 'Faulty torque sensor - 40% likelihood. This is the most common cause and can occur due to wear or electrical issues.', 'details': 'The torque sensor may be damaged or malfunctioning, leading to inaccurate readings.'}
  2. {'cause': 'Wiring issues - 30% likelihood. Damaged or corroded wiring can disrupt the signal between the sensor and the power steering control module.', 'technicalExplanation': 'Wiring problems can include frayed wires, poor connections, or corrosion at connectors.'}
  3. {'cause': 'Power steering control module failure - 20% likelihood. The computer controlling the power steering may fail, leading to the error code.', 'preventionTips': 'Regularly inspect the steering system and ensure all connections are clean and secure.'}
  4. {'cause': 'Software glitch - 5% likelihood. Occasionally, a software issue can cause the system to misinterpret sensor data.', 'details': 'Updating the vehicle’s software may resolve this issue.'}
  5. {'cause': 'Mechanical failure - 5% likelihood. Issues in the steering mechanism itself may lead to improper torque readings.', 'details': 'This could include problems with the steering rack or pump.'}
