Can I drive my car with C064C or should I stop immediately?

While it might be possible to drive with the C064C code, doing so can pose a significant safety risk. The vehicle's stability and traction control systems may not function correctly, especially in adverse conditions. It's advisable to address this issue as soon as possible to ensure safe driving.

How can I diagnose C064C myself using GeekOBD APP?

To diagnose C064C using the GeekOBD APP, start by connecting the app to your vehicle's OBD2 port. Use the app to scan for all trouble codes, paying close attention to C064C. Check the freeze frame data for additional context about the conditions when the code was triggered. This can guide you on whether to inspect the steering angle sensor directly.

What vehicles are most commonly affected by C064C?

C064C is frequently found in various models from General Motors, particularly in the Chevrolet Silverado and GMC Sierra from 2014 to 2019, among others. If you own one of these vehicles, it's essential to be aware of this code and its implications.

How can I prevent C064C from happening again?

To prevent C064C from reoccurring, ensure regular maintenance of your vehicle's electrical systems. Keep an eye on the condition of the steering angle sensor and related wiring, and avoid driving through deep water that could damage these components. Regular inspections can help catch issues before they trigger a diagnostic code.

What is C064C?

Diagnostic Trouble Code (DTC) C064C indicates a problem related to the vehicle's steering angle sensor or the communication between the steering angle sensor and the vehicle's control module. This code is commonly found in various models from General Motors, especially in trucks like the Chevrolet Silverado from 2014 to 2019. When the C064C code is triggered, it typically means that the steering angle sensor is not providing accurate information, potentially leading to issues with the vehicle's stability control and traction control systems. In practical terms, this can manifest as difficulty in steering, irregular handling, or warning lights illuminating on the dashboard. Ignoring this code can lead to further complications, including compromised safety features and increased wear on your vehicle's steering system. Addressing the issue promptly is crucial for maintaining optimal vehicle performance and safety.

Symptoms

Common symptoms when C064C is present:

  • Check engine light stays on constantly, indicating an underlying issue with the steering system.
  • Steering feels unresponsive or loose, making it difficult to maintain control of the vehicle during turns.
  • Traction control light may illuminate, suggesting that the vehicle's stability management system is compromised.
  • Increased tire wear due to improper alignment caused by inaccurate steering angle readings.
  • Unexpected changes in steering feedback, such as sudden stiffness or looseness when turning.

Possible Causes

Most common causes of C064C (ordered by frequency):

  1. Faulty steering angle sensor (60% likelihood) - The sensor may fail due to wear and tear, leading to inaccurate readings.
  2. Wiring issues or loose connections (20% likelihood) - Damaged wiring or poor connections can result in intermittent signals to the control module.
  3. Calibration issues (10% likelihood) - The steering angle sensor may need recalibration after repairs or part replacements.
  4. Malfunctioning control module (5% likelihood) - Rarely, the issue could stem from the control module itself, requiring replacement.
  5. Environmental factors (5% likelihood) - Water intrusion or dirt can affect sensor performance in some cases.
