What is C067A?

The Diagnostic Trouble Code (DTC) C067A indicates an issue with the Steering Angle Sensor (SAS) in various vehicles, particularly common in 2014-2019 Chevrolet and GMC models. This code signifies that the SAS, which plays a crucial role in vehicle stability control systems, has detected an inconsistency or malfunction. The sensor measures the angle of the steering wheel to help the vehicle's control systems adjust for steering input and maintain stability. If the SAS fails or sends incorrect data, it can lead to various real-world driving implications, including poor handling, increased tire wear, and compromised safety features, such as electronic stability control (ESC) and traction control. Drivers may notice that their steering feels off-center or that warning lights illuminate on the dashboard. Ignoring this code can lead to more significant issues over time, such as reduced maneuverability and potentially dangerous driving conditions, especially in adverse weather. Addressing the C067A code promptly can prevent further damage to the steering system and enhance your vehicle's overall performance and safety.

System: C - Chassis (ABS, Steering, Suspension)

Symptoms

Common symptoms when C067A is present:

  • Check engine light remains illuminated, indicating a persistent issue that requires attention.
  • Steering feels off-center or unresponsive, which may lead to difficulty in maintaining a straight line when driving.
  • Tire wear may increase due to the misalignment caused by incorrect steering angle readings.
  • Electronic stability control warnings may activate, compromising your vehicle's handling and safety features.
  • Inconsistent traction control performance, leading to potential skidding or loss of control during turns.

Possible Causes

Most common causes of C067A (ordered by frequency):

  1. Most common cause: A faulty steering angle sensor, occurring in approximately 60% of cases. This can be due to wear and tear or manufacturing defects, leading to incorrect readings.
  2. Second most common cause: Wiring issues, such as frayed or damaged wires, which can interfere with the sensor’s ability to send accurate data to the vehicle's computer.
  3. Third cause: Calibration problems after component replacement. If the SAS is not calibrated correctly, it can trigger the C067A code.
  4. Less common but serious cause: Steering column issues or damage, which may require extensive repairs or part replacements.
  5. Rare but possible cause: Software glitches in the vehicle’s control module that may misinterpret the SAS data.
