What is C058A?

The diagnostic trouble code (DTC) C058A is specific to certain General Motors (GM) vehicles and indicates a problem related to the steering angle sensor. This sensor plays a critical role in determining the angle of the steering wheel, which is essential for proper vehicle handling and stability control. When the C058A code is triggered, it typically means that the steering angle sensor is either malfunctioning or has lost communication with the vehicle's electronic control module (ECM). Common vehicles affected include the 2014-2019 Chevrolet Silverado, 2015-2018 GMC Sierra, and various Cadillac models. The implications of this code can be significant; it may lead to the activation of the traction control and stability control systems, resulting in decreased vehicle safety and handling. Drivers may notice issues such as the check engine light illuminating, erratic steering behavior, or even the inability to engage certain safety features. If left unresolved, this issue can lead to further complications, including potential accidents due to compromised steering control. Therefore, understanding the C058A code and addressing it promptly is crucial for maintaining safe vehicle operation.

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

Symptoms

Common symptoms when C058A is present:

  • Check engine light stays on constantly, indicating a persistent issue that requires immediate attention.
  • Steering feels unresponsive or loose, making it difficult to control the vehicle accurately, especially during turns.
  • Erratic traction control or stability control activation, where the systems engage unexpectedly, compromising vehicle safety.
  • Inconsistent steering wheel position warning displayed on the dashboard, signaling that the steering angle sensor is reading incorrectly.
  • Difficulty in engaging cruise control, as the system may rely on accurate steering inputs to function effectively.

Possible Causes

Most common causes of C058A (ordered by frequency):

  1. The most common cause is a faulty steering angle sensor, which occurs in about 60% of cases. This can be due to wear and tear or internal failure.
  2. Another potential cause is wiring issues or poor connections, which might account for 25% of cases. Corrosion or frayed wires can disrupt communication with the ECM.
  3. Calibration issues after repair or replacement of the steering column can lead to a misreading, making up about 10% of cases. Proper calibration is essential for accurate sensor operation.
  4. Less common but serious cause could be a malfunctioning ECM, which can disrupt various systems, leading to a significant safety risk.
  5. A rare cause may include software glitches in the vehicle’s control systems that could require a software update to resolve.
