What vehicles are most commonly affected by C063B?

This code frequently affects vehicles like the Chevrolet Silverado (2015-2019) and GMC Sierra (2015-2019). Be aware of any recalls or service bulletins related to steering issues.

How can I prevent C063B from happening again?

Regular vehicle maintenance, including checking wiring connections and ensuring proper calibration after steering repairs, can help prevent C063B from recurring.

What is C063B?

The diagnostic trouble code (DTC) C063B refers to a malfunction in the steering angle sensor circuit, typically found in vehicles like the 2015-2019 Chevrolet Silverado. This code indicates that the vehicle's stability control system has detected an issue with the input from the steering angle sensor, which is crucial for functions like electronic stability control (ESC) and traction control. When the steering angle sensor is not functioning correctly, it can lead to a host of problems such as inconsistent steering feel, issues with traction control, and even the potential for reduced vehicle stability during maneuvers. For car owners, this means not only experiencing a less responsive steering feel but also facing safety concerns, especially in adverse driving conditions. Addressing this code promptly is essential, as ignoring it can lead to more significant issues down the road, including premature wear on other steering components and potential safety risks for drivers and passengers alike.

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

Symptoms

Common symptoms when C063B is present:

  • The check engine light or stability control warning light illuminates on the dashboard, indicating a fault.
  • The steering feels loose or unresponsive, making it difficult to control the vehicle, especially during turns.
  • Traction control may engage unexpectedly, causing the vehicle to feel like it is slipping or losing grip, particularly in wet or slippery conditions.
  • The steering angle sensor may produce erratic readings, leading to inconsistent steering behavior while driving.
  • In some cases, the vehicle may experience a reduction in fuel efficiency due to the additional strain on the engine management systems.

Possible Causes

Most common causes of C063B (ordered by frequency):

  1. The most common cause is a faulty steering angle sensor, which has a likelihood of around 60%. Issues can arise from wear and tear or electrical failures.
  2. Another common cause is damaged wiring or connectors in the steering system, which can disrupt the sensor's signals. This can occur from physical damage or corrosion over time.
  3. A third cause could be calibration issues after a steering component replacement, leading to improper sensor readings. Regular maintenance and recalibration can help prevent this.
  4. Less common but serious causes include a malfunctioning electronic control unit (ECU) that processes sensor data, which can affect multiple systems in the vehicle.
  5. A rare cause might be software glitches in the vehicle's control modules, requiring a software update or reprogramming to resolve.
