What is C0516?

DTC C0516 refers to a fault in the Steering Angle Sensor Circuit, primarily affecting vehicles like the 2013-2018 Chevrolet Silverado and GMC Sierra. This code indicates that the vehicle's computer has detected an issue with the steering angle sensor, which is crucial for various stability control and safety systems, including traction control and electronic stability control. When this sensor fails or sends incorrect readings, it can lead to a loss of control, especially during adverse weather conditions or rapid maneuvers. Drivers may experience symptoms like the 'service stability system' warning light or reduced power steering assistance. Ignoring this code can result in increased wear on steering components and potential safety risks while driving. Therefore, addressing DTC C0516 promptly is essential for maintaining vehicle safety and performance. If the sensor is malfunctioning, it can prevent the vehicle from properly engaging safety features designed to keep it stable on the road. In summary, understanding the implications of DTC C0516 is vital for ensuring the reliability and safety of your vehicle's steering system.

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

Symptoms

Common symptoms when C0516 is present:

  • The 'Check Engine' light or 'Service Stability System' warning illuminates on the dashboard, indicating a problem with the steering system.
  • The vehicle may exhibit difficulty in steering, particularly during sharp turns or sudden maneuvers, leading to a lack of responsiveness.
  • Drivers may notice a significant decrease in fuel economy due to inefficient operation of the steering system, which can affect overall vehicle performance.
  • The steering wheel may feel unusually heavy or loose, making it challenging to maintain control at higher speeds.
  • In some cases, the vehicle's traction control system may deactivate, resulting in reduced stability on slippery surfaces.

Possible Causes

Most common causes of C0516 (ordered by frequency):

  1. The most common cause of DTC C0516 is a faulty steering angle sensor, accounting for approximately 70% of cases. This sensor can wear out over time or become uncalibrated.
  2. Another frequent cause is damaged wiring or connectors within the steering angle sensor circuit, which can disrupt the signal and lead to erroneous readings.
  3. Incorrect installation of the steering angle sensor during maintenance or repairs can also trigger this code. It's crucial to ensure proper alignment and calibration after any steering repairs.
  4. Less commonly, a malfunctioning electronic control unit (ECU) related to the steering system can cause DTC C0516. This is a serious issue requiring professional diagnosis.
  5. In rare situations, software glitches in the vehicle's onboard computer can lead to false readings from the steering angle sensor, necessitating a software update or reset.
