What is C0461?

DTC C0461 is a diagnostic trouble code that indicates a problem with the steering angle sensor circuit in your vehicle. This code is primarily seen in various models, including the 2015-2020 Chevrolet Silverado and similar GMC models. The steering angle sensor is a critical component that helps the vehicle's electronic stability control and traction control systems to determine the direction of the wheels. When this sensor is malfunctioning, it can lead to issues such as stability control warning lights activating and potential difficulties in vehicle handling. In simpler terms, if your steering angle sensor is not communicating correctly with the vehicle's computer, it may affect your safety and driving experience. The sensor transmits the position of the steering wheel to the car’s computer, which uses this information to ensure the vehicle remains stable, especially during turns or in slippery conditions. If you see the C0461 code, it’s essential to diagnose and address the issue promptly to avoid further complications and ensure safe driving.

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

Symptoms

Common symptoms when C0461 is present:

  • The check engine light or stability control warning light stays illuminated, indicating a potential issue with stability systems.
  • You may experience erratic steering behavior, where the vehicle feels unstable or wanders while driving, especially during turns.
  • Fuel economy may decrease by 10-15% due to the vehicle's traction control system working overtime to compensate for sensor errors.
  • Difficulty in engaging or disengaging the traction control system, which may lead to unexpected vehicle behavior in adverse conditions.
  • In some cases, the vehicle may enter 'limp mode', reducing power and speed to prevent further damage.

Possible Causes

Most common causes of C0461 (ordered by frequency):

  1. The most common cause is a faulty steering angle sensor, occurring in about 60% of cases. This may be due to wear and tear or electrical failure.
  2. Another frequent cause is damaged wiring or poor connections in the steering angle sensor circuit, which can happen due to corrosion or physical damage, accounting for about 25% of issues.
  3. A less common cause involves software malfunctions within the vehicle's computer system, which can occur after updates or repairs; keeping the vehicle's software updated can help prevent this.
  4. In rare cases, issues with the vehicle's ABS module can lead to the C0461 code, which may require more extensive repairs and diagnostics.
  5. Lastly, a bad ground connection in the electrical system can lead to intermittent faults, although this is quite rare.
