What is C0813?

The DTC code C0813 indicates a problem with the Steering Angle Sensor, which is a critical component in vehicles equipped with electronic stability control (ESC) and advanced driver-assistance systems (ADAS). This code signifies that the sensor is either malfunctioning or providing incorrect data to the vehicle's control module. The steering angle sensor helps determine the driver's intended steering direction and assists in stabilizing the vehicle, especially during cornering. When this sensor fails, it can lead to issues such as loss of traction control, steering assist problems, and potentially unsafe driving conditions. Commonly found in vehicles like the 2014-2018 Chevrolet Silverado and GMC Sierra, a malfunctioning C0813 code may result in the illumination of the check engine light or stability control warning. If left unaddressed, this can lead to erratic vehicle behavior, making it crucial to diagnose and repair the issue promptly. Ignoring this code can not only affect the vehicle's performance but could also compromise safety features, leading to increased risks while driving. Understanding the implications of this code can help car owners make informed decisions regarding repairs and maintenance.

Symptoms

Common symptoms when C0813 is present:

  • The check engine light stays on, indicating a need for diagnostic attention.
  • Loss of steering control or unusual steering response, which can make driving difficult.
  • Stability control warning light illuminates, affecting the vehicle's traction assist systems.
  • Difficulty in calibrating the steering wheel, leading to potential misalignment.
  • Unexpected changes in vehicle handling, particularly during turns or slippery conditions.

Possible Causes

Most common causes of C0813 (ordered by frequency):

  1. Faulty steering angle sensor (60% likelihood) - Over time, the sensor can wear out or become damaged, leading to inaccurate readings.
  2. Wiring issues or poor connections (25% likelihood) - Damaged wiring or loose connections can interrupt the signal sent from the sensor.
  3. Software calibration errors (10% likelihood) - Sometimes, the vehicle's software may require reprogramming or updates to function correctly.
  4. Electrical issues within the steering column (3% likelihood) - Less common but can occur if there are short circuits or grounding problems.
  5. Mechanical failures in the steering system (2% likelihood) - Rarely, mechanical issues can affect sensor function.
