What is C0A83?

The diagnostic trouble code (DTC) C0A83 refers to a malfunction associated with the steering angle sensor. This sensor plays a crucial role in providing information about the angle and direction of the steering wheel to various vehicle systems, especially those related to stability control and advanced driver-assistance systems (ADAS). When the C0A83 code is triggered, it typically indicates that the steering angle sensor has detected an abnormal reading or is malfunctioning altogether. This can lead to problems such as loss of steering assist, erratic handling, and the illumination of the check engine light or other warning lights on the dashboard. In practical terms, if you experience this code, it is essential to address it promptly as it can compromise vehicle safety and driveability. Commonly found in models like the 2015-2018 Honda Civic, this code can also appear in other vehicles equipped with similar electronic steering systems. Ignoring this code can lead to more severe issues, including complete steering failure, so it's advisable to seek diagnostic services as soon as possible.

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

Symptoms

Common symptoms when C0A83 is present:

  • The check engine light or stability control warning light stays on continuously, alerting you to potential steering issues.
  • You may notice that the steering feels unresponsive or excessively loose, impacting your control over the vehicle.
  • There could be a noticeable change in handling, such as the car pulling to one side while driving straight.
  • During sharp turns, you might experience an unexpected resistance or jerking motion in the steering wheel.
  • In some cases, there may be a decrease in fuel efficiency, often linked to poor sensor readings affecting engine management.

Possible Causes

Most common causes of C0A83 (ordered by frequency):

  1. The most common cause of the C0A83 code is a faulty steering angle sensor, with a likelihood of about 60%. This can occur due to wear or damage over time.
  2. Another common issue may be misalignment of the steering column, which can lead to incorrect sensor readings. This is often caused by accidents or improper repairs.
  3. Electrical issues, such as damaged wiring or poor connections to the steering angle sensor, can also trigger this code. Regular inspection can help prevent these issues.
  4. Less common but serious causes include software glitches in the vehicle's control module, which may require a firmware update or replacement.
  5. A rare cause could be physical damage to the steering system itself, such as a broken steering shaft or housing, which needs immediate attention.
