What is C0A61?

The diagnostic trouble code (DTC) C0A61 indicates a problem with the vehicle's steering angle sensor, specifically relating to its calibration or its connection to the vehicle's control module. This code is often seen in vehicles equipped with advanced driver-assistance systems (ADAS), such as lane departure warning or stability control features. When this code is triggered, it suggests that the steering angle sensor's data is inconsistent or has failed to calibrate correctly. In practical terms, this can lead to issues with the vehicle's handling, impacting safety and performance. Car owners may notice an unresponsive steering wheel or the vehicle may exhibit erratic behavior when cornering. If this issue is not addressed, it could lead to further complications with the vehicle's electronic stability control system, potentially increasing the risk of losing control while driving. Commonly found in models like the 2015-2018 Honda Accord, this code can also affect other makes and models with similar electronic steering systems. It's crucial to take this code seriously and seek a diagnostic assessment to ensure your driving experience remains safe and reliable.

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

Symptoms

Common symptoms when C0A61 is present:

  • Check engine light illuminates alongside the stability control warning light, indicating potential steering issues.
  • The steering wheel feels loose or unresponsive, making it difficult to control the vehicle accurately.
  • Erratic handling during turns, where the vehicle may drift or feel unstable, particularly at higher speeds.
  • Increased difficulty in engaging the lane-keeping assist feature, which may result in it failing to activate.
  • Unusual noises from the steering column when turning, which may indicate underlying mechanical issues.

Possible Causes

Most common causes of C0A61 (ordered by frequency):

  1. The most common cause of the C0A61 code is a faulty steering angle sensor, with a likelihood of approximately 60%. This sensor may fail due to wear and tear or electrical issues.
  2. Another potential cause is a misalignment of the steering wheel, which can occur after an accident or improper maintenance, leading to incorrect sensor readings.
  3. Corroded or damaged wiring harnesses that connect the sensor to the vehicle's control module can also trigger this code. Regular inspections can help prevent such issues.
  4. Less common but serious causes include a malfunctioning electronic control unit (ECU), which may require a reprogramming or replacement.
  5. A rare cause may involve software glitches in the vehicle’s ADAS systems, necessitating a software update to rectify the issue.
