To prevent future occurrences of the B0566 code, maintain your vehicle's steering system regularly. This includes checking for worn components, ensuring proper wheel alignment, and regularly inspecting wiring and connectors for damage.

What is B0566?

The Diagnostic Trouble Code (DTC) B0566 indicates a malfunction in the steering angle sensor system of your vehicle. This sensor plays a crucial role in providing data about the steering wheel's position to the vehicle's electronic control unit (ECU). An accurate steering angle reading is essential for various safety features, including stability control and anti-lock braking systems (ABS). When the B0566 code is triggered, it typically means that the sensor is either unable to communicate effectively with the ECU or is providing erroneous data. In real-world terms, this can lead to issues such as the vehicle's stability control system being disabled, an unstable steering feel, or even compromised braking efficiency in extreme cases. Common vehicles affected by this code include the 2010-2015 Chevrolet Equinox and the 2013-2016 Ford Fusion. Ignoring this code can lead to more significant safety concerns and potential repairs, so it's essential to address it promptly.

Symptoms

Common symptoms when B0566 is present:

  • The check engine light is illuminated on the dashboard, indicating a system fault.
  • Drivers may notice a strange feeling in the steering wheel, such as looseness or tightness, which can affect handling.
  • Unusual behavior in traction control or stability control systems, such as activation without cause or failure to activate when needed.
  • Increased difficulty in steering at lower speeds, suggesting that the steering assist may be compromised.
  • The vehicle may experience intermittent warning alerts or messages related to the steering system.

Possible Causes

Most common causes of B0566 (ordered by frequency):

  1. A faulty steering angle sensor is the most common cause, with a likelihood of about 70%. This can happen due to wear and tear or physical damage.
  2. Wiring issues, such as frayed or damaged wires, can lead to poor communication between the sensor and the ECU, accounting for roughly 15% of cases.
  3. A malfunctioning ECU could also be the culprit, though this is less common. It can happen due to software glitches or electrical shorts.
  4. An alignment issue can affect sensor readings, especially in vehicles with adjustable steering components; this is less common but should be considered.
  5. Rarely, a complete failure of the steering column assembly may trigger this code, leading to extensive and costly repairs.
