What is C0B58?

The diagnostic trouble code (DTC) C0B58 indicates a malfunction in the vehicle's power steering control module. This code is particularly prevalent in Ford models, including the 2015 to 2020 Ford Explorer and F-Series trucks. When this code is triggered, it means that the power steering system is not functioning properly, which can lead to a number of issues. For car owners, this may manifest as difficulty steering, unusual noises while turning the wheel, or a sudden loss of power steering assistance. The power steering control module is responsible for interpreting signals from the steering wheel and adjusting the steering response accordingly. A fault in this module can lead to increased steering effort, making it more challenging to maneuver the vehicle, especially at low speeds or during parking maneuvers. Ignoring this code can potentially lead to greater steering issues, increased wear on the power steering components, and could pose safety risks while driving. Therefore, it is important to address DTC C0B58 promptly to ensure safe vehicle operation.

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

Symptoms

Common symptoms when C0B58 is present:

  • The check engine light remains illuminated, indicating a persistent issue that needs attention.
  • Drivers may experience increased steering effort, especially when making tight turns or during parking.
  • Unusual noises such as grinding or whining can be heard when turning the steering wheel, indicating potential issues with the power steering system.
  • There may be a noticeable delay or lack of response in the steering, making it difficult to control the vehicle.
  • In some cases, the steering may feel 'loose' or less responsive, leading to a lack of confidence in vehicle handling.

Possible Causes

Most common causes of C0B58 (ordered by frequency):

  1. The most common cause of DTC C0B58 is a faulty power steering control module, with a likelihood of around 60%. This can occur due to electrical failures or internal component malfunctions.
  2. Another possible cause is damaged wiring or connectors within the power steering system, which can lead to intermittent issues and are often due to wear and tear.
  3. A third cause could be low power steering fluid levels or contamination, which can affect the overall performance and longevity of the system. Regular maintenance checks can help prevent this.
  4. Less commonly, a failing steering rack may also trigger this code, as it directly impacts steering response and safety.
  5. In rare cases, issues with the vehicle’s onboard computer can falsely trigger this code, requiring advanced diagnostic tools to verify.
