What is C05C6?

DTC C05C6 is a diagnostic trouble code that indicates an issue with the steering system, specifically related to the electric power steering (EPS) module. When this code is triggered, it usually means that the EPS module has detected a fault that affects the steering assist function. In practical terms, this could result in your steering feeling heavier than usual or even a complete loss of power steering assist. If your vehicle is equipped with an EPS system, like many modern vehicles including the 2015-2020 Ford Explorer and other Ford models, you may experience symptoms that can compromise your vehicle's handling and safety. Ignoring this code can lead to more severe issues, such as permanent damage to the power steering system or even increased risk of an accident due to reduced steering control. Therefore, it's essential to address the C05C6 code promptly by diagnosing the underlying cause and performing necessary repairs. A qualified technician can use specialized tools to diagnose the EPS system and determine the exact cause of the problem, which may include checking for wiring issues, making sure that the EPS module is functioning correctly, and verifying that all related components are in good condition.

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

Symptoms

Common symptoms when C05C6 is present:

  • The check engine light illuminates, often accompanied by the power steering warning light.
  • Steering feels heavy or unresponsive, especially during low-speed maneuvers.
  • Sudden loss of power steering assist while driving, leading to difficulty in steering.
  • Increased effort required to turn the steering wheel, especially at parking speeds.
  • Unusual noises coming from the steering column during operation.

Possible Causes

Most common causes of C05C6 (ordered by frequency):

  1. The most common cause of the C05C6 code is a faulty electric power steering module, which has a likelihood of about 60%. This may occur due to wear and tear or electrical issues.
  2. Another frequent culprit is damaged wiring or poor connections in the EPS system, accounting for about 25% of cases. Corrosion or frayed wires can disrupt signals to the EPS module.
  3. A third potential cause is low power steering fluid level, which can occur if there are leaks in the system. This issue can be easily prevented by regular maintenance checks.
  4. Less common but serious causes include a malfunctioning steering angle sensor, which can lead to incorrect readings and erratic steering behavior.
  5. A rare cause could be a software glitch in the EPS system, which may require a firmware update to resolve.
