What is C05CD?

The Diagnostic Trouble Code (DTC) C05CD refers to a specific malfunction within the vehicle's electrical system, particularly related to the control of the power steering assist system. This code indicates that the power steering control module has detected a fault in the steering assist circuitry. When this code appears, it often signifies that the vehicle may experience diminished steering assistance, leading to a heavier steering feel, especially at lower speeds. In some cases, the power steering may fail entirely, resulting in increased effort needed to turn the steering wheel, which can be unsafe and challenging for the driver, particularly in emergency situations. This code is particularly common in models like the 2015-2020 Ford Explorer, where drivers may notice the power steering warning light illuminating on the dashboard. Ignoring a C05CD code can lead to further complications, including potential damage to the steering assembly or additional electrical issues within the vehicle. It’s crucial to address this code promptly to ensure safe operation and prevent costly repairs down the line.

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

Symptoms

Common symptoms when C05CD is present:

  • The power steering warning light is illuminated on the dashboard, indicating a problem with the steering assist system.
  • Drivers may experience a heavy steering feel, especially when turning at low speeds, making maneuvering difficult.
  • Unresponsive steering assist, where the steering wheel does not return to center easily after turns, leading to a feeling of instability.
  • Increased effort required to turn the steering wheel, which can lead to driver fatigue on longer trips.
  • Intermittent loss of power steering, where the assist may work at times but fail unexpectedly during driving.

Possible Causes

Most common causes of C05CD (ordered by frequency):

  1. The most common cause of a C05CD code is a faulty power steering control module, which can occur in about 40% of cases. This module may fail due to electrical shorts or internal defects.
  2. Wiring issues such as damaged or corroded connectors in the power steering system can also trigger this code, accounting for approximately 30% of cases. Inspecting the wiring for any visible damage is crucial.
  3. A malfunctioning steering angle sensor can lead to incorrect readings and activate the C05CD code. Keeping this sensor calibrated can prevent issues and is responsible for about 20% of occurrences.
  4. Less common but serious causes include a failing power steering pump, which may lead to a complete loss of steering assist if not addressed.
  5. Rarely, software glitches in the vehicle’s control modules can also cause a C05CD code, though this is less than 10% of cases.
