Regular maintenance, such as checking power steering fluid levels, inspecting wiring for wear, and addressing any steering issues promptly, can help prevent the C05E3 code from reoccurring.

What is C05E3?

The C05E3 diagnostic trouble code signifies a problem with the vehicle's power steering control module. This code typically indicates that the module has detected an issue in the power steering system, which can lead to difficulty steering or the power steering not functioning at all. If you own a 2016-2020 Ford Explorer, you might encounter this code due to a malfunctioning sensor, wiring issues, or even a failing power steering pump. This code can lead to a serious safety risk if ignored, as steering becomes harder and may require significantly more effort to maneuver the vehicle. Drivers may also notice a more significant turning radius or hear unusual noises when turning the wheel. It's essential to address this issue promptly, as it can lead to further damage to the steering system, resulting in more costly repairs down the line. Regular inspections and using quality parts can help mitigate issues related to the C05E3 code. If you see this code, don’t just reset it; investigate the underlying issues to ensure safe vehicle operation.

Symptoms

Common symptoms when C05E3 is present:

  • Check engine light stays on constantly, indicating a persistent issue with the power steering system.
  • Difficulty in steering, with the steering wheel becoming hard to turn, especially at low speeds.
  • Unusual noises when turning the steering wheel, such as grinding or whining, which may signal a failing power steering pump.
  • Increased turning radius, making it challenging to navigate tight spaces.
  • Fluid leaks under the vehicle, specifically power steering fluid, indicating a potential failure in the system.

Possible Causes

Most common causes of C05E3 (ordered by frequency):

  1. The most common cause is a faulty power steering control module, with a high likelihood of about 60%. This module can fail due to electrical issues or wear over time.
  2. Wiring issues, such as damaged or corroded wires leading to the power steering module, are the second most common cause, accounting for approximately 25% of cases.
  3. A failing power steering pump can also trigger the C05E3 code, which can be prevented by regularly checking fluid levels and replacing worn components.
  4. Less common but serious causes include a malfunctioning steering rack, which may require extensive repairs if not addressed promptly.
  5. Rarely, issues with the vehicle's battery or electrical system can cause this code, affecting the power steering module's performance.
