Regular maintenance of your vehicle's power steering system, including fluid checks and electrical inspections, can help prevent C01FA from recurring.

What is C01FA?

The diagnostic trouble code (DTC) C01FA indicates an issue with the power steering control module in various vehicles. This code typically appears when the module detects a malfunction within its system, which can lead to compromised steering responsiveness and safety hazards. When the power steering control module fails, drivers may experience difficulty in steering, especially at low speeds, resulting in a less maneuverable vehicle. This can become particularly problematic in tight parking situations or during sharp turns. Commonly affected vehicles include the 2015-2018 Ford Edge and the 2016-2019 GMC Terrain. In some cases, the vehicle may enter a 'limp mode' to protect the steering system, making it crucial for owners to address the issue promptly. Ignoring this code can lead to further damage not only to the power steering system but potentially to related components, increasing repair costs and risking driver safety. Understanding the root cause of the C01FA code and acting swiftly can save both time and money in the long run.

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

Symptoms

Common symptoms when C01FA is present:

  • The power steering warning light illuminates on the dashboard, signaling a potential issue with the steering system.
  • Drivers may notice increased difficulty in steering, particularly during low-speed maneuvers, making it hard to navigate tight corners or parking lots.
  • There may be a noticeable whining noise when turning the steering wheel, which can indicate low power steering fluid or a failing pump.
  • In some instances, the vehicle may enter a limp mode, limiting speed and steering capability to prevent further damage.
  • A decrease in fuel efficiency can occur if power steering components are straining, leading to more effort required for steering.

Possible Causes

Most common causes of C01FA (ordered by frequency):

  1. The most common cause is a failure in the power steering control module, which can occur due to electrical issues or software glitches, with a likelihood of around 60%.
  2. Another possibility is low power steering fluid levels, which can be caused by leaks in the system or insufficient maintenance practices.
  3. Electrical connection problems, such as corroded wires or loose connectors, can also lead to the C01FA code, making up about 20% of cases. Routine inspections can help prevent these issues.
  4. A less common but serious cause could be the failure of the power steering pump, which could require replacement if not addressed promptly.
  5. Rarely, issues with the vehicle's battery or charging system can cause the power steering control module to malfunction due to insufficient voltage.
