What vehicles are most commonly affected by C07C2?

The C07C2 code is frequently reported in 2015-2020 Ford Fusion, Escape, and Lincoln MKC models. Keep an eye out for any manufacturer recalls or Technical Service Bulletins (TSBs) related to power steering issues.

How can I prevent C07C2 from happening again?

Regular maintenance of your vehicle's electrical system, including checking the battery and connections, can help prevent the C07C2 code. Additionally, periodic inspections of the power steering fluid and system can help catch issues before they lead to a fault code.

What is C07C2?

The diagnostic trouble code (DTC) C07C2 is associated with the vehicle’s power steering system, specifically indicating a fault within the electronic power steering (EPS) control module. When you see this code, it typically means that the power steering system isn’t functioning as intended, which can lead to a heavier steering feel, especially at low speeds. This issue can occur in various Ford and Lincoln models produced from 2015 to 2020. The EPS system relies on electronic sensors and motors, making it more sensitive to electrical issues, such as voltage drops or wiring problems. Ignoring this code can result in increased difficulty steering your vehicle, especially during maneuvers like parking, which could pose safety risks. In some cases, drivers may experience intermittent problems where the EPS system works sporadically. Therefore, addressing the C07C2 code promptly is crucial for maintaining your vehicle's drivability and safety. With the right diagnostic tools, like the GeekOBD APP, you can gather necessary data to pinpoint the exact issue, leading to more effective repairs and ensuring your vehicle remains safe to drive.

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

Symptoms

Common symptoms when C07C2 is present:

  • The steering wheel feels heavier than usual, especially during low-speed maneuvers, indicating potential power steering failure.
  • The check engine light or power steering warning light may remain illuminated on the dashboard, alerting you to the issue.
  • Drivers may notice a sudden loss of power steering assist while driving, leading to difficulty in steering.
  • Unusual noises, such as grinding or whining sounds, may occur when turning the steering wheel, suggesting a problem within the EPS system.
  • Intermittent steering assist may happen, where the power steering works at times and fails at others, creating unpredictability.

Possible Causes

Most common causes of C07C2 (ordered by frequency):

  1. The most common cause of DTC C07C2 is a faulty EPS control module, which accounts for about 60% of cases. This may involve issues with its internal circuitry or software malfunctions.
  2. Another likely cause is a wiring issue, such as damaged or corroded connectors, which can disrupt the power supply to the EPS system.
  3. A third cause could be low power steering fluid levels or contamination, which can affect the operation of the power steering system. Regular fluid checks can prevent this.
  4. Less commonly, a malfunctioning steering angle sensor may trigger this code, affecting the EPS module's ability to provide proper steering assistance.
  5. In rare cases, a failing vehicle battery or alternator can lead to insufficient power for the EPS system, triggering the C07C2 code.
