What is C0F14?

The DTC code C0F14 is a diagnostic trouble code that primarily indicates a malfunction within the steering control system, specifically in vehicles like the 2015-2018 Honda Civic. This code generally relates to issues with the Electric Power Steering (EPS) system, which is designed to assist the driver in steering the vehicle with less effort. When this code is triggered, it often means that the EPS system is either not functioning correctly or is experiencing intermittent faults that may affect steering response. In practical terms, this could lead to a stiff or unresponsive steering wheel, making it difficult to maneuver the vehicle safely. The C0F14 code can also be linked to faults in the steering angle sensor or problems within the vehicle's onboard communication network, such as loose connections or damaged wiring. Such issues can impact overall vehicle performance, safety, and drivability. It's important for vehicle owners to address this code promptly, as ignoring it can lead to further complications, including complete loss of steering assistance and increased risk of accidents.

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

Symptoms

Common symptoms when C0F14 is present:

  • The check engine light remains illuminated, indicating a potential issue with the steering system.
  • Drivers may experience a stiff steering wheel, particularly at low speeds, making it difficult to maneuver the vehicle.
  • There could be a noticeable decrease in fuel efficiency, often by 10-15%, due to the increased effort required to steer.
  • Intermittent power steering assist may occur, where the steering feels normal at times but becomes heavy unexpectedly.
  • Unusual noises from the steering column or a grinding sound may be present when turning the steering wheel.

Possible Causes

Most common causes of C0F14 (ordered by frequency):

  1. The most common cause of the C0F14 code is a faulty steering angle sensor, which has a likelihood of about 40%. This sensor measures the angle of the steering wheel and sends this information to the vehicle's computer. If it's not functioning properly, it can trigger C0F14.
  2. Another frequent cause is wiring issues, such as damaged or corroded connections. This can disrupt communication between the EPS system and the vehicle's control module, accounting for roughly 30% of cases.
  3. A less common cause involves software glitches in the EPS control module. Regular updates and diagnostics can help prevent this issue.
  4. In some cases, the power steering pump may fail or develop leaks, leading to a lack of fluid pressure and triggering the C0F14 code.
  5. Rarely, issues with the vehicle's battery or alternator affecting the EPS system can also trigger this code, though this is less common.
