What is C0F05?

The diagnostic trouble code (DTC) C0F05 indicates a problem with the vehicle's stability control system, particularly related to the steering angle sensor. This code is commonly seen in models like the 2016-2020 Ford F-150 and others equipped with advanced driver assistance systems (ADAS). When the C0F05 code is triggered, it suggests that the steering angle sensor is reporting incorrect data or is malfunctioning. This can lead to issues with vehicle stability, especially during turns or in adverse weather conditions. The sensor plays a crucial role in maintaining the vehicle's traction and stability by sending real-time data to the anti-lock braking system (ABS) and electronic stability control (ESC). If left unaddressed, this code can compromise vehicle safety, lead to erratic handling, and potentially result in an increase in tire wear. Moreover, the check engine light will likely illuminate, and you may experience reduced performance or responsiveness in steering. It’s important to address this code promptly to ensure safe driving conditions and avoid further complications that could lead to more costly repairs.

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

Symptoms

Common symptoms when C0F05 is present:

  • The check engine light stays on constantly, indicating a fault in the vehicle's stability system.
  • You may notice that the steering feels unresponsive or loose, particularly during quick maneuvers.
  • Drivers may experience unusual traction control activation, where the system engages unexpectedly.
  • In severe cases, the vehicle may display warning messages related to stability control on the dashboard.
  • Fuel efficiency may also decrease due to the vehicle's systems working harder to compensate for the fault.

Possible Causes

Most common causes of C0F05 (ordered by frequency):

  1. The most common cause of the C0F05 code is a faulty steering angle sensor, which has an approximately 70% likelihood of being the issue. This sensor may become misaligned or damaged due to wear and tear.
  2. A second common cause is damaged wiring or connectors related to the steering angle sensor. Corrosion or physical damage can lead to intermittent signals.
  3. In some cases, calibration issues can arise after suspension repairs or modifications, necessitating reprogramming of the sensor to the vehicle's specifications.
  4. Less commonly, the problem may stem from issues within the ABS module, which can affect the communication with the steering angle sensor.
  5. A rare but possible cause could be software glitches in the vehicle's control modules, which may require a software update.
