What is C01E3?

The C01E3 code is a manufacturer-specific trouble code primarily associated with Ford vehicles, including popular models like the Ford F-150 from 2015 to 2018. This code indicates a malfunction within the vehicle's stability control system, particularly pointing to issues with the steering angle sensor or its circuit. When this code appears, it means that the vehicle's computer has detected a problem that may affect traction control and overall vehicle stability. The steering angle sensor plays a crucial role in helping the vehicle understand its orientation in relation to the road and assists in functions like electronic stability control (ESC). If this sensor is malfunctioning or providing erroneous data, it can lead to reduced traction, especially in slippery conditions, and may cause the traction control light or check engine light to illuminate on your dashboard. Ignoring the C01E3 code could lead to further stability issues, increased wear on tires, and potential safety hazards while driving. Therefore, addressing this code promptly is essential for maintaining vehicle performance and safety.

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

Symptoms

Common symptoms when C01E3 is present:

  • The check engine light or traction control light is illuminated continuously, indicating a fault in the stability control system.
  • The steering feels unusually loose or stiff, which may cause discomfort during driving and can affect handling.
  • You may notice that the vehicle does not respond properly during acceleration or cornering, which can lead to potential safety risks.
  • Unexpected activation of the traction control system during normal driving conditions can be felt, leading to loss of vehicle control.
  • Increased tire wear can be observed over time due to improper alignment caused by a malfunctioning steering angle sensor.
