What is C01FB?

DTC C01FB refers to a fault detected in the vehicle's chassis control module, particularly related to the steering angle sensor. This diagnostic trouble code often signifies that the steering angle sensor is malfunctioning or that there is an issue with the communication between the sensor and the module itself. Symptoms of this code can include an unresponsive power steering system, which can make vehicle handling difficult and potentially dangerous. The code may also trigger the 'Check Engine' light, prompting immediate attention. Owners of models like the 2015-2019 Ford F-150 may encounter this code more frequently due to the high-tech features integrated into these vehicles. Ignoring this code could lead to further complications, including loss of steering control, which poses significant safety risks. Therefore, addressing DTC C01FB promptly is essential for maintaining vehicle safety and performance.

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

Symptoms

Common symptoms when C01FB is present:

  • The 'Check Engine' light may illuminate on your dashboard, indicating a fault that needs attention.
  • You may experience difficulty while steering, making turns feel stiff or unresponsive during driving.
  • Fuel economy could decrease by up to 10-15% due to inefficient power steering operation.
  • A noticeable increase in steering effort, especially at lower speeds, may occur.
  • Unusual noises from the steering column might be heard when turning the steering wheel.

Possible Causes

Most common causes of C01FB (ordered by frequency):

  1. Faulty steering angle sensor (60% likelihood) - This is the most common cause, often due to wear and tear or electrical issues.
  2. Wiring issues (20% likelihood) - Damaged or corroded wiring can disrupt communication between the sensor and the control module.
  3. Calibration issues (10% likelihood) - Improper calibration after steering component replacement can trigger this code.
  4. Module failure (7% likelihood) - A malfunction in the chassis control module itself can lead to erroneous readings.
  5. Rare sensor compatibility issue (3% likelihood) - Using non-OEM parts may sometimes cause compatibility problems.
