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.
