What is C05F6?
DTC C05F6 is a diagnostic trouble code that indicates a fault in the vehicle's chassis control system, particularly related to the steering angle sensor. This issue is most commonly found in various Ford models, including the 2015 to 2019 Ford F-150. When this code is triggered, it typically signifies that the steering angle sensor is not providing accurate information to the vehicle's control module. This can lead to problems with stability control, traction control, and other safety features. If the steering angle sensor malfunctions, the vehicle may display erratic behavior while driving, such as unresponsive steering or unexpected changes in handling. In severe cases, this could compromise the vehicle's safety systems, making it imperative to address this code promptly. Car owners may notice that the check engine light illuminates or that they experience unusual feedback from the steering wheel. Ignoring this code can lead to further complications, such as increased wear on steering components or complete failure of the steering system, resulting in costly repairs and potential risk while driving.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C05F6 is present:
- The check engine light remains illuminated, indicating a fault in the steering system.
- Drivers may experience a stiff steering wheel, making it difficult to control the vehicle effectively.
- Unusual noises can occur when turning the steering wheel, often described as grinding or clicking sounds.
- The vehicle may exhibit unintended lane changes or drift, signaling a lack of proper steering response.
