You can use the GeekOBD APP to scan for DTCs, check freeze frame data, and perform a component test on the steering angle sensor. Follow the app's guided steps to pinpoint the issue.
What vehicles are most commonly affected by C05D6?
The C05D6 code is frequently found in 2015-2020 Ford Focus models, but it can also appear in other vehicles equipped with electronic stability control systems.
How can I prevent C05D6 from happening again?
Regular maintenance checks of the steering system, ensuring proper calibration after repairs, and avoiding rough driving conditions can help prevent reoccurrence of the C05D6 code.
What is C05D6?
The DTC C05D6 indicates a problem with the steering angle sensor, a critical component that measures the steering wheel's position and sends this data to the vehicle's electronic control unit (ECU). This code is often seen in various Ford models, particularly the 2015-2020 Ford Focus. When the steering angle sensor malfunctions, it can lead to several issues, including difficulty in steering, misalignment of the steering system, and problems with the vehicle's stability control and traction control systems. Car owners may experience the 'Check Engine' light activating, and in some cases, the vehicle may enter a limp mode, limiting its performance and responsiveness. Ignoring this code can compromise the vehicle's handling and safety, leading to potential accidents. It's crucial for vehicle owners to address this code promptly, as neglecting it can result in further damage to the steering system or other related components. Fortunately, diagnosing and repairing the issue can often restore normal operation, ensuring both safety and performance.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C05D6 is present:
- The 'Check Engine' light remains illuminated, indicating a fault that needs attention.
- Steering feels loose or unresponsive, making it difficult to maintain control, especially during turns.
- The vehicle experiences traction control or stability control issues, leading to unexpected skidding or loss of grip.
- The steering wheel may appear misaligned, causing the vehicle to drift or pull to one side while driving.
- In some cases, the vehicle may enter a limp mode, limiting acceleration and speed.
Possible Causes
Most common causes of C05D6 (ordered by frequency):
- A faulty steering angle sensor is the most common cause, with a likelihood of around 70%. This can result from wear and tear or electrical failures.
- Wiring issues, including damaged connectors or shorts, account for about 20% of the cases. These can disrupt the signal sent from the sensor to the ECU.
- Calibration issues after component replacement or suspension work can lead to a C05D6 code. Regular checks are essential, especially after repairs.
- Less commonly, a malfunction in the vehicle's ECU can trigger this code, though this is rare and should be diagnosed with advanced diagnostic tools.
- A rare cause could be software glitches, particularly in newer models, which may require a software update from the dealership.
