What is C0D85?

The DTC C0D85 is a diagnostic trouble code that indicates a malfunction in the vehicle's steering angle sensor, primarily found in models like the 2015-2018 Ford F-150. This code signifies that the steering angle sensor is not transmitting the correct data to the vehicle’s onboard computer, which can affect the overall safety and handling of your car. When the sensor fails, it can lead to issues such as difficulty in steering, erratic handling, and a lack of stability control. This can be particularly concerning during adverse weather conditions or when making sharp turns. As a result, the vehicle may also trigger the traction control and stability control systems to malfunction, leading to additional safety concerns. It’s essential to address this issue promptly to ensure your vehicle remains safe and reliable on the road. Ignoring this code may not only lead to further complications but can also result in increased repair costs down the line. It’s advisable to consult a qualified technician or use a diagnostic tool like the GeekOBD APP to retrieve more information on the code's context and any additional codes that may accompany it.

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

Symptoms

Common symptoms when C0D85 is present:

  • Check engine light stays on constantly, indicating that the onboard computer has detected an issue.
  • Steering feels heavy or unresponsive, making it difficult to maneuver the vehicle, especially in tight spaces.
  • Erratic vehicle handling, where the car may veer unexpectedly, making it hard to maintain a straight path.
  • Traction control light may frequently illuminate, suggesting that the vehicle is struggling to maintain grip on the road.
  • Increased wear on tires due to improper alignment resulting from a faulty steering angle sensor.

Possible Causes

Most common causes of C0D85 (ordered by frequency):

  1. The most common cause of C0D85 is a faulty steering angle sensor, occurring in about 65% of cases. This sensor may fail due to wear and tear or exposure to moisture.
  2. Another common issue is damaged wiring or connectors related to the steering angle sensor, which can lead to intermittent signals. This can happen due to physical damage during maintenance or corrosion.
  3. Improper vehicle alignment can also trigger this code, as it can affect the sensor's ability to provide accurate data. Regular alignment checks can prevent this issue.
  4. Less commonly, a malfunctioning electronic control unit (ECU) might misinterpret sensor data, leading to the C0D85 code. This requires advanced diagnostic tools to confirm.
  5. A rare cause could be software glitches within the vehicle’s computer system, necessitating a software update or reprogramming to resolve.
