What is C0C09?

DTC C0C09 is a diagnostic trouble code that indicates a communication issue within the vehicle's control modules, specifically relating to the steering angle sensor. This code is often found in specific Ford and Chrysler models, such as the 2015-2018 Ford F-150 and the 2016-2019 Chrysler 300. When this code appears, it typically signifies that the steering angle sensor is either malfunctioning or not communicating properly with the vehicle's Electronic Control Unit (ECU). This can lead to various problems, such as issues with stability control systems and potentially affecting the vehicle's handling. Drivers might notice that their traction control light or stability control light remains illuminated on the dashboard, which can be concerning if you're unsure of what it means. Ignoring this code can lead to more significant issues down the line, including compromised vehicle safety and handling characteristics. Therefore, understanding and addressing the C0C09 code promptly is essential for maintaining your vehicle's performance and safety.

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

Symptoms

Common symptoms when C0C09 is present:

  • The check engine light or stability control light remains illuminated, indicating a potential issue with vehicle handling.
  • The steering feels unusually stiff or loose, which can affect driver control and safety.
  • You may experience unexpected traction control activation, leading to a loss of power when accelerating in slippery conditions.
  • Erratic behavior of the dashboard indicators, such as flickering lights or inconsistent readings.
  • Poor fuel economy may occur if the vehicle's systems are not functioning optimally due to this code.

Possible Causes

Most common causes of C0C09 (ordered by frequency):

  1. The most common cause of the C0C09 code is a faulty steering angle sensor, which has a likelihood of about 60%. This component may fail due to wear and tear or electrical issues.
  2. Another cause could be damaged wiring or connectors related to the steering angle sensor. These issues can often lead to intermittent connection problems.
  3. Software glitches in the vehicle's ECU can also trigger this code, particularly after a recent update or repair. Keeping the software updated is crucial for optimal performance.
  4. Less common causes include issues with the ABS module, which can affect communication between sensors and the ECU.
  5. In rare cases, a malfunctioning ECU itself may be the culprit, though this is quite uncommon.
