What is C0965?

DTC C0965 is a diagnostic trouble code that indicates an issue with the steering angle sensor or its related circuitry in your vehicle. This code is particularly prevalent in vehicles like the 2015-2018 Ford F-150, which rely heavily on electronic systems for steering and handling. When this code is triggered, it means that the vehicle's onboard computer has detected an anomaly in the steering angle signal, which can affect your steering stability and safety features such as traction control and electronic stability control. Ignoring this code can lead to more severe problems down the line, including difficulty steering and premature wear on your vehicle's components. It's crucial for car owners to understand that this code does not always present immediate symptoms, but over time, it can lead to significant handling issues and compromised safety. Fortunately, with proper diagnostics and repair, you can resolve the C0965 code effectively. This typically involves checking the wiring and connectors associated with the steering angle sensor and ensuring that the sensor itself is functioning correctly.

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

Symptoms

Common symptoms when C0965 is present:

  • The check engine light remains illuminated, indicating a potential issue with the vehicle's electronic systems.
  • You may notice an inconsistent steering response, where the vehicle feels unstable or difficult to steer during maneuvers.
  • Fuel economy can decrease by 10-15% as the vehicle struggles to maintain optimal driving conditions.
  • In some cases, the vehicle may exhibit erratic traction control behavior, engaging unexpectedly during normal driving.
  • You might experience a warning message on the dashboard related to steering or stability control, urging you to check the system.

Possible Causes

Most common causes of C0965 (ordered by frequency):

  1. The most common cause of the C0965 code is a faulty steering angle sensor, which has a likelihood of around 60%. This sensor measures the angle of the steering wheel and relays this data to the vehicle’s computer system.
  2. Another cause could be damaged wiring or loose connections in the steering column or associated harnesses, which can lead to incorrect readings. This issue is often responsible for about 25% of cases.
  3. Thirdly, it could be due to software issues in the vehicle's ECU. Keeping the software updated can help prevent this problem, especially in newer models.
  4. Less commonly, a failure in the vehicle's ABS system can also trigger this code. This would require a more in-depth inspection of the ABS module.
  5. Lastly, while rare, a malfunction in the vehicle's power steering pump can lead to the C0965 code being triggered due to changes in steering effort.
