What is C0C56?

The DTC C0C56 code refers to a problem within the vehicle's steering angle sensor circuit. This code is particularly relevant for owners of various Ford models, including the 2015-2020 Ford F-150. When the vehicle's onboard diagnostic system detects a fault in the steering angle sensor or its circuit, it triggers the C0C56 code. This sensor is critical for ensuring that the vehicle's stability control and traction control systems function properly. If you experience issues like the check engine light illuminating, it indicates that the vehicle's computer has detected an anomaly in the sensor readings. A malfunctioning steering angle sensor can lead to compromised handling, affecting the driver’s ability to control the vehicle, especially in slippery conditions. Therefore, understanding this code is essential for maintaining vehicle safety and performance. Ignoring the C0C56 code can lead to further complications, including increased wear on steering components and potential failure of the stability control system, which may put the driver and passengers at risk. Regular diagnostics, especially if you notice symptoms associated with this code, can help prevent more extensive repairs down the line.

Symptoms

Common symptoms when C0C56 is present:

  • The check engine light stays illuminated, indicating a fault in the steering angle sensor system.
  • Driver experiences difficulty in steering, especially during turns or in slippery conditions, which can feel like the steering is unresponsive.
  • Fuel economy may decrease by approximately 5-10% as the vehicle stability control system may work overtime to compensate for the faulty sensor.
  • Unusual noises or vibrations may be felt through the steering wheel during normal driving conditions, indicating a potential issue with the steering system.
  • The vehicle may exhibit erratic behavior during cornering, where it does not track straight or feels unstable.

Possible Causes

Most common causes of C0C56 (ordered by frequency):

  1. The most common cause is a faulty steering angle sensor, which accounts for about 60% of cases. This can occur due to wear and tear or exposure to moisture.
  2. A second possible cause could be damaged wiring or connectors in the steering angle sensor circuit, which may lead to poor connections. This can happen if the vehicle has been in an accident or experienced corrosion.
  3. Another cause is incorrect sensor calibration after replacement or a repair, which can affect the sensor's readings and lead to code C0C56.
  4. A less common but serious cause might be a malfunction in the vehicle's electronic stability control module, which can cause the steering angle sensor to misreport its position.
  5. A rare but possible cause could involve issues within the steering rack itself, which may need to be replaced if internal components have failed.
