What is C055F?

The Diagnostic Trouble Code (DTC) C055F indicates a malfunction in the steering angle sensor, which is crucial for stability control systems in vehicles. This code is commonly found in vehicles like the 2014-2019 Chevrolet Silverado and GMC Sierra. The steering angle sensor monitors the angle of the steering wheel in relation to the vehicle's chassis and sends this data to the vehicle's electronic stability control system. If the sensor fails or provides inaccurate data, it can lead to a range of issues, including compromised safety features and potential handling problems. Drivers may experience erratic steering behavior or warning lights on the dashboard. In some cases, if left unaddressed, this issue could lead to more significant problems, such as decreased control during adverse driving conditions. Therefore, understanding and addressing DTC C055F is essential for maintaining vehicle safety and performance. If you encounter this code, it's important to diagnose the exact cause, as driving with a malfunctioning steering angle sensor can affect your vehicle's handling and overall safety.

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

Symptoms

Common symptoms when C055F is present:

  • The check engine light or stability control warning light may illuminate, indicating a problem with the steering angle sensor.
  • Drivers may notice that the steering feels unresponsive or delayed, particularly during sharp turns or sudden maneuvers.
  • In some cases, the vehicle may exhibit instability during braking or cornering, leading to a feeling of loss of control.
  • The anti-lock braking system (ABS) may malfunction, causing longer stopping distances or erratic behavior during braking.
  • Steering wheel position may not align with the vehicle's direction, leading to confusion when driving straight.

Possible Causes

Most common causes of C055F (ordered by frequency):

  1. The most common cause is a faulty steering angle sensor itself, which has a likelihood of about 70%. This can occur due to wear and tear or exposure to extreme temperatures.
  2. A second cause could be damaged wiring or loose connections, which accounts for approximately 15% of cases. Corrosion or fraying in wires can prevent proper signal transmission.
  3. Another potential cause is a malfunctioning electronic control unit (ECU) that processes data from the steering angle sensor, leading to incorrect readings and system failures.
  4. Less common but serious causes include issues with the steering rack or column, which may require extensive repairs if damaged.
  5. A rare cause might be a software glitch within the vehicle's onboard diagnostic system, which can sometimes be resolved with a simple software update.
