What vehicles are most commonly affected by C0579?

Vehicles like the 2014-2019 Chevrolet Silverado and GMC Sierra are frequently affected by the C0579 code due to their common use of similar steering angle sensor systems.

How can I prevent C0579 from happening again?

To avoid future occurrences of C0579, ensure regular maintenance of your vehicle’s steering system, avoid rough driving conditions that could damage the sensor, and have any repairs performed by qualified technicians.

What is C0579?

The C0579 diagnostic trouble code indicates a calibration error with the steering angle sensor in your vehicle’s stability control system. Essentially, this code suggests that the steering angle sensor, which helps the vehicle determine its direction and stability, is not properly calibrated. This can lead to various issues, including reduced stability, impaired traction control, and potential safety risks while driving. In vehicles like the 2014-2019 Chevrolet Silverado and GMC Sierra, this code is commonly triggered due to changes in the sensor's position or failure to communicate correctly with the vehicle's onboard computer. If the steering angle sensor is not calibrated correctly, the vehicle may exhibit erratic handling or may not respond as expected in emergency situations, which can be both dangerous and frustrating for drivers. Addressing this issue typically requires recalibrating or replacing the sensor, depending on its condition and the underlying cause of the fault. If left unresolved, it can lead to further complications within the vehicle’s electronic stability control systems and affect overall vehicle performance.

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

Symptoms

Common symptoms when C0579 is present:

  • The check engine light illuminates, and in some cases, the stability control light may also stay on, signaling a fault in the steering angle sensor.
  • Drivers may experience unresponsive steering or feel as though their steering wheel is off-center, affecting handling and maneuverability.
  • There may be a noticeable decrease in fuel economy due to the vehicle's stability control system working harder to compensate for the sensor error.
  • The vehicle may exhibit difficulty in making sharp turns or may struggle with traction control during adverse weather conditions.
  • In some cases, the driver may receive warning messages on the dashboard regarding steering or electronic stability issues.

Possible Causes

Most common causes of C0579 (ordered by frequency):

  1. The most common cause of C0579 is a misaligned steering angle sensor due to improper installation or vehicle repairs, with an estimated likelihood of 60%.
  2. Another cause can be physical damage to the sensor or its wiring, resulting in a loss of communication with the vehicle's computer.
  3. A software issue within the vehicle's stability control system can also trigger C0579, especially after a recent update or during a diagnostic check.
  4. Less common but serious causes include a malfunctioning Electronic Control Unit (ECU) that fails to process signals from the steering angle sensor correctly.
  5. Rarely, a faulty steering column or steering rack can lead to this code, indicating a need for more extensive repairs.
