What vehicles are most commonly affected by C0359?

The C0359 code is commonly seen in vehicles like the 2010-2015 Chevrolet Equinox and GMC Terrain. Other models from GM during this period may also experience similar issues, so it's important to check for recalls or technical service bulletins related to steering systems.

How can I prevent C0359 from happening again?

Regular maintenance of your vehicle's steering system can help prevent the C0359 code from reappearing. This includes checking the steering angle sensor and its wiring during routine inspections, keeping the system clean, and ensuring that any software updates for the ECU are applied.

What is C0359?

The diagnostic trouble code (DTC) C0359 is associated with the steering angle sensor, which plays a crucial role in the vehicle's stability control and traction control systems. Specifically, this code indicates that the signal from the steering angle sensor is out of range or is malfunctioning. The steering angle sensor detects the position of the steering wheel and sends this information to the vehicle's electronic control unit (ECU). When the ECU receives a faulty signal, it triggers the C0359 code. This can lead to various issues, such as a malfunctioning stability control system, increased tire wear, and poor handling characteristics. Car owners may notice symptoms like a warning light on the dashboard, difficulty in steering, or unusual handling during turns. Ignoring this code can lead to more severe problems, including compromised safety features. It is essential to address the C0359 code promptly to ensure optimal vehicle performance and safety.

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

Symptoms

Common symptoms when C0359 is present:

  • The check engine light or stability control warning light illuminates on the dashboard, indicating a potential issue with the steering system.
  • Drivers may experience difficulty in steering, with the steering wheel feeling loose or unresponsive during turns, which can lead to unsafe driving conditions.
  • A noticeable change in vehicle handling, such as pulling to one side or excessive tire wear, suggests that the steering angle sensor is not functioning correctly.
  • Unusual noises while turning the steering wheel can be heard, indicating possible underlying mechanical issues.
  • In some cases, the vehicle may enter limp mode, reducing power and speed to prevent further damage.

Possible Causes

Most common causes of C0359 (ordered by frequency):

  1. The most common cause of the C0359 code is a faulty steering angle sensor, which has a likelihood of around 60%. This sensor can fail due to wear and tear or electrical issues.
  2. Another possible cause is damaged wiring or connectors related to the steering angle sensor, which can lead to signal disruptions. This accounts for about 25% of cases.
  3. Improperly calibrated sensors can also trigger the C0359 code. Regular maintenance checks can help prevent calibration issues.
  4. Less common but serious causes include a malfunctioning electronic control unit (ECU), which may need reprogramming or replacement.
  5. Rarely, issues with the power steering control module can also result in the C0359 code, though this is less frequent.
