What vehicles are most commonly affected by C0341?

C0341 is frequently reported in models like the 2010-2015 Chevrolet Equinox and GMC Terrain, as well as other GM vehicles from the same era. Regular checks and maintenance can help prevent issues related to this code.

How can I prevent C0341 from happening again?

To prevent C0341, ensure regular maintenance of the steering system and check wiring and connections during routine inspections. Avoid harsh driving conditions that could damage the steering components, and always use quality replacement parts if repairs are needed.

What is C0341?

DTC C0341 refers to a fault in the steering angle sensor circuit. This code is particularly common in vehicles like the 2010-2015 Chevrolet Equinox and GMC Terrain, where the steering angle sensor plays a crucial role in the electronic stability control (ESC) and anti-lock brake system (ABS). When this code is triggered, it indicates that the steering angle sensor is providing erratic or incorrect data to the vehicle's control module. This can lead to various performance issues, including loss of traction control and stability assistance, which can compromise vehicle safety. The steering angle sensor measures the precise angle of the steering wheel and sends this data to the vehicle's computer. If the sensor is malfunctioning or if there's a wiring issue, the car may behave unpredictably, causing drivers to lose control in critical situations. Therefore, understanding this code is vital for maintaining safe driving conditions. If you see the C0341 code, it’s a strong indication that you should address the issue promptly to avoid potential risks associated with impaired vehicle control.

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

Symptoms

Common symptoms when C0341 is present:

  • The check engine light illuminates and remains on, indicating a persistent issue with the steering system.
  • Loss of traction control or stability assistance, making the vehicle feel unstable during turns or slippery conditions.
  • Erratic steering response where the steering feels loose or unresponsive, especially when making tight turns.
  • Increased wear on tires due to improper alignment caused by the faulty steering angle sensor.
  • Potential warning lights for the ABS system may also activate, indicating further underlying issues.

Possible Causes

Most common causes of C0341 (ordered by frequency):

  1. The most common cause of C0341 is a faulty steering angle sensor, which occurs in about 60% of cases. This sensor can wear out over time or suffer damage from road conditions.
  2. Wiring issues, such as frayed or corroded connectors, are the second most common cause, accounting for approximately 25% of C0341 triggers. These issues can disrupt the signal between the sensor and the vehicle's control module.
  3. Improper installation or calibration of the steering angle sensor during maintenance or repair work can lead to this code, making up about 10% of cases. It's crucial to ensure proper alignment and calibration after any repair.
  4. Less common but serious causes include a malfunctioning electronic control unit (ECU), which can lead to significant electrical problems in the system.
  5. Rarely, a mechanical issue within the steering system itself, such as a broken steering shaft or damaged gears, can trigger this code.
