What is C0347?

DTC C0347 indicates a malfunction related to the steering angle sensor, which is a crucial component in vehicles equipped with electronic stability control (ESC) and traction control systems. The steering angle sensor measures the position of the steering wheel, allowing the vehicle's computer systems to adjust the handling and stability based on the driver's input. When the C0347 code is triggered, it typically means that the sensor is either faulty or that there’s an issue with the wiring or connectors associated with it. This can lead to various performance issues, including reduced stability control, difficulty steering, or even the activation of the ESC warning light. For car owners, it's essential to address this issue promptly, as neglecting it can lead to unsafe driving conditions and increased wear on other components. Common models affected include the 2010 to 2016 Chevrolet Malibu, where drivers often report issues with steering feel and responsiveness when this code appears. Regular maintenance and checks of the steering components can help prevent such problems from escalating.

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

Symptoms

Common symptoms when C0347 is present:

  • The check engine light stays on constantly, indicating a fault within the vehicle's electronic systems.
  • Drivers may experience steering that feels loose or unresponsive, making it difficult to maintain control.
  • Fuel economy can decrease by 10-15% due to the vehicle's stability systems working harder to compensate for perceived steering issues.
  • The electronic stability control warning light may illuminate, signaling that the system is disabled.
  • Unusual noises when turning the steering wheel, which may indicate further mechanical issues.

Possible Causes

Most common causes of C0347 (ordered by frequency):

  1. Faulty steering angle sensor (60% likelihood): The most common cause of C0347 is a malfunctioning sensor, which can be due to wear and tear or manufacturing defects.
  2. Wiring issues (20% likelihood): Damaged or corroded wiring or connectors can lead to intermittent signals being sent to the vehicle's computer.
  3. Calibration issues (10% likelihood): If the steering angle sensor is not calibrated correctly after repairs or replacements, it can trigger the C0347 code.
  4. Software glitches (5% likelihood): Occasionally, the vehicle's software may need an update to ensure proper sensor operation.
  5. Less common but serious cause: Physical damage to the steering column that affects sensor placement.
