What is C04C6?

The diagnostic trouble code (DTC) C04C6 is associated with a malfunction in the vehicle's steering angle sensor, which is crucial for various safety and handling features. When your vehicle's onboard computer detects a problem with the steering angle sensor, it triggers this code to alert the driver. This sensor plays a key role in systems like Electronic Stability Control (ESC) and Traction Control, which help maintain vehicle stability during adverse conditions. If C04C6 is active, you may notice that your stability control system is not functioning correctly, which could lead to dangerous driving situations, especially during wet or slippery conditions. Ignoring this code can lead to further complications, including increased wear on your tires and suspension components, as the vehicle might not handle as expected. It's essential to address this code promptly to ensure your safety and the longevity of your vehicle's systems. Regular maintenance, such as checking the steering components and ensuring proper alignment, can help prevent issues related to this code.

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

Symptoms

Common symptoms when C04C6 is present:

  • The check engine light or stability control warning light remains illuminated, indicating a potential issue with your steering system.
  • You may experience unusual handling characteristics, such as the vehicle feeling loose or unresponsive during turns, which affects driving confidence.
  • Fuel economy may decrease by about 10-15% as the vehicle compensates for incorrect steering inputs.
  • The traction control system may engage unexpectedly, leading to reduced acceleration or loss of power when driving.
  • In some cases, a noticeable grinding or clicking noise may be heard from the steering column when turning the wheel.

Possible Causes

Most common causes of C04C6 (ordered by frequency):

  1. The most common cause of C04C6 is a faulty steering angle sensor, which has a likelihood of about 60%. This sensor can wear out or fail due to electrical issues or physical damage.
  2. Another common cause is a loose or damaged wiring harness connected to the steering angle sensor. This issue can create intermittent connections and lead to erratic sensor readings.
  3. Improper vehicle alignment or suspension problems can also trigger this code, as they may affect the sensor's ability to accurately measure the steering angle.
  4. Less commonly, a malfunctioning electronic control unit (ECU) can misinterpret signals from the steering angle sensor, causing this error code to appear.
  5. Rarely, software issues within the vehicle's control systems may lead to false readings from the sensor, resulting in the C04C6 code appearing.
