What is C008F?

The diagnostic trouble code (DTC) C008F indicates an issue with the vehicle's steering angle sensor, specifically related to the stability control system. This code often manifests when the vehicle's computer detects a discrepancy between the steering angle sensor and the expected values for vehicle performance. In essence, the steering angle sensor plays a crucial role in aiding systems like traction control and electronic stability control by providing real-time data about the steering wheel's position. If this sensor malfunctions or fails to send accurate signals, it can lead to issues like loss of control in slippery conditions or erratic vehicle behavior. Commonly found in models such as the 2015-2019 Chevrolet Silverado and GMC Sierra, the C008F code typically triggers the check engine light, and drivers may notice an increase in the vehicle's handling difficulties. Ignoring this code can result in compromised vehicle safety and performance, making it essential to address promptly.

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

Symptoms

Common symptoms when C008F is present:

  • The check engine light remains illuminated, indicating a fault in the steering angle sensor system.
  • Drivers may experience difficulty in steering, especially during sharp turns or while navigating slippery roads.
  • Increased traction control activation during normal driving conditions, leading to unexpected braking or loss of acceleration.
  • Unusual noises from the steering column when turning, suggesting an underlying mechanical issue.
  • The vehicle may exhibit erratic behavior, such as drifting or swaying, especially in adverse weather conditions.

Possible Causes

Most common causes of C008F (ordered by frequency):

  1. {'cause': 'Faulty steering angle sensor', 'likelihood': '60%', 'details': 'The most common cause of the C008F code is a malfunctioning steering angle sensor, which can occur due to wear and tear or electrical faults.'}
  2. {'cause': 'Wiring issues or poor connections', 'details': 'Corroded or damaged wiring can prevent the sensor from transmitting accurate readings, leading to C008F.'}
