What is C0B08?

The DTC C0B08 code is a diagnostic trouble code that typically indicates an issue with the vehicle's steering angle sensor or related components. This code can be present in various vehicles but is notably common in the 2015 to 2018 Ford F-150 models. The steering angle sensor plays a crucial role in vehicle stability control systems, including Electronic Stability Control (ESC) and Anti-lock Braking System (ABS). When the C0B08 code is triggered, it usually means that the vehicle's computer has detected a malfunction or abnormal reading from the steering angle sensor. This can lead to issues such as improper steering response, which can compromise the safety and performance of the vehicle. Drivers may also experience warning lights on the dashboard, indicating that there's a problem. Ignoring this code can lead to more severe steering issues over time, potentially resulting in costly repairs or unsafe driving conditions. Therefore, understanding the implications of the C0B08 code is essential for maintaining vehicle safety and functionality. Regular diagnostics and timely repairs can prevent further complications and ensure a smooth driving experience.

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

Symptoms

Common symptoms when C0B08 is present:

  • The check engine light remains illuminated, indicating a persistent issue that needs addressing.
  • Drivers may notice difficulty in steering, such as a delayed response when turning the wheel, which can affect driving control.
  • A decrease in fuel economy might occur, with reports of up to a 10% dip, as the vehicle's systems attempt to compensate for the malfunction.
  • Unexpected activation of the stability control system, causing the vehicle to engage ABS when it shouldn't.
  • Dashboard warnings related to steering assist may appear, alerting drivers to the potential severity of the issue.

Possible Causes

Most common causes of C0B08 (ordered by frequency):

  1. The most common cause is a faulty steering angle sensor, which can account for roughly 70% of C0B08 cases. This component may fail due to wear and tear or electrical issues.
  2. Another frequent cause is damaged wiring or loose connections in the sensor circuit, which can lead to intermittent failures and may be exacerbated by environmental factors like moisture or corrosion.
  3. Improper alignment or suspension issues can also trigger the C0B08 code, as these may affect the sensor's readings. Regular alignment checks can help prevent this.
  4. Less commonly, a malfunctioning body control module (BCM) can misinterpret signals from the steering angle sensor, resulting in the C0B08 code.
  5. In rare instances, software bugs in the vehicle’s onboard computer may lead to false readings, necessitating a software update to resolve the issue.
