What is C08B5?

The diagnostic trouble code (DTC) C08B5 indicates a malfunction related to the steering angle sensor. This sensor is crucial for various vehicle stability and safety systems, including traction control and electronic stability control. If your car has triggered this code, it typically means the steering angle sensor is not providing the expected range of motion or data to the vehicle’s onboard computer. This can lead to issues such as poor handling, a warning light on your dashboard, and potential safety risks while driving. Commonly seen in vehicles like the 2016-2022 Honda CR-V and the 2015-2020 Ford Edge, this problem can stem from various underlying issues, including sensor misalignment, faulty wiring, or even issues with the vehicle's software. Ignoring this code can lead to further complications, including increased difficulty in steering and compromised safety features. It's essential to address this code promptly to ensure your vehicle operates safely and effectively.

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

Symptoms

Common symptoms when C08B5 is present:

  • Check engine light illuminates and stays on, indicating a system fault that requires attention.
  • Vehicle exhibits poor handling characteristics, such as drifting or excessive steering effort while turning.
  • Increased wear on tires due to misalignment caused by a malfunctioning steering angle sensor.
  • Traction control or stability control warning lights may activate, indicating issues with these critical systems.
  • Unusual noises from the steering column or unexpected steering feedback, which can affect driving confidence.

Possible Causes

Most common causes of C08B5 (ordered by frequency):

  1. The most common cause is a misaligned or damaged steering angle sensor, which occurs in about 60% of cases. This can happen due to physical impacts or wear over time.
  2. Another frequent cause is faulty wiring or connections that result in intermittent signals being sent to the vehicle’s computer. This issue often accounts for around 25% of cases.
  3. Software glitches or calibration errors in the vehicle's computer system can also lead to this code, making up about 10% of occurrences. Regular software updates can help mitigate this risk.
  4. Less common but serious causes include failure in associated components such as the vehicle's power steering module, which may require additional diagnostic testing.
  5. Rarely, issues with the vehicle’s ABS system can trigger the C08B5 code due to shared electronic components.
