What is B08DC?

The B08DC diagnostic trouble code (DTC) is primarily associated with the power steering system in vehicles like the 2015-2018 Honda Civic and some other makes and models. This code indicates there's a malfunction within the steering angle sensor or its circuit. The steering angle sensor is crucial for many vehicle functions, including stability control and adaptive cruise control. When the B08DC code is triggered, it often means that the vehicle's computer has detected a discrepancy in the steering angle data being sent to the control module. This can result in issues like difficulty steering, loss of power steering assist, and even the activation of the vehicle's stability control system, which could make handling unpredictable. In practical terms, if you notice your steering feels stiff or unresponsive, or if warning lights appear on your dashboard, it's essential to address this issue promptly to ensure safe driving conditions. Ignoring this code could lead to more severe problems down the line, including increased wear on steering components and potential safety hazards while driving.

Symptoms

Common symptoms when B08DC is present:

  • The check engine light may illuminate, indicating a potential issue.
  • You might experience stiff steering, making it difficult to maneuver the vehicle, especially at low speeds.
  • Your vehicle may exhibit a loss of power steering assist, causing increased effort to turn the wheel.
  • The stability control system may activate unexpectedly, which can be disorienting and could affect driving safety.
  • You might notice irregularities in the vehicle's handling or a lack of responsiveness during turns.

Possible Causes

Most common causes of B08DC (ordered by frequency):

  1. The most common cause of the B08DC code is a faulty steering angle sensor, which occurs in about 60% of cases. This sensor is responsible for reporting the angle of the steering wheel to the vehicle's computer.
  2. A second likely cause could be a wiring issue, such as damaged or corroded wiring within the sensor circuit, which can disrupt communication between the sensor and the control module.
  3. Another potential cause is a malfunctioning power steering control module that fails to interpret the sensor's data correctly. Regular inspections can help prevent this issue by identifying worn components early.
  4. Less commonly, the problem may stem from a physical obstruction in the steering system, like debris or a mechanical failure in the steering column.
  5. In rare cases, software errors in the vehicle's control module can trigger the B08DC code, which would require a software update or reprogramming to resolve.
