What is B07B2?

DTC B07B2 refers to a specific diagnostic trouble code that signals a malfunction within the vehicle's body control module (BCM) related to the steering wheel angle sensor. This code can arise in various vehicles, but it's particularly prevalent in models like the 2015 to 2018 Honda Accord and the 2016-2019 Honda Civic. When this code is triggered, it often indicates that the BCM is not receiving accurate data from the steering angle sensor, which plays a crucial role in systems like electronic stability control and power steering. Failure to address this issue can lead to erratic steering behavior, potential loss of control, and even increased wear on other vehicle components. Car owners may notice symptoms such as the check engine light illuminating, difficulty in steering, or unexpected changes in steering responsiveness. It's essential to diagnose and repair the underlying issue promptly to ensure vehicle safety and performance. Ignoring this code may lead to more significant problems and costly repairs down the line, making it imperative for drivers to understand its implications and seek professional assistance if necessary.

Symptoms

Common symptoms when B07B2 is present:

  • The check engine light stays on constantly, indicating an ongoing issue that requires attention.
  • Drivers may experience steering hesitations or inconsistencies, potentially leading to unsafe driving conditions.
  • Fuel economy may decrease by 10-15% as the vehicle compensates for the steering anomaly affecting overall efficiency.
  • Unexpected changes in steering response can lead to difficulty maneuvering the vehicle properly in various driving conditions.
  • A noticeable increase in steering effort, particularly at low speeds, may occur, making driving uncomfortable.

Possible Causes

Most common causes of B07B2 (ordered by frequency):

  1. The most common cause is a faulty steering angle sensor, which has a likelihood of about 60%. This sensor can wear out or malfunction due to environmental factors.
  2. A second cause could be damaged wiring or connectors between the steering angle sensor and BCM, potentially leading to communication issues. Regular inspections can help prevent this.
  3. Improper calibration after repairs or replacements can lead to the B07B2 code as well. Ensuring proper calibration during maintenance can prevent recurring issues.
  4. Less common but serious causes include issues with the body control module itself, which may require replacement if damaged.
  5. A rare cause could be software glitches in the vehicle's onboard computer systems, which may need a software update to resolve.
