Regular maintenance, including checking the steering system and ensuring proper installation of components, can help prevent B07AF. Additionally, keeping the vehicle's electrical connections clean and free from corrosion can prolong the lifespan of the steering angle sensor.

What is B07AF?

The Diagnostic Trouble Code (DTC) B07AF indicates a malfunction in the steering wheel angle sensor, which plays a crucial role in the vehicle's stability control system. This sensor measures the angle of the steering wheel, allowing the vehicle's computer to adjust the traction control and stability control systems accordingly. When a fault is detected, it can lead to issues such as impaired handling, unexpected vehicle behavior during turns, or even the activation of the stability control warning light on the dashboard. In simpler terms, if your vehicle has this code, it might not respond correctly to steering inputs, which could compromise your safety while driving. This code is particularly common in vehicles like the 2016-2021 Toyota Camry and the Honda Accord, where electronic stability control systems rely heavily on accurate sensor data. Ignoring this code can lead to more severe problems, including increased tire wear and reduced overall vehicle performance. Therefore, diagnosing and addressing the B07AF code promptly is essential for maintaining your vehicle’s safety and integrity.

Symptoms

Common symptoms when B07AF is present:

  • The check engine light or stability control warning light illuminates on the dashboard, indicating a problem with the steering system.
  • Drivers may notice that the vehicle feels unstable during sharp turns, leading to a lack of confidence while maneuvering.
  • Increased tire wear may occur due to misalignment caused by the steering angle sensor malfunction, which can lead to additional repair costs.
  • The steering may feel excessively loose or tight, making it difficult to maintain control over the vehicle.
  • The vehicle’s traction control system may activate unexpectedly, causing abrupt engine power reduction during normal driving conditions.

Possible Causes

Most common causes of B07AF (ordered by frequency):

  1. The most common cause is a faulty steering wheel angle sensor, which can occur in about 70% of cases due to wear and tear over time.
  2. Another frequent cause is damaged wiring or connectors related to the sensor, often resulting from exposure to moisture or road debris.
  3. Improper installation of the sensor during repairs or maintenance can lead to miscalibration, affecting its functionality.
  4. Less common but serious causes include issues with the vehicle’s Electronic Control Unit (ECU), which may require professional reprogramming.
  5. Rarely, a software glitch in the vehicle’s stability control system might trigger the B07AF code, necessitating a system update.
