What is B0AF1?

The B0AF1 diagnostic trouble code indicates a malfunction within the vehicle's steering angle sensor system, which is crucial for various stability and safety features. This code is particularly prevalent in vehicles such as the 2016-2020 Toyota RAV4, among others. When the B0AF1 code is triggered, it generally means that the steering angle sensor is out of calibration or has failed. The steering angle sensor provides critical data to the vehicle's stability control system, which helps ensure that the vehicle remains stable during sharp turns or slippery conditions. If this sensor is not functioning properly, it can lead to compromised vehicle handling and safety, making it imperative for drivers to address this issue promptly. Ignoring the B0AF1 code could lead to more severe problems, such as unexpected loss of traction control or anti-lock brake system functionality, which can increase the risk of accidents. Additionally, you may notice that your vehicle's warning lights remain illuminated, indicating that a system check is needed. Addressing DTC B0AF1 typically involves recalibrating or replacing the steering angle sensor, and it is often necessary to use specialized diagnostic tools, such as the GeekOBD APP, to diagnose the issue accurately and perform the necessary recalibrations.

Symptoms

Common symptoms when B0AF1 is present:

  • The check engine light and/or traction control warning light remain illuminated on the dashboard.
  • Steering feels unresponsive or overly loose, especially during turns.
  • The vehicle may exhibit unexpected handling characteristics, such as drifting or swaying.
  • There could be a noticeable decrease in fuel efficiency due to the vehicle's stability control system being compromised.
  • In some cases, the vehicle's advanced safety features may become disabled.

Possible Causes

Most common causes of B0AF1 (ordered by frequency):

  1. The most common cause of the B0AF1 code is a malfunctioning steering angle sensor, with a likelihood of 70%. This can occur due to wear and tear or electrical failures.
  2. Another potential cause is improper calibration of the steering angle sensor after a wheel alignment or suspension work, which can result in a 20% chance of triggering the code.
  3. A less common cause might be damaged wiring or connectors associated with the steering angle sensor, which can lead to intermittent faults.
  4. A serious but less frequent cause could be a malfunction within the vehicle's electronic control unit (ECU), which could require professional reprogramming or replacement.
  5. Lastly, rare instances of software glitches in the vehicle's stability control system can also trigger the B0AF1 code, necessitating a software update.
