What is B0473?
The Diagnostic Trouble Code (DTC) B0473 indicates a problem with the steering angle sensor in your vehicle. This sensor is crucial for the stability control systems and functions by measuring the angle of the steering wheel. When B0473 is triggered, it generally means that the sensor is either sending an incorrect signal or has completely failed. This can lead to various issues including a loss of steering control or problems with the vehicle's stability control system. In practical terms, if you experience this code, your vehicle may struggle with handling, and you might notice the traction control light illuminating on your dashboard. This code is common in vehicles like the 2015-2018 Honda Accord and the 2016-2020 Toyota Camry, particularly if they have been involved in an accident or experienced electrical issues. Ignoring this code can lead to more severe handling problems and could pose safety risks while driving. Addressing the issue promptly will not only ensure the safety of your vehicle but also enhance overall driving performance.
