Prius Abs Light Brake Light And Traction Control Light On

In the world of automotive maintenance, ensuring your vehicle’s safety systems are in top condition is paramount. One crucial component often requiring calibration is the steering angle sensor. This sensor, prevalent in models like the 2013 Toyota Prius, demands proper calibration to maintain optimal functionality.

Calibrating the steering angle sensor doesn’t necessarily mandate specialized tools; it’s a task that can be achieved using simple techniques and understanding. In this guide, we’ll navigate through the steps and techniques necessary to recalibrate your steering angle sensor effectively.

Understanding the Process

The process involves a strategic manipulation of the vehicle’s onboard diagnostic connector, commonly referred to as the OBD2 connector. Contrary to common belief, you don’t always need an advanced scan tool for this procedure. Instead, simple tools like a paperclip can serve the purpose effectively.

To initiate the calibration process, locate pins number four and thirteen on the OBD2 connector, typically found beneath the dashboard. By shorting these pins using a paperclip, you create a circuit essential for the sensor reset.

Executing the Calibration

With the pins shorted, proceed by turning the ignition key to the ‘on’ position. At this stage, the dashboard might display an array of flashing lights, indicating the reset process has commenced. Allow this sequence to continue for approximately 30 to 40 seconds.

After this duration, turn the ignition off, remove the paperclip from the pins, and start the vehicle. You might still notice some flashing lights initially, but these should dissipate as the reset finalizes.

Ensuring Success

It’s imperative to ensure the steering wheel is precisely centered before commencing this procedure. This step is critical for the sensor to accurately recalibrate. Once the process is complete, the absence of warning lights on the dashboard indicates a successful reset.

However, it’s crucial to note that this method primarily addresses resets required after a wheel alignment or wheel bearing replacement. Persistent warning lights might indicate deeper issues, such as a faulty ABS speed sensor or wire failure within the vehicle’s system.


In conclusion, the recalibration of the steering angle sensor in Toyota and Lexus vehicles is a manageable task, even without sophisticated diagnostic tools. Following these outlined steps can effectively reset the sensor, provided the issue arises from a recent wheel alignment or wheel bearing replacement.

For persistent warning lights or complex issues within the vehicle’s safety systems, professional diagnostic tools and assistance might be necessary. However, for routine calibration after specific maintenance tasks, this method proves effective and accessible.
