Maintaining your vehicle’s steering system is important for ensuring safe and efficient handling. One crucial component within this system is the steering angle sensor (SAS), which plays a significant role in providing accurate steering information to the vehicle’s electronic control units (ECUs). However, over time or due to certain circumstances, the SAS may need to be reset to ensure proper operation. Resetting the SAS without a scanner may seem like a daunting task, but it’s actually a relatively straightforward process that can be performed with basic tools and some technical know-how.
Before embarking on the SAS reset procedure, it’s important to understand the potential need for it. Some common reasons for resetting the SAS include steering wheel replacement, alignment adjustments, or vehicle stability system repairs. Additionally, if you notice any irregularities in your vehicle’s steering behavior, such as pulling to one side or difficulty centering the steering wheel, resetting the SAS may resolve the issue. Keep in mind that resetting the SAS requires precise steps and attention to detail, so if you’re not comfortable performing the process yourself, it’s always advisable to consult a professional mechanic.
The process of resetting the SAS without a scanner involves a combination of driving maneuvers and manual adjustments. Firstly, ensure the vehicle is parked on a level surface and the tires are facing straight ahead. Next, disconnect the battery negative terminal for a few minutes to reset the vehicle’s electrical system. Reconnect the battery and turn the ignition switch to the “ON” position, but do not start the engine. Rotate the steering wheel smoothly and fully from one extreme lock to the other, holding each position for a few seconds. Return the steering wheel to the center position and turn off the ignition. Repeat this sequence three times to ensure a thorough reset. Finally, start the engine and check if any steering irregularities have been resolved. If the problem persists, further diagnosis or calibration may be necessary.
How To Reset Steering Angle Sensor Without Scanner
The steering angle sensor (SAS) is a critical component of your vehicle’s stability control system. It measures the angle of the steering wheel and sends this information to the electronic control unit (ECU). The ECU uses this information to adjust the vehicle’s stability control system. If the SAS is not calibrated correctly, it can cause the stability control system to malfunction, which can lead to an accident.
There are two ways to reset the SAS: using a scanner or manually. If you have access to a scanner, the process is simple. Simply connect the scanner to the vehicle’s diagnostic port and follow the on-screen instructions.
If you do not have access to a scanner, you can reset the SAS manually. However, this process is more complicated and requires more specialized knowledge. It is important to note that resetting the SAS manually can void your vehicle’s warranty. If you are not comfortable performing this procedure, it is best to take your vehicle to a qualified mechanic.

How does steering angle sensor work?
The steering angle sensor (SAS) is a device that measures the angle of the steering wheel. This information is used by the vehicle’s electronic stability control (ESC) system to help keep the vehicle stable during cornering. The SAS is typically located on the steering column, and it uses a variety of sensors to measure the steering wheel angle.
What are the symptoms of a bad steering angle sensor?
The symptoms of a bad steering angle sensor can include:
- Difficulty steering
- Vehicle pulling to one side
- Stability control system not functioning properly
- Check engine light on
Can I reset the steering angle sensor myself?
Yes, you can reset the steering angle sensor yourself. However, this process is more complicated than using a scanner, and it requires more specialized knowledge. It is important to note that resetting the SAS manually can void your vehicle’s warranty. If you are not comfortable performing this procedure, it is best to take your vehicle to a qualified mechanic.
