Can wheel alignment affect steering angle sensors?
Since a front end alignment is designed to align the front wheels along with the steering wheel, it can cause problems with the steering angle sensor. It’s very common for many mechanic shops to forget to reset or realign the steering angle sensor after they’ve completed their service.
What does a steering wheel angle sensor do?
The steering angle sensor (SAS) determines where the driver wants to steer, matching the steering wheel with the vehicle’s wheels. Located within the steering column, the steering angle sensor always has more than one sensor packaged together in a single unit for redundancy, accuracy, and diagnostics.
How do you test the steering angle sensor?
To test the SAS, you have to back probe a connector that is typically under the steering column. As the steering wheel is turned 360 degrees, the SAS produces a signal that toggles between 0 and 5 volts. As the wheel is turned lock-to-lock, the voltage will reach 5 volts three times and 0 volts three times.
How do I calibrate my steering angle sensor?
Calibration is normally done with a scan tool. Sometimes the vehicle will need to be on an alignment rack. The calibration process is normally done by putting the wheels in the straight forward position, and then zeroing out the sensor with a scan tool.
What do you need to know about the steering angle sensor?
What is Steering Angle Sensor? The steering angle sensor ( SAS) is a critical part of the ESC system that measures the steering wheel position angle and rate of turn. When you need to reset the Steering Angle Sensor?
Which is part of ESC measures steering angle?
The steering angle sensor ( SAS) is a critical part of the ESC system that measures the steering wheel position angle and rate of turn.
How is the angle of the steering wheel measured?
The angle of the steering input is measured by an LED light. The sensor will read the information from the LED light and then send signals to your car’s computer system. From there your car’s system will use an algorithm to make sure the steering angle is accurate. This occurs from the steering wheel to the wheels.
Why is my steering wheel postion sensor not working?
It’s very common for many mechanic shops to forget to reset or realign the steering angle sensor after they’ve completed their service. This can cause the symptoms above to occur, such as lighting the Traction Control Light, Check Engine Light, or impacting the drivability of the vehicle.
