Your vehicle uses many different sensors to monitor all kinds of parameters. One such sensor is the steering angle sensor, which helps monitor steering input.

What Is a Steering Angle Sensor?

The steering angle sensor (SAS) monitors steering input by detecting the steering wheel’s position and rate of rotation. The power steering control module gathers input from this sensor along with several other sensors to determine how much steering assist is required.

A vehicle usually has more than one steering angle sensor packed into one single unit. These sensors are typically located within the steering column.

In addition to acting as an input for the electronic power steering system (on vehicles so-equipped), the SAS plays a role in other systems, such as electronic stability control and lane keeping assistance.

Analog vs. Digital Steering Angle Sensor

Steering angle sensors come in two primary types: analog and digital. They have the same function, but they calculate data differently.

Analog sensors use differences in voltage signals to determine the steering’s rate of turn and angle positioning. Meanwhile, digital sensors use LED lights to measure the angle of the steering input.

Symptoms of a Bad Steering Angle Sensor

Like many other sensors, your ride’s steering angle sensors aren’t immune to wear. Here are some signs that your steering angle sensor needs replacement:

Illuminated Warning Lights

Your vehicle’s power steering and brake control units require data from steering angle sensors. Once your vehicle’s computers detect that there’s an issue, they will trigger warnings, such as the stability control and electronic power steering lights.

However, because a lot of vehicle issues can trigger these warnings, you can’t conclude immediately that they’re caused by your SAS.

Difficulty in Turning the Steering Wheel

A vehicle equipped with electric power steering needs data regarding the steering angle to work properly. A bad electric power steering sensor might send inaccurate signals to your ride’s computer, resulting in incorrect or unnecessary adjustments.

Awkward Steering After Wheel Alignment

When your vehicle is serviced for wheel alignment, you need to reset its steering angle sensors. If the mechanic fails to do so, these sensors might send inaccurate signals that can cause awkward steering.
