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.
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.
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.
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:
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.
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.
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.
An aftermarket steering angle sensor replacement costs around $100 to $250. Some sensors are priced higher depending on their brand and specifications. Labor costs for a steering angle sensor replacement can go anywhere between $100 and $500. Rates may vary depending on other factors like your ride’s make and model.
If you’re a seasoned automotive DIYer, you can do the replacement on your own. However, if you don’t have the tools and technical know-how to replace your steering angle sensor, then it’s better to pay a mechanic to do the job for you.
The steering sensor is behind the steering wheel, so you’ll have to remove the steering wheel to reach it. You’ll also have to disconnect your battery and remove the steering column.
Many videos online show how to replace the steering angle sensor, so you can watch them for reference. However, keep in mind that the sensor’s location can vary depending on the vehicle.
For example, the sensor is in the steering gear on some vehicles. Meanwhile, some cars can also have two steering angle sensors, so you’ll have to make sure that you remove the right one.
Consult repair manuals with information specific to your ride’s make and model.
