Where is the steering angle sensor installed?
2 Answers
The steering angle sensor is installed at the bottom of the steering column. The automotive steering angle sensor is used to detect the rotation angle and direction of the steering wheel. Whether turning left or right, it will be detected by the steering angle sensor, and the vehicle's electronic control unit will issue the correct steering command. The rotation angle of the steering wheel provides the basis for the vehicle's steering amplitude, ensuring the car follows the driver's steering intentions. The steering wheel angle sensor is applied in the vehicle dynamic stability control system, where its stability and accuracy are directly related to driving safety. It incorporates all the functions of the ABS system and can actively brake when the vehicle loses stability, thereby enhancing driving safety to a certain extent.
I remember one time at the repair shop, the technician felt around under the steering wheel and quickly located the steering angle sensor. That thing is usually installed at the top of the steering column, close to the steering wheel, to precisely detect how much you're turning. Since it's connected to safety systems like the ABS and electronic stability program, if the system misreports the angle while you're driving, it might trigger unnecessary braking interference, which is pretty annoying. That's why it's installed close to the steering wheel—to accurately track steering changes and ensure reliable operation of the vehicle's dynamic stability control. Last time my car threw a power steering fault code, the technician checked here and found that dust buildup on the sensor was affecting the signal.
