Where is the steering wheel angle sensor located?

[StJulian]

Steering wheel angle sensor is located inside the steering column below the steering wheel. The steering wheel angle sensor is a component of the vehicle stability control system, generally connected to the PCM via CAN bus. It can be divided into analog steering wheel angle sensors and digital steering wheel angle sensors. The commonly used steering wheel angle sensor adopts a mechanical structure with three gears to measure the rotation angle and the number of turns. The large gear rotates with the steering column, while two small gears (differing by one tooth) are fixed to the vehicle body along with the sensor housing and do not rotate with the steering wheel. The two small gears respectively collect the rotation angle of the steering wheel. Due to the one-tooth difference, different numbers of turns will result in specific angle differences, through which the absolute steering angle of the steering wheel can be calculated.
