Steering wheel angle sensor failure, symptoms of steering angle sensor failure

The steering wheel angle sensor is used to detect the rotation angle, direction and speed of the steering wheel. It is an integral part of the vehicle stability control system. It is also called the steering angle sensor. It is installed in the steering column below the steering wheel and is generally connected to the PCM via the CAN bus. .

After the steering angle sensor detects the car’s steering signal, it sends the car’s electronic control unitYuanThe correct steering command is issued to provide the basis for the steering range of the car. The electronic control unit of the car judges the amount of side force when the car is turning according to the signal of the speed sensor and the signal of the steering wheel angle sensor, so as to control the tilt of the body, so that the car can follow the driver's Turn to intent to drive.

ESP electronic stability program, activesuspensionThe system, EPS electronic speed-assisted power steering, follow-up turn headlights and other systems all need the assistance of the steering wheel angle sensor. When the steering wheel angle sensor fails or is damaged, the above systems will not work properly, and will affect the car's steering, causing misdirection, shaking, deviation and insensitive response, which will bring safety hazards to driving. Once the steering angle sensor fails, it should be repaired or replaced in time to ensure that the car turns normally and ensure driving safety.
