DTC C1290: Torque Sensor Signal Error: General Description

The steering angle sensor has a function to sense a steering angle and a velocity of a steering wheel.

The procedure is as follows: A drive turns a steering wheel → Main/Sub-gear turns → Rotation angle senses → A steering angle is calculated.

The EPS(MDPS=Motor Driving Power Steering) CM uses signals of steering angle sensor and controls for its restoring and damping control.
