Electric Hydraulic Power Steering
C1260 Steering Angle Sensor Circuit-Signal - General Information

Component Location





General Description

Steering angle sensor is installed under the clock spring. Steering angle sensor input to MPU uses CAN communication in order to measure for speed of steering wheel's operation and angel.Steering angle sensor is composed with main gear and sub gear1, sub gear2 to determine for rotation direction.According to rotation of steering wheel, If the main gear rotate, sub gear1 and sub gear2 be retated. Steering angle sensor calculate rotation angle use MR effect of magnetic that installed in sub gear and different gear ratio sub gear1 and sub gear2. MPU determine driver's intention in accordance with Steering angle sensor and also using as a input value for EHPS (Electro Hydraulic Power Steering) control.

DTC Description

The MPU set this code If the input value of steering angle sensor is higher than maximum value or stuck with low status.
