Kia Rio: Steering Angle Sensor (Except MDPS) Description

The steering angle speed sensor detects the angle of the steering wheel in order to which direction a user chooses.The sensor is detached on the Mutil-Function Switch (MPS) under the steering wheel.

Measureing Principle

The split of the steering angle sensor detects a steering angle of the steering wheel by a ON/OFF pulse caused by whether or not the LED lights go through the hole of the split, rotating as the steering wheel revolves. There are three LEDs, two(ST1, ST2) for detecting a steering direction, and the other for the neutral position.The HECU calculates the steering angle by the pulse from the steering angle sensor.

Calibration (Setting up the zero angle)

Steering Wheel Angle Sensor of a absolute angle type (CAN type) measures the angle under the standard of the zero angle set.

Calibration must be performed as following cases.

Calibration procedure

Perform wheel alignment and stand the steering wheel in a line within ±5°error.

Steering Angle Sensor (MDPS Only) Description

The Steering Angle Sensor (SAS) is installed in MDPS (Motor Driven Power Steering) and it sends messages to HECU through CAN communication line. The SAS is used to determine turning directio ...
