OBD Diagnostics for Electronic Power Steering Systems

Electronic Power Steering (EPS) replaces hydraulic systems with electric motors and sensors. OBD power steering diagnostics ensure the system delivers the correct steering assistance.

How Electronic Power Steering Works

Steering Torque Sensors

Measure driver input on the steering wheel.

Electric Assist Motors

Provide variable assistance based on speed and conditions.
