OBD Diagnostics for Monitoring Power Steering System Performance

Modern vehicles increasingly use electric power steering (EPS) systems. When sensors or motors malfunction, steering can become heavy or unpredictable. OBD power steering diagnostics help identify faults that affect vehicle control.

How Electric Power Steering Works

Steering Torque Sensors

Measure driver input.

Electric Assist Motors

Provide steering assistance based on conditions.

Common Power Steering Issues

Sensor Calibration Errors

Cause inconsistent steering effort.

Motor or Control Failures

Result in loss of steering assist.

How OBD Diagnoses Steering Problems

Steering Angle and Torque Data

OBD monitors accuracy and response.

System Communication Checks

Detects EPS module faults.

Benefits of Power Steering Diagnostics

• Improved steering safety

• Consistent handling response

• Reduced repair time

Conclusion

OBD diagnostics ensure power steering systems operate smoothly and reliably.
