Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Inspect and Adjust Steering Angle Sensor

Tools Required: OBD-II scanner, torque wrench.
Connect the OBD-II scanner to the vehicle's diagnostic port.
Navigate to the steering angle sensor settings and check for calibration.
If miscalibrated, follow the on-screen instructions to recalibrate the sensor.
Torque any loose connections back to the manufacturer’s specification.

3. Inspect Steering Components

Tools Required: Socket set, wrench set, jack stands.
Raise the front of the vehicle using a jack and secure it with jack stands.
Visually inspect the steering rack, tie rod ends, and other steering components for any signs of wear or damage.
If any components are found to be worn, replace them with OEM parts.

4. Test Electric Power Steering System

Tools Required: Multimeter, diagnostic software (if available).
With the vehicle in the "ON" position, use the multimeter to check the voltage at the EPS motor connector.
Compare the readings to manufacturer specifications to determine if the EPS system is functioning correctly.
If readings are out of range, consider replacing the EPS motor.
