Check the fluid level; if low, add Honda power steering fluid to the appropriate level.
If the fluid is dirty or contaminated, drain and replace it.

4. Inspect Wiring and Connectors

Visually inspect the wiring harness and connectors associated with the EPS system.
Look for frayed wires or corrosion; repair or replace as needed.

5. Test Steering Angle Sensor

Connect a multimeter to the steering angle sensor.
Rotate the steering wheel slowly and observe readings. Ensure they match specifications from the service manual.
Replace the sensor if it fails to operate within the specified range.

6. Reconnect Battery and Test

Reconnect the battery terminals, ensuring they are tight.
Start the engine and check if the EPS light remains illuminated.
