Welcome to Just Answer. I understand you're experiencing issues with your EPS, and I'm here to assist you in resolving this matter. If I happen to be assisting someone else or need to step away during our conversation, please rest assured that I will follow up as soon as I am available again.

Do you possess a diagnostic tool that can display the stored codes?Have you inspected for any worn or binding front steering and suspension joints?Are the front tire pressures at the correct levels?

Thank you,

Check the electronic power steering rack and pinion/module/motor. Measure the yellow/red wire for constant battery voltage, and check the green wire for voltage when the key is on. Perform an ohm test on the black/green wire to the chassis ground; you should see no resistance.

If everything checks out, leave the connector unplugged and connect a headlight bulb to the yellow/red wire and black/green wire. If the bulb shines brightly, the likely issue is a faulty rack and pinion.
