The power steering control module (EPS module) manages the electric power steering motor, calculating the correct amount of assist based on speed and steering input.
If you notice any of the following, the part likely needs replacement:
Steering warning light on the dashboard
Heavy steering effort or inconsistent assist
Diagnostic fault code related to the module itself
Installation information
Mounted on or near the steering rack/column, connecting to the vehicle wiring harness — requires specialist calibration after replacement.
Frequently asked questions
This module calculates less assist at higher speeds for stability and more assist at low speed for easy parking manoeuvres — a fault here can disrupt this balance or remove assist entirely.
Super good! They came through with the part I needed, quickly and at a fair price! Thanks, and I definitely recommend!

I ordered a Heater Blower Motor Resistor for a Toyota Avensis. Delivery took eight days from Latvia to Ireland. I installed it, and everything works perfectly. I wish this company success.

No complaints about Evro Trans itself, everything's fine. But the delivery..... It felt like the order was being carried by turtles. 4 days from Riga to Daugavpils. Judging by the tracking, the parcel just sat somewhere behind a shed for 3 days, then they found it and delivered it the next day. I think that's why I won't be ordering there again.

Bought a front fender for my car. I liked it! After payment they sent more than 20 photos of the problem areas, and it was packed very securely - took a while to unwrap.
