Electronic Power Steering (EPS) Light on a Toyota Supra
Have this checked promptly. It is not an immediate stop, but do not ignore it for long.
What the Electronic Power Steering (EPS) Light Means on a Toyota Supra
The EPS (electronic power steering) light on a Toyota Supra indicates a fault in the electric steering assist. Steering can become noticeably heavier, and the system may need a diagnostic reset or repair.
How Urgent Is the Electronic Power Steering (EPS) Light?
In terms of priority, treat this as a high concern on your Toyota Supra. The single most useful thing you can observe is whether the Electronic Power Steering (EPS) Light is steady or blinking: a steady light generally allows a careful drive to a safe location or a workshop, whereas a flashing light signals an active fault that can cause damage if you continue. Pay attention to changes in how the Toyota Supra drives, sounds, or smells, since those symptoms sharpen the diagnosis considerably.

Frequently Asked Questions
Why is the Electronic Power Steering (EPS) Light on in my Toyota Supra?
The Electronic Power Steering (EPS) Light illuminates on a Toyota Supra when the vehicle detects a condition in the related system that is outside its normal range. The exact reason can vary from something as minor as a loose connection to a component that needs replacing, which is why reading the stored trouble codes is the reliable way to know for certain.
Can I keep driving with the Electronic Power Steering (EPS) Light on?
For a Toyota Supra, a steady amber Electronic Power Steering (EPS) Light with normal driving generally allows a careful trip to a garage. A red or flashing light, or any change in performance, means you should stop and avoid further driving until the fault is identified.
How much does it cost to fix the Electronic Power Steering (EPS) Light on a Toyota Supra?
There is no single price for the Electronic Power Steering (EPS) Light on a Toyota Supra; it ranges from a no-cost adjustment to a component replacement. The honest way to control cost is to diagnose the exact code before authorising any repair, so you only pay to fix what is actually wrong.
Will the Electronic Power Steering (EPS) Light reset itself on a Toyota Supra?
Sometimes the Electronic Power Steering (EPS) Light on a Toyota Supra clears on its own once the condition that triggered it no longer exists — for example after several good drive cycles. More often, though, the light stays on until the underlying fault is repaired and the code is cleared, so treat a self-clearing light as a reason to still investigate.
