About EPS in Lexus
EPS in Lexus stands for Electric Power Steering. It is a system that replaces the previous hydraulic steering pump in the IS 250, IS 350, and IS F models. The Lexus CT 200h is also equipped with EPS, which is powered by the hybrid battery and improves fuel economy by consuming power only when steering force assistance is needed. This system is highly durable, requires no hydraulic fluid, and provides a quick steering ratio of 14.6:1 with just 2.7 turns lock-to-lock. The speed-sensitive EPS in the Lexus CT 200h is noted as the most direct steering in the Lexus model range. Additionally, the steering precision is improved through the mounting of the gearbox directly to the suspension subframe for greater installation rigidity, promoting enhanced driver feedback and a more linear steering feel.
EPS Failure in Lexus
In the event of an EPS failure, the steering wheel may become hard to turn while the engine is on. This indicates an EPS failure, and it is recommended to stop the engine and then start it again. While this may temporarily recover the EPS, it is advised to seek diagnostics and repair as soon as possible to restore normal function. The EPS light comes on when the computer detects an issue with the vehicle’s electronic power steering system. One common problem with the EPS system is a faulty power steering control module (PSCM) .
Diagnostic and Repair
In case of EPS outage, it is recommended to seek diagnostics and repair as soon as possible to restore normal function. The EPS system is a useful invention that significantly facilitates car driving and reduces the effort a driver applies to turn the wheel. The EPS system relies on a computer-controlled electric motor to operate the steering rack, and the control module for the EPS system has detected a fault in the system.
Conclusion
EPS in Lexus vehicles is an innovative system that enhances fuel economy, steering precision, and driver feedback. In the event of an EPS failure, it is important to seek diagnostics and repair to restore normal function and ensure safe driving.

How do I fix my ESP light on my car?
Connect your car with an Obd-2 scanner to search for fault codes. If the steering angle sensor shows a fault code, reset the steering angle sensor using the scanner. Most of the time, the ESP BAS light will go away. If it doesn’t, then your steering angle sensor needs a replacement.
How do I know if my EPS module is bad?
Symptoms: Uneven response to steering wheel turns. Lack of assistance in specific steering directions. Rack movement without driver input during engine startup.
Can I drive my car if the EPS light is on?
With the light on, it simply means that some of your traction controls are not functioning correctly. So it’s still safe to drive, but you need to be extra careful because your traction controls are not functioning properly, so you can skid (if braking too hard), or spin tires (if accelerating too hard).
How do you fix the EPS light?
Often, you can fix the problem by pulling off the road, shutting the car off, and letting it sit for a minute. When you turn the car back on, the system will reset itself. If it doesn’t, you need to have the steering system inspected as soon as possible.
Does ESP affect steering?
The Electronic Stability Programme (ESP) in a car is a safety feature that improves a vehicles stability by detecting and reducing loss of traction. When the ESP detects loss of steering control, it automatically applies the brakes to help stabilise the vehicle.
What does the EPS warning light mean?
Electric Power Steering System
If the Electric Power Steering System does not operate normally, the warning light will illuminate on the instrument cluster. The steering wheel may become difficult to control or operate abnormally. In this case, have the system inspected by a professional workshop.
How serious is a EPS light?
If the EPS light is on, it means that the power steering system is not working properly and you may experience difficulty or stiffness in turning the steering wheel. There are several reasons why the EPS light may come on and prevent your car from starting. Some of the common ones are: A faulty battery or alternator.
How much does it cost to replace the EPS module?
The EPS got cutoff, and the warning light came up on the dashboard. After performing a scan diagnosis for detecting failure codes, the service advisor told me that both the EPS control unit that costs ₹12,000 and the EPS motor that costs ₹6500 needs to be replaced, as they both show failure code.
What would cause the EPS light to come on?
When your car is running low on power steering liquid, it will trigger the warning. A bright EPS light may also come on if your car has an electronic power steering (EPS) system. Since EPS has no fluid, there won’t be any fluid for you to monitor or maintain. Instead, the flaw may be due to an electrical fault.
Does EPS affect steering?
When you turn the steering wheel, the EPS control unit senses the input and provides the appropriate amount of assist. One of the primary benefits of EPS is its efficiency: it only uses power when the steering wheel is turned, and it doesn’t require power steering fluid, unlike its hydraulic counterpart.
