Honda's Electric Power Steering (EPS) is the electric-motor-assisted steering system used in most Honda vehicles, replacing the older hydraulic pump with an electric actuator to provide steering assist on demand.
In practice, EPS uses sensors to gauge how hard the driver is turning the wheel, and an onboard controller energizes a motor to help turn the steering rack. The system adjusts the amount of assist based on vehicle speed, drive mode, and other inputs, delivering light steering at parking speeds and firmer feedback on the highway while enabling tighter integration with safety and driver-assistance features.
How EPS works in Honda vehicles
In Honda cars, the EPS system uses a compact electric motor attached to the steering mechanism. A torque sensor in the steering column detects the driver's input, while sensors measure vehicle speed and, in some cases, brake status and wheel angle. The EPS control unit processes this data and applies assist torque to the rack, reducing the effort required to steer without using hydraulic fluid. This setup improves energy efficiency and supports a more programmable steering feel that can vary with mode or speed.
Benefits of Honda EPS
The following points highlight the ways EPS can change the steering experience and vehicle efficiency for Honda drivers.
- Lower energy use and improved fuel efficiency thanks to eliminating a hydraulic pump and fluid system
- Variable steering assist that scales with speed, providing easy maneuvering at low speeds and stable highway feel
- Quieter operation due to the absence of a hydraulic pump
- Better integration with driver-assistance systems like Lane Keeping Assist and Adaptive Cruise Control
- Lower maintenance risk and fewer fluid leaks, thanks to the simpler electric architecture
In summary, EPS contributes to a more responsive yet efficient steering system that can adapt to different driving scenarios and safety features across Honda's lineup.
EPS integration with safety features and the Honda lineup
Honda's EPS is designed to work in concert with the automaker's safety and driver-assistance suite, Honda Sensing. The assisted steering can aid active safety features by providing precise torque during lane-keeping maneuvers and when the Adaptive Cruise Control system maintains a following distance. EPS is standard across most modern Honda models, including the Civic, Accord, CR-V, HR-V, Pilot, and Odyssey, giving drivers consistent steering feel across the lineup.
Maintenance and reliability considerations
As with any electronically controlled system, EPS relies on sensors, wiring, actuators, and software. Common issues are electronic faults or sensor calibration errors rather than mechanical failures, and warning lights will alert the driver if a fault is detected. In many cases, steering effort remains possible if assist is temporarily unavailable, but the feel may be heavier until service is performed. Regular software updates and inspections can help keep EPS performing as intended.
Summary
Honda's EPS is the brand's electric power steering system, which uses an electric motor to provide steering assist on demand, replacing hydraulic assistance. It improves fuel efficiency, enables adaptive steering feel, and integrates with Honda's safety technologies to enhance driver support, while reducing maintenance concerns and allowing better control of steering dynamics across the lineup.
What is the EPS issue with Honda?
The Honda lawsuit alleges that Honda knew since at least 2016 that its EPS steering systems had one or more defects that caused its Honda and Acura vehicles to become harder to steer. The plaintiffs alleged that the EPS steering systems would malfunction while driving at highway speeds.
Can I drive with an EPS light on?
Can I drive my car with the power steering warning light on? It is not recommended to drive a vehicle with the red power steering warning light on. If the power steering system fails, the car will become difficult to steer, making it potentially dangerous to drive.
How do I know if my EPS is bad?
You'll know your EPS is bad if you feel stiffness when turning, hear unusual noises, or see the EPS warning light on your dashboard. Pay attention to these signs for potential malfunctions needing immediate attention. Does Electric Power Steering Need Maintenance? Yes, electric power steering needs maintenance.
How much does EPS cost to repair?
Repair cost ranges: Minor fixes (blown fuse/steering-angle sensor): $100–$300. EPS motor: $300–$800. Full steering column replacement: $530–$1,550.
