How does Honda power steering work?
Power steering is an essential feature in modern vehicles, including Honda models, that enhances the driver's ability to steer the car with ease. Understanding how Honda power steering works can help you appreciate its importance and recognize potential issues that may arise. In this article, we will explore the mechanics behind Honda's power steering systems, including the differences between hydraulic and electric power steering.
Types of Power Steering Systems
Honda vehicles typically utilize two main types of power steering systems: hydraulic power steering (HPS) and electric power steering (EPS). Each system has its own unique mechanisms and benefits.
Hydraulic Power Steering (HPS)
Hydraulic power steering systems use hydraulic fluid to assist in steering. Here’s how it works:
- Hydraulic Pump: The system is powered by a hydraulic pump, which is usually driven by the engine. This pump generates pressure in the hydraulic fluid.
- Fluid Flow: When the driver turns the steering wheel, the movement is transmitted to the steering gear, which directs the flow of hydraulic fluid to the appropriate side of the steering mechanism.
- Assistance: The pressure from the hydraulic fluid helps to move the steering gear, making it easier for the driver to turn the wheel.
Hydraulic power steering provides a strong and responsive feel, especially at low speeds, making it easier to maneuver the vehicle in tight spaces.
Electric Power Steering (EPS)
Electric power steering systems have become more common in newer Honda models. This system operates differently:
- Electric Motor: Instead of a hydraulic pump, EPS uses an electric motor to provide steering assistance. This motor is typically mounted on the steering column or the steering rack.
- Sensor Feedback: The system uses sensors to detect the driver's steering input and vehicle speed. Based on this data, the electric motor adjusts the level of assistance provided.
- Efficiency: EPS is more energy-efficient than hydraulic systems since it only draws power when steering assistance is needed, which can lead to improved fuel economy.
Electric power steering systems also allow for advanced features such as variable steering ratios and integration with other vehicle systems, enhancing overall driving dynamics.
Common Issues with Power Steering
While Honda power steering systems are generally reliable, they can experience issues over time. Here are some common problems to watch for:
- Fluid Leaks: In hydraulic systems, leaks can lead to a loss of steering assistance.
- Noise: Unusual noises when turning the steering wheel may indicate low fluid levels or a failing pump in hydraulic systems.
- Warning Lights: In EPS systems, warning lights on the dashboard may indicate a malfunction in the electric motor or sensors.
Regular maintenance and timely repairs can help ensure your Honda's power steering system remains in optimal condition, providing you with a safe and enjoyable driving experience.
Frequently Asked Questions
Do I really have to use Honda power steering fluid?
Yes, Hondas require a specific fluid. Using conventional fluid may result in a steering rack leak and/or shuddering felt in the steering wheel.
Why does Honda have special power steering fluid?
Yes, genuine Honda power steering fluid is synthetic. Synthetic fluid flows more smoothly at low temperatures, which enhances the lubrication of the pump and increases the system's lifespan.
How does the power steering system operate?
The hydraulic pressure typically comes from a gerotor or rotary vane pump driven by the vehicle's engine. A double-acting hydraulic cylinder applies a force to the steering gear, which in turn steers the roadwheels. The steering wheel operates valves to control flow to the cylinder.
Does electric power steering have fluid?
Electric power steering (EPS) systems, unlike their hydraulic counterparts, don't require any fluid to function. These systems also have fewer moving parts and, instead of pulling power from the engine, EPS draws power from an electric motor.

What happens if you put non-Honda power steering fluid in a Honda?
Power steering fluid not specifically made for Honda vehicles will quickly destroy your pump, and cause hundreds of dollars of damage in a short time. It's NOT worth trying to “save” 50 cents to use the wrong fluid. Power steering fluid is NOT “all the same”.
What happens if I don't change my power steering fluid?
Over time, the fluid will break down and become contaminated with particles. This could harm the pump and other parts of the steering system. Replacing the fluid and getting a power steering flush will help prevent these issues from occurring and affecting the car's performance.
What year did Honda start using electric power steering?
1990
In 1990 Honda introduced on the NSX its first electric power steering (EPS). This EPS system was developed to offer a steering feel worthy of a high performance mid-engined sports car.
How does Honda electric power steering work?
EPAS systems work by using an array of sensors, control units and an electric motor. A torque sensor mounted to your car's steering column measures the amount of force you apply to the steering wheel. The torque sensor, along with vehicle speed and steering angle sensors, sends this information to a control module.
Does Honda electric power steering have fluid?
No fluid with an electronic power steering system.
