It typically means there’s a fault in the power steering system, most often in the electric power steering (EPS) setup on newer Hondas, or in the hydraulic system on older models. The warning can affect steering assist and handling, so it shouldn’t be ignored.
What the warning means
In Honda vehicles, the message is generated when the EPS control Module detects a fault in steering assist or in the communication with steering sensors or the motor. On models with hydraulic power steering, it can also indicate low fluid, a pump issue, or leaks. Depending on the exact fault, you may notice heavier steering, intermittent assist, or even sudden loss of steering assist while driving.
Common causes
Here are the most frequent reasons this warning appears in Hondas, spanning electric, hydraulic, and sensor-related issues.
- Faulty EPS motor or electric steering controller
- Steering angle sensor (SAS) or torque sensor fault
- Hydraulic power steering fluid low, contaminated, or pump failure (in models with hydraulic PS)
- Leaks or worn power steering hoses and connections
- Steering rack, column, or intermediate shaft problem
- Software/calibration needs, such as EPS recalibration or SAS reinitialization
Because EPS systems are integrated with other vehicle controls and safety systems, a fault can show up with additional warning lights or codes. A professional scan is typically required to pinpoint the exact cause.
What to do now
To address this warning, follow these practical steps:
- If the steering feels unusually heavy or stiff, pull over safely and stop. Do not continue driving aggressively.
- Check the power steering system if your model uses hydraulic PS: look for a low fluid level or signs of leaks around the reservoir and hoses.
- Inspect for obvious signs of trouble such as fluid puddles under the car or worn hoses.
- Check the vehicle’s battery and charging system; EPS can behave strangely if the battery is weak or the alternator is failing.
- Obtain a diagnostic code readout with an OBD-II scanner or have a professional read Honda-specific codes to identify EPS, SAS, or related faults.
- Schedule a service appointment with a qualified technician or a Honda dealer that has EPS diagnostic capabilities. Some faults require calibration, software updates, or component replacement.
- If you cannot drive safely, arrange towing to a shop rather than attempting a roadside repair.
Diagnosing the exact issue typically requires specialized tools and access to Honda’s diagnostic software, as EPS faults can involve the motor, sensor inputs, wiring, and the vehicle’s safety control logic.
Safety considerations
Power steering is a key safety feature. A failure can increase steering effort and reduce maneuverability, especially at low speeds or in emergency maneuvers. If the warning appears, minimize driving, seek professional diagnosis promptly, and follow the technician’s guidance on whether the car is safe to drive to a shop or should be towed.
Summary
The “Check Power Steering System” alert on a Honda signals a potential fault in the steering assist system, most often EPS on newer models or hydraulic PS on older ones. Causes range from motor/controller or sensor faults to electrical issues, hydraulic fluid problems, or worn steering components. Address the warning promptly with a diagnostic check, and avoid long or high-stress drives until the issue is resolved.
