The power steering warning on a Honda signals a fault in the vehicle’s steering assist system, typically the electric power steering (EPS). When this light is on, you may have reduced or no steering assist, which can make steering heavier, especially at low speeds; have the system inspected as soon as possible.
What the warning looks like on a Honda dashboard
Dash indicators vary by model and year, but the warning is usually recognizable by a steering wheel icon accompanied by a message or abbreviation such as “Power Steering” or “EPS.” The indicator is typically amber or red, and may appear with or without an accompanying text display. Some cars show a warning symbol alone, while others display a code when scanned.
Common causes of the warning
The warning can be triggered by a range of problems, from electrical faults in the EPS system to fluid or sensor issues. The following list covers typical causes seen in Honda vehicles with EPS or hydraulic power steering.
- Electrical fault in the EPS system (motor, torque sensor, or control module)
- Wiring harness or connector problems in the steering circuit
- Low 12V battery voltage or alternator problem affecting EPS power supply
- Blown fuse/relay related to the power steering circuit
- Hydraulic power steering issues (older Honda models) such as low steering fluid or leaks
- Overheating or mechanical binding in the steering system
- Software/firmware fault or needed ECU/update
In most cases, the root causes are electronic or sensor-related, though a weak electrical supply can also trigger the warning even if steering feels normal at first.
What to do if the warning lights up
Take these steps to stay safe and minimize potential damage to the steering system:
- Drive cautiously and avoid sharp turns or high-speed maneuvers; if possible, pull over to a safe location and stop
- Check for unusual steering feel—stiffness, noise, or delayed response
- Turn the engine off and restart to see if the light clears; if it reappears, do not continue driving long distances
- Check the 12V battery and charging system; a weak battery can cause EPS to behave erratically
- If the light remains on or you notice poor steering assist, contact a Honda dealer or qualified mechanic for diagnosis using the correct diagnostic tools
Note: If you are in a situation where you must continue driving after the restart, keep speeds moderate and avoid dynamic steering maneuvers. Do not rely on manual steering as a long-term solution if the EPS fault persists.
Model differences and maintenance tips
Most newer Honda models use Electric Power Steering (EPS), which is controlled by sensors and a motor powered by the vehicle’s electrical system. Some older models or specific variants may still use hydraulic power steering (HPS) that relies on steering fluid; the warning indicators and behavior can differ between systems.
Diagnosing EPS faults
Honda diagnostics typically require a specialized scan tool to read codes from the EPS control module and sensors. A technician will test voltage levels, inspect the wiring, and verify the EPS motor and torque sensor function, then perform any required software updates or component replacements.
Summary
The power steering warning on a Honda signals a fault in the steering assist system, most commonly the electric power steering. It can result in reduced or lost steering assist, affecting handling and safety. If the light appears, drive cautiously, have the system diagnosed promptly, and seek professional service to restore safe operation.
