The warning typically signals a fault in the power steering system, most often the Electric Power Steering (EPS) system found in modern Hondas. When the light is on, you may experience reduced or no steering assist and should seek service promptly.
Honda’s EPS system relies on sensors, an electric motor, and control software to provide variable steering assist. A fault can stem from electrical issues, sensor or motor failures, or a low-voltage condition from the battery or charging system. Depending on the fault, the system may still operate at higher speeds or disable assist to protect itself, so understanding and addressing the warning quickly is important for safe driving.
What the light looks like and how it behaves
Symptoms you might notice
Common indicators include a steering wheel icon on the dashboard with an exclamation mark, noticeably heavier steering effort at low speeds, a whine or groan from the steering rack, or intermittent loss of assist. The light can appear alone or alongside other warnings like the battery light or check engine light.
- EPS motor or torque/angle sensor failure
- Low battery voltage or failing alternator (voltage dips can trigger EPS faults)
- Damaged wiring, loose connectors, or corroded grounds in the EPS circuit
- Blown fuse or faulty relay in the power steering/EPS circuit
- Software/ECU fault or outdated firmware
- For older hydraulic systems: low power steering fluid, leaks, or worn drive belt
Because EPS is electronically controlled, the exact behavior can vary by model year. If the light persists, do not ignore it and arrange a professional check.
Common causes
Several issues can trigger the warning light. Being aware of the most frequent culprits helps you understand why a diagnostic check is necessary.
- Faulty EPS motor or steering angle/torque sensor
- Low voltage from the battery or a failing alternator
- Damaged wiring, loose connectors, or corroded grounds in the EPS circuit
- Blown fuse or faulty relay in the EPS/power steering circuit
- Software or control module fault requiring an update or reset
- For older Hondas with hydraulic assist: low power steering fluid, leaks, or a worn belt
These issues can compromise steering reliability. Prompt diagnosis helps ensure safe operation and prevents further damage to the steering system.
What to do if the light comes on
Take safe, deliberate action when the warning appears. The steps below guide you through a prudent response.
- Safely pull over and park as soon as practicable; turn off the engine, then restart to see if the light clears
- Check for other warning lights and note any unusual steering feel, vibrations, or noises
- If the battery is weak or the charging system is underperforming, have the electrical system inspected; EPS faults can be voltage-related
- If the light remains on or you notice heavy steering, avoid high-speed driving or long trips; arrange towing or roadside assistance if needed
- Schedule service with a Honda dealer or qualified shop to diagnose EPS components, wiring, fuses, and the battery/charging system; a software update may be issued by Honda
In short, the warning indicates a fault in the steering system that could affect safety. Driving with a persistent EPS fault can increase the risk of sudden steering loss, so seek professional diagnosis promptly.
What to expect at the dealership
At a service visit, technicians will typically verify battery health, perform a comprehensive EPS test, inspect wiring and grounds, retrieve fault codes from the EPS control module, and conduct a road test. Depending on the diagnosis, repairs may include replacing the EPS motor or sensor, repairing wiring, replacing fuses/relays, or applying a software update. Costs vary by model year and the exact fault.
Summary
The Honda power steering warning light signals a fault in the EPS (or, in older hydraulics, the hydraulic system) that can reduce or cut steering assist. If the light comes on, respond safely by pulling over, checking for additional warnings, and arranging prompt professional diagnosis. Regular electrical system maintenance and timely attention to warning lights help maintain steering reliability and overall vehicle safety.
