What is the electric power steering warning on a Honda?
The warning indicates a fault in the Honda’s electric power steering (EPS) system and may reduce or cut steering assist. It should be treated as a priority and diagnosed by a qualified technician.
Electric power steering uses an electric motor and sensors to provide steering assistance. When the warning light appears, the EPS control module has detected an abnormal condition—ranging from a transient electrical issue to a genuine hardware fault—so the system may disable or limit assist to protect itself. The exact message on the dash can vary by model and year, sometimes reading “Service EPS” or “Power Steering.”
What the EPS warning means for a Honda
What is Electric Power Steering (EPS)?
EPS is a driver aid that uses an electric motor rather than hydraulic pressure to help you steer. It relies on sensors, the steering column, and the vehicle’s computer to determine how much assist to provide. A fault in any part of this chain can trigger the warning light and, in some cases, reduce or eliminate steering assist.
Dashboard icons and messages
In Honda vehicles, the EPS warning can appear as a light or message such as “Service EPS” or “Power Steering.” The exact appearance depends on the model year and trim. If the light is steady or flashing, or if you notice unusual steering effort, it’s a sign to seek service sooner rather than later.
Common causes
The EPS warning can be triggered by several issues, from temporary electrical glitches to components that need replacement. The most frequent causes are listed below.
- Low or unstable electrical supply from the battery or alternator (voltage dips can fool the EPS controller).
- Faulty EPS motor or torque/steering sensor within the steering column.
- Wiring or connector problems in the steering system, including damaged harnesses or loose connections.
- Steering angle sensor fault or miscalibration in the EPS control module.
- Software or calibration issue in the EPS control unit requiring an update or reinitialization.
If any of these conditions are suspected, the EPS warning should be taken seriously. A dealer or qualified shop can diagnose the fault codes, inspect the hardware, and perform necessary repairs or recalibration.
What to do if the warning lights up
Follow these practical steps to manage safety and move toward a proper diagnosis. The list below outlines a recommended course of action.
- Assess safety and driving conditions: if you feel the steering is significantly harder, slow down and pull over safely. Do not continue aggressive driving with reduced steering assist.
- Check the vehicle’s electrical health: inspect battery terminals for cleanliness and tightness; if the battery is old or the charging system is suspect, address that first since EPS relies on stable voltage.
- Look for other warning lights: the presence of additional warnings can help pinpoint the issue (battery/charging, traction control, etc.).
- Restart the engine: in some cases, a transient glitch clears after a restart, but if the light remains on, treat it as a fault that requires service.
- Use a scan tool if available: retrieve fault codes related to the EPS, steering angle sensor, or related modules to share with a technician.
- Schedule a professional inspection: have a Honda dealer or qualified shop diagnose and repair as needed. Depending on the fault, solutions can range from sensor recalibration to motor or wiring repairs.
Ultimately, EPS issues should be addressed promptly. While you may still be able to drive with the light on, continued operation without proper repair can worsen the fault or lead to unexpected loss of steering assist.
Model-year notes and Honda-specific guidance
Model variations in warnings and procedures
Across Honda models and generations, the wording and icons for EPS warnings can vary. Some cars display “Service EPS,” others show a steering wheel icon, and some may combine the warning with a broader stability or traction message. In all cases, the underlying advice remains the same: diagnose the EPS fault promptly to restore reliable steering assist.
What technicians typically do
Dealers and independent shops usually begin with a diagnostic scan to pull EPS-related codes, then inspect the motor, torque sensor, steering angle sensor, and wiring. Depending on the findings, they may recalibrate sensors, update software, or replace faulty components such as the EPS motor or connectors. After any repair, a reinitialization or alignment of the steering system is often performed to ensure proper calibration.
Summary
The electric power steering warning on a Honda signals a fault in the EPS system, with the potential for reduced or lost steering assist. Treat it as a priority—safely pull over if needed, then have the system diagnosed by a qualified technician. Timely inspection helps prevent unexpected steering issues and ensures the EPS remains reliable across different driving situations.
How to fix electric power steering EPS warning light?
5 seconds. Turn the steering wheel to the full left lock position and apply force for approximately. 5 seconds. Return the steering wheel to the straightforward. Position turn off the ignition.
Can I drive with the electric power steering light on?
Some vehicles may still drive normally with the light on, while others become difficult to steer. Either way, you should have the system checked to avoid worsening the issue.
What does it mean when the electric power steering light comes on?
The electric power steering (EPS) warning light indicates a fault in the power steering system, which could be due to electrical issues like a bad alternator or battery, broken wiring, or a problem with the steering sensors or motor. It could also be a fluid-related issue if your vehicle has a hybrid system. When the light is on, it's crucial to get it checked by a professional as soon as possible, as it can lead to difficulties steering and potential safety risks.

Potential causes
- Electrical problems: A malfunctioning alternator, weak battery, or corroded wiring are common culprits for EPS lights. Other issues could be a bad sensor, a problem with the steering motor, or a glitch in the vehicle's computer system.
- Fluid issues: While less common for EPS, a low power steering fluid level could still be a contributing factor if there's a leak or other related issue.
- Other components: Problems with the serpentine belt or MAF sensor wires can sometimes trigger the warning light.
What to do
- Do not ignore it: Treat the warning light as a sign of a serious problem that needs immediate attention.
- Check for other symptoms: Notice if you experience difficulty steering, especially at low speeds, or if your car pulls to one side.
- Have it diagnosed: It is best to have the car inspected by a professional mechanic to pinpoint the exact cause of the problem. They may need to use a diagnostic computer to identify the issue accurately.
- Consider potential dangers: Continuing to drive with the warning light on can be dangerous, potentially leading to a complete loss of steering assistance or even causing an accident.
How expensive is it to fix electric power steering?
On average, replacing your power steering pump can cost between $500 and $900, but it's essential to avoid more serious damage to the power steering system. Replacing the pump yourself can save you about $300 and significantly lower the total cost of this repair.
