Can I drive with the electric power steering light on?
Yes, you can usually continue driving, but you will likely lose some or all steering assist, making the steering noticeably heavier. Treat the warning seriously, plan to get the vehicle inspected as soon as possible, and avoid long trips if the road/traffic conditions demand easy steering.
Electric power steering (EPS) uses a motor and sensors controlled by a vehicle’s computer to provide steering assist. When a fault is detected, the system may reduce or disable assist to protect components and alert the driver with a warning light. The behavior can vary by make and model, so consult your owner’s manual for specifics.
What the EPS light indicates
The EPS warning light signals an issue in the electric steering system. Possible problems include a faulty steering angle sensor, motor or wiring fault, a blown fuse, battery or power supply issue, or software glitches in the control module. In some cases, the car may enter a safe or reduced-assist mode to keep steering functional, but with noticeable changes in effort required to turn the wheel.
Common causes
The following list summarizes typical triggers for the EPS light. The items are not exhaustive and vary by vehicle.
- Faulty steering angle or position sensor
- EPS motor or wiring fault
- Blown fuse or weak/fluctuating battery voltage
- Software or calibration issue in the steering control module
- Water intrusion or corrosion in connectors
Understanding these potential causes helps drivers know why the warning appeared and why professional diagnosis is important. The EPS system is integral to steering feel and safety, so addressing faults promptly reduces risk during driving.
Can I drive with the EPS light on?
In most cases, you can still drive with the EPS light on, but you should expect reduced steering assist or possibly none at all, depending on the fault. Heavy steering is common at low speeds, and steering effort increases, which can be tiring and may affect precision in tight maneuvers. If you notice abnormal steering behavior, plan to stop and seek service soon. Do not rely on the system to function normally for tasks that require quick or precise steering.
Immediate steps if you encounter the EPS warning on the road
Use this checklist to stay safe and minimize risk when EPS light appears while driving.
- Find a safe place to pull over and stop as soon as possible, especially if steering feels unpredictable.
- Check for other warning lights on the dashboard (battery, ABS, check engine) that might indicate additional issues.
- If traffic and conditions allow, drive slowly and avoid sudden or sharp steering inputs.
- Call roadside assistance if you are unsure about the fault or if the light remains on after starting the engine.
- Do not repeatedly restart the vehicle in an attempt to reset the system; if the light persists, seek professional help.
The goal is to reduce risk while transporting the vehicle to a qualified repair facility. Some drivers may choose to proceed to a nearby service center for a diagnostic check if conditions are safe, but long trips or high-speed driving is discouraged while the EPS light is on.
What you can do to prevent EPS faults
Regular maintenance and a few precautions can help minimize EPS warnings and prolong steering system health. The following list outlines practical steps, followed by a short recap.
- Keep the vehicle’s battery and electrical system healthy; EPS relies on stable voltage.
- Check fuses and wiring related to the steering system if you notice warning lights.
- Ensure software updates for the steering control module are installed as recommended by the manufacturer.
- Avoid exposure to water or contaminants that could affect sensors and connectors.
- Have the EPS calibrated or inspected during routine service, especially after steering or handling complaints.
Proactive maintenance helps catch sensor or motor drift before it triggers a warning light in daily driving.
When to seek immediate professional help
If the EPS light appears alongside unusual noises, a hard-to-turn steering wheel, or a complete loss of steering assist at any time, stop safely and arrange for transport to a service center. Any loss of steering capability can present a serious safety risk, particularly at higher speeds or in heavy traffic.
Summary
The EPS light signals a fault in the electric power steering system. While many vehicles can still be driven with reduced or no assist, driving with the warning should be limited and timed with urgent service. Plan a diagnostic check promptly, and in the meantime drive cautiously, avoid aggressive steering maneuvers, and seek roadside assistance if the issue worsens or safety feels compromised.
