Determining whether your car has electric steering, also known as Electric Power Steering (EPS), can be done through a few simple checks. Unlike traditional hydraulic systems, EPS relies on an electric motor to assist with steering, making it more energy-efficient and easier to maintain. To identify if your car has electric steering, start by checking your vehicle’s owner’s manual, as it will explicitly state the type of steering system installed. Additionally, you can inspect the engine bay for the absence of a hydraulic pump or reservoir, which are common in hydraulic systems. Another telltale sign is the presence of a warning light on the dashboard labeled EPS or Power Steering that illuminates if there’s an issue with the electric system. Finally, electric steering often provides a lighter, more responsive feel at low speeds and may include features like variable steering assist, which adjusts based on driving conditions.

What You'll Learn
Check for Electric Power Steering (EPS) Badge
One of the simplest ways to determine if your car has electric power steering (EPS) is to look for a badge or emblem on the vehicle’s exterior or interior. Automakers often use badges to highlight key features, and EPS is no exception. Start by inspecting the steering wheel, dashboard, or the lower part of the front doors for a badge labeled "EPS," "Electric Power Steering," or a similar variation. These badges are typically small, discreet, and designed to blend with the car’s aesthetics, so you may need to look closely. If you spot one, it’s a clear indicator that your car is equipped with electric steering.
However, the absence of a badge doesn’t necessarily mean your car lacks EPS. Some manufacturers omit badges for design or marketing reasons, especially in newer models where electric steering is standard. In such cases, consulting your vehicle’s owner’s manual is the next best step. The manual often includes a section detailing the car’s steering system, confirming whether it’s hydraulic, electric, or hybrid. If you’ve misplaced the manual, most automakers offer digital versions on their websites, searchable by your car’s make, model, and year.
For those who prefer a hands-on approach, a quick test can provide insight. Turn the ignition to the "on" position (without starting the engine) and listen for a faint humming or whirring sound near the steering column. Unlike hydraulic systems, which rely on a pump, EPS systems use an electric motor that often emits a subtle noise when activated. Additionally, try turning the steering wheel with the engine off. If it feels lighter and more responsive than a traditional system, it’s likely electric. However, this method isn’t foolproof, as some EPS systems are designed to mimic the feel of hydraulic steering.
If you’re still unsure, consider the age and model of your car. Electric power steering became widespread in the mid-2000s, so vehicles manufactured after 2010 are highly likely to have EPS, especially compact and midsize cars. Luxury or performance vehicles may retain hydraulic systems for their precise feedback, but this is increasingly rare. Cross-referencing your car’s production year with industry trends can provide additional context, though it’s always best to verify with a badge or manual.
In conclusion, checking for an EPS badge is a quick and effective first step in identifying electric power steering. While it’s not definitive, combining this method with manual consultation or a simple diagnostic test can provide clarity. Understanding your car’s steering system isn’t just a matter of curiosity—it can also help you anticipate maintenance needs and driving characteristics, ensuring a smoother and safer experience on the road.

Inspect Steering Column for EPS Components
The steering column is a treasure trove of clues when identifying Electric Power Steering (EPS) systems. Unlike hydraulic systems, EPS relies on electronic components nestled within this central shaft. A visual inspection here can reveal telltale signs of its presence.
Look for a compact electric motor, often cylindrical or rectangular, mounted directly onto the steering column. This motor is the heart of the EPS system, providing assistive torque based on driving conditions. Surrounding the motor, you might find a wiring harness – a bundle of cables connecting the motor to the vehicle's electrical system and control module.
Inspection Steps:
- Locate the Steering Column: Begin by identifying the steering column, the vertical shaft connecting the steering wheel to the steering gear. It's typically covered by a plastic shroud for protection and aesthetics.
- Remove the Shroud: Carefully pry off the shroud panels using a trim removal tool or flathead screwdriver. Be gentle to avoid damaging clips or fasteners.
- Examine for EPS Components: With the shroud removed, visually inspect the steering column for the electric motor and wiring harness. The motor's size and shape can vary depending on the vehicle make and model.
- Check for Sensors: EPS systems often incorporate sensors to monitor steering wheel position and torque. Look for small, cylindrical sensors mounted near the motor or on the steering shaft itself.
Caution: Avoid touching any exposed electrical components or attempting to disconnect wires unless you're a qualified mechanic.
Takeaway: A visual inspection of the steering column is a straightforward way to identify EPS components. The presence of an electric motor and associated wiring is a strong indicator of an EPS system. If you're unsure, consult your vehicle's owner's manual or seek professional assistance.

Test Steering Effort at Low Speeds
Steering effort at low speeds is a telling indicator of whether your car employs electric power steering (EPS) or a hydraulic system. At parking lot velocities—typically under 10 mph—EPS-equipped vehicles exhibit a lighter, almost effortless feel when turning the wheel. This is because electric motors provide assistance that’s proportional to speed, maximizing support when you need it most: during tight maneuvers. In contrast, hydraulic systems, which rely on engine-driven pumps, may feel slightly heavier at low speeds due to their constant pressure output. To test this, find an empty lot and perform a slow, deliberate turn. If the wheel responds with minimal resistance, EPS is likely at play.
However, not all light steering effort at low speeds confirms EPS. Some modern hydraulic systems incorporate speed-sensitive valves to mimic the behavior of electric steering, making them feel similarly agile. To differentiate, pay attention to the feedback. EPS often delivers a more muted, disconnected feel from the road, while hydraulic systems retain a tactile sense of tire-to-pavement contact. If your car’s steering feels light but still communicates surface textures, it might be a sophisticated hydraulic setup rather than electric.
For a more definitive test, observe the steering effort during engine-off maneuvers. In an EPS-equipped car, you can typically start the engine, shift to drive, and turn the wheel with the engine off—the electric motor will still provide assistance via the battery. In a hydraulic system, turning the wheel with the engine off will feel significantly heavier, as the power steering pump requires engine power to function. This simple experiment can quickly reveal the underlying technology.
If you’re still unsure, consider the vehicle’s age and design. Most cars manufactured after 2010 are likely to have EPS, as it’s more fuel-efficient and easier to integrate with advanced driver-assistance systems (ADAS). Older models, particularly those from the 1990s and early 2000s, predominantly use hydraulic systems. Cross-reference your observations with the car’s production year and model specifications for added clarity.
In conclusion, testing steering effort at low speeds is a practical, hands-on method to identify electric power steering. Combine this with feedback analysis, engine-off testing, and contextual knowledge of your vehicle’s design to make an informed determination. While not foolproof, this approach provides a clear starting point for understanding your car’s steering system.

If you’ve never noticed this symbol before, it’s worth familiarizing yourself with your dashboard’s layout to spot it easily.
To effectively use this method, start your car and observe the dashboard during the initial system check. All warning lights should briefly illuminate as part of the routine diagnostic process. If the EPS light appears during this check and then turns off, it confirms your car has electric steering. However, if the light remains on while driving or flashes intermittently, it indicates a potential issue with the EPS system, requiring immediate attention. Ignoring this warning can lead to steering difficulties or complete failure, compromising safety.
A practical tip is to consult your vehicle’s owner’s manual for a precise description of the EPS warning light and its location. Different manufacturers may use slightly varying designs, and the manual often includes troubleshooting steps if the light activates unexpectedly. For instance, some manuals suggest restarting the vehicle or checking the battery voltage, as electrical issues can sometimes trigger false warnings. If the light persists, professional diagnosis is essential to avoid further damage.
Comparatively, older vehicles with hydraulic power steering lack this warning light, as their systems rely on mechanical components rather than electronic sensors. This distinction makes the EPS light a modern diagnostic tool unique to electric steering systems. By leveraging this feature, drivers can not only confirm the presence of EPS but also monitor its health proactively. Regularly checking for this light during routine inspections can help catch issues early, ensuring optimal steering performance and safety.
