Power Steering Pump on the 2016 Lexus IS: What You Need to Know

The 2016 Lexus IS is a luxury sports sedan that combines performance with refined technology. When it comes to steering, many drivers wonder about the presence and role of the power steering pump, a component commonly found in older vehicles for aiding steering effort. So does the 2016 Lexus IS have a traditional power steering pump? The simple answer is no. Let's explore why this is the case and what it means for owners of this popular Lexus model.

Unlike older cars that use hydraulic power steering systems relying on a dedicated power steering pump, the 2016 Lexus IS employs an Electric Power Steering (EPS) system. Instead of a pump driven by the engine's serpentine belt that pressurises hydraulic fluid to assist steering, EPS uses an electric motor to provide steering assistance. This modern approach changes the way the steering system functions, offering several benefits and altering routine maintenance needs.

The absence of a hydraulic power steering pump in the 2016 Lexus IS means there is no pump to replace or maintain. This is because the EPS system completely eliminates the need for hydraulic fluid, power steering hoses, or a pump. Instead, the electric motor and its control electronics adjust steering effort based on vehicle speed and driver input, making steering lighter at low speeds and firmer at high speeds. This tech-savvy system makes life easier for drivers and mechanics alike.

Electric Power Steering has been embraced across many modern vehicles due to its advantages over traditional hydraulic setups. Firstly, it improves fuel efficiency. Without a pump dragged by the engine belt constantly running, the engine doesn't have to use extra power to spin the pump. That means a small boost to fuel economy. This setup also reduces maintenance costs and complexity, no need to check or replace power steering fluid, no risk of fluid leaks, and no belt-driven parts that can wear out.

For the 2016 Lexus IS driver, this means the steering system is generally very reliable and low maintenance. However, it does not mean it is completely maintenance-free. The EPS system relies on sensors, an electric motor, and a control module. If these parts suffer malfunction due to wear, electrical issues, or impacts, steering assistance can fail or behave inconsistently. In those cases, diagnostics and component replacement might be necessary - tasks typically handled by a qualified Lexus technician.

So what should a 2016 Lexus IS owner keep in mind when it comes to keeping their steering system in good shape?

1. Regular Servicing: While the EPS system itself does not need fluid changes or pump repairs, routine vehicle servicing should include steering system checks. This can involve verifying the condition of the electric motor, wiring, and sensors, ensuring connectors are clean and secure, and watching for diagnostic trouble codes related to steering.
2. Address Warning Lights Promptly: If the EPS warning lamp appears on the dashboard, it's a sign that the system has detected a fault. Ignoring this could lead to loss of steering assistance, which could be dangerous. Prompt diagnostics and repairs can keep the car safe and handling smoothly.
3. Avoid Physical Damage: The EPS components are electronic and sensitive to impact and extreme conditions. Avoiding collisions to the steering column or severe jolts helps protect the system. Similarly, when fitting aftermarket accessories or working on the engine bay, care should be taken not to damage wiring or connectors related to the electric power steering unit.
4. Software Updates and Calibration: Occasionally, Lexus may release software updates designed to improve EPS performance or fix known issues. Ensuring the vehicle's systems are up to date by visiting authorised service centres helps keep steering responsive and reliable.

Because of the EPS system, the idea of replacing a power steering pump in the 2016 Lexus IS is obsolete. Traditional issues such as pump noise, leaks, or belt wear do not apply. Instead, the focus is on electrical diagnostics and maintaining the control systems. This modern steering technology aligns with Lexus' reputation for blending luxury and innovation in their vehicles.

To sum up, the 2016 Lexus IS does not use a power steering pump. It opts for an advanced electric power steering system that offers better efficiency, reduced maintenance, and responsive steering effort. For owners, that means no worries about pump replacements or fluid flushes, but it does mean staying attentive to warning lights and keeping up with recommended servicing for electronic components. With proper care, the EPS system on the 2016 Lexus IS provides smooth and precise steering for a confident driving experience.
