Parts for your 2017 Lexus Is-Power steering pump

Understanding the Power Steering Pump on the 2017 Lexus IS

The 2017 Lexus IS is a popular luxury sedan known for its sleek design and sporty performance. When it comes to steering, many car owners wonder if their 2017 Lexus IS uses a traditional power steering pump or if it features a more modern system. After consulting various technical sources and service manuals, it turns out that the 2017 Lexus IS does not use a conventional hydraulic power steering pump. Instead, it employs an Electric Power Steering (EPS) system.

So why does the 2017 Lexus IS not have a traditional power steering pump? The reason lies in the advancements in automotive technology and the push towards more efficient, reliable, and environmentally friendly power steering systems. Traditional hydraulic power steering systems rely on a belt-driven pump that circulates hydraulic fluid to assist with steering effort. Although effective, these systems tend to consume engine power, require regular fluid changes, and have moving parts prone to wear and leaks.

The 2017 Lexus IS swaps this hydraulic setup for an electric power steering system. EPS uses an electric motor to provide steering assistance rather than relying on hydraulic pressure generated by a pump. This system offers several advantages over traditional power steering pumps, including better fuel efficiency, reduced maintenance, and improved steering feel and responsiveness.

With no hydraulic fluid or pump to service or replace, drivers save both time and money. Additionally, since EPS only draws power when steering assistance is needed, it helps with fuel economy and lowers emissions, which aligns with modern vehicle efficiency standards. The electric control allows for more precise calibration tailored to different driving conditions and modes, enhancing the overall driving experience in the Lexus IS.

Since there is no hydraulic power steering pump fitted on the 2017 Lexus IS, the focus on maintenance shifts towards the electronic components associated with the steering system. These include checking the steering rack, electrical connections, and the condition of the EPS motor and sensors. While these parts tend to be highly reliable, it is a good idea to be aware of symptoms like unusual steering effort or noise, which may indicate a need for diagnostic inspection.

Owners looking to keep their 2017 Lexus IS steering system in top shape should consider the following tips:

• Regularly inspect the steering column and mechanical linkages during routine servicing
• Keep an ear out for any clicking or whining noises from the steering system
• Pay attention to any changes in steering feel, heavy effort, or uneven response
• Ensure that the vehicle's battery and electrical system are in good condition, as EPS relies heavily on stable electric power
• Consult the Lexus service manual for any software updates or recalls related to the EPS system

While you don't have to worry about replacing a traditional power steering pump on the 2017 Lexus IS, being proactive with regular maintenance of the electric power steering components promotes longevity and safety. If there is ever an issue requiring repair, it generally involves checking the wiring, sensors, or the motor within the steering rack. Because these parts are typically integrated and more electronically complex than a pump, it's recommended to seek professional diagnostics and repairs from a trusted Lexus technician.

In the end, the move to electric power steering in vehicles like the 2017 Lexus IS reflects the automotive industry's shift towards better efficiency, less maintenance hassle, and improved driving dynamics. Knowing that there is no hydraulic power steering pump means owners can focus on the unique care requirements of EPS to enjoy confident handling and a smooth driving experience year after year.
