Understanding the Power Steering Pump in the 2020 Nissan Pathfinder

For those interested in the 2020 Nissan Pathfinder and its steering system, the power steering pump plays an important role in many vehicles with hydraulic power steering. However, when it comes to the 2020 Nissan Pathfinder, things are a bit different. This model does not actually use a traditional power steering pump, and here's why.

The 2020 Nissan Pathfinder is equipped with an Electric Power Steering (EPS) system rather than the older hydraulic power steering setup that utilises a power steering pump. The shift to EPS is part of a broader automotive trend where manufacturers move towards more efficient, reliable, and easier-to-maintain steering systems.

Hydraulic power steering systems use a power steering pump that is driven by the engine's accessory belt. This pump generates hydraulic pressure to assist the driver in turning the steering wheel. The pump circulates power steering fluid through hoses to a steering gear, which makes steering effort easier, especially at low speeds. This system requires regular maintenance such as checking fluid levels, inspecting hoses for leaks, and occasionally replacing the pump or fluid to maintain performance.

Electric Power Steering systems like the one in the 2020 Nissan Pathfinder, on the other hand, do away with the hydraulic pump completely. Instead, an electric motor provides the assist, which is controlled by the vehicle's computer and sensors that measure steering input and speed. This electric setup means no power steering fluid, no belts driving a pump, and less mechanical complexity overall.

So why does Nissan use EPS in the Pathfinder? For starters, EPS has several advantages:

• Improved fuel efficiency, as the electric motor only works when steering assist is needed, unlike a pump that runs constantly with the engine
• Reduced maintenance, since there are no fluids to check or leaks to worry about
• Enhanced steering feel and adaptability, with the ability to adjust steering effort based on speed and driving conditions
• Lower environmental impact due to no power steering fluid disposal and lower energy consumption

With that in mind, if you're servicing a 2020 Nissan Pathfinder, you won't find a power steering pump to replace or maintain. Instead, maintenance will focus on the EPS components, which can include checking the steering column and electronic connections, as well as updating software as needed during scheduled services.

Although there's no need to worry about hydraulic fluid leaks or power steering pump wear, it is still important to pay attention to the steering system's overall performance. Pay attention if the steering feels unusually heavy or if warning lights related to stability and steering appear on your dashboard, as these can indicate an issue with the electric power steering system.

In the event of EPS failure, repairs usually involve diagnosing electrical faults with specialised scan tools and replacing faulty sensors or the EPS motor itself. This tends to be less frequent than hydraulic power steering pump failures, however, repairs can be a bit more technical because of the electronic components involved.

If you want to keep your steering system in tip-top shape, regular inspections during your Nissan Pathfinder's service appointments will ensure everything functions properly. The electric power steering motor and related parts generally have a long service life, but software updates and basic electrical diagnostics can help prevent minor issues from becoming costly repairs.

To wrap it up, the absence of a power steering pump in the 2020 Nissan Pathfinder is a sign of Nissan embracing modern technology that delivers better efficiency, easier maintenance, and improved driving experience. While traditional power steering pumps still work well in many older and some current models, the EPS system in the Pathfinder offers a smoother, simpler, and more eco-friendly alternative that suits today's drivers better.
