Parts for your 2017 Toyota Avensis-Power steering hose

2017 Toyota Avensis and the power-steering-hose question

Short answer: a power-steering-hose isn’t used on the 2017 Toyota Avensis. Technical documentation for the Avensis T27 series (including the 2017 facelift) specifies Electric Power Steering (EPS), not a hydraulic system. This is set out in Toyota’s New Car Features for Avensis T27 and reflected in the 2017 Owner’s Manual steering section, which references EPS operation and warning indicators but provides no power steering fluid checks. Toyota’s Electronic Parts Catalogue for this generation likewise lists no hydraulic pump, reservoir, or power-steering-hose assemblies for the 2015–2018 Avensis.

Why there’s no hose: EPS replaces hydraulic assistance with an electric motor and an ECU linked to the steering column or rack. Because there’s no hydraulic pump, no fluid, and no pressure lines, there’s no need for a power-steering-hose. The setup trims fuel use, removes a common source of leaks, and reduces routine servicing. It also allows more precise steering feel tuning via software.

Seeing references to hoses online and wondering if you’re missing something under the bonnet? That’s usually content aimed at earlier Avensis generations that did run hydraulic power steering. For the 2017 model, if you spot an oily patch around the front end, it’ll be from somewhere else (engine oil, transmission fluid, or split CV/steering rack boots) rather than phantom “power steering fluid”.

• What to check instead: keep tyres at the right pressures, get wheel alignment checked if the steering feels off, and inspect the rack gaiters/boots for splits.
• Electrical health matters: EPS relies on stable voltage, so a tired battery or weak alternator can trigger EPS warnings or heavy steering. Test the battery and charging system during routine servicing.
• Diagnostics: if the EPS light pops up on the dash, a scan for fault codes will point your tech in the right direction. Software updates and calibration procedures are sometimes applicable after component replacement.

Bottom line for the 2017 Avensis: there’s no power-steering-hose to replace, top up, or maintain. Focus servicing on steering joints and boots, alignment, and the vehicle’s electrical health, and the EPS will generally be set-and-forget.

FAQs

Does a 2017 Toyota Avensis have a power-steering-hose?
No. The 2017 Avensis uses Electric Power Steering (EPS), so there’s no hydraulic pump, no fluid, and no hoses to service.

Where do you top up the power steering fluid on a 2017 Avensis?
There’s no reservoir to top up because the system is electric. If you think you’ve found a “power steering fluid” leak, it’s likely another fluid source—have a technician identify it.

What steering maintenance is recommended on the 2017 Avensis?
Check tyre pressures and alignment, inspect rack boots and steering joints, and ensure the battery and alternator are healthy. If the EPS warning light appears, get a diagnostic scan for fault codes.
