Parts for your 2017 Toyota Crown-Power steering hose

2017 Toyota Crown power-steering hose — is it relevant?

Short answer: it isn’t. On the 2017 Toyota Crown (S210 series – including ARS210, GRS210/214 and AWS210 hybrid grades), a hydraulic power-steering hose is not used because the car runs Electric Power Steering (EPS), not a hydraulic system.

Technical references back this up. Toyota’s New Car Features (NCF) documentation for the 210 Series describes a rack-parallel type Electric Power Steering system, which uses an electric motor on the steering rack and no hydraulic pump, reservoir, pressure line or return line. Likewise, the Toyota Electronic Parts Catalogue (Steering, Group 44) lists an EPS rack assembly and associated electrical components for these models, with no power-steering hoses or fluid-related items for the 2015–2018 Crown range.

Because it’s EPS, there’s no power-steering fluid to top up and no pressure/return hoses to leak. That’s by design: EPS removes the belt-driven pump, cutting parasitic drag, improving fuel economy and reducing maintenance. It also lets the Crown integrate steering assist with safety and driver-assist features (like lane-keeping support and variable assist by speed) in a way that’s trickier with hydraulics.

What should a Crown owner or workshop focus on instead?

• Inspect the steering rack boots and tie-rod ends for wear, play or damage.
• Check for EPS warning lights and scan for steering ECU fault codes if the steering feels heavy or notchy.
• Verify 12V battery health and charging voltage, low system voltage can reduce EPS assist.
• Confirm wheel alignment, tyre pressures and front suspension bush condition, as these affect steering feel.
• Apply any relevant ECU calibration updates per Toyota service information.

Note: Some older Toyota taxi-based models (e.g., Crown Comfort) used hydraulic systems with hoses, but that doesn’t apply to the 2017 Crown S210 passenger range.

Popular questions about the 2017 Toyota Crown power-steering hose

Does a 2017 Toyota Crown have a power-steering hose?
No. The 2017 Crown uses Electric Power Steering with an electric rack-and-pinion unit, so there’s no hydraulic hose, pump, reservoir or fluid to service.

Why does my 2017 Crown feel heavy to steer if there’s no power-steering fluid?
EPS relies on good battery voltage and healthy sensors. Heavy steering can come from a weak 12V battery, charging issues, a steering torque sensor fault, or a problem in the EPS motor/ECU. Also check tyre pressures, wheel alignment and front-end wear.

Can I convert the EPS to a hydraulic setup or add fluid?
No practical conversion is available or recommended. The steering system is engineered as EPS from the factory, and there’s no provision for hoses or fluid-based assist.
