Parts for your 2017 Toyota Vitz|yaris-Power steering pump

2017 Toyota Vitz/Yaris power-steering pump: is it fitted, and what’s actually used?

The 2017 Toyota Vitz/Yaris (XP130 series – KSP130/NSP130/NCP131) does not use a hydraulic power-steering pump. Instead, it runs an Electric Power Steering (EPS) system with a motor and ECU mounted to the steering column. That means there’s no belt-driven pump, no power-steering fluid, and no hydraulic hoses on this model year hatch.

Technical sources backing this up:

• Toyota Repair Manual (RM) for Yaris/Vitz XP130: Power Steering section identifies “Electric Power Steering (Column Assist Type)” with a motor, torque sensor and Power Steering ECU, and provides EPS diagnostics (DTCs such as C15xx). No hydraulic pump procedures are listed.
• Toyota New Car Features (NCF), XP130 series: Details EPS architecture and components, describing motor-driven assist and speed‑sensitive control.
• 2017 Yaris/Vitz Owner’s Manual: Mentions electric power steering and omits any power-steering fluid checks or service items, consistent with EPS.
• Toyota Electronic Parts Catalogue (EPC) for 2017 XP130: Lists the EPS column assembly and related electrical components, no power-steering pump, reservoir or pressure hoses are catalogued for these VIN ranges.

Why a pump isn’t used on the 2017 Vitz/Yaris:

• Efficiency: No parasitic drag from a belt-driven pump, helping fuel economy and emissions.
• Packaging and weight: EPS is lighter and frees up space in the engine bay.
• Better tuning: Variable assist by vehicle speed and steering input improves feel and stability on Kiwi and Aussie roads.
• Lower upkeep: No hydraulic fluid to leak, flush, or top up, fewer moving parts to wear.
• Diagnostics: The EPS ECU monitors itself and logs fault codes, making issues easier to pinpoint.

For owners chasing a “power-steering pump” on a 2017 Vitz/Yaris, there simply isn’t one to service or replace. If steering feels heavy or inconsistent, the usual culprits are EPS-related: low 12‑volt battery voltage, poor alternator output, a steering torque sensor fault, or wiring/connectors at the column. The dash EPS warning lamp is a giveaway—scan for codes, check battery/charging health, confirm tyre pressures and alignment, and have a technician perform any required EPS calibration or software updates. Routine servicing is straightforward: keep tyres at spec, inspect the intermediate shaft for play or noise, and ensure the electrical grounds are clean and tight. That’s it—no fluid, no pump, no worries.

• Popular questions

Does the 2017 Toyota Vitz/Yaris have a power-steering pump?
No. It uses a column‑assist Electric Power Steering system, so there’s no hydraulic pump, reservoir or hoses fitted from factory.

What maintenance does the EPS need on a 2017 Vitz/Yaris?
There’s no fluid service. Keep the 12‑volt battery and charging system healthy, maintain correct tyre pressures and wheel alignment, and have a workshop check for EPS fault codes if the warning light appears. Inspect the steering column/intermediate shaft for play during routine servicing.

Steering feels heavy sometimes—what should be checked first?
Start with battery voltage and alternator output, then scan the EPS for trouble codes. Check fuses, column motor connectors, and tyre pressures. If the EPS light is on, don’t ignore it—get a technician to diagnose and recalibrate the system if needed.
