Parts for your 2018 Toyota Vitz|yaris-Power steering pump

2018 Toyota Vitz/Yaris power-steering pump — is it there, and does it matter?

For the 2018 Toyota Vitz/Yaris, a traditional hydraulic power-steering pump isn’t fitted. This model uses a column‑assist Electric Power Steering (EPS) system, which provides steering assist via an electric motor mounted on the steering column, not a belt‑driven hydraulic pump. That means there’s no power‑steering fluid, no pump, and no hydraulic hoses to service under the bonnet.

Technical sources back this up: the Toyota Owner’s Manual for the 2018 Yaris describes an Electric Power Steering system with a steering warning light but makes no mention of hydraulic fluid or a pump in routine maintenance. Toyota’s Repair Manual (Power Steering System [EPS] – System Description) for the XP13#/XP15# Yaris/Vitz platform specifies a column‑type EPS with a motor, ECU and torque sensor. Toyota’s New Car Features (NCF) materials for Vitz/Yaris of this generation likewise outline a column‑assist EPS configuration. Across global variants of the 2018 Vitz/Yaris (including the hatch and the Mazda‑derived Yaris iA sedan), EPS is standard.

Why no power‑steering pump on this model? Because EPS delivers the same helpful steering assist without the hydraulic complexity. It’s lighter, more efficient, and needs less maintenance—ideal for everyday city runs and longer Kiwi and Aussie kilometres alike.

• Efficiency: No engine‑driven pump dragging on the belt, so there’s a small fuel‑economy gain.
• Maintenance: No fluid to flush, no pump seals to leak, and fewer moving parts to wear.
• Packaging: Cleaner engine bay with fewer hoses and pulleys.
• Smarts: The EPS ECU can vary assist by speed and driving conditions, and it can store diagnostic trouble codes if something’s off.

What should owners do instead of “pump” servicing? Keep the 12‑volt battery and charging system healthy—low voltage can reduce steering assist. Have the steering and suspension inspected during regular servicing (rack boots, tie‑rods, ball joints), keep tyres correctly inflated, and get a wheel alignment if it pulls. If the EPS warning light pops up, a technician can scan the EPS ECU for fault codes and perform calibrations (e.g., torque sensor or steering angle) if required. If someone offers a power‑steering fluid flush on a 2018 Vitz/Yaris, it’s not applicable to this car.

Popular questions about 2018 Toyota Vitz/Yaris power‑steering pump

Where is the power‑steering pump on a 2018 Vitz/Yaris?
It doesn’t have one. This model uses electric power steering, so there’s no belt‑driven pump or fluid reservoir under the bonnet. Steering assist comes from an electric motor on the steering column, controlled by the EPS ECU.

Does a 2018 Vitz/Yaris need power‑steering fluid?
No. There’s no hydraulic system to top up. If a workshop suggests a power‑steering fluid change on this vehicle, they’re mixing it up with older hydraulic setups. Any groaning or heavy steering should be diagnosed as EPS‑related or checked for low battery voltage, tyre issues, or alignment problems.

What steering maintenance actually matters on this model?
Focus on battery condition, charging voltage, tyre pressures, and routine checks of tie‑rod ends and rack boots. If the EPS warning light illuminates, have a technician scan the system and carry out any required calibrations. A wheel alignment after suspension work or kerb strikes will keep it tracking straight.
