Parts for your 2007 Toyota Vitz|yaris-Power steering pump

2007 Toyota Vitz/Yaris power steering pump — is it fitted, and what’s actually on the car?

For the 2007 Toyota Vitz/Yaris (XP90 series – commonly coded KSP90/SCP90/NCP9#), a traditional hydraulic power steering pump is not used. Toyota engineered this generation with a column‑assist Electric Power Steering (EPS) system, which delivers steering assist via an electric motor and EPS ECU on the steering column. Because there’s no hydraulic circuit, there’s no power steering pump, no fluid reservoir, no hoses and no steering rack seals associated with a hydraulic setup.

Technical sources that outline this architecture include:

• Toyota New Car Features (NCF) for Vitz/Yaris P9 platform – Steering section describing column‑type EPS with motor, torque sensor and ECU, eliminating a hydraulic pump.
• Toyota Repair Manual (RM) for Yaris/Vitz XP90 – Power Steering (EPS) diagnostics and components, covering the motor/ECU/torque sensor rather than any hydraulic pump or fluid service.
• Toyota Electronic Parts Catalogue (EPC) for 2007 Vitz/Yaris – lists EPS column and related electrical components, with no listing for a power steering pump or fluid reservoir on XP90 models.

Why did Toyota skip the pump on this model? EPS cuts weight and parasitic engine load, improving fuel economy and reducing CO₂. It also frees up space under the bonnet and removes common leak points and fluid maintenance. For owners, that means there’s no power steering fluid to check or replace.

What should owners pay attention to instead? Keep the battery and charging system healthy, because EPS assist depends on stable voltage. If the EPS warning light pops up or the steering feels heavy/intermittent, have the vehicle scanned for EPS fault codes. It’s also worth checking the intermediate shaft/universal joints for play or binding, ensuring the column mounts are tight, and making sure the wheel alignment and tyre pressures are spot on—EPS systems are sensitive to basic geometry and tyre condition. Any clunks, notchy feel around centre, or sudden change in steering effort should be inspected promptly by a technician familiar with Toyota’s EPS checks and calibration procedures.

• Does my 2007 Vitz/Yaris have a power steering pump?
  No. The XP90 Vitz/Yaris uses column‑assist Electric Power Steering, so there’s no hydraulic pump, fluid, hoses or related servicing. Assist comes from an electric motor controlled by the EPS ECU.
• How is steering maintained without a pump?
  Routine maintenance focuses on electrical health (battery/alternator), steering column and intermediate shaft condition, proper wheel alignment and correct tyre pressures. If an EPS warning light appears, a scan tool can retrieve EPS‑specific fault codes for diagnosis.
• What are common EPS symptoms on this model?
  Drivers may notice a warning light, intermittently heavy steering, or a notchy feel near centre. These can stem from low system voltage, a faulty torque sensor, column motor issues, or mechanical play in the shaft joints. Early inspection helps prevent bigger headaches.
