Parts for your 2018 Toyota Wish-Power steering pump

2018 Toyota Wish Power‑Steering Pump — Is It Fitted?

Short answer: a 2018 Toyota Wish doesn’t use a traditional hydraulic power‑steering pump. The second‑generation Wish (ZGE20/25 series), which ran up to 2017 production with many cars first registered in 2018, uses Electric Power Steering (EPS). This is documented in Toyota service literature (TIS repair manual for ZGE2#), the owner’s manual steering section, and Toyota parts catalogues that list an EPS column/motor and ECU rather than a hydraulic pump, hoses or fluid reservoir. Independent spec sheets for the 2009–2017 Wish also note EPS as standard across the range.

Why there’s no pump on this model: EPS provides steering assist via an electric motor on the column or rack, governed by a steering ECU using inputs from a torque sensor and vehicle speed. Because the assist is electric, there’s no belt‑driven pump, no power‑steering fluid, no hoses, and no steering‑specific pulleys. That means less parasitic drag, fewer leaks, better fuel economy, and simpler servicing – ideal for everyday Kiwi and Aussie driving.

What owners should focus on instead:

• Battery and charging health – low system voltage can make EPS feel heavy or intermittent.
• Wheel alignment and tyre condition/pressures – can mimic heavy steering.
• Steering column and rack inspection – check for play at the intermediate shaft U‑joints and rack ends.
• Diagnostics if the EPS warning lamp appears – scan for EPS DTCs (e.g., torque sensor, motor, or ECU faults) using proper equipment.

Things you won’t need on a Wish with EPS:

• No power‑steering fluid flushes or top‑ups.
• No pump belt adjustments or pump seal replacements.
• No hose or reservoir maintenance specific to hydraulic systems.

If steering effort increases or there’s a warning light, it’s worth having a qualified technician run an EPS system check, confirm battery/alternator output, and perform a wheel/tyre and suspension inspection. Using genuine‑quality parts and following Toyota’s diagnostic roadmap from the ZGE2# repair manual will save time and guesswork.

• Does a 2018 Toyota Wish have a power‑steering pump?
  No. It uses Electric Power Steering, so there’s an electric motor and control unit instead of a hydraulic pump and fluid.
• Where’s the power‑steering fluid reservoir on a 2018 Wish?
  There isn’t one. EPS doesn’t use hydraulic fluid, so you won’t find a reservoir, hoses, or a pump on this model.
• Why does my Wish’s steering feel heavy sometimes?
  Common causes include low battery/charging voltage, incorrect tyre pressures or alignment, or an EPS system fault. If the EPS light is on, get the codes scanned and checked by a technician familiar with Toyota EPS.
