Parts for your 2023 Mitsubishi Asx-Power steering pump

2023 Mitsubishi ASX power‑steering pump: what’s actually fitted

Short answer: a traditional power‑steering pump isn’t used on the 2023 Mitsubishi ASX. Technical documentation lists Electric Power Steering (EPS), which replaces the old hydraulic pump-and-hoses setup. The 2023 ASX Owner’s Manual for Australia/NZ specifies EPS and notes there’s no power‑steering fluid to check. Likewise, the Mitsubishi genuine parts catalogue for the 2023 ASX shows an electric assist motor on the steering column/rack with no hydraulic pump, lines, or reservoir. European 2023 ASX specifications (for the Captur-based model) also list electric power steering. Across these sources, there’s no provision for a hydraulic pump on this model year.

Why no pump? The ASX’s EPS uses an electric motor and control unit to provide steering assist, so it doesn’t need a belt-driven hydraulic pump or fluid. That’s great news for day‑to‑day ownership and servicing.

• Efficiency and responsiveness: Without an engine‑driven pump, there’s less parasitic load, which helps fuel economy and keeps assist consistent regardless of engine speed.
• Lower maintenance: No power‑steering fluid, no hoses, no pump bearings or seals to leak. One less fluid service to worry about.
• Packaging and noise: Fewer components under the bonnet and less pump whine—cleaner layout and quieter operation.
• Smarts on board: EPS plays nicely with driver‑assist tech and stability control because the control unit can fine‑tune assist on the fly.

For owners used to hydraulic systems, there’s nothing to top up and no pump to replace on a 2023 ASX. If the steering ever feels heavy or inconsistent, think EPS basics: correct tyre pressures, battery and charging system health (low voltage can upset EPS), no damage to steering rack boots, and no warning light for the EPS system. After suspension or alignment work, a steering angle sensor calibration may be required—any competent workshop with the right scan tool can handle that. If a fault code is logged, technicians will diagnose the EPS motor, torque sensor or control unit rather than chasing a non‑existent pump or fluid leak.

This page focuses on the ASX built and sold for 2023 in Australia and New Zealand. The takeaway is the same across the line‑up: it’s EPS, not hydraulic—so there’s no power‑steering pump to service on the 2023 Mitsubishi ASX.

• Does the 2023 Mitsubishi ASX have a power‑steering pump?
  No. The 2023 ASX uses Electric Power Steering (EPS), which provides assist via an electric motor and controller, so there’s no hydraulic pump, lines, or reservoir fitted.
• Where do you check the power‑steering fluid on a 2023 ASX?
  There isn’t any. Because the ASX runs EPS, there’s no hydraulic fluid to check or replace. If steering feels heavy, look to tyre pressures, wheel alignment, battery/charging health, or an EPS fault light.
• Can a hydraulic power‑steering pump be retrofitted to a 2023 ASX?
  It’s not practical or recommended. The car is engineered for EPS—retrofitting a hydraulic system would require major changes and could affect safety compliance and insurance.
