Parts for your 2016 Mitsubishi Asx-Power steering pump

2016 Mitsubishi ASX Power-Steering Pump — Is It Fitted?

For the 2016 Mitsubishi ASX sold in Australia and New Zealand (and most global markets), a traditional hydraulic power-steering pump is not fitted. This model uses a column‑type Electric Power Steering (EPS) system driven by an electric motor and controlled by an EPS ECU, so there’s no hydraulic pump, reservoir, fluid lines or belt to worry about.

Technical sources confirming EPS and the absence of a hydraulic pump include:

• Mitsubishi Motors Workshop Manual (ASX/RVR/Outlander Sport, 2015–2017): Steering section specifies Electric Power Steering (column assist) with EPS‑ECU and motor, not a hydraulic system.
• MMC ASA electronic parts catalogue for 2016 ASX (GA2W/GA3W/GA4W): Steering parts listings show EPS column/motor/ECU and no power‑steering pump, reservoir, or high‑pressure hoses.
• Owner’s Manual (2016 ASX): No scheduled service item for power‑steering fluid, consistent with EPS.
• Trade data services (e.g., Autodata/Mitchell1/ALLDATA): Identify EPS on 2016 ASX models, with diagnostic procedures for the EPS control unit rather than hydraulic components.

Why Mitsubishi doesn’t use a pump on this ASX:

• Efficiency and fuel economy: EPS only draws power when assistance is needed, unlike a belt‑driven hydraulic pump that’s always spinning.
• Lower maintenance: No fluid changes, no leaks, no pump bearings or drive belts to service.
• Packaging and reliability: Fewer hoses and seals, cleaner engine bay, and easier integration with stability control and lane systems.

What owners should expect instead: if steering ever feels heavy or the EPS warning light pops up, the usual checks are battery health and charging voltage (low voltage can upset EPS), wheel alignment and tyre condition, and a scan for EPS fault codes. Any odd noises or notchiness are more likely from the column, intermediate shaft, or front suspension components rather than a non‑existent pump. A routine service for a 2016 ASX won’t include power‑steering fluid top‑ups because there isn’t any.

• Does the 2016 Mitsubishi ASX have a power‑steering pump?
  No. It uses Electric Power Steering (EPS) with an electric motor on the steering column, so there’s no hydraulic pump, reservoir, or fluid.
• What steering maintenance does a 2016 ASX need?
  Keep the battery and charging system in good nick, check steering and suspension joints, and have alignment set correctly. If the EPS light shows, get the codes read and tested by a tech.
• Can a hydraulic pump be fitted to replace the EPS?
  Not practically. Converting to hydraulic would require major redesign of steering, wiring, brackets and plumbing. If assistance feels weak, diagnose the EPS rather than trying to retrofit a pump.
