Parts for your 2018 Mitsubishi Asx-Power steering pump

2018 Mitsubishi ASX power-steering pump: what’s actually fitted

For the 2018 Mitsubishi ASX, a traditional hydraulic power‑steering pump isn’t used. Technical sources list the ASX/Outlander Sport/RVR of this era as running a column‑type Electric Power Steering (EPS) system. The Mitsubishi service manual’s Power Steering section for these model years identifies “Electric Power Steering (EPS)” rather than a hydraulic setup, the 2018 Outlander Sport owner’s manual notes the vehicle is equipped with EPS and does not require steering fluid checks, and Mitsubishi Australia/New Zealand specification sheets for MY18 ASX list “Electric power assisted rack and pinion” steering. Put simply, a pump is not relevant to this vehicle.

Why no pump? EPS replaces the engine‑driven hydraulic pump, hoses and fluid with an electric motor and control unit. That means less parasitic load on the engine (better fuel use), no power‑steering fluid to leak or change, and fewer moving parts to service. It also gives smarter, speed‑sensitive assist and helps packaging under the bonnet.

So if someone’s hunting a “2018 Mitsubishi ASX power‑steering pump”, they’re looking for a part the car doesn’t have. What matters for steering health on an EPS‑equipped ASX is electrical and mechanical condition, not hydraulic components.

• Common EPS care tips for the 2018 ASX:
  • Keep the battery and charging system in top nick. Low voltage can trigger EPS warnings or heavy steering.
  • Maintain correct tyre pressures and get wheel alignments as needed to keep steering effort light and consistent.
  • During servicing, have the steering column, intermediate shaft, rack ends and front suspension bushes checked for play or binding.
  • If the EPS light comes on or steering feels notchy, have a technician scan the EPS module for fault codes and inspect the column motor/torque sensor.

Popular questions

Does the 2018 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, no belts, and no power‑steering fluid to top up.

What steering maintenance does a 2018 ASX need if there’s no pump?
Focus on the basics: good battery/alternator health, correct tyre pressures, regular wheel alignments, and inspections of the steering column joints, rack ends and suspension bushes. If the EPS warning light appears or the steering feels heavy, get the system scanned for fault codes.

Why do some parts sites list a power‑steering pump for this model?
Many catalogues are generic across model families and years. The 2018 ASX specifically uses EPS, so hydraulic pump listings are usually miscategorised or meant for other vehicles that still use hydraulic assist.
