Parts for your 2019 Mitsubishi Asx-Power steering pump

2019 Mitsubishi ASX power-steering-pump: what’s fitted and what isn’t

The 2019 Mitsubishi ASX does not use a traditional hydraulic power-steering pump. Instead, it’s fitted with electric power steering (EPS), where an electric motor provides steering assist and a control unit manages assistance based on speed and steering input. This means there’s no belt-driven hydraulic pump, no power-steering fluid, and no associated hoses or reservoir on this model.

Technical sources backing this: the 2019 Mitsubishi ASX Owner’s Manual (AU/NZ) lists Electric Power Steering under the steering system, Mitsubishi Motors Service Manual (Group 37A – Steering) details EPS architecture rather than hydraulic assist, and the Mitsubishi ASA electronic parts catalogue for 2019 ASX variants (including GA/GM series) shows no hydraulic pump assembly or fluid circuit for the steering system.

Why the pump isn’t used on the 2019 ASX comes down to the advantages of EPS. It reduces engine load, trims fuel consumption, and simplifies servicing by removing fluid changes and leak-prone hardware. It also allows finer tuning of steering feel and integrates neatly with driver-assist systems.

• Lower maintenance: no fluid to top up, no pump belt, no hoses to leak.
• Efficiency: no constant parasitic drag on the engine.
• Smarter control: assist can vary with speed and driving mode.

For owners and workshops, steering-related care on a 2019 ASX focuses on EPS health rather than a pump. Smart maintenance includes checking the condition of the steering rack boots, ensuring wheel alignment is on point, keeping the 12 V battery and charging system healthy (low voltage can upset EPS), and scanning for steering control unit fault codes if the EPS warning light appears or steering effort feels inconsistent. After suspension or steering work, a steering angle sensor calibration may be required with a scan tool. If heavier-than-normal steering crops up intermittently, voltage drop testing and earth checks are worth a look before suspecting the EPS motor or rack.

Popular questions

Does the 2019 Mitsubishi ASX have a power steering pump?
No. The 2019 ASX uses electric power steering (EPS), so there’s no hydraulic pump, no fluid reservoir, and no hoses. Assist is provided by an electric motor managed by the EPS control unit.

Does a 2019 ASX need power-steering fluid top-ups?
No. Because it’s an EPS system, there’s no hydraulic fluid to check or replace for the steering. If fluid is seen near the steering rack, it will be something else (for example, engine oil or transmission fluid) and should be identified before repairs.

What steering maintenance makes sense on a 2019 ASX?
Keep the battery and charging system healthy, check rack boots and front-end components for wear, and ensure wheel alignment is correct. If the EPS warning light shows or steering gets unusually heavy, a diagnostic scan can point to voltage, sensor, or motor issues.
