Parts for your 2010 Mitsubishi Lancer-Power steering pump

2010 Mitsubishi Lancer power-steering pump: is it even there?

For most 2010 Mitsubishi Lancer models (the common CJ-series sedans and hatches sold in Australia and New Zealand), a hydraulic power-steering pump isn’t fitted or required. Mitsubishi’s own technical literature confirms this: the CJ/CF Workshop Manual details Electric Power Steering (EPS) on the steering column, and the 2010 Owner’s Manual omits any power‑steering fluid checks because there’s no fluid reservoir. The Mitsubishi ASA electronic parts catalogue also lists no hydraulic pump or hoses for standard CJ Lancer variants, the belt‑driven hydraulic system appears only on the high‑performance Evolution X (CZ4A) and some Ralliart models.

Why no pump? Because the Lancer’s EPS uses an electric motor and control unit to assist the steering, doing away with hydraulic lines, a pulley‑driven pump, and power‑steering fluid. That brings a few wins for everyday owners: fewer leaks and less mess, a small bump in fuel economy (no belt drag on the engine), quieter operation, and easier integration with safety systems like stability control and lane‑sensing features where fitted.

What does that mean for servicing? There’s no power‑steering fluid to top up, no pump to rebuild, and no hoses to replace due to seepage. Instead, good care focuses on keeping the EPS healthy and the rest of the steering and charging system in top nick.

• Electrical system: EPS is sensitive to low voltage. A tired battery or weak alternator can trigger a steering warning light or heavier steering feel. Test the battery and charging system, especially before long trips.
• Steering hardware: Even with EPS, mechanical bits still wear. Check front wheel alignment, inspect inner and outer tie‑rod ends, and make sure the intermediate steering shaft and column joints are free of play.
• Diagnostics: If the EPS warning lamp comes on, scan the vehicle with a capable tool. Common procedures include checking the torque sensor, verifying the steering angle sensor calibration, and confirming EPS control unit grounds and connectors.
• Don’t add fluid: There’s no power‑steering fluid reservoir on standard CJ Lancers. If a shop suggests a “power‑steering flush,” it doesn’t apply to these models.

Note for performance models: The Evolution X (and some Ralliart variants) uses a conventional hydraulic pump. Those owners should follow the workshop manual for fluid spec, belt condition, pump noise checks, and hose inspections.

Popular questions

Does a 2010 Mitsubishi Lancer have a power‑steering pump or fluid?
Most 2010 Lancer CJ models sold in AU/NZ use Electric Power Steering, so there’s no hydraulic pump and no fluid reservoir to service. If it’s an Evolution X (CZ4A) or certain Ralliart versions, it will have a belt‑driven hydraulic pump—check the VIN and under‑bonnet layout to confirm.

What maintenance does the Lancer’s EPS actually need?
There’s no fluid service. Keep the battery and alternator healthy, ensure clean connectors at the EPS module, and inspect tyres, alignment, and steering joints. If the EPS light appears or the steering feels odd, have it scanned and carry out sensor calibrations as required.

My steering feels heavy sometimes—should I replace a pump?
On EPS‑equipped CJ Lancers there’s no pump to replace. Intermittent heaviness is often related to low system voltage, poor grounds, or a sensor calibration issue. Rule out a weak battery or charging fault first, then check for EPS fault codes and mechanical steering wear.
