Parts for your 2015 Mitsubishi Lancer-Power steering pump

2015 Mitsubishi Lancer power-steering-pump: what’s fitted and what’s not

For the 2015 Mitsubishi Lancer sold in Australia and New Zealand (CJ/CF series, non‑Evolution models), there’s no hydraulic power‑steering pump on board. These cars use a column‑assist Electric Power Steering (EPS) setup, so there’s no belt‑driven pump, no power‑steering fluid, and no lines or reservoir to service. The notable exception is the Lancer Evolution X (CZ4A), which retains a conventional hydraulic rack with a belt‑driven power‑steering pump.

Technical references behind this call:

• Mitsubishi Motors Workshop Manual (Lancer CJ/CF), Group 37A – Power Steering: details a column‑assist EPS system with no hydraulic pump.
• Mitsubishi ASA electronic parts catalogue (AU/NZ): no power‑steering pump listed for CJ/CF non‑Evolution models, pump and associated hydraulics listed for Evolution X (CZ4A).
• Mitsubishi Lancer Evolution X (CZ4A) Workshop Manual, Group 37 – Power Steering: specifies a belt‑driven hydraulic pump and hydraulic rack.

Why the regular 2015 Lancer doesn’t use a power‑steering pump:

• Efficiency and economy: EPS draws power only when assistance is needed, trimming fuel use and emissions compared with a constantly spinning hydraulic pump.
• Less maintenance: no fluid to change, no hoses to seep, and no pump bearings or seals to fail.
• Better control tuning: assistance can be mapped by the ECU for speed‑sensitive feel and stability control integration.
• Packaging and reliability: fewer belt‑driven ancillaries under the bonnet and less chance of leaks.

Servicing tips for owners of a 2015 Lancer with EPS:

• No power‑steering fluid service is required. If someone’s trying to sell a “power‑steering flush” on a non‑Evolution Lancer, that’s not applicable.
• Keep the battery and charging system healthy. EPS relies on clean voltage, a weak battery can make the steering feel heavy or trigger the EPS warning lamp.
• At regular services, have the steering column joints, rack boots and front suspension bushes inspected, and get a wheel alignment if tyres show uneven wear.
• If the EPS light comes on or the wheel goes heavy intermittently, a scan for steering ECU fault codes and a check of the torque sensor/clock spring wiring is the next step.

If the vehicle in question is actually a 2015 Lancer Evolution X, then yes, it uses a hydraulic power‑steering pump. In that case, keep an ear out for pump whine, inspect the drive belt, check for fluid leaks at hoses and the rack, and renew the specified fluid at intervals recommended by the workshop manual or if it’s contaminated.

Popular questions about the 2015 Mitsubishi Lancer power‑steering pump

Does a 2015 Mitsubishi Lancer have a power‑steering pump?
For the standard 2015 Lancer (CJ/CF, non‑Evolution), no. It uses electric power steering, so there’s no hydraulic pump or fluid. The Evolution X (CZ4A) is the exception and does have a belt‑driven hydraulic pump.

How do I service the steering on my 2015 Lancer if there’s no pump?
Stick to basics: keep the battery strong, rotate and align tyres, and have the steering column joints and rack boots inspected at service time. If the EPS warning light appears or the steering feels odd, get a diagnostic scan for EPS fault codes.

What should I check if my steering feels heavy on a non‑Evolution Lancer?
Start with battery/charging voltage, then tyre pressures and alignment. If the issue persists, a technician can check the EPS torque sensor, steering ECU and related wiring. There’s no fluid level to top up on EPS‑equipped models.
