🔧 Power Steering Pump - Not Equipped

Your Yaris does not use a hydraulic power steering pump. It uses electric power steering, so there is no pump, fluid, hose, or belt-driven power steering unit to replace. If you have lost steering assist, the problem is usually in the EPS system, steering rack/motor, fuse, wiring, or battery/charging system.

Difficulty Level: Intermediate | Estimated Time: 1-3 hours for diagnosis

• Do not try to add power steering fluid; this system is not hydraulic.
• Disconnect the negative battery cable before unplugging EPS connectors.
• Keep hands clear of the steering shaft and rack while testing.
• If the steering wheel feels stiff or the EPS light is on, do not drive far until diagnosed.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm the system type

• Open the hood and inspect the engine bay. There should be no power steering reservoir, pump, or hydraulic hoses.
• If you see no fluid system, this confirms EPS, not a pump.

Step 2: Check for EPS faults

• Use an OBD-II scan tool to read codes from the power steering control system.
• Record any codes before clearing them.

Step 3: Check battery and charging voltage

• Use a digital multimeter to check battery voltage.
• Look for low voltage, loose terminals, or corrosion.
• Low voltage can disable steering assist.

Step 4: Inspect fuses and wiring

• Use the fuse box cover diagram and remove the EPS-related fuse with a trim panel tool or your fingers if accessible.
• Inspect the fuse for damage and check connectors for looseness or corrosion.

Step 5: Replace the steering rack only if confirmed bad

• If diagnostics point to the rack/motor assembly, remove the front under covers and disconnect the EPS harness.
• Unbolt the rack and replace it as an assembly.
• Torque fasteners to factory spec for the rack, shaft, and subframe connections.

Step 6: Clear codes and road test

• Reconnect the battery.
• Use the OBD-II scan tool to clear EPS codes.
• Start the car and verify steering assist is normal.

✅ After Repair
