🔧 Pilot - Power Steering “Pump” Clarification & Next Steps
Your Pilot does not use a hydraulic power steering pump. It uses Electric Power Steering (EPS), which means there’s no power steering fluid, no reservoir, and no belt-driven pump to replace.
Before I can give you a correct DIY procedure, I need to confirm what you’re actually replacing (most commonly the EPS steering rack or related electrical parts).
Difficulty Level: Intermediate-Advanced | Estimated Time: 2-6 hours (depends on what’s faulty)
⚠️ Safety & Precautions
- ⚠️ Disconnect the negative battery cable before touching EPS/steering wiring.
- ⚠️ The steering wheel area contains the airbag (SRS); avoid probing yellow SRS connectors.
- ⚠️ Support the vehicle with jack stands on level ground; never rely on a jack alone.
- ⚠️ After steering work, you’ll typically need a front-end alignment.

📋 Before You Begin
- Park on level ground, set the parking brake, and use wheel chocks.
- Center the steering wheel and keep it centered during diagnosis.
- Disconnect the battery using a 10mm socket, then wait at least 3 minutes before working near steering/SRS connectors.
- Have an OBD2 scan tool with Honda EPS capability (specialty) ready to read EPS codes and data.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Confirm there is no hydraulic pump
- Open the hood and look for a power steering fluid reservoir; on your Pilot, you should not find one.
- If a shop told you “pump,” ask them what part number/label they quoted (often they mean the EPS rack).
Step 2: Pull EPS trouble codes (most important step)
- Plug in an OBD2 scan tool with Honda EPS capability (specialty) and scan the EPS/Power Steering system.
- Write down the exact EPS code(s) (example format: “U####” or “C####”) and any freeze-frame data.
- Codes prevent replacing the wrong part.
Step 3: Basic checks that commonly mimic “bad pump” symptoms
- Check battery voltage with a digital multimeter:
- Engine OFF: roughly 12.4–12.7V is typical for a healthy battery.
- Engine ON: charging is typically around 13.5–14.8V.
- Inspect EPS-related connectors/wiring (don’t pull on wires) using a work light and trim clip removal tool as needed.
Step 4: Stop here (I need 2 quick answers to give the correct replacement procedure)
- Are you trying to replace the EPS steering rack, or were you told a different part name?
- What are the exact EPS trouble code(s) you pulled?
✅ After Repair
- If the rack or steering components are replaced, get a 4-wheel alignment.
- Clear EPS codes using an OBD2 scan tool with Honda EPS capability (specialty) and re-check for returning codes after a test drive.
