Steps

✓Expert-verified. Personally reviewed and approved by OLP's master technicians (Chris Hackleman & Jeff Moore — 20+ years each). Always follow the vehicle's factory service information and torque specs.

This procedure cannot be performed as specified because the 2018-2024 Honda Accord 1.5L Turbo uses an Electric Power Steering (EPS) system with no hydraulic fluid to flush.

Warnings

ℹ️The 2018-2024 Honda Accord 1.5L Turbo is equipped with Electric Power Steering (EPS), which uses an electric motor instead of hydraulic fluid. There is no power steering fluid to flush on this vehicle.

⚠If you are experiencing power steering issues, diagnose the EPS system using proper scan tools to check for fault codes, motor failure, or torque sensor problems.

Preparation

Verify the vehicle actually has Electric Power Steering by checking under the hood - there will be no power steering fluid reservoir
If power steering concerns exist, connect a Honda diagnostic scanner to check for EPS-related trouble codes

Procedure

1
Confirm Electric Power Steering System
Open the hood and visually confirm there is no power steering fluid reservoir. The EPS system on this vehicle integrates the electric motor directly with the steering column and requires no hydraulic fluid. If a reservoir is present, verify the vehicle identification as this procedure is specifically for the 1.5L turbo model which uses EPS exclusively.
2
Inspect EPS Components (If Diagnosing Issues)
If investigating power steering concerns, check the EPS fuse in the under-hood fuse box, inspect wiring harness connections to the EPS motor on the steering column, and verify battery voltage is adequate (minimum 12.4V with engine off). Low voltage can cause EPS malfunctions.
3
EPS System Diagnostics
Use a Honda-compatible diagnostic scanner to retrieve any stored or pending EPS fault codes. Common codes include issues with the torque sensor, motor malfunction, or communication errors. EPS system problems require electronic diagnosis rather than fluid service.

Reassembly

No disassembly or reassembly required for this vehicle as it has no hydraulic power steering system

Verification

Confirm the vehicle has Electric Power Steering by the absence of any power steering fluid reservoir under the hood
If diagnosing steering concerns, verify proper EPS operation by starting the engine and turning the steering wheel - it should provide smooth assisted turning with no warning lights on the instrument cluster
