Power Steering Service

This procedure explains how to inspect and diagnose the electric power steering system on a 2018-2024 Honda Accord with the 1.5L turbo engine, which uses an electric power steering system that requires no fluid service.

Warnings

Tools required

Preparation

1. Park vehicle on level ground and engage parking brake
2. Turn ignition off and remove key
3. Ensure steering wheel is in the centered position
4. Allow electric power steering system to fully power down (wait 2 minutes after ignition off)

Procedure

1. 1

   Verify Electric Power Steering System
   Confirm that this vehicle is equipped with Electric Power Steering (EPS) by checking for the absence of a power steering fluid reservoir under the hood. The 1.5L turbo Accord uses an electric motor mounted on the steering column, not a hydraulic pump.
2. 2

   Check for Diagnostic Trouble Codes
   Connect the HDS or OBD-II scanner to the vehicle's diagnostic port located below the driver's side dashboard. Turn ignition to ON position without starting the engine. Check for any EPS-related diagnostic trouble codes in the EPS control module.
3. 3

   Inspect EPS Motor and Connections
   Open the hood and visually inspect the EPS motor mounted on the steering column under the dashboard. Check the electrical connector for corrosion, damage, or loose connections. Inspect wiring harness for chafing or damage.
4. 4

   Test Steering Operation
   Start the engine and verify that the EPS warning light on the instrument cluster is not illuminated. Turn the steering wheel slowly from lock to lock while stationary, listening for any unusual noises such as grinding, clicking, or whining from the EPS motor.
5. 5

   Perform Road Test
   Drive the vehicle at various speeds and verify smooth power steering assist. Check for proper steering return to center, no excessive play in the steering wheel, and no unusual vibrations or resistance. Verify power assist is consistent at all speeds.
6. 6

   Check Steering Angle Sensor Calibration
   Using the HDS or compatible scanner, verify that the steering angle sensor is properly calibrated and reading correctly. If the steering wheel was recently removed or alignment was performed, perform steering angle sensor neutral position learning procedure per Honda service manual.

Reassembly

1. No disassembly or reassembly required for this inspection procedure
2. If any electrical connectors were disconnected during inspection, ensure they are fully seated and locked

Verification

• Verify no EPS warning lights are illuminated on the instrument cluster
• Confirm smooth power steering assist at idle and during driving
• Verify no diagnostic trouble codes are present in the EPS system
• Confirm steering wheel returns to center properly after turns
