Power Steering Pump

This procedure addresses repair of electric power steering components on the 2018-2024 Honda Accord 1.5L Turbo, which uses an electric power steering system with no hydraulic pump or fluid.

Warnings

Tools required

Parts

• EPS (Electric Power Steering) Motor Assembly × 1 — Use OEM specification - Honda Part 53601-TVA-A13 or equivalent
• EPS Mounting Bolts (if corroded) × 2 — M10x1.25 grade 10.9
• Electrical connector dielectric grease × 1 — Honda Shin-Etsu grease or equivalent

Preparation

1. Verify the actual issue requires EPS motor replacement using Honda diagnostic software - many steering issues are sensor or calibration related
2. Park vehicle on level ground and apply parking brake
3. Place wheel chocks behind rear wheels
4. Turn ignition to LOCK position and remove key
5. Disconnect negative battery terminal and wait minimum 3 minutes
6. Raise front of vehicle and support on jack stands at proper lift points
7. Remove both front wheels
8. Take clear photos of electrical connector orientation and routing before disconnection
9. Clear any stored EPS fault codes and document for reference

Procedure

1. 1

   Remove Front Subframe Cross Brace (if equipped)
   Some 2018-2024 Accords have a front subframe cross brace that must be removed for access. Remove the 4 mounting bolts securing the cross brace to the subframe. Set aside for reinstallation.
2. 2

   Access EPS Motor Assembly
   The EPS motor is mounted directly to the steering rack assembly under the vehicle. From underneath, locate the cylindrical EPS motor on the driver's side of the steering rack. Clean area around motor and electrical connector with wire brush to prevent debris from entering system.
3. 3

   Disconnect EPS Electrical Connector
   Locate the main EPS motor electrical connector. Press the locking tab and carefully disconnect the connector from the motor. Inspect connector pins for corrosion or damage. Do not allow connector to hang unsupported - secure to nearby component with wire or tie.
   ⚠Connector pins are gold-plated and delicate. Do not force or pry on pins.
4. 4

   Support Steering Rack
   Place a transmission jack or suitable support under the steering rack assembly to support its weight when the EPS motor is removed. The rack must remain stable and not shift position.
5. 5

   Remove EPS Motor Mounting Bolts
   Locate the 2-3 mounting bolts securing the EPS motor to the steering rack housing. These are typically M10 bolts. Remove bolts in a cross-pattern to prevent binding. Note bolt length and position as they may differ.
   ⚠Motor may be under slight spring pressure from internal gears. Support motor as you remove final bolt.
6. 6

   Remove EPS Motor from Rack
   Carefully pull the EPS motor straight out from the steering rack housing. Internal splines engage with the rack pinion shaft - pull evenly to avoid binding. Once clear, inspect the motor mounting surface and O-ring groove on the rack for damage or debris.
7. 7

   Inspect Rack Pinion Shaft and Housing
   With motor removed, inspect the exposed pinion shaft splines for wear, damage, or metal debris. Check the motor mounting flange on the rack for cracks or distortion. Clean mounting surface thoroughly. If pinion shaft shows damage, rack replacement may be required.
   ⚠Do not rotate steering wheel with EPS motor removed as this may damage internal sensors or cause system faults.
8. 8

   Prepare New EPS Motor
   Remove new EPS motor from packaging. Verify part number matches Honda specification for your specific vehicle VIN. Check that the motor O-ring is properly seated in its groove. Apply small amount of clean Honda DW-1 ATF to O-ring to aid installation (this is for lubrication only - system uses no hydraulic fluid).
9. 9

   Install New EPS Motor
   Align the motor splines with the rack pinion shaft splines. Carefully slide motor onto rack housing, rotating motor shaft slightly to engage splines. Push motor fully onto housing until mounting flanges are flush. Ensure O-ring does not roll or pinch during installation.
10. 10

    Install and Torque Mounting Bolts
    Install EPS motor mounting bolts hand-tight in a cross-pattern. Verify motor is fully seated against rack housing. Torque bolts to specification in a cross-pattern in two stages: first to 50% torque, then to final torque.
    ⚠Over-torquing can distort motor housing and cause binding. Use calibrated torque wrench.
11. 11

    Reconnect Electrical Connector
    Apply thin coat of dielectric grease to connector pins if specified by service manual. Align connector and push firmly until locking tab clicks. Tug gently to verify secure connection. Ensure connector boot is fully seated to prevent moisture intrusion.
12. 12

    Reinstall Front Subframe Brace
    If cross brace was removed, reinstall to subframe and torque mounting bolts to specification. Ensure all fasteners are clean and threads are not damaged.
13. 13

    Reinstall Wheels and Lower Vehicle
    Reinstall front wheels and hand-tighten lug nuts in star pattern. Lower vehicle to ground. Torque wheel lug nuts to specification in star pattern with vehicle weight on wheels.
14. 14

    Reconnect Battery and Perform EPS Calibration
    Reconnect negative battery terminal. Turn ignition to ON position (engine off). The EPS warning light should illuminate then extinguish. Using Honda diagnostic software (HDS or equivalent), perform EPS neutral position calibration and torque sensor zero-point calibration per Honda service procedures. Clear any DTCs that do not return.
    ⚠️EPS calibration is MANDATORY after motor replacement. Failure to calibrate can result in unpredictable steering behavior and loss of vehicle control.
15. 15

    Perform Steering System Verification
    Start engine and verify EPS warning light is off. Turn steering wheel lock-to-lock slowly while stationary - verify smooth operation with no binding, noise, or warning lights. Test drive vehicle at low speed in safe area, checking for proper assist, centering, and no pulling. Recheck for DTCs after test drive.

Reassembly

1. EPS motor calibration must be performed using Honda diagnostic software - this is not optional
2. Verify all electrical connectors are fully seated with locking tabs engaged
3. Ensure no tools or parts were left in engine bay or under vehicle
4. Double-check that steering wheel was not rotated with motor removed, which can cause sensor faults

Verification

• EPS warning light should be OFF with ignition on and engine running
• Steering should provide consistent assist at all speeds with no binding or unusual noises
• Steering wheel should self-center normally when released from a turn
• No diagnostic trouble codes related to EPS system should be present after test drive
• Verify all mounting bolts are torqued to specification and show no signs of looseness
• Electrical connector should be secure with no visible damage or corrosion
• Perform alignment check if vehicle pulls to one side (motor replacement should not affect alignment, but verify)
