Steps

🔧Does this apply to your car? After replacing an electric power steering module, most vehicles require a steering angle sensor calibration (and often module coding) with a capable scan tool. Skipping calibration can cause pull, lane-keep faults, or stability-control warnings.

✓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 covers the removal and replacement of the Electric Power Steering (EPS) control module on the 2012-2017 Toyota Camry with 2.5L I4 engine.

Warnings

⚠Disconnecting the battery will erase radio presets and may require window auto-up/down recalibration

⚠The EPS module contains sensitive electronics - avoid dropping or exposing to moisture

ℹ️A steering wheel position calibration may be required after module replacement using a scan tool

Parts

Electric Power Steering Control Module × 1 — Use OEM specification
Dielectric grease × 1 — Electrical connector grease

Preparation

Park vehicle on level surface and set parking brake
Turn ignition off and remove key
Open hood and locate battery in engine compartment
Disconnect negative battery cable and wait 3 minutes for airbag system to discharge
Locate the EPS module mounted on the steering column under the dashboard on driver side

Procedure

1
Remove lower dash panel
Remove the lower dashboard trim panel below the steering column. Remove the retaining screws and carefully pull the panel away from the dash to release the clips. Set panel aside.
2
Access steering column area
If necessary, remove the knee airbag panel or additional trim pieces to gain clear access to the steering column and EPS module. The module is typically mounted on the side or bottom of the steering column assembly.
⚠Handle airbag components carefully and store face-up in a safe location away from work area
3
Disconnect EPS module electrical connectors
Locate the main electrical connector(s) on the EPS control module. Press the locking tab and carefully disconnect each connector from the module. Note the connector positions and routing for reinstallation.
4
Remove EPS module mounting hardware
Remove the mounting bolts securing the EPS module to the steering column bracket. Support the module as you remove the final fastener to prevent it from falling.
Torque spec
Mounting Bolts27 Nm (20 lb-ft)
5
Remove EPS control module
Carefully remove the EPS module from the vehicle. Note the orientation and any grounding straps or additional connections. Inspect the mounting bracket and connectors for damage or corrosion.
6
Prepare new EPS module
Unpack the new EPS control module. Verify part number matches the original module. Inspect electrical connector pins for damage and apply a small amount of dielectric grease to connector terminals to prevent corrosion.
7
Install new EPS module
Position the new EPS module onto the steering column bracket in the correct orientation. Start all mounting bolts by hand to ensure proper thread engagement before tightening.
8
Torque mounting bolts
Using a torque wrench, tighten the EPS module mounting bolts to specification in a cross pattern to ensure even pressure.
Torque spec
Mounting Bolts27 Nm (20 lb-ft)
9
Reconnect electrical connectors
Reconnect all electrical connectors to the EPS module. Ensure each connector clicks securely into place and locking tabs are fully engaged. Verify proper routing of wiring harnesses.
10
Reinstall interior trim
Reinstall the knee airbag panel (if removed), lower dash panel, and all other trim pieces in reverse order of removal. Ensure all clips are properly seated and screws are tightened securely.
11
Reconnect battery
Reconnect the negative battery cable. Do not start the vehicle yet - allow the EPS system to perform initial power-up diagnostics for 30 seconds.

Reassembly

Ensure all electrical connectors are fully seated with locking tabs engaged
Verify all interior trim panels are properly secured with no gaps or loose clips
Reset power windows by fully lowering and raising each window while holding the switch for 2 seconds at full up position

Verification

Turn ignition to ON position without starting engine - verify EPS warning light illuminates then extinguishes after 3-5 seconds
Start engine and verify no EPS warning lights remain on the dashboard
Turn steering wheel lock to lock while stationary - verify smooth operation with no unusual noises or resistance
Test drive vehicle at low speed in safe area to confirm proper power steering assist function
If EPS warning light remains on or steering feels abnormal, perform steering angle sensor calibration using appropriate scan tool
Scan for diagnostic trouble codes - address any EPS-related codes before returning vehicle to service
