Warnings

⚠The 2015-2020 Ford F-150 with 5.0L V8 Coyote engine is equipped with Electric Power Assisted Steering (EPAS). This system does not use hydraulic power steering fluid and cannot have a fluid flush performed.

ℹ️If you are experiencing power steering issues, diagnose the EPAS system using a compatible scan tool. Common failures include the steering column control module, torque sensor, or electric motor assembly.

ℹ️Some early 2015 F-150 models with different engine configurations may have used hydraulic power steering. Verify your specific vehicle has EPAS before attempting any repair procedure.

Preparation

Verify the vehicle is equipped with Electric Power Assisted Steering (EPAS) by checking for the absence of a power steering fluid reservoir in the engine bay
If power steering concerns exist, connect a Ford IDS or compatible scan tool to retrieve EPAS diagnostic trouble codes

Procedure

1
Confirm EPAS System
Open the hood and visually confirm there is no power steering fluid reservoir on the driver's side of the engine compartment. The EPAS system is fully electric and mounted in the steering column.
2
Alternative Service
If steering performance issues are present, perform EPAS system diagnostics using Ford IDS or equivalent scan tool. Check for codes related to steering angle sensor, torque sensor calibration, or motor circuit faults.

Reassembly

No disassembly or reassembly required for this procedure

Verification

Confirm with the vehicle owner that the 2015-2020 F-150 with 5.0L V8 uses electric power steering with no hydraulic fluid
If steering concerns exist, verify proper EPAS operation through scan tool data and road test
