Warnings
ℹ️The 2015-2020 Ford F-150 with 3.5L EcoBoost engine is equipped with Electric Power Assisted Steering (EPAS). This system does not use hydraulic power steering fluid and therefore cannot have a power steering fluid flush performed.
⚠If you are experiencing power steering issues, diagnose the electric power steering system using appropriate diagnostic tools. Check for trouble codes related to the steering angle sensor, torque sensor, or EPAS control module.
Preparation
- Verify your vehicle is equipped with EPAS by checking for the absence of a power steering fluid reservoir under the hood
- If power steering concerns exist, connect a diagnostic scan tool to check for EPAS-related fault codes
Procedure
- 1Confirm Electric Power Steering SystemOpen the hood and verify there is no power steering fluid reservoir present. The 3.5L EcoBoost F-150 uses an electric motor mounted on the steering column to provide steering assist, eliminating the need for hydraulic fluid, pump, hoses, and reservoir.
Verification
- No power steering fluid flush is required or possible on this vehicle
- If steering assist issues are present, verify battery voltage is above 12.4V as EPAS performance is voltage-dependent
- Check for diagnostic trouble codes in the power steering control module if steering concerns exist
