Typically there is no user-initiated reset switch for the Ford Explorer's electric power steering. The system relearns after power cycling or a brief drive, and persistent warnings usually require dealer-level diagnostics.
Understanding EPAS and why a reset might be needed
Electric Power Assisted Steering (EPAS) in modern Ford Explorers uses an electric motor, a steering angle sensor, and a control module to provide variable steering assist. If the system detects a fault or the battery voltage is unstable, it can trigger warning lights such as the EPS (Electric Power Steering) or Steering Assist fault. In many cases, the system self-corrects after a power cycle or normal driving, but some faults require professional diagnosis and calibration with Ford's diagnostic tools.
DIY checks you can perform at home
Before attempting any reset, inspect these common causes that are safe to check on your own:
- Ensure the 12-volt battery is healthy and fully charged; EPAS depends on stable electrical power.
- Check fuses labeled EPS or Power Steering in both interior and engine bay fuse boxes.
- Inspect tires for proper inflation and ensure wheel alignment is correct, as misalignment can affect steering feel and trigger warnings.
- Use an OBD-II scanner to look for codes related to steering, SAS (Steering Angle Sensor), or EPS.
- Observe dash warnings: if the EPS light is on or steering feels abnormal, avoid aggressive driving and seek professional service.
If these checks reveal faults or no improvement after basic steps, relying on the system could be unsafe and you should seek service from a qualified technician.
Soft reset attempts you can try safely
These steps are non-invasive and aim to retrain the steering angle sensor and EPAS in some vehicles. They may clear transient faults after power or sensor reinitialization.
- With the engine off, park on level ground and engage the parking brake.
- Turn the ignition to ON without starting the engine and wait a few seconds for the system to initialize.
- Gently turn the steering wheel from full left to full right, repeating 2–3 cycles while the ignition is ON but the engine is not running.
- Return the wheel to center, then start the engine and drive slowly in a safe area for several minutes, performing light steering maneuvers at moderate speeds to aid relearning.
- If the warning persists after these steps, stop and seek professional service.
A soft reset can help with transient faults or post-battery work, but persistent issues usually require dealer diagnostics and possible component replacement.
When to seek dealership service or Ford diagnostic tools
Some EPAS recalibrations require Ford's factory tools or dealer guidance. If your Explorer shows any of these signs, avoid risky driving and contact a dealer as soon as possible:
- Steering feels heavy, inconsistent, or the EPS light is illuminated.
- Loss of power assist during driving or the wheel won’t return to center after turns.
- OBD-II codes related to Steering Angle Sensor, EPS, or Torque Sensor.
- Recent work on the steering column, battery replacement, or significant electrical repairs.
In such cases, a technician with Ford IDS/diagnostic tools can perform a proper calibration, verify sensor alignment, and update software if needed.
Summary
Resetting the electric power steering on a Ford Explorer isn’t typically a simple user-activated process. In many situations, the system re-learns after a proper power cycle or a careful, short drive. If warnings persist, professional diagnostics are required to pinpoint sensor or control-module faults and to perform precise recalibrations with the appropriate tools. Always prioritize safety and consult a Ford dealer or qualified shop for a definitive fix.
