How to verify and confirm the issue

Verifying a power steering assist fault on your 2022 Ford Explorer involves a combination of visual checks, basic electrical diagnostics, and potentially using a scan tool.

• Confirm the dashboard message: Ensure the exact "Power Steering Assist Fault" message is displayed.
• Check battery voltage: A weak or failing 12V battery can cause numerous electrical system faults, including power steering issues. Use a multimeter to check the battery's resting voltage (should be around 12.6V) and charging voltage (13.5-14.5V with the engine running).
• Inspect fuses: Locate and inspect the fuses related to the power steering system in both the under-hood and cabin fuse boxes. Consult your owner's manual for specific fuse locations and ratings. A blown fuse can cut power to the Electric Power Steering (EPS) module.
• Visual inspection of wiring and connectors: Look for any signs of damage, corrosion, or loose connections on the wiring harness leading to the steering rack and the EPS control module. Pay close attention to areas exposed to road debris or moisture.
• Scan for diagnostic trouble codes (DTCs): Use an advanced OBD-II scanner to read codes from the Power Steering Control Module (PSCM) and other related modules (e.g., Body Control Module, Powertrain Control Module). Common codes might include U0131 (Lost Communication with Power Steering Control Module), C0051 (Steering Wheel Angle Sensor), or C0000 series codes related to EPS system faults.

• Test drive (with caution): If the steering is only slightly heavy, a brief, cautious test drive might help confirm if the issue is constant or intermittent. However, if steering is severely compromised, avoid driving the vehicle.

Common causes (most likely first)

For the 2022 Ford Explorer, which uses an Electric Power Steering (EPS) system, the causes differ from traditional hydraulic systems:

• Electric Power Steering (EPS) Module Failure: The integrated control module within the steering rack is a common point of failure. This module controls the electric motor that provides assist.
• Low Battery Voltage / Failing Battery: The EPS system is highly sensitive to voltage fluctuations. A weak battery or an alternator not providing sufficient charge can cause the system to fault.
• Wiring Harness or Connector Damage: Frayed wires, corroded pins, or loose connections in the EPS wiring harness can disrupt communication or power supply to the module.
• Steering Angle Sensor (SAS) Malfunction: The SAS, often integrated into the steering column or EPS rack, provides input to the EPS module about the steering wheel's position and rate of turn. A faulty sensor can lead to incorrect assist calculations or system shutdown.
• Steering Rack Motor Failure: While less common than module failure, the electric motor within the rack itself can fail, leading to no assist.
• Software Glitch or Calibration Issue: Sometimes, a temporary software bug or a lost calibration can trigger the fault. This might be resolved with a software update or a recalibration procedure by a Ford dealership.

Step-by-step diagnosis and fixes

Diagnosing and fixing a 2022 Ford Explorer power steering assist fault requires a systematic approach:

1. Start with the basics – battery and fuses:
   • Test your 12V battery. If it's old or failing, replace it. Ensure battery terminals are clean and tight.
   • Check all relevant fuses for the power steering system in both fuse boxes.
2. Scan for DTCs:
   • Connect an OBD-II scanner capable of reading Ford-specific modules. Record all present and historical codes. Using an advanced OBD-II scanner can reveal specific diagnostic trouble codes (DTCs) related to the EPS system. You can learn more about specific codes in our Browse OBD-II codes section.
3. Inspect wiring and connectors:
   • Visually inspect the main power and communication harnesses leading to the EPS rack and module. Look for chafing, cuts, or signs of rodent damage.
   • Carefully disconnect and inspect connectors for corrosion or bent pins. Apply dielectric grease upon reassembly.
4. Check for Technical Service Bulletins (TSBs):
   • Sometimes, Ford releases TSBs addressing known issues with the EPS system. A dealership can check for any applicable TSBs for your specific VIN.
5. Attempt a power cycle/reset:
   • Disconnect the negative battery terminal for 15-30 minutes. This can sometimes clear temporary electronic glitches. Reconnect and retest.
6. Consider steering angle sensor (SAS) recalibration:
   • If codes point to the SAS, or after certain repairs, the SAS may need recalibration using a Ford-specific diagnostic tool.
7. Professional diagnosis:
   • If basic steps don't resolve the issue, it's likely a more complex internal failure of the EPS module, steering rack, or a deeper electrical problem requiring specialized tools and expertise.

• Wiring harness repair: Cost depends on the extent of damage; minor repairs are relatively inexpensive, while full harness replacement can be costly.
• Steering Angle Sensor (SAS) replacement: If the SAS is a separate component, replacement costs for the part and labor can be moderate. If integrated into the steering rack, it becomes part of a larger repair.
• Electric Power Steering (EPS) Rack Replacement: This is often the most significant repair, as the EPS module and motor are typically integrated into the steering rack assembly. The part itself is expensive, and labor involves significant disassembly of the front suspension and steering components. After replacement, the new rack often requires programming and calibration with Ford's diagnostic software.

Cost factors include the price of genuine Ford parts versus aftermarket options, labor rates at independent shops versus dealerships, and the complexity of the diagnosis and required programming.

When to see a professional

Given the safety-critical nature of the steering system, it's highly recommended to consult a professional technician if:

• The basic checks (battery, fuses, visual inspection) do not resolve the issue.
• You are uncomfortable performing electrical diagnostics or working with critical vehicle systems.
• Diagnostic trouble codes point to internal EPS module failure or steering rack issues.
• The repair requires specialized tools, programming, or calibration that only a dealership or a well-equipped independent shop possesses.
