Understanding the 2013 Ford F-150 Power Steering Assist Fault
The 2013 Ford F-150 utilizes an Electric Power Assist Steering (EPAS) system, a departure from traditional hydraulic power steering. This system uses an electric motor and sensors instead of a pump and fluid to provide steering assistance. While more efficient, it also introduces a unique set of potential failure points.
When you see the “Power Steering Assist Fault” message, it means the EPAS control module has detected an issue preventing it from providing proper steering assistance. This could range from a minor sensor glitch to a major component failure. Understanding the EPAS system’s components is the first step in diagnosing the problem.
Key Components of the EPAS System
The EPAS system in your F-150 relies on several critical parts working in harmony. A failure in any of these can trigger the power steering assist fault.
Steering Rack Assembly: This is the core component, housing the electric motor, torque sensor, and the EPAS control module. It’s often the most expensive part to replace. Torque Sensor: Located within the steering rack, this sensor measures the effort you apply to the steering wheel, signaling the motor to provide the appropriate assistance. EPAS Control Module (PSCM): This module acts as the brain, receiving input from various sensors (like the torque sensor, speed sensor, and battery voltage) and controlling the electric motor.
Wiring Harness and Connectors: The electrical connections are crucial for communication between the module, motor, and other vehicle systems. Corrosion or damage here can easily cause faults. Battery and Charging System: The EPAS system draws significant power. A weak battery or failing alternator can lead to insufficient voltage, triggering a fault.
Common Symptoms and Diagnostic Steps
When your 2013 F-150 throws a power steering assist fault, the most obvious symptom is a sudden increase in steering effort. However, other signs can point to the specific nature of the problem.
Recognizing the Symptoms
It’s important to note all symptoms you’re experiencing. This information can be very helpful for diagnosis.
- Heavy Steering: The steering wheel becomes very difficult to turn, especially at low speeds or when stationary.
- “Power Steering Assist Fault” Message: This warning appears on your instrument cluster.
- Warning Lights: Other dashboard warning lights, such as the battery light or ABS light, might illuminate. This often points to a wider electrical issue.
- Intermittent Loss of Assist: Steering might feel normal sometimes, then suddenly become heavy, indicating a sporadic electrical fault or overheating component.
- Noises: Unusual grinding, whining, or clunking sounds from the steering column or front end can indicate mechanical failure.
Initial Checks for the DIYer
Before reaching for your diagnostic scanner, perform some basic visual checks. These simple steps can sometimes reveal an obvious culprit.
- Check Battery and Alternator: Ensure your battery terminals are clean and tight. A low battery voltage can often trigger EPAS faults. Test your battery’s charge and the alternator’s output if possible.
- Inspect Fuses: Locate the fuse box (usually under the hood and/or inside the cabin) and check the fuses related to the power steering system. Consult your owner’s manual for exact locations and ratings.
- Look for Visible Damage: Inspect the wiring harness leading to the steering rack for any signs of fraying, cuts, or corrosion. Check for fluid leaks (though less likely with EPAS, it’s good practice).

Advanced Diagnostics: Using an OBD-II Scanner
For a precise diagnosis of the 2013 Ford F-150 power steering assist fault, an OBD-II scanner capable of reading manufacturer-specific codes is essential. Basic scanners might only show generic P-codes, but you need U-codes (network communication) and C-codes (chassis-related) for EPAS issues.
Retrieving Diagnostic Trouble Codes (DTCs)
Connect your OBD-II scanner to the diagnostic port (usually under the dashboard on the driver’s side). Follow the scanner’s instructions to read the stored codes.
Common EPAS-related DTCs you might encounter:
- U0100: Lost Communication with ECM/PCM A (Engine Control Module/Powertrain Control Module)
- U0131: Lost Communication with Power Steering Control Module (PSCM)
- C1277: Torque Sensor Malfunction
- C1299: Steering Angle Sensor Malfunction
- C2002: Steering Assist Motor Stuck ON
- C2005: Steering Assist Motor Circuit Open
- C200D: Power Steering Control Module Internal Fault
Each code provides a clue. For example, a U-code often points to a communication issue, while a C-code usually indicates a specific component fault within the EPAS system.
Interpreting and Troubleshooting DTCs
Once you have the codes, research their specific meaning for your 2013 F-150. Many online resources and service manuals provide detailed diagnostic trees for each code.
For communication codes (U-codes), check:
- Wiring harness integrity (look for breaks, corrosion, loose connections).
- Fuse for the PSCM.
- Power and ground supply to the PSCM using a multimeter.
For component-specific codes (C-codes), this typically points to a failure of that particular part. However, always verify wiring to the component before assuming the component itself is faulty.
Common Causes and Repair Solutions
Identifying the root cause of a 2013 Ford F-150 power steering assist fault can save you time and money. Here are the most frequent culprits and their associated fixes.
1. Faulty Electric Power Steering (EPS) Rack
