Ever turned your steering wheel only to find it suddenly feels like you’re trying to move a boulder? That dreaded “Power Steering Assist Fault” message on your Ford Escape’s dashboard isn’t just annoying—it’s a serious safety concern that’s affected thousands of owners. The good news? Most causes are fixable, and you’ve got options beyond the dealership’s eye-watering repair quotes.
What Causes Power Steering Assist Faults in Ford Escapes?
The Ford Escape uses an Electronic Power Assisted Steering (EPAS) system instead of traditional hydraulic steering. When this system fails, you’re left with manual steering that requires significant effort—especially at low speeds.
Most Common Causes
- Torque sensor failure: The most frequent culprit, especially in 2008-2012 models
- Power Steering Control Module (PSCM) issues: Often integrated into the steering rack
- Electrical problems: Including blown fuses and battery issues
- Wiring faults: Damaged connections between components
The 2008-2012 Ford Escape and Mercury Mariner vehicles show the highest failure rates, with 2009-2011 models being particularly problematic. Even newer models through 2016 can experience these issues, with the 2008 Escape Hybrid having notable torque sensor problems.
Recognizing the Warning Signs
Your Ford Escape will typically show several symptoms before complete power steering failure occurs:
Telltale Symptoms
- Dashboard warning messages: “Power Steering Assist Fault” or “Steering Assist Fault”
- Intermittent steering assistance: Working fine one moment, heavy the next
- Steering wheel vibration: A “phantom shake” particularly noticeable at stops
- Extremely heavy steering: Especially at low speeds or when parking
- Complete loss of power assist: Requiring 10-20 times more effort to turn the wheel
Diagnostic Trouble Codes to Watch For
When you connect a diagnostic scanner, these codes often point to power steering problems:
| Code | Description | Typical Repair |
|---|---|---|
| B2278 | Steering Shaft Torque Sensor Fault | Torque sensor replacement |
| B1342 | Torque Sensor Circuit Malfunction | Steering column replacement |
| B2277 | Power Steering Motor Malfunction | EPAS motor/rack replacement |
| C2792 | Power Steering Motor Circuit Short | Wiring repair or EPAS replacement |
The frustrating part? Many EPAS failures happen without setting any diagnostic codes, making diagnosis trickier for both owners and mechanics.
Quick Fixes to Try First
Before heading to the shop, try these potential quick fixes that have worked for many owners:
Check Your Fuses
Two critical fuses protect your power steering system:
- F40 (5A): Located in the passenger compartment fuse box
- 80A fuse: Found in the engine compartment battery junction box
Many owners have solved their steering problems by simply replacing these fuses. Even if they look intact, clean the contacts—corrosion can cause intermittent connections.
Verify Battery and Electrical Health
The EPAS system is extremely sensitive to electrical supply quality:
- Test your battery: Weak batteries commonly cause EPAS malfunctions
- Clean battery terminals: Ensure tight, corrosion-free connections
- Check charging system: Confirm your alternator provides stable voltage
Official Recalls and TSBs You Should Know About
Ford has issued several recalls and Technical Service Bulletins (TSBs) related to power steering issues:
Safety Recall 14S05 (2008-2011 Escape/Mariner)
This recall covers certain 2008-2011 Escape and Mariner vehicles built at the Kansas City Assembly Plant through September 11, 2010. It specifically addresses torque sensor failures causing steering assist loss. Depending on diagnostic codes present, repairs range from PSCM reprogramming to complete steering column replacement.
Technical Service Bulletin 14-0016
This TSB addresses B2278 codes in 2008-2012 Escape and Mariner vehicles, providing a torque sensor service kit as a more economical solution compared to replacing the entire steering column.
DIY Diagnostic Steps
If you’re mechanically inclined, here’s how to diagnose power steering problems yourself:
Step 1: Basic Electrical Checks
- Check both power steering fuses mentioned earlier
- Test battery voltage (should be 12.6V when off, 13.8-14.2V when running)
- Inspect all visible wiring for damage, especially near the steering column
Step 2: Scan for Trouble Codes
Using a quality OBD-II scanner that can access body and chassis modules:
- Connect to the PSCM (Power Steering Control Module)
- Retrieve any stored codes
- Check if the scanner can communicate with the PSCM—no communication often indicates module failure
Step 3: Test During Different Conditions
Some EPAS failures only occur under specific conditions:
- Test when the engine is cold vs. hot
- Try gentle “wiggle testing” of electrical connectors
- Pay attention to intermittent symptoms—note when they occur
Repair Options and Costs
Depending on your diagnosis, here are the typical repair paths and their costs:
Torque Sensor Replacement ($300-$500)
The most common repair for B2278 codes involves replacing the torque sensor:
- Parts cost: $150-$200
- Labor: Approximately 1.6 hours
