Can I drive my car with power steering assist fault Ford?
In most Ford vehicles with electric power-assisted steering (EPAS), you can still drive, but you should not rely on the steering assist. Expect heavier steering, especially at low speeds, and plan to reach a service facility as soon as safely possible. If the steering becomes completely unresponsive, stop and arrange a tow to a dealer or qualified mechanic.
What the fault means for EPAS systems
Power steering assist in Ford vehicles typically relies on an electronic control module and sensors to provide steering help. A fault can be triggered by issues such as a faulty EPAS control module, a bad steering angle sensor, damaged wiring or connectors, a blown fuse, or low battery voltage. When the system detects a problem, it may reduce or remove assist, or display warnings like “Power Steering Assist Fault” or “Service Power Steering.” In some cases, the vehicle may enter a fail-safe or limp state to preserve steering control.
Safety considerations when the fault occurs
Driving with a power steering fault requires extra caution. The steering will feel heavier and require more effort, particularly at slower speeds or when maneuvering in tight spaces. Avoid high-speed driving, aggressive turning, or emergency maneuvers until the system is inspected. Maintain a wide, predictable lane position and allow extra time for braking and turning. If at any point the wheel becomes difficult to turn or responds erratically, safely pull over and arrange assistance.
To help you respond right now, consider these steps:
- Reduce speed and look for a safe area away from traffic where you can stop if needed.
- Activate hazard lights to warn other drivers.
- If the steering remains partially usable, proceed slowly toward a service location with extreme caution; do not engage in aggressive or high-speed driving.
- Do not ignore the warning—consider towing if the steering becomes overly heavy or unresponsive.
- Check basic conditions such as battery health; a weak 12V battery can contribute to EPS faults.
These steps help you navigate safely to a repair facility and minimize risk while the issue is diagnosed.
What a Ford technician will check during diagnosis
When you bring the vehicle in, technicians typically inspect the EPAS system and related components to determine the cause of the fault. They may review diagnostic trouble codes (DTCs), inspect electrical connections, and verify sensor data to pinpoint the failure.
- EPAS control module and wiring harness integrity around the steering column.
- Steering angle sensor or wheel position sensor accuracy and calibration.
- 12V battery voltage and charging system health; low voltage can trigger EPS faults.
- Fuses, relays, and any signs of corrosion or damaged connectors.
- Software versions and any applicable service bulletins or recalls for the model.
After diagnosis, the repair plan will depend on the root cause. Common fixes can include module or sensor replacement, wiring repairs, fuse replacement, or software updates/calibrations. If a recall or warranty covers the issue, Ford or the dealer may perform the repair at no charge.
Summary
A power steering assist fault in a Ford typically means you can still drive, but with reduced or absent steering assistance. The safest approach is to slow down, drive carefully to a safe location, and have the system diagnosed and repaired by a qualified technician. Do not ignore the warning, and seek service promptly to restore normal steering feel and safety. Always check for recalls or service bulletins that may apply to your specific model and VIN.
