The Ford Focus is a popular car model that has been in production since 2008. Like all automobiles, the Ford Focus relies on a network of fuses to protect its electrical systems. One critical system protected by fuses is the electronic power-assisted steering (EPAS). When a fuse related to the EPAS fails, it can cause the power steering to malfunction, making the car challenging to drive. In this article, we will explore the specific fuses associated with the electrical steering in the Ford Focus and provide insights into troubleshooting and resolving power steering issues caused by fuse problems.

What You'll Learn
Fuses required for power steering
The fuse for the EPS system in a vehicle is generally marked as "EPS" or "Power Steering". Its current capacity is typically large, ranging from 30A to 60A, depending on the vehicle's design and the EPS system's power requirements. The EPS system fuse is usually located in the vehicle's fuse box, which is typically found in the engine compartment or easily accessible areas like under the steering wheel, on the side of the dashboard, or in the panel beside the passenger seat.
For a Ford Focus, specifically the second-generation model produced in North America from 2008 to 2011, the fuse box is located below and to the left of the steering wheel, near the brake pedal. You can access it by removing the cover under the steering wheel.
When the electric power steering system fails or experiences a current overload, the fuse will blow to protect the motor, ECU, and other vital electronic components. This prevents further damage to the system. If the EPS fuse blows repeatedly, it is recommended to seek professional repair services to avoid more severe circuit issues that may impact the vehicle's safety and drivability.
Additionally, Advance Auto Parts offers replacement fuses for the Ford Focus, ensuring reliable functionality and protection for your vehicle's electrical systems.

Location of fuse panels
The location of the fuse panels in a Ford Focus depends on the model year of the car.
For the second-generation Ford Focus produced in North America between 2008 and 2011, the fuse panel is located below and to the left of the steering wheel by the brake pedal. To access it, you need to remove the cover under the steering wheel.
For the Ford Focus Electric based on the Focus Mark III, produced from 2012 to 2018, the fuse panel is located on the right side, below the glove box. The power distribution box, on the other hand, is located in the engine compartment, in the electric motor compartment, in front of the 12-volt battery box.
In addition, for Ford Focus ST models, the fuse block is located in front of the battery box.
It is important to refer to the appropriate fuse box diagram for your specific Ford Focus model and year to accurately locate the fuse panels and identify the functions of each fuse.

Cigar lighter fuse
The cigar lighter fuse for a Ford Focus depends on the model of the car. For a 2001 Ford Focus, the cigar lighter fuse is Fuse #46, a 15 AMP fuse. For a 2002 UK model ST170, the cigar lighter fuse is #47, also a 15 AMP fuse. For a 2008-2011 Ford Focus, the cigar lighter fuse is №3 (Power point) or №15 (Front power point) in the Engine Compartment fuse box. For a 2017 Ford Focus ST3, the cigar lighter fuse is Fuse 39, a 20 AMP fuse located under the glove box in the passenger footwell.
It is important to refer to the owner's manual for specific information on the location of the cigar lighter fuse for your specific model of Ford Focus. The manual will provide a chart or diagram that can help you locate the correct fuse.

Steering angle sensor
The Ford Focus steering angle sensor is a crucial component that improves the car's performance and safety. It is primarily used in the ESC system to maintain stability by feeding the steering-wheel angle data. This data is combined with inputs from yaw sensors and ABS wheel speed sensors, allowing the Ford Focus to apply individual brakes as needed to prevent loss of control, especially when navigating sharp corners during sporty drives. The sensor enables fine steering at low speeds and provides better road feedback at high speeds, catering to both normal road users and performance drivers.
The newer electric systems in Ford Focus vehicles have made it possible to calibrate the steering angle sensor for efficient and accurate power-steering assistance. This calibration enhances the driving experience and strengthens the Ford Focus's position as a globally preferred vehicle.
In some cases, recalibration of the steering angle sensor may be required after certain repairs or adjustments. For example, if the steering rack is replaced, the steering column must be properly aligned and reattached to the rack. Software tools like FoCCCus, FORScan, or Ford's VCM are necessary for recalibration, as they provide access to sensor values and the recalibration program.
The steering angle sensor is available for various Ford Focus models, including those with different engine and transmission configurations, such as the 2.0L Duratec HE engine and the 5-Speed Manual Transmission - MTX75. It is designed to fit most Ford Focus models, ensuring that owners can benefit from improved stability and performance.

Power steering failure messages
Power steering failure can be a serious issue, making your car difficult to control and compromising your safety. The power steering system in your car relies on a hydraulic pump or electric motor to assist you in turning the steering wheel. When this system fails, you will experience a significant increase in resistance when attempting to turn the wheel.
There are several warning signs that your power steering may be failing. One of the most common issues is a leak in the fluid lines, which can lead to a drop in fluid pressure. Over time, a worn seal or a small flaw in a hose can deteriorate, resulting in pump failure. Contaminated fluid, whether due to insufficient cleaning or external debris, can also cause pump damage and component failures. Additionally, power steering fluid has a limited lifespan and should be replaced when it becomes old and ineffective.
Other warning signs include unnatural sounds, such as screeching, squealing, or grinding when turning the steering wheel. These sounds may indicate low power steering fluid, a faulty power steering pump, or a worn serpentine belt. If you hear a quiet creaking sound, the upper bearings on your struts could be worn. Vibrations or shuddering in the steering wheel, especially at slow speeds, could indicate a power steering issue or failing components, such as a bad power steering pump or worn tie rods.
If you suspect a problem with your power steering, it is important to refer to your owner's manual and consult a qualified mechanic. In some cases, you may be able to address the issue yourself by replacing fuses or adding fluid, but always exercise caution when working on your vehicle's systems.
