Don’t Ignore an EPS System Warning Light: What You Need to Know

AvatarByCarl Frisch

The EPS system warning light is a dashboard indicator light found on many modern cars. It is typically illuminated when there is a problem with the Electric Power Steering (EPS) system. The EPS system provides power assistance to the driver for ease of turning the wheels. When this light illuminates, it usually indicates a malfunction with the electric power steering or possibly other components of the EPS system. In most cases, it will need to be diagnosed and repaired by an experienced mechanic in order to restore proper steering function and turn off the indicator light.

What Is Electronic Power Steering (EPS)?

Electronic Power Steering, or EPS, is an advanced system used in cars and other vehicles to assist with steering. The system uses computer sensors and an electric motor to adjust the amount of power being applied to the steering wheel, allowing for more precise control over the vehicle. This reduces driver fatigue and helps make the driving experience more comfortable. It also helps provide better fuel economy by reducing the amount of physical effort needed to turn the wheel.

How Does the EPS System Work?

The EPS system works by using a series of sensors that detect how much torque is being applied to the steering wheel by the driver. The signals from these sensors are sent to a computer which then adjusts the amount of power being sent to a motor mounted on the steering column. This motor then adjusts the pressure applied to turn the wheels, providing additional assistance when needed while still giving drivers full control over their vehicle.

Common Causes of an EPS System Warning Light

An EPS System Warning Light can be triggered for a variety of reasons such as low battery voltage, faulty steering sensors or motors, malfunctioning relays or fuses and worn out power steering pumps. Low battery voltage can cause an EPS warning light due to insufficient current being supplied to keep all components running smoothly. Similarly, faulty motors and sensors can cause issues with how effectively power is transferred through the system, resulting in an illuminated warning light on your dashboard. Malfunctioning relays or fuses can also lead to issues as they are responsible for controlling how much power is sent from certain components in order to keep them running optimally. Lastly, worn out power steering pumps can cause problems due to reduced fluid pressure which may not be enough for proper operation of all parts within your car’s power steering system.

How To Diagnose And Troubleshoot An EPS System Warning Light

The first step in diagnosing and troubleshooting an EPS System Warning Light is checking battery voltage levels as this will indicate whether there is sufficient current being supplied for all components in your car’s power steering system to work properly. After checking voltage levels you should then inspect all fuses and relays for any damage that may have caused them to malfunction or become damaged over time. After this you should test the outputs of both your cars’ steering sensor and motor in order to ensure they are working correctly as well as verifying that your car’s power steering pump is in good condition by having it serviced regularly or replacing it if necessary.

Common Repairs For An EPS System Warning Light

Common repairs for an EPS System Warning Light include replacing a low battery or charger unit if it has been determined that this is causing insufficient current being supplied throughout your car’s power steering system; replacing any faulty electronic components such as those found within both your sensor and motor; replacing any damaged fuses and relays; and lastly replacing any worn out power steering pumps that may be contributing towards reduced fluid pressure throughout your car’s system causing it not operate properly.

How To Prevent An EPS System Warning Light

There are several steps you can take in order to prevent an EPS System Warning Light from appearing on your dashboard such as regularly checking battery voltage levels; inspecting all wiring connections for any loose connections which could lead to potential faults; inspecting belts and hoses regularly for signs of wear or tear which could be causing extra strain on parts within your car’s power steering system; performing regular maintenance on your car’s power steering pump; and avoiding extreme driving conditions whenever possible which could lead potential issues with other parts within this complex mechanism located beneath your hood.
