Electric Power Steering (EPS) systems have become the standard in modern vehicles, offering improved fuel efficiency and a more responsive driving experience. However, like any complex system, EPS can malfunction. Knowing how to diagnose and potentially repair EPS issues can save you time and money. This guide provides a comprehensive overview of How To Repair Eps Of Car, covering common problems, diagnostic techniques, and potential solutions.
One of the first things you should do when experiencing EPS problems is to check your power steering fluid level. A low fluid level can indicate a leak and should be addressed promptly. Sometimes, simply topping off the fluid can resolve the issue. If you’re uncomfortable working with car fluids, consider contacting a qualified mechanic. It’s always better to be safe than sorry, especially when dealing with complex systems like EPS. After refilling the power steering fluid, you should test the steering to see if the problem is resolved.

Understanding Your Car’s EPS System
The EPS system utilizes an electric motor to assist the driver in steering. This motor is controlled by a computer that receives input from various sensors, including the steering wheel position sensor and the vehicle speed sensor. Understanding the interconnectedness of these components is crucial for effective EPS repair.
Common EPS Problems and Symptoms
Several issues can arise with the EPS system, each with its own set of symptoms. These include:
- Power Steering Warning Light: This is the most obvious sign of an EPS problem.
- Stiff Steering: The steering wheel becomes difficult to turn, especially at low speeds.
- Loss of Power Steering Assist: The steering wheel may suddenly become very light or heavy.
- Whining Noise: A whining noise coming from the steering column could indicate a problem with the EPS motor.
- Erratic Steering: The steering wheel may jerk or pull in one direction.
Diagnosing EPS Issues
Diagnosing EPS problems often requires specialized tools, such as a code reader to retrieve diagnostic trouble codes (DTCs) from the EPS control module. These codes provide valuable clues about the nature of the problem.
Using a Code Reader
A code reader can be plugged into the vehicle’s OBD-II port to access DTCs. Once the codes are retrieved, they can be looked up in a service manual or online to determine the specific problem.
Checking the EPS Motor
The EPS motor itself can be tested using a multimeter to check for proper voltage and resistance. This can help determine if the motor is functioning correctly.
EPS Diagnostic Process using a Code Reader
Sometimes, seemingly unrelated issues can impact your car’s performance. For example, a damaged battery can cause various electrical problems, including issues with the EPS system. Learning how to repair your car battery can be a valuable skill. Check out this helpful resource: how to repair car battery with epsom salts.
Repairing EPS Problems
Depending on the specific problem, repairing the EPS system may involve replacing faulty components, such as the EPS motor, steering wheel position sensor, or the control module.
Replacing the EPS Motor
Replacing the EPS motor is a complex procedure that often requires specialized tools and knowledge. It’s generally recommended to have this done by a qualified mechanic.
Replacing the Steering Wheel Position Sensor
The steering wheel position sensor can also be replaced, but it requires careful calibration to ensure proper operation of the EPS system. You may find useful information about car repairs in general in this article: how long to repair accident car.
