What is EPS Light in Hyundai?
EPS stands for Electronic Power Steering, which is a system that helps you steer your Hyundai by using an electric motor instead of a hydraulic system.
The EPS light is a warning light on your dashboard that indicates that there’s an issue with the power steering system in your vehicle.
The EPS system uses an electric motor to assist with steering, which is controlled by a computer module. The module receives signals from various sensors, such as the steering angle sensor, vehicle speed sensor, and torque sensor, to determine the appropriate amount of power assistance required for steering.
The EPS system also utilizes a power steering control module (PSCM) to communicate with the vehicle’s main computer.
When you start your Hyundai, the EPS light should come on briefly as part of the system’s self-check. If the light stays on or comes on while driving, it means there’s a problem with the EPS system that requires attention. It’s important to note that the EPS system does not affect the brake or acceleration functions of your vehicle.
Causes of EPS Light in Hyundai
1. Faulty Power Steering Motor or Sensor
The EPS system relies on an electric motor to assist with steering. If the motor fails or experiences a malfunction, it can cause the EPS light to turn on. Additionally, there may be issues with the sensors that communicate with the motor, which can cause an EPS light problem.
2. Worn or Damaged Power Steering Belt
The power steering belt helps transfer power from the engine to the power steering pump, which is an essential component of the EPS system. Over time, the belt can wear out, become loose, or break, which can cause issues with the power steering and lead to an EPS light issue.
3. Low Power Steering Fluid Levels
Power steering fluid is essential for the proper functioning of the EPS system. If the fluid level is too low, it can cause the power steering pump to work improperly, resulting in an EPS light issue.
4. Electrical Connection Problems
The EPS system relies on several electrical connections to communicate with various sensors and modules. Loose, corroded, or damaged connections can cause issues with the system and make your EPS light come on.
5. Battery or charging system problems
This is quite rare but it happens. The EPS system relies on the vehicle’s electrical system to function properly. If the battery is weak, the alternator is failing, or there are other issues with the charging system, it can cause problems with the EPS system, leading to an EPS light issue.
Symptoms of an EPS Light issue in Hyundai
1. Difficulty Turning the Steering Wheel
If you’re experiencing difficulty turning the steering wheel, especially at lower speeds or when parking, it could be a sign of an EPS light issue. This symptom may be more pronounced in cold weather or after starting the vehicle.
2. The Steering Wheel Feels Stiff or Heavy
A malfunctioning EPS system can cause the steering wheel to feel stiff or heavy, requiring more effort to turn. This symptom can also be accompanied by a clicking or grinding noise when turning the wheel.
3. Strange Noises When Turning the Wheel
Unusual noises, such as whining or groaning, may occur when turning the wheel due to a problem with the EPS system. These noises may be more pronounced at lower speeds or when turning sharply.
4. EPS Light on the Dashboard
The most obvious sign of an EPS light issue is the EPS light illuminating the dashboard. This light typically appears as a yellow or red steering wheel icon.
5. Vibration or Shaking in the Steering Wheel
A malfunctioning EPS system can cause the steering wheel to vibrate or shake while driving. This symptom may be more noticeable at higher speeds or when driving on uneven roads.
Diagnosis of EPS Light in Hyundai
1. Check the Power Steering Fluid Level
The mechanic will check the power steering fluid level to ensure it’s at the correct level. If the fluid level is low, it could be a sign of a leak in the system or another issue.
2. Inspect the Power Steering Belt
When you are trying to diagnose the EPS light, it is important that you inspect the power steering belt for signs of wear or damage. A worn or damaged belt can cause the EPS light to come on, and if it needs to be replaced, this will solve the issue.
3. Check the Electrical Connections
Loose, corroded, or damaged electrical connections can cause issues with the EPS system. Ensure that you inspect the connections and repair or replace any damaged parts as needed.
4. Scan for Error Codes
The EPS system is equipped with sensors that can detect malfunctions and trigger error codes. Use a diagnostic tool to scan for these error codes, which can provide insight into the underlying problem.
5. Test the Power Steering Motor and Sensor
If all other potential causes have been ruled out, then you should test the power steering motor and sensor to ensure they are functioning correctly.
How to Fix EPS Light in Hyundai?
1. Refill Power Steering Fluid
If the power steering fluid level is low, you may simply need to refill the fluid to the correct level. This is a relatively straightforward and inexpensive fix, typically costing between $50 and $100.
2. Replace the Power Steering Belt
If the power steering belt is damaged or worn, it will need to be replaced. The cost of a new belt and labor to install it usually ranges between $150 and $250.
3. Repair Electrical Connections
If the issue is with the electrical connections, you can repair or replace any damaged wires or components. The cost of this repair can vary depending on the extent of the damage, but it typically ranges between $100 and $300.
4. NReplace Power Steering Motor or Sensor
If the power steering motor or sensor is malfunctioning, it may need to be replaced. The cost of a replacement motor or sensor, as well as the labor to install it, can range between $500 and $1000.
How to Prevent Future EPS Light Issues
To prevent future EPS light issues, it’s essential to maintain your Hyundai’s power steering system. Here are some maintenance tips:
- Check power steering fluid regularly: Check the power steering fluid level regularly and refill as needed.
- Replace power steering fluid: Change the power steering fluid at the recommended intervals specified in your vehicle’s owner’s manual.
- Inspect power steering belt: Have the power steering belt inspected regularly for signs of wear or damage, and replace it as needed.
- Avoid overloading: Avoid overloading your vehicle or using it to tow heavy loads, which can put excessive strain on the power steering system.
