How do you fix electric power steering problems?
Electric power steering (EPS) systems have become a standard feature in modern vehicles, offering improved fuel efficiency and precise handling. However, like any other car component, they can encounter issues over time. In this article, we’ll explore common electric power steering problems and provide a step-by-step guide to diagnosing and fixing them.
Understanding Electric Power Steering Systems
Unlike traditional hydraulic power steering systems, EPS relies on an electric motor to assist with steering. This system eliminates the need for a power steering pump and fluid, making it more efficient and environmentally friendly. However, the reliance on electronics means that issues can arise due to electrical faults, sensor malfunctions, or software glitches.
Common Symptoms of Electric Power Steering Problems
Before diving into repairs, it’s essential to recognize the signs of a failing EPS system. Here are some common symptoms:
- Difficulty turning the steering wheel, especially at low speeds.
- Warning lights on the dashboard, such as the power steering or EPS indicator.
- Intermittent loss of power steering assistance.
- Unusual noises when turning the wheel.
- Steering that feels heavier than usual or inconsistent.
Steps to Fix Electric Power Steering Problems
Fixing EPS issues requires a systematic approach. Follow these steps to diagnose and resolve the problem:
- Step 1: Check the Battery and Charging System
Since EPS systems rely on electrical power, a weak or failing battery can cause issues. Use a multimeter to test the battery voltage and ensure the alternator is charging correctly. Replace the battery or alternator if necessary.
- Step 2: Inspect the EPS Fuse and Wiring
Locate the EPS fuse in the fuse box and check if it’s blown. Replace it with a fuse of the same rating if needed. Additionally, inspect the wiring and connectors for damage, corrosion, or loose connections.
- Step 3: Scan for Diagnostic Trouble Codes (DTCs)
Use an OBD-II scanner to retrieve any error codes related to the EPS system. These codes can provide valuable insights into the root cause of the problem, such as a faulty torque sensor or motor.
- Step 4: Reset the EPS System
Sometimes, a simple reset can resolve minor glitches. Disconnect the battery for about 10 minutes, then reconnect it. This action can reset the EPS control module and clear temporary faults.
- Step 5: Replace Faulty Components
If the issue persists, you may need to replace specific components, such as the EPS motor, torque sensor, or control module. Consult your vehicle’s service manual for guidance or seek professional assistance if you’re unsure.
When to Seek Professional Help
While some EPS issues can be resolved at home, others may require advanced diagnostic tools and expertise. If you’re unable to identify or fix the problem, it’s best to visit a trusted auto repair shop.

Frequently Asked Questions
What causes electric steering to go out?
Neglecting regular maintenance contributes to power steering failure. Without routine checks and servicing, issues like fluid degradation, hose deterioration, and pump wear can go unnoticed until they cause system failure.
How do you fix an electric power steering warning?
Below are the key steps to help you fix power steering warning light:
- Step 1: Check the Power Steering Fluid Level (Hydraulic Systems)
- Step 2: Inspect for Leaks.
- Step 3: Check the Power Steering Belt (Hydraulic Systems)
- Step 4: Test the Electrical Connections (Electric Power Steering Systems)
- Step 5: Reset the System.
How do you reset the electric power steering system?
If something doesn't line up when the computer collects this information, it will turn on the warning light. Often, you can fix the problem by pulling off the road, shutting the car off, and letting it sit for a minute. When you turn the car back on, the system will reset itself.
How much does it cost to fix an electric power steering?
On average, replacing your power steering pump can cost between $500 and $900, but it's essential to avoid more serious damage to the power steering system.
How do you fix a stiff electric power steering?
If electric steering is stiff only in one direction the usual cause is that the steering system is out of calibration and the usually fix is recalibrating it with the scan tool. Yes, this one really is that simple.
Can you still drive if electric power steering goes out?
If the weight of the steering wheel is still manageable, you may be able to drive the car to the nearest mechanic. Make sure to drive slow and stay on the outside lanes to minimize steering inputs.
Does electronic power steering need fluid?
Electric power steering (EPS) systems, unlike their hydraulic counterparts, don't require any fluid to function. These systems also have fewer moving parts and, instead of pulling power from the engine, EPS draws power from an electric motor.
Can electronic power steering be repaired?
Problems with the electric power steering can make the car dangerous, necessitating prompt repairs. Faults in the system can range from simple to complex, with some requiring the replacement of the steering rack. However, experienced professionals can often successfully repair EPS.
Will disconnecting battery reset electric power steering?
Disconnecting the battery cable for a short period will not fully reset your ECU because residual power remains in the circuits.
What to do if electric power steering goes out?
If the weight of the steering wheel is still manageable, you may be able to drive the car to the nearest mechanic. Make sure to drive slow and stay on the outside lanes to minimize steering inputs.
