Understanding Your Honda Accord’s Electric Power Steering (EPS) System
Before we tackle the issues, let’s briefly understand what makes your Honda Accord’s steering tick. Unlike older hydraulic systems, Electric Power Steering (EPS) uses an electric motor to assist your steering, offering several benefits.
This modern setup is more fuel-efficient and allows for more precise control, but it also introduces a different set of potential complications compared to its fluid-based predecessors.
The Shift from Hydraulic to Electric
For decades, power steering relied on a hydraulic pump, hoses, and fluid. This system was robust but constantly drew power from the engine, even when no assistance was needed.
Honda, like many manufacturers, transitioned to EPS to improve fuel economy and reduce emissions. This also simplified the system by removing messy fluids and a belt-driven pump.
How EPS Works: A Quick Overview
Your Accord’s EPS system is a sophisticated electronic network. It consists of a steering angle sensor, a torque sensor, an electric motor, and an Electronic Control Unit (ECU).
When you turn the wheel, the sensors detect your input. The ECU then calculates the necessary assist and directs the electric motor to apply force to the steering rack, making turning effortless.
Common Problems with Honda Accord Electric Power Steering
Identifying the symptoms is the first step in diagnosing honda accord electric power steering problems. Here are some of the most frequent complaints we hear from Honda Accord owners.
Understanding these signs can help you pinpoint the issue and decide on the best course of action. This section covers common problems with honda accord electric power steering problems and their typical manifestations.
Steering Wheel Feels Stiff or Heavy
This is perhaps the most common symptom. If your steering wheel suddenly feels like it’s fighting you, requiring significant effort to turn, your EPS system is likely failing to provide assistance.
It might feel heavy all the time, or intermittently. This can be particularly noticeable at low speeds or when parking.
Intermittent Power Steering Loss
Imagine driving along, and suddenly, your power steering cuts out, then comes back a few seconds later. This intermittent loss can be jarring and dangerous.
It often points to electrical issues, such as a faulty sensor, a loose connection, or a problem with the EPS control module itself.
Warning Lights on Your Dash (EPS Light, Check Engine Light)
Modern vehicles are great at telling you when something’s wrong. If your EPS warning light (often a steering wheel icon with an exclamation mark) illuminates, it’s a direct signal of an EPS system fault.
Sometimes, a general Check Engine Light (CEL) can also appear, especially if the EPS system is communicating errors to the main engine computer.
Unusual Noises from the Steering System
While EPS systems are generally quieter than hydraulic ones, unusual noises can indicate a problem. You might hear a whining, grinding, or clicking sound when turning the steering wheel.
These noises could stem from a failing electric motor, worn bearings in the steering column, or issues within the steering rack itself.
Steering Pulls to One Side
If your Accord consistently pulls to the left or right, even on a flat road, it could be an EPS issue, though it’s often related to alignment or tire problems.
However, if the pull is accompanied by other EPS symptoms or feels like inconsistent assist, the steering system might be contributing to the problem.
Diagnosing Honda Accord Electric Power Steering Problems: Your DIY Guide
Now that you know the symptoms, let’s get into how to honda accord electric power steering problems by diagnosing them. This section is your practical guide to troubleshooting.
Remember, safety first! Always perform these checks on a level surface with the parking brake engaged.
Visual Inspection: What to Look For
Start with a simple visual check under the hood and around the steering components. Look for any obvious signs of trouble.
- Wiring and Connectors: Check for any frayed wires, loose connections, or corrosion around the EPS control unit, motor, and sensors. A common issue can be a partially disconnected or corroded connector.
- Steering Column: Look for any obstructions or signs of damage around the steering column that might impede its movement.
- Tires and Alignment: While not directly EPS, uneven tire wear or obvious alignment issues can mimic or exacerbate steering problems.
Checking Your Battery and Charging System
The EPS system is entirely electric, making a healthy 12V battery and charging system absolutely crucial. Many EPS issues, especially intermittent ones, can be traced back to insufficient voltage.
- Test Battery Voltage: With the engine off, use a multimeter to check your battery’s voltage. It should read around 12.6 volts.
- Check Charging System: With the engine running, the voltage across the battery terminals should be between 13.5 and 14.5 volts, indicating the alternator is charging correctly.
- Inspect Battery Terminals: Ensure battery terminals are clean, tight, and free of corrosion. A poor connection can lead to voltage drops, confusing the EPS ECU.
Scanning for Diagnostic Trouble Codes (DTCs)
This is where modern diagnostics shine. An OBD-II scanner is an essential tool for any DIY mechanic. It can read codes stored in your car’s computer, including those related to the EPS system.
- Connect Scanner: Plug your OBD-II scanner into the diagnostic port (usually under the dashboard on the driver’s side).
- Read Codes: Turn the ignition to the “ON” position (engine off) and read any stored or pending codes.
- Research Codes: Specific EPS codes (e.g., C-series codes) can point directly to a faulty sensor (like the steering angle sensor), the EPS motor, or the control module itself.
Steering Angle Sensor Calibration Issues
The steering angle sensor tells the EPS ECU the position of your steering wheel. If this sensor is out of calibration, the system won’t know how much assist to provide, or it might think the wheel is turned when it’s straight.
While often requiring a specialized scan tool for proper recalibration, knowing this is a potential issue can guide your diagnostics. Sometimes, a battery reset can temporarily resolve minor calibration glitches, but a professional calibration is usually needed for a lasting fix.
Practical Tips and Best Practices for Addressing Honda Accord Electric Power Steering Problems
Once you’ve diagnosed the potential issue, it’s time to consider solutions. This section provides honda accord electric power steering problems tips and best practices for repairs and replacements.
When You Can DIY vs. When to Call a Pro
Some EPS problems are within the scope of a confident DIYer, while others are best left to licensed professionals.

Component Replacement: Steering Rack, EPS Motor, or Sensor?
Depending on the diagnostic codes and symptoms, you might need to replace a specific component. The most common culprits are:
- EPS Motor: If the motor itself is failing, you might hear grinding noises or experience complete power steering loss. This component is often integrated into the steering rack.
- Steering Angle Sensor: If codes point to this sensor, replacement (and subsequent calibration) may be necessary.
- Steering Rack Assembly: Often, the EPS motor and control unit are part of the entire steering rack. If multiple components fail or if internal rack issues are present, replacing the whole assembly might be the most cost-effective and reliable solution. Always use OEM or high-quality aftermarket parts for safety and longevity.
Calibration After Replacement
A critical step after replacing any major EPS component, especially the steering rack or steering angle sensor, is calibration. The new component needs to “learn” its correct operating parameters relative to your vehicle.
This usually requires a specialized scan tool (like Honda HDS) that can perform the necessary calibration procedure. Skipping this step can lead to continued issues, incorrect steering feel, or even error codes.
Preventative Maintenance and Care Guide for Your EPS System
While EPS systems are generally low maintenance, a proactive approach can significantly extend their lifespan and help you avoid future honda accord electric power steering problems. This section offers a sustainable honda accord electric power steering problems care guide.
Regular Battery Health Checks
As mentioned, your 12V battery is the lifeblood of your EPS. Regularly check its health, especially if your Accord is getting older or if you live in extreme climates.
A weak battery can cause intermittent EPS issues, making it seem like a more complex problem than it is. Consider replacing batteries every 3-5 years as a general rule.
Tire Pressure and Alignment
While not directly part of the EPS system, proper tire pressure and wheel alignment significantly impact steering feel and can mask or exacerbate EPS issues.
Ensure your tires are inflated to manufacturer specifications and have your alignment checked annually, or whenever you notice uneven tire wear or a pull in the steering.
Keeping Electrical Connections Clean
Corrosion on electrical connectors is a silent killer for many automotive systems, including EPS. Periodically inspect and clean the main EPS connectors (usually near the steering rack or EPS control module) using electrical contact cleaner.
A small amount of dielectric grease can help prevent future corrosion and ensure good conductivity. This is a simple, eco-friendly honda accord electric power steering problems tip that can prevent costly repairs.
