How to Clear Engine Light with FIXD
If your car’s check engine light just came on, don’t panic—you don’t always need to rush to the mechanic. Thanks to tools like the FIXD OBD2 scanner, you can read, understand, and even clear that pesky warning light from the comfort of your driveway. In this guide, you’ll learn exactly how to clear your engine light with FIXD, step by step. Whether you’re a first-time car owner or a DIY enthusiast, this process is simple, fast, and empowering.
By the end of this guide, you’ll know how to connect FIXD to your car, interpret trouble codes, fix common issues, and safely reset the engine light—all without breaking a sweat. Let’s get started.
What Is FIXD and How Does It Work?
FIXD is a smart OBD2 (On-Board Diagnostics) scanner that plugs into your car’s diagnostic port and pairs with a free mobile app via Bluetooth. Once connected, it reads trouble codes stored in your vehicle’s computer and translates them into plain English. Instead of seeing cryptic codes like “P0420,” you’ll get a clear explanation like “Catalytic converter efficiency below threshold.”
The real magic happens when you’ve fixed the issue—FIXD lets you clear the engine light with just a tap on your phone. It’s like having a mechanic in your pocket, but without the hefty bill.
Step 1: Check Your Vehicle Compatibility
Before you buy or use FIXD, make sure your car is compatible. FIXD works with most gasoline-powered vehicles made in 1996 or later in the U.S., and 2001 or later in Europe. Diesel, hybrid, and electric vehicles may have limited support, so check the FIXD website for specifics.
To confirm compatibility:
Look for the OBD2 Port
The OBD2 port is usually located under the dashboard, near the steering wheel. It’s a 16-pin connector, often black or gray. If you can’t find it, check your owner’s manual or search online for your car’s make and model.

Ensure Bluetooth is Enabled on Your Phone
FIXD connects to your smartphone using Bluetooth, so make sure it’s turned on. The app works with both iOS and Android devices, but you’ll need at least iOS 12 or Android 6.0 to run it smoothly.
Step 2: Install the FIXD Sensor
Once you’ve confirmed compatibility, it’s time to install the sensor.
Locate the OBD2 Port
Get into your driver’s seat and look under the dashboard, near the steering column. The OBD2 port is usually within arm’s reach. It might be covered by a small panel—gently remove it if needed.
Plug in the FIXD Sensor
Take the FIXD sensor out of the box and plug it firmly into the OBD2 port. It only fits one way, so don’t force it. Once connected, the sensor’s light should blink green, indicating it’s receiving power.
Keep the Sensor Plugged In
Unlike some scanners you remove after use, FIXD is designed to stay in your car. It continuously monitors your vehicle and sends alerts to your phone if something goes wrong. Just make sure it doesn’t get knocked loose.
Step 3: Download and Set Up the FIXD App
Now that the sensor is in place, it’s time to set up the app.
Download the App
Go to the App Store (iOS) or Google Play Store (Android) and search for “FIXD Automotive.” Download and install the free app.
Create an Account
Open the app and sign up using your email or Google account. You’ll need to verify your email to activate your account.
Pair the Sensor with Your Phone
Turn on your car’s ignition (you don’t need to start the engine). Open the FIXD app and follow the on-screen instructions to pair the sensor via Bluetooth. The app will search for the device—select “FIXD” when it appears.
Add Your Vehicle
The app will ask for your car’s make, model, year, and engine type. Enter the details accurately so FIXD can provide the most relevant diagnostics.
Step 4: Read the Trouble Codes
With the sensor connected and the app set up, you’re ready to read the codes.
Open the FIXD App
Launch the app and tap “Scan Now.” The sensor will communicate with your car’s computer and retrieve any stored trouble codes.
Review the Results
The app will display a list of active and pending codes. Each code includes a plain-English description, severity level (low, medium, high), and estimated repair cost. For example, a “P0171” code might show as “System too lean (Bank 1)” with a note that it could be a faulty oxygen sensor or vacuum leak.
Understand What the Codes Mean
Don’t ignore the descriptions. A “high severity” code might mean you need to stop driving immediately, while a “low severity” issue could be something simple like a loose gas cap. Use the app’s built-in repair guides or search online for more details.
Step 5: Fix the Underlying Problem
Here’s the most important rule: Never clear the engine light without fixing the problem first. Clearing the light won’t repair your car—it just hides the warning. If the issue persists, the light will come back on.
Common Fixes for Check Engine Lights
- Loose or faulty gas cap: Tighten it or replace it if cracked. This is one of the most common causes.
- Oxygen sensor failure: These sensors monitor exhaust gases and can wear out over time. Replacement costs $100–$300.
- Spark plug or ignition coil issues: Misfires can trigger the light. Replacing spark plugs is usually inexpensive.
- Catalytic converter problems: Often caused by neglecting other repairs. Can be costly to replace.
- Mass airflow sensor dirt: Clean it with a specialized spray or replace it if damaged.
DIY vs. Professional Help
Some fixes, like tightening a gas cap or replacing spark plugs, are easy to do yourself. Others, like catalytic converter replacement, may require a mechanic. Use the FIXD app’s repair difficulty rating and your own comfort level to decide.
Step 6: Clear the Engine Light with FIXD
Once the problem is fixed, it’s time to clear the light.
Ensure the Repair Is Complete
Double-check that the issue is resolved. For example, if you replaced a sensor, make sure it’s installed correctly and the wiring is secure.
Turn On the Ignition
Turn the key to the “on” position (but don’t start the engine). This powers the car’s computer without running the motor.
Open the FIXD App and Scan
Launch the app and tap “Scan Now.” Wait for the scan to complete. If the repair was successful, the app may show “No Active Codes” or list only pending codes.
Clear the Codes
Tap the “Clear Codes” button in the app. Confirm the action when prompted. The sensor will send a command to your car’s computer to erase the stored trouble codes.
Verify the Light Is Off
Turn off the ignition, wait 10 seconds, then start the engine. The check engine light should be off. If it comes back on, the problem may not be fully resolved, or a new issue has occurred.
Troubleshooting Common Issues
Even with the best tools, things don’t always go smoothly. Here’s how to handle common problems.
The App Won’t Connect to the Sensor
Make sure Bluetooth is on, the sensor is plugged in, and your phone is within 30 feet. Try restarting the app or your phone. If that doesn’t work, unplug the sensor for 10 seconds and reconnect it.
The Engine Light Comes Back On
This means the underlying issue wasn’t fixed. Re-scan with FIXD to see if new codes appear. Some problems, like intermittent sensor failures, may take time to reappear.
“No Communication” Error
This usually means the OBD2 port isn’t getting power. Check that the ignition is on. If the port is damaged or corroded, you may need professional help.
Sensor Light Is Off
If the green light on the sensor isn’t blinking, it’s not receiving power. Check the OBD2 port and try plugging the sensor into another vehicle to test it.
Tips for Using FIXD Effectively
To get the most out of your FIXD scanner, follow these best practices:
- Scan regularly: Even when the light is off, run a quick scan every few months to catch early warnings.
- Keep the app updated: FIXD releases updates to improve accuracy and add new features.
- Use the maintenance reminders: The app can track oil changes, tire rotations, and more based on your driving habits.
- Share reports with your mechanic: If you do need professional help, the app can generate a detailed report to save time and money.
Conclusion
Clearing your engine light with FIXD is a simple, empowering process that puts car care in your hands. By diagnosing issues early, fixing them promptly, and using the app to reset the system, you can avoid costly repairs and keep your car running smoothly. Remember: the light is there to help you—don’t ignore it, but don’t fear it either. With FIXD, you’ve got the tools to stay informed and in control.
So next time that little orange light pops up, you’ll know exactly what to do. Plug in, scan, fix, and clear—your car (and your wallet) will thank you.
