Here’s How You Can Read and Reset the Check Engine Light in under 60 Seconds – and Save $150+

Clearing the check engine light comes in handy when troubleshooting issues and testing for glitches in your car’s onboard computer. While most repair shops will charge $150 to do this for you, there’s a simple way to read and clear the check engine light yourself – even if you’re a beginner when it comes to cars.

  • No paying $150+ at the repair shop.
  • No driving to the nearest auto parts store. 
  • No disconnecting your car battery. 

Here’s how:

Step 1: Plug This Device into Your Car

The first step to diagnosing and clearing your check engine light is to plug FIXD into your OBD2 port. Every gas-powered vehicle made since 1996 comes equipped with this port that’s usually located on the driver’s side under the dash.

This little port lets you “talk” to your car’s onboard computer and understand what’s wrong when the check engine light comes on. All you need is a device to translate your “car talk” into simple terms. That’s FIXD.

Step 2: Connect Your iPhone or Android Smartphone

Once it’s plugged into your car, FIXD connects to any iPhone or Android smartphone via Bluetooth to scan your car and translate the check engine light into plain English.

There are thousands of reasons why your check engine light could be triggered. FIXD eliminates the guesswork by telling you what your check engine light means in plain, easy-to-understand terms and how much it’ll cost to fix.

Step 3: Hit “Clear Engine Light” and Drive Happy

FIXD makes it super easy to clear the check engine light. This is especially useful when you have an issue that’s easy to fix at home, such as a loose gas cap or simple DIY repair.

After scanning your car, simply hit the “Clear Engine Light” button in the app to clear the check engine codes stored in your car’s computer.

At this point, the check engine light should be off, and you have successfully reset your check engine light. While this doesn’t necessarily mean your problem is fixed, it can be very helpful when you’re doing simple repairs at home or checking for computer glitches.

If the light doesn’t come back on, you’re good to go! If it does, you can call the FIXD Mechanic Hotline to help diagnose and repair the concern that is causing the code.

    1. My FixD app. After I plugged in the sensor is telling me that
      1. P0700- Transmission control module. I have NO transmission problems so what else should I check.
      2. P1794- Automatic transmission BARO signal. I only get that this problem may cause vehicle to not pass inspection…what else?
