OBD-II scanners are excellent tools that help mechanics understand what’s happening inside your car.
These scanners connect to a particular port under your car’s dashboard. Once plugged in, they can read and clear error codes, show how well your vehicle is performing, and even help predict problems before they get serious.
Let’s see the options for top OBD2 scanners in 2024!

Our Testing Methodology
If you want to understand how your vehicle is performing or uncover any issues under the hood, the best approach is to use one of the top OBD-II scanners.
We aimed to utilize a widely recognized vehicle for this evaluation to assess compatibility effectively, so we enlisted a Honda Civic (2005 model) and got to work. The reliable old car had just surpassed 250,000 miles, so we were apprehensive to discover what the diagnostic tools would reveal.
How We Assessed OBD-II Scanners
Recognizing that different OBD2 scanners suit various scenarios, we refrained from directly comparing them.
Instead, we determined which scanner excelled in each context and evaluated them based on that criterion. We meticulously documented each scanner’s features and began our assessment.
To trigger a check engine light, we disconnected the mass air flow sensor on the Civic, started the vehicle, and confirmed that the light illuminated.
Next, we connected each scanner and analyzed the following aspects:
- Time from connection to code display
- Number of live data Parameter IDs (PIDs)
- Number of freeze-frame PIDs
- Number of Inspection and Maintenance (I/M) Monitors shown
- Quality of the user interface (UI) via an app or the scanner itself
- Accessible tests, emissions check capabilities, and supplementary diagnostic resources
- Cord length (if applicable)
- Additional general observations
By comparing this assessment, we identified which OBD-II scanner excels for various applications and which needs to meet expectations.
Here are our top recommendations for the best OBD-II scanners.

How to Choose the Best OBD2 Scanner For You?
Vehicle technology is constantly changing and improving, so your OBD2 scanner needs regular software updates, too.
Here are some points you should consider when choosing an OBD-II scanner:
Know Your Needs
Are you a car owner who just wants to check for simple issues? Or are you a mechanic looking for powerful tools to help you fix cars?
An essential code reader or DIY scanner is perfect if you use it for personal reasons. These devices let you read codes and check live data quickly.
But if you’re a professional mechanic or run an auto repair shop, you should consider getting a professional-grade scanner. These advanced scanners offer features like detailed diagnostics and bi-directional controls, making them compatible with many different vehicles.
Balancing Price and Features
It’s easy to get the excellent, most expensive OBD2 scanner, but you should balance the cost and what you need.
- Primary code readers are the most affordable choice and work great for simple diagnostics.
- Investing in a more expensive scanner makes sense for those who work professionally because it provides essential capabilities.
Think about the features that matter most for your needs, and then choose a scanner that fits your budget!
Do Your Research and Read Customer Reviews
Customer reviews are super helpful when picking the suitable OBD2 scanner. They show you what’s great about each scanner and what might not work well.
When you read reviews, focus on these critical points:
- This will allow you to see how the scanner works in real-life situations.
- Check if reviews mention how well the scanner works with different car makes and models.
- It’s also important to know how easy it is to use and if it’s worth the money.
By learning from others’ experiences, you can make a smart choice and find the OBD2 scanner that’s just right for you!
Oh and…OBD2 Codes Are Automatically Deciphered in Torque360!
When you inspect the car, the OBD2 scanner provides you error codes indicating what’s causing the vehicle’s issue.
Consider this example:
A customer comes to you with his vehicle and wants an estimate of the repair cost. You inspect the car with a diagnostic tool and find a code (P0300). But wait! You get the error code, but how can you give the estimate for the repair part cost?
Simply, you’ll put this code into auto repair estimate software to create an accurate quote based on the diagnosis. This streamlines your process and ensures clarity and accuracy in your estimates.
