Maintaining your car to ensure your investment lasts for years doesn’t always come cheap. For most car owners, a trip to the dealership or local mechanic is at the top of the list when the dreaded check engine light illuminates. But sometimes you might be able to fix the issue yourself—the hard part is determining exactly what’s wrong.

That’s where OBD2 scanners come in handy. These devices plug into your OBD2 port and will let you know the error code, so you can troubleshoot the issue yourself. Before you purchase an OBD2 scanner, you’ll have to make sure your vehicle is OBD2 compliant. In Canada, all vehicles model year 1998 and on were required to be equipped with OBD2, but if you’re unsure, check your vehicle’s manual to confirm.

Using an OBD2 scanner is fairly straightforward. You simply plug it into your vehicle’s OBD2 port to diagnose what the issues are. Some scanners will also let you access driving data and stats, allowing you to actually fine tune and control certain settings for your vehicle.

Below, you’ll find our top picks for the best OBD2 scanners along with information on how to choose the one best for you and your vehicle.

Check Your Car’s Compatibility

Do You Need Bluetooth?

Some OBD2 scanners feature Bluetooth, which allows you to connect your smartphone and use a compatible app with the scanner. For some scanners, this is required in order to show you all the information. Keep that in mind when you’re shopping for OBD2 scanners and if you’re purchasing a Bluetooth one, that you have a compatible device to use with it.

Features To Look For?

The most basic OBD2 scanners will read and clear check engine lights, but more expensive ones offer advanced features such as data logging and monitoring other systems of your vehicle. Choose what’s best for your needs, based on the issues you’re experiencing with your vehicle.
