Best OBD2 Scanner: Buyer’s Guide

Best OBD2 Scanner: Buyer’s Guide

You can save money on repairs or upkeep by keeping one of the best OBD2 scanners in your car. You do not want your check engine light to come on just as you’re about to go on a routine inspection out in the sticks.

Also, you can connect an OBD (on-board diagnostic) scanner directly to your car’s access port, which is right by the driver’s seat, to see what’s going on in your car’s computer. A simple light if you can fix or a problem that requires a professional will cost many thousands of dollars to resolve.

A car’s OBD2 scanner, sometimes called an OBD2 scanner in the United States, or an EOBD scanner in Europe, can also monitor a car’s engine, transmission, and other critical systems. Your mechanic normally has access to that kind of information.

You should always have this information on hand when taking your car in for routine maintenance or for a major repair. This will prevent you from being scammed into paying for unnecessary repairs.

What to look for when choosing an OBD2 scanner? – Buyer’s Guide

If you want to find out what’s wrong with your car or how it’s working, there’s no better way than to plug in a good OBD2 scanner and read the results. 

When you drive (or are towed) into your local car dealer or repair shop, this is the way they figure out what’s wrong with your car. Doesn’t that information belong to you as well?

Things to be kept in mind

  • Easy setup: The scanner will be useless if it takes forever to set up.
  • Faults and explanations: With the best OBD-II scanners, you’ll not only learn which faults your car has, but also learn how to fix it yourself or consult a mechanic.
  • I/M Readiness check: If you’re planning to pass your state’s inspection, a good scanner will run the major engine and emissions tests.
  • Accuracy: When the results of a scanner are inaccurate, it is as bad as having no information at all.
  • Size and weight: The scanner may end up staying in your toolbox rather than in your car to help you while on the road, if it is heavy and bulky.
  • Live data: The right scanner can help pinpoint an intermittent problem by analyzing the engine speed, timing, and other factors.
  • Graphs: A visual representation of it is much better, especially when you compare before and after data.
  • Warranty: Why shouldn’t your OBD-II scanner last at least eight or ten years like your car does? That said, the best bikes come with lifetime warranties.

OBD scanners are rated based on a wide range of criteria. It is important to consider whether you want a device that is wirelessly connected to your phone or tablet, or a handheld device that has its own display and cable. 

Consider longevity and choose a scanner that includes a lifetime warranty or software updates to keep up with changing automotive technologies. 

How about the size of the screen on a handheld scanner? You want a display that is easy to read, bright and has an icon-based interface for quick changes. Those who are clumsy should consider rugged scanners with rubber bumpers that absorb the shock if dropped.

Look for extras that some models include, like a multimeter, the ability to read a manufacturer’s proprietary codes, and the ability to export documents as Acrobat PDF files. 

These sophisticated devices are priced on par with scanners that can be purchased for under $100. A mechanic could do it in about an hour, making it a win-win purchase.


Thus, we hope you are able to now make up your mind regarding the OBD2 Scanner that suits your requirements the most. When you’re looking for an OBD2 scanner, keep these factors in mind and you’ll be sure to find the perfect one for your needs.
