What to Look For in a Car Code Reader

Ease of Use

If you’re just getting into cars and haven’t had a car code reader before, it’s probably a good idea to purchase one that is simple to use. These scanners can have pretty advanced functionality, so it’s important to find one that isn’t too confusing and will help you figure out what’s wrong with your vehicle without too many steps.

Price

Car code readers can come in at many different price points. It’s important to keep in mind the features you need to get the best value for your money. If you know you’re going to be using the reader a lot, though, it may be worth it to spend a little extra to get the bells and whistles of the fancier devices.

Codes and Sensor Readings

What kind of codes—manufacturer, generic, etc.—and vehicle sensor readings do you need your reader to be able to interpret? Make sure you choose a model that’s compatible with your particular car.
