If your car’s check engine light comes on, you’re probably going to pay about $50 for a diagnostic if you take it to your neighborhood garage, or more if you go to the dealership — a lot of scratch for a problem that might be as cheap and easy to fix as a faulty temperature sensor. If you have a 1996 or newer vehicle that’s OBD II compliant then check out this standalone scanner.
With support for multiple trouble, pending, generic, and manufacturers’ codes, it’ll interpret that annoying check engine light and show you the results on an easy-to-read backlit LCD display. It’ll also reset and clear codes. Amazon’s selling the scanner for $37.
