Updated September 07, 2018 by Gabrielle Taylor

We spent 25 hours on research, videography, and editing, to review the top selections for this wiki. When your car's check engine light comes on, it could signal anything from a trivial problem, like a loose gas cap, to more serious issues that require immediate attention. With one of these wireless OBD2 scanners, you can quickly find out what's wrong and save yourself an unnecessary trip to the mechanic. We've included both Wi-Fi and Bluetooth models that work with iOS, Android, and Windows. When users buy our independently chosen editorial picks, we may earn commissions to support our work.
