If your check engine light suddenly turns on, this compact OBD2 scanner can help you quickly find out why without immediately paying a mechanic for a diagnostic scan. It plugs directly into your car’s OBD II port and reads engine fault codes for most 1996+ vehicles that support OBD II and CAN protocols.
For a low-cost tool, it covers the basics well: reading and clearing engine codes, checking live data, and helping you confirm whether a repair fixed the issue.
