The GPED OBD2 Scanner is a handheld code reader for engine and emissions faults on most cars with a standard 16-pin OBD2 port: US models from 1996, EU from 2000, and Asian vehicles of the same era. Its selling point is a large library of 35,901 fault code definitions, so many codes come with a plain-language explanation instead of a number to look up. It also graphs and logs live sensor data and has F1/F2 shortcut keys for reading codes and checking I/M readiness. It is a basic engine-code tool: it does not read ABS, SRS, TPMS or SAS, and has no reset or programming functions, so shoppers who need those should look at a mid-range or professional scanner.

Rated 4.5 out of 5 from 43 ratings. Owners treat it as an easy, quick check-engine tool for the money; the common caveat is that it only covers engine and emissions systems.
This is a basic OBD2 code reader that plugs into a vehicle's standard 16-pin OBD2 port. It works with most US cars made after 1996, EU models made after 2000, and Asian vehicles from the same period. The menu supports 10 languages.
It has a library of 35,901 fault code definitions. It also graphs and logs live sensor data, so you can watch trends in suspicious readings. F1 retrieves trouble codes and F2 opens I/M readiness information. Left and right navigation buttons are included along with up and down.
To connect, plug the scanner into the OBDII port, turn on the ignition, and press OK. Start the engine to view live data. A transparent protector film is pre-applied to the screen and can be peeled off if it gets scratched.
