Search your OBDII engine code and you get back a description and reason why the code set, sensor specs as well as suggestion for clearing the condition.

Designed by top technicians and College automotive instructors, this app contains all of the Diagnostic Trouble Codes (DTCs) with description.

Each DTC will bring up the DTC SAE name, information on its cause and suggestions for its repair. These suggestions are general and are no way specific to the exact repair. It is up to the technician to use his/her experience and knowledge to determine the cause of the DTC.

All car makes and models are represented, some with specific detail.

No internet connection required, all data is stored inside the app!

This app explains codes better than any other. Not only does it give you the common definition but by vehicle as well.
The best by far.
