Love this little gadget. Plug it into your OBD port and leave it there. It constantly monitors for pending and confirmed problem codes, provides reports, recommends the most frequent repairs. It also provides real time operating conditions, such as, vehicle speed, engine rpm, fuel level, coolant temperature, and other parameters. It also has a neat little feature called Smog Check that tell you if your car is ready for an emissions test.
