Review on MUCAR CDL20 OBD2 Scanner - Check Engine Code Reader And Diagnostic Scan Tool For All OBD II Protocol Cars Since 1996, With O2 Sensor, EVAP System, And Smog Test Functions by Ryan Richards

For the price, this was a great deal. It's also incredibly easy to use. 3 stars because it didn't find the second code.I went to AutoZone to have my check engine light code read and the guy told me my Toyota was reading as a Audi. He gave me a code to google and it just didn't seem right. I figured he was doing something wrong and it would be nice to have one of these on hand for this issue and future issues as my car is getting older.When I tested with this, it pulled up a code that made much more sense, although it said the reader didn't have information on the code it was easy enough to google it. I went to a different AutoZone (this one was much better!) to try to get a confirmed reading of the code, just to make sure this thing worked. AutoZone did pull up the same code as this reader! However, there was a secondary code that AutoZone received that this OBD2 did not.Overall, I do still plan to keep this as it read the main issue and I won't use it in replace of a professional code reader.
