Bests & Worsts Reviews from Amazon

Worked on my '04 Tundra to read and reset a code. The local mechanic shop wanted to swap out both of my catalytic converters due to an error code being thrown by the driver side rear exhaust gas sensor. I used this reader to check the code myself, a quick Internet search showed that sometimes the code is misinterpreted as a bad cat when it's really a bad exhaust gas sensor. I swapped the sensor myself with a $90 replacement and reset the code with this device, problem solved.
