BAFX Products Bluetooth OBD2 Scan Tool for Check Engine Light and other Diagnostics - Android Compatible
Purchased this to use on my 12,000 truck. Code came up as being a bad O2 sensor. Thing is is that my truck has 4 o2 sensors! Well...... after using the detailed screen that shows the readings from all the electronic emissions parts I was able to isolate which O2 sensor was bad rather than pulling off each one and checking one at a time! What a great time saver!
