Real easy to use and a bargain at $10 for the sensor.
Instead of running to the mechanic each time, you can plug it in and see the codes yourself with your smart phone.
And for those who will comment go to advanced auto, auto zone or alike. Why waste time when you can scan yourself.
I have like 3 of these. And they work like a charm. You can also get the year premium for $50 to get live agents and answers for basic trouble shooting and guides on to what part needs repair.
