4.4/ 5

Engine light was on, 2011 Hyundai Elantra. Turned the key to on, diagnostics kicked in, and whalaa, O2 sensor was bad. Purchased item, used youtube for how to, reset the code and done, no more check engine light. $45 total cost, labor included. I was a little worried that I would have to read a War and Peace book to understand this. Very user friendly. If I can figure it out, I promise you will.

At the most basic level, the check engine light indicates that some sensor, somewhere in your engine, exhaust, or transmission, has provided unexpected data to computer.
