It fixed the car...
Worked like a charm. Computer gave an error code "Knock sensor error" and we replaced it with this, and the code cleared.

2012 Hyundai accent
Installed on a 2012 Hyundai accent that was throwing a knock sensor code. Not super easy to get to on the car but was easy to install once we got there. Solved the problem!

Not sure
The most I can say about this products is that is matchs the original part 100%, my husband cha ged the part yet the check engine light never went off. Took to have tested and same thing was indicated. They cleared the code, so far it has not came back on.
