My check engine light comes on and off so I took it to auto zone and they told me it was my knock sensor.

But the young fella didnt know anything about it. Like where it goes. What it does to my kia. Nothing. PLEASE HELP. And I would like to know is it easy to change? And how much would a shop charge me to do it?

First of all, they are parts salesman, not techs.

A code never identifies a bad part, just a failed system.
You need a shop with a scan tool, not a code reader, to monitor the knck sensor to verify if it is working properly and the wiring needs to be checked as well.

Stop with the fuses. You need a shop with a scan tool that can monitor the sensor activities. Without a scan tool you are spending a lot of money on items that dont fix the car.
