Hey People,

Unless you actually know how to use a code reader, you are simply wasting your money. The code reader retrieves the code from the vehicles on board computer, unless you know what the code means this device is useless to the average person. Furthermore, a check engine light can come on for many reasons and give a false code, you will have to know how to troubleshoot the problem. Is it a hard code? Some may ask, what does that even mean? As BL.Phoenix says you can go to Autozone and have them scan it for you for Free. After the scan, would you know where to begin or which component is at fault? Or is it a bad component or something else causing the check engine light to trigger.
