Speedometer Not Working, And Check Engine Light.
2002 Kia optima.
So yeah we had the engine replaced by kia because of a few bad lifters, a week or so later the speedometer stopped working and the check engine light came on. My dad told me to go out and check for any loose wires or something... So i found where the speed sensor is and followed it to a big bunch of taped up cables... and that leads into the "drivers cabin?". so that really didn't help me being 15 and all, we'll probably take it to kia, but hoping for some direction here?
