I have a LC -1 and had a lot of similar problems when it was new. It was error after error. It would try and warm up then fault out. I updated the software to the newest version off thier website which was supposed to increase the speed of the warm up cycle and some other things. I flashed that to the cable and it has worked great since then. Hope that helps, it's all I got for you.
Maybe contaminates on the sensor itself?
MIne LC-1 is brand new and its getting alot of errors and im gonna clean the sensor tip..
