I looked into this for somebody a while ago. The cause almost every time was that the O2 wire was melted on the exhaust. I know you said nothing is burnt or cut but I thought I'd pass that along in case it deserves a closer look.

yea, i've looked all over and can't find anything and i've heard a bad ground will cause voltage spikes. i can't find the link to the wire diagram, and right now i am fighting with my son so i will look later.

Go get yourself a FSM... and start troubleshooting. You obviously have a short somewhere. it's very difficult to troubleshoot from thousands of miles away. Find out where that circuit feeds the +12VDC and go from there. You can measure the resistance of each circuit. When you read 0(ish) Ohms, Then you are on the right track.
