In removing the coil pack, I must have stressed the loom to the point where one of the wires came out of the pin in the cam position sensor plug.

As I have read in my research, these plugs/wires are very brittle. Of the three wires on this sensor (Green w/black stripe, pink, solid green), the solid green wire on mine has come loose - not visible by the naked eye either. In messing with the plug, I noticed the wire came out. I forced it back in, codes gone, car runs fine. I will be replacing this with a new plug/pigtail which I will crimp onto the existing wires. Toyota does not sell this part, so its going to have to be aftermarket. Dorman 645-744 looks to be the right part.

Hope this helps save someone a few hours of time and a possible wallet raping from the dealer.
