7.3L white smoke, almost total loss of power, heavy vibration

Cruising down the highway and truck just lost almost all power and started vibrating pretty violently. Pulled over and let it idle, was idling a little rough and was blowing white smoke. Barely limped it to a local garage. Ran an injector buzz test and everything came back normal so it isn't the UVCH. Pulled the codes and got a p1280 and p0470. I know p1280 is ICP sensor could that be the only problem? truck can't even get out of its own way.

Unplug the ICP, setting the PCM to run a default value. If it idles better, then that's probably it.

Didn't let it get hot and melt a piston did you? That would be my thought. If it's vibrating really bad like a miss, but the injectors are ticking, you've got a compression problem somewhere.

I don't think so no, the EGTs were below 1000 when it happened
