Can a 2003 6.0 run w/o SYNC?

I searched (quite a lot!), so please excuse me if this is a dupe. We just got finished changing the HPOP on our 2003 PSD. During the initial troubleshooting, I read one of m-chan68's informative posts listing the things required for a 6.0 to run. Going through them, two conclusions were found: 1, the ICP was low, seemed correct, and other clues pointed to a bad HPOP; and 2, was there was no CMP/CKP SYNC, and no FICM SYNC. Since the primary problem appeared to be ICP related, we followed that path, and indeed found a bad HPOP. After changing that, the truck starts, but while looking at the scan tool data, (EASE Diagnostics PC based scan tool) I noticed that both SYNC signals are always NO. I measured the resistance of the CKP and CMP sensors at the PCM terminals, and both were within specs. No codes are being set, and the truck seems to run OK, although maybe a bit underpowered.

Can the engine run without SYNC?
