Default coolant sensor quit working

Team, Please help me out!

I just swapped out a faulty oil pressure sensor on my 2000 C5 bone stock LS1. In the process, I accidentally cut the engine coolant temp sensor wires on the driver side cylinder head. I performed a quality wire repair, with shrink wrap. The sensor works properly when the ignition key is in the "run" position, but the engine is off. When I start the engine, however, the engine temp gauge jumps up to 260*F, and the DIC says "ENGINE TEMP xxx*F"

Anyone have this issue before, or have any clues for me?

I cleared the DTC codes, and that seems to have fixed it. The gauge and DIC function as they should.

easy fix!
