P0118-000 Siganl too high

Replaced engine and car has been sitting awhile. I got it all back together and have this code. I have changed out the sensor, no change. Temp gauge does not move. Have cleared the code and it comes back. I'm sure this wan't an issue before it sat. Nothing looks like mice have done any damage. So anybody had to deal with this? Maybe a wiring diagram so I can trace it back or check continuity? I think I am too deep into this and need to step back and come back from a different direction and hope to get someone to point LOL. It's therapy for me but sometimes it isn't LOL Thanks guys
