Also it got warmed up the past couple times and huge surge of power lasting several seconds to a full minute wanted to jump through my garage on its own.
Any ideas?

To start with you are working on the wrong sensor for code 15.
Code 15 is for a problem on 2 wire sensor to pcm.
Not tempt gauge.
The dash gauge has a one wire sensor?
Does you dash have gauge or hot light or both?
Explain the power surge?
Like engine speeding up on it own or fast idle?
Why are you running it in gear when testing or sitting in garage?
