It’s the new Coolant temperature gauge sensor not the temp 2 sensor causing
the high reading is what I was trying to say in my broken English haha.
Gowesty sells this kit to correct the issue too.

Saw it yesterday when I was researching my response. It uses the thermos
switch to calibrate the temp apparently.
