hi. so what is the temp at which the fan turns on? Does it go by coolant temp? is it 215F? On idle my I was at 206F after driving but oil at 192F and ATF at 176F. Im using an OBD reader.

i know when the AC turns on so does the fan. Does someone have the protocol to check it? No OBD codes were made. Its has 120K so if I could change a sensor to help that would be great but I'm not sure which one.

Many obdii code readers allow you to see various temperatures at sensors. My ELM327 does. They only cost about $10, and software for phone app is free.

The BCM turns the fans on and off with imput from various sensors.
Coolant temp, ambient air, A/C compressor, vehicle speed, engine RPM, humidity, etc etc.
