Blowing SNSR-2 fuse when under boost and continuous spinning fan

Can anyone here help me I have had my car troubleshooted for my cooling fan coming on right at startup, weather the ambient temperature is hot or cold, and I have checked all the relays and fuses related to the cooling fan and they are all working perfectly.
I also have the wiring line and plug for the coolant temperature sensor and the sensor check and they also are reading as they should however the fan still spins at cold startup and throughout the time the car is on until you turn off the ignition before it shouts.
The car doesn’t overheat at all and the ac works fine and fan spins on high speed when the ac is on just can’t get it to turn off.

Finally the upstream o2 sensor fuse keeps blowing when the car goes into boost which is super annoying and when that fuse get blown out the fan keeps spinning even when the ignition is off until you replaces the fuse.
The car will take on any long distance and operation as it should but as soon as you go into boost the the SNSR-2 blows right out. Can anyone please give some insights.

How many miles on the car? Has the low speed fan always come on as soon as the key in the on position? Have you tried swapping the fan relays or tapping on the relay when it's on (may be stuck)?

The SNSR-2 fuse covers a lot. Everything but the FIs in this diagram.

The fan started coming on at startup I’ve 2 weeks ago, I have switched around the relays and all and and it changes nothing. Could it be the crankshaft sensor because I know it is routed through that fuse and I got a check code, P0335, and a P9448 codes, which both runs through that same fuse. And now the car is idling rough.

The car had 99k miles on it

P9448 appears to be bogus as there is nothing listed for that. The P0335 is crank sensor performance issues but I doubt it is the reason for your fan being on.

Perhaps it is a short in the wiring as that is what usually blows a fuse. I know if the Engine Coolant Temp sender goes wonky the ECU will usually turn on the fan.
