Crank sensor 2012 Yukon Denali 6.2l

[RAFJR]

If I replace the crank sensor, will I have to do a re-learn or will it fire right up and perform fine?
If a re-learn is necessary, will the vehicle drive to a repair shop?
Or am I better off buying a tech II tool here: https://www.cnautotool.com/goods-1568-GM+Tech2+GM+Scanner+-CANdi++TIS.html

It will run just fine... It would be a good idea to do the relearn, but it should
start and run just fine
