On my 2003 Tahoe, the check engine light shows on now a P0336 code, which is Crankshaft Position sensor failure.
Truck keeps on stalling everytime I use it for weeks now, and it's getting worse and worse
Before attempting changing it I saw that this CPS needs the PCM to relearn the new sensor. Does anyone has ever experienced this repair?
And can confirm that it is an obligation to do so about that relearn procedure? Because I am not equiped with a good OBDII device.

If I am not mistaken you just replace it and then go for a 15-20 minute drive and it will relearn.
