I had codes:
p0335 = CKP Sensor A circuit performance
p1372 = CKP sensor A-B correlation

The starter comes out (2 long bolts) and that could take awhile because its a tight fit to unwire and get out. Disconnect wiring from starter also. The sensor is fairly easy to get out with 1 bolt holding it in. Make sure you disconnect the battery also. I put the front of my car on ramps. The sensor is almost a foot below the exhaust manifold in the middle of the engine block. I thought it would be directly under the exhaust manifold, but it's not.

Took about 2 hours, but I'm old and slow. If you have everything in position it may only take 1 hour or less.

The CKP sensor is about $105 from the dealer but GMpartsdirect.com has it for about $55. I didn't do the CKP System Variation Learn Procedure because I don't have a ($2500-3500) Tech2 GM scan tool. (The Equus and other scanners won't do this operation I think.) I tells you to do the CKP learn procedure, but my car runs just like before without doing it (other people have said this also). If my car was running funky I would have had to have it towed to a GM dealer for them to do it.

Everything runs good. No stalls under 1/4 temp and at low RPM (I kept it in 2nd gear with the revs over 1K-1.2K until it got over 1/4 temp mark. My sensor was bad for a year with it stalling at an intersection in Winter while warming up. You just put it in Neutral or park to restart it. Then 3 weeks later it did it again. Kind of scary at first. Then I read and webbed about it and figured it only stuttered at around 1/4 temp or less. That's when it switches to sensor A from B at this certain heat range. The sensor only got worse over time. The drop in revs is from 300-500rpm and enough to stall the engine when the sensor is bad.
