2000 Silverado 5.3L, 4X4, 167K
I need to replace the Crankshaft Position Sensor. The manual states that
after replacement it must be connected to a scan tool for a "CKP System
Variation Learn Procedure". Is this something that needs to be done at a
dealership or can it be done with a generic scan tool? Is there a way to do
it without a scan tool?
Thanks for any advice,

Most generic scan tools won't:
You can go to a local shop, and maybe get that done for about $30.00 to
But, make sure they check to see that it's set no more than + or - 2%
The distributor drive gears have a tendency to wear in the middle on these
and the HEI type 3 distributors. The reason being that, the cam gear
castings are a bit rough.
If the sync is off, and the distributor gear is good, GM makes a shim kit,
to move out the CKPS. Due to the plastic timing cover warping.
RK, you're describing the camshaft position sensor adjustment AKA
cam synch, he's asking about crankshaft variation relearn.
They are two entirely and unrelated procedures not to mention
that the 5.3 doesn't have a distributor to begin with.
Yes it is. I probably should have mentioned it was a "New Style".
I got the new sensor in today but we weren't able to do the learn procedure.
It seems to run fine (only drove it about six miles home). Is it possible
that I won't have to do it? I am going to the dealer Monday for an unrelated
recall, should I ask them to do it even if it's still running fine?
