I have these codes coming up and the service dept couldn't tell me what they meant when I was there...I am taking it in in a few days but I seriously thought they could tell me what they meant. In the meantime I am sticking close to home and not going far.
P0016 is the crankshaft position (CKP) to intake camshaft position
correlation; P0017 is the exhaust camshaft position correlation.
P0016 sets when 'The ECM detects 8 of the last
10 cam sensor pulses occur during the incorrect crankshaft position."
P0017 sets when 'The ECM detects 25 out of the last 35 cam
revolutions occur with 2 cam sensor pulses outside the CKP window."
Basically, you're getting pulses when they
shouldn't happen, from both cam sensors, or the CKP is generating incorrect
window info. Since the CKP is the common element, it's probably the culprit.
The cam position sensors are at the back of
the head, one on each side corner. The CKP is under the oil filter housing,
above the starter. To replace the CKP, you're supposed to remove the intake
manifold and starter.

If you bought this at a car dealer, you should take it back for them to fix it (hope you at least got a 30 day warranty). If you bought it privately, it's your problem now.
The P0606 code is relayed to the PCM (Powertrain Control Module), that's the computer. The fault is saying there is an internal memory problem with it. This may or may not be causing all the other fault codes, but it should be the first one to be fixed.
The P0014 & P0016 are related to the camshaft actuator solenoid and crankshaft position sensor.
P0125 is for coolant temperature being too low, P0128 is for coolant temperature not rising fast enough at start up, these could be a bad thermostat.
P0172 is for a rich fuel mixture detected.

Scott,
I as well have a 2002 chev blazer 4x4 4.3L, and though I have not exerrienced your paticular problem, I have experienced Service Engine Light on, and generaly I have found it is one of your sensors.
You could have a bad sensor causing your rev problem. What I do is determine if the vehicle still runs as if the service engine light has not come on.
If it runs the same, in my experience it is not as crucial as if you have a performance issue, as you do with reving. If I was you I would try to get to your mech ASAP.
I am not aa mech but, I know our chev blazer very well, and how it should perform.
Hope this helps,
Chuck

I think your sensors are pattern parts and the readings /resistances are not the same as the original parts ,try some bosch units is my first suggestion ,
