Hi all, my 2005 LLY blew up so I found a good deal on a low mile 2006 LLY. I know the 2006 LLY is basically a de-tuned LBZ so I put my LLY injectors in it and removed a tooth from the crank tone wheel so it is not throwing a crank position code. I am getting code P0340 Camshaft position (CMP) Sensor Circuit and code p0341 Camshaft Position sensor performance. I cant find anything that tells me if the camshaft reluctor wheel is the same on the LLY and the LBZ. Or do I need to pull the timing cover and change it out.
2005 LLY to 2006 LLY

Did you accidentally swap cam/crank sensors or hook them up backwards?
Did you remove correct tooth on wheel? https://www.duramaxdiesels.com/forum/threads/lly-vs-lbz-reluctor-wheel.738/

I used the tread you just sent me to find out what tooth to remove. And so far the crank sensor fault has not come back up. I pulled the cam and crank sensors off of my 2005 LLY and put them on my 2006 LLY but the cam sensors got mixed up in the process. Thought I got the right one but I’m going to try the other one today and see if it changes anything. If that didn’t work my thought is to get a new one and try that. The way the wiring harness is set up I don’t think I could plug them in backwards, and if I did I would guess I would be getting crank and cam faults.
So I found out that i put the wrong sensor in the cam and switched it out for the right one and that code went away. Then the crank code came back up so I removed the sensor and i didnt get the nub all the way ground off so i ground it off smooth and then the crank code went away. For a few times I was cranking there was a p0374 high resolution system performance code then after a few cranks and resets of the codes I got p0016 crankshaft position - camshaft position correlatioin and p0336 crankshaft position sensor performance. Not sure where to go from here.
Bringing this up from tbe dead. Im currently looking at putting a lbz in my lly. So I would like to know how it ended up.

What are you looking to know? This swap has been around for over a decade.
So from my understanding. Grind 1 tooth off the crank tone ring. Use the lly sensors. Lly injectors with larger oring.
What about intake runners, y-bridge, front accessory bracket for the ficm to mount on, water pump. Everything else im thinking should go back lly for the truck rite?
Like fuel rails and fuel supply/return setup.
I have 100% lly injectors, 10mm cp3 and 475 over stock twin kit laying there.

Yes
Gotta swap all bracketry and intake runners etc over including the water pump as the inlets are not interchangeable.
Should be a fun setup!
