2005 5.4 Replaced head gaskets, timing chains, cam phasers. Started it up and got code P0345 CMP sensor circuit malfunction (bank 2 driver side)and it would not idel. I unpluged it and it ran fine, the I pluged it back in and pulled the pass. side and it ran fine. It will run with one or the other pluged in but not both. Drove it for a few days and then got codes P0011 and P0021 (camshaft timing over-advanced both sides) and it droped down to about 10 miles gallon with lose of power. I pulled both CMP and brought it to TDC on the number 1 cylinder. Looking in the hole were the CMP goes (bank 1 pass. side) the tooth on the trigger wheel is at 5 clock just getting ready to pass by the CMP. With it at TDC on number 5 cylinder (bank 2) the tooth is at 7 clock it had passed the CMP. Any ideas

 

good chance you didn't allign it correctly

 

Tearing it back down now, I checked it twice but then again it broke down at my dads house and all the work was done out side with a high of 6 degrees.

 

just put the crank key way at the 12 oclock you can then move your cams around without hitting a piston

 

After you have the front cover off, there is a little timing mark at the bottom of the crank(with engine at TDC before removing the crank pulley and being able to see the L and R on the phazer on their respective side of the engine). You will need to put the 1 off colored link on the chain lined up with that timing mark. Then the 2 off colored(copperish) marks will go on either side of the arrows off the L or R on the phazer(L is left bank and R is right bank). This is how you time this engine.

 

you don't have to find the links- lay the chain down on a table stretch it out so that you have no space between the two halfs of chain at one end will be two links side by side mark them the other end will one link side ways mark it the single link goes at the crank

also some chain has 2 links at both ends just mark bothand put your timing mark between them

 

Got it apart and at TDC, the L on the left cam is between the 2 colored links and the I on the right cam is between the 2 colored links. This is how the book i have tells me to set them up, a Chiltons

 

The chain on the left side has more slack then the right, about half inch

 

How did you resolve this issue. I have the exact same problem. I replaced the cam phasers. I took the front cover off just to inspect everything. It all looked good. The links were all perfectly aligned. So I put it all back together I get the original problem which is rough idle unless one of the CMP's is unplugged. Sound familiar? I think the issue is the VCT sensors. Anyway, let me know how you resolved this.
