Rebuilt motor P0016/P0017

Hey dudes and gals, time to pick your brains. So my coupe is running finally but I keep getting a CEL P0017 and P0016. Crankshaft and Camshaft correlation. Motor was rebuilt.

Crank sensor is new.
Cam phasers were replaced about 2 months ago during rebuild.
Cam actuators were replaced about 2 months ago during rebuild.
Chain tensioner is new.
Balance shafts are deleted.
ZZP LNF ECM

CEL doesn't come back on but the codes are immediately pending, but will come on again if the car is turned off then back on.

Really at no idea what could be causing it other than the cam timing being off which doesn't make sense as it's been double checked and set twice.

Need to get emissions done on the car by the 29th and I know it won't pass with a CEL on.

Already re-timed it once and it's doing the same thing. I will be at work soon so any replies will be delayed.

Any ideas? Thanks

A local to me had a similar issue and there was a problem with the head gasket (he never completely explained what it was exactly)

Oh? Head gasket is new of course with ARP studs. You thinking it is something like an oil gallery is blocked partially?

I think it was an issue with a partly blocked oil gallery

At least you have APR studs so a replacement is cheaper

Also even with the codes cleared and engine off, the cam phaser angle reads nothing on my RPD.

He pulled the actuator out and noticed different amounts of oil getting to each actuator (he only had the code for 1)

I pulled them yesterday and it didn't look like they were getting a lot of oil. Might see about pulling them again later and checking in the hole that feeds them. They might even be plugged up inside. Thanks!

Granted when I clear the codes, it will run fine on initial start-up for a few seconds and then it chugs to where to where it sounds like it is cammed. HOWEVER it does clear up and will idle normal after that, codes will be pending. Next start-up the light will come on after a few seconds and stay on, does the same thing every time. I do think you are right and they might not be getting the right amount of oil to function properly.

You even figure out this issue? My car is currently throwing p0016 and p0017 but will run, start, idle, and even boost just fine.

I'm in the exact same boat you are my dude. Any luck in solving the issue?

Does anyone have a solution for this? I too have the same codes on a new+rebuilt engine (crate engine I rebuilt). The engine runs fine as far as I can tell and I've confirmed timing. I don't know why it would matter, but like the original post I have no balance shafts. Both of my cam actuator solenoids seem to be getting similar amounts of oil.

DTCs P0016/P0017 set when the calculation of crank position by CKP sensor and CMP sensor (Bank 1 intake/exhaust) disagree by > 9.9 degrees of crank angle. These DTCs indicate implausible camshaft/crankshaft sensor correlation by comparing the differences between calculated camshaft and crankshaft. These are known as conditional DTCs.

Since the DTCs only set with the engine running, this indicates a mechanical fault as opposed to an electrical one. With both intake and exhaust cams being flagged for a timing correlation issue with the crankshaft, I’d suspect you are off one tooth on your camshaft to crankshaft timing. These DTCs will also cause the VCT to be disabled. If you’re suspecting that the issue is being caused by low oil pressure to the VCT phasers, unplug both VCT solenoids before starting the engine. That will leave the phasers on their locking pins so that they don’t affect timing.

My bet is your out one tooth on crankshaft you need to re time motor

If it is off by one tooth cant the ECU adjust the timing accordingly? I know its not ideal but if the car is running fine is it the end of the world?

No ECU can adjust for a base timing fault. A slightly stretched chain is one thing; being off an entire tooth is another.
