P0016 — Crankshaft Position - Camshaft Position Correlation Bank 1 Sensor A

Hey fellow techs, I am looking for a known good cam and crank waveform for the listed vehicle. This is what I have captured. P0016 is stored, info states code will set if one tooth off or more. Code is not current. Camshaft variance on bank one hovers around 1.5-2 degrees. Bank 2 hovers around zero. I'm not sure if that's enough to code. I'd like to compare waveforms. Thanks

Here is as close to the 2014 3.5 that I have. diag​.​net/msg/m4thda4i2d…

Thank you for that. My cam sensors are both square waves. That's interesting, it looks like that has one square wave and one analog signal?

Must not be the same for that engine.

I realize I did not answer your question. I don't use cam and crank signals much, only transducer.

Make sure to check your phasers, that they are not sticking. I have a mustang in here with a 3.7l and I found the phaser sticking causing a p0017

I have seen a number of these and have taken pictures of the stretched chain. To test the phasers simply actuate them one at a time and they should advance the same number of degrees. If it does you have a bad chain. We don't replace the secondary chains, only the main chain and the water pump. Also tensioners.

Thank you, with the code being not current, it was cleared and the vehicle was picked up for now. I will test that when it returns. This engine had been replaced with a used late last year. The replacement may be worn as well. We shall see.

Hello, I have a few different waveforms from a known good 2014 flex with a 3.5. Chased a miss with identifix, who helped very little! What pattern are you looking for? I have crank to cam and exhaust on Bank One, crank to intake and exhaust Bank Two and all cam signals at once. Aall on pico

Thank you but this particular engine only has 2 cam sensors and the VCT controls the intake cams only. I don't believe they are the same. This is a turbo 3.5l.

The scan tool does the work for you. Monitor VCT ERR pids, this is the difference between commanded and actual timing. I think it takes at least 6° to trigger the DTC. If you cant reproduce the issue its not a stretched chain (cant be intermittently stretched). Suspect the phaser hanging up, the solenoid mechanically not working or oil feed passage issues. What kind of oil filter is on the…
