Have you looked in the Waveform Library ?

Sorry, no such engine in database.
On a dodge 5.7, similar waveforms, your timing is off.

On the 3,1,1 sequence, the good waveform has falling edge of the first 1 from 3,1,1 matches with 3.5 crankpulses, towards left of the gap.

Abouuut, 4.5 crankpulses more to the left the cam should be.

I'm a little late to the conversation but I'm battling a similar situation with a 2011 jeep grand Cherokee w/5.7L w/VVT. 62 miles after overhaul and have P0016, timing correlation DTC. New timing chain and crank gear, reused cam phaser, new CKP and CPS sensors. Engine starts and runs very well. Waveform very similar to SRT 8 but CKP has no gaps with 0 volts. Can timing be verified just by looking at the waveform or does some math get into it? Do I need to disconnect VVT solenoid harness prior to starting test? Tried to attach waveform?

Any help greatly appreciated
