Further Findings - today, the code comes back.
Smarty is showing an interesting finding; the camshaft position sensor jumps about on acceleration upwards, not downwards.
I'm wondering what could be causing that.
I have also been told that I should replace the cam sensor too.

Findings are shown in the video if anyone can help.
The spikes in the camshaft rpm set the code.
It didn't ding this time because it was already set.

Just thinking out loud, but I believe the next step would be to put a scope on the cam sensor signal to compare it with a known good waveform and to see if it drops out at a higher RPM.Originally Posted by monkeh
I was just wondering if you have a bad cam signal or if the ECM is not processing the signal correctly.
It could also be a cam crank correlation error causing the issue.
Ideally, replacing cam and crank sensors with new OEM would be a good idea.
It may even be worthwhile to try switching the cam and crank sensors around to see if you can get a crank sensor error.

I wouldn't know where to get a suitable waveform from.
Maybe at idle?
The original crank sensor got shoved back in yesterday.
I am sending the Standard parts back for a refund, as they are potentially faulty.
I'm awaiting a contact back from a friend who services Cummins with OEM parts to see if he can help source parts.
I begrudge paying quadruple the amount for a Mopar unit; that is probably just a stamped Standard part.
In the meantime, I've another pair of Delphi's on their way to satisfy the cam, and the crank is renewed.
Delphi over here is a brand I can put a little confidence in.
I hope it's not the ECM; I have a repair shop to fall back on if everything fails. (3-hour drive).
I am determined to nail this on the head myself. I am bettering myself.

Yes, I think you are on the right track with the sensors.
I agree it’s best to try and figure these things out and gain more knowledge along the way.
I checked the Pico waveform library but nothing for your 2006 2500.
My thinking was if you had a known good, you could compare it with yours to see if the sensor signal looks correct and if it remains present at the sensor and then at the ECM when the fault occurs.

Did the Delphi sensors fix the issue?

I've not had a chance to fit them yet; the weather here in the UK hasn't been forgiving of late.
I received them Friday; hopefully, I will have a go tomorrow.

UPDATE:
Problem solved. (For now, knock on wood)
Pair of Delphi's went in.
Crank and engine RPM remained steady on the gauge, with no fluctuation.
Brief rip around the block, but no issues.
I intentionally left the fault code current and active.
It has now cleared by itself.
Medium cruise down the motorway at about 2000rpm, it remained constant.
Same with cruise at 1000rpm and at hellfire at 3000rpm (Tunnel run).
It seems that either the standard motor parts unit was faulty or replacing these sensors in matched pairs is a good idea.
On the plus side, I now have a Cummins UK parts account.
They wouldn't sell me new crank sensors, only reconditioned ones.
Thanks for the help and suggestions; they worked because I wouldn't have thought about the cam sensor.

Great news, thanks for the update.
