I am over 50% sure the pre VVT will run with the CAM sensor disconnect
It might be a easy next test

Technical Do I need to get my ECU reprogrammed/repaired?
Euro 4 with a robotised gearbox has a different engine number no idea what’s different
169AXB11 02
I had a 1.2 05 dynamic with flyby wire throttle and and 1.1 06 active with cable
Most 1.1 Active were cable as were 03/04 1.2 dynamic
But I have no idea how this transfers into anything at the moment
Ok 
Back to basics:
Did the engine you removed still run?
Is your current set-up showing..then clearing.. the Immobiliser symbol ?
I had a 2004 for 14 years.. so have some experience
Only time it immobilised was when I rushed the Start.. didnt let the self-test complete

Just had a physical look at all 3 types
Seem to use same sensors (crank and cam) in 04 square, 55 plate square and 06 plate round.
Still looking for other differences.
06 plate round has conventional throttle cable, but 55 plate is a Dualogic with fly-by-wire.
Otherwise, no obvious differences so far.
Still looking...
The U1600 is a normal random error that often crops up and is normally just a glitch and normally nothing to worry aboutOk

The original poster has a P0335
This error is detected if the variation in position of the crankshaft is not within the acceptable range of values or cannot be learnt (with signal not valid detail) or if the control module recognizes the camshaft impulses but not the crankshaft impulses (with general electrical fault detail). As a result, the engine is switched off.
After trying to fit an engine that’s not identical to the original
Agreed..as covered last week
My question was pointed towards
'why no spark'
Mistiming would still spark
No rotation signal : No Spark ( is rev counter working...??)
Old engine question..
Ensuring we dont have the
'spark generator overload failure'
Like in the FIRE Puntos.. was a common failure

Is it not the code itself that stops the engine ?Agreed..as covered last week

The last part of the discrimination of the code
“ As a result, the engine is switched off.”
Of cause I could be wrong

Or is that the problem. When you look up the P0335 definition it says: Crankshaft position sensor - Circuit Malfunction. nothing about camshaft position? Would it not need to have a problem with the cam sensor if that was a consideration. Mind you, I now find myself wondering if a faulty cam sensor - or it's circuit - might stop the sparks because the poor wee ECU wouldn't know when to fire the plugs if the cam sensor was not giving it the signal it needs? If you google it (yes I know, sigh) there are a lot of guesses which come up but I'd still want to start with basically verifying the circuit continuity on the crank and maybe cam, sensor.
Different cam pulleys
One keyed one not
Have to look harder when I get back home

Don’t believe the internet
The description I post is direct from fiats troubleshooting guide
Of cause if the crank is wrong it will also put the cam out

Continuity on the circuits is fine.
So changing the new cam pulley for the old one might fix it?
Means I'd have to redo the timing belt again but not the end of the world
Those pictures are revealing. The one on the left, with the Torx bolt holding on it's cam pulley is of the floating (unkeyed) flavour with no timing mark. The one on the right has a keyed pullet. You can see the timing mark on the older engine quite clearly whereas the newer engine has a tippex mark on it, probably because someone has changed the timing belt at some time without loosening the cam pulley bolt. I now find myself wondering if this engine has been timed up wrongly? Did you hear it running before it came out of the car?
nope, not interchangeable.
Not yet
Try clearing the code and disconnect the cam sensor
Leave it disconnected what code do you get now

Not a clue. Got the engine as-is.
Will try with the old cam sensor and cam sensor disconnected.
PS you can also clearly see where the dowel is on the pulley with the hex bolt.
which then leads me to think, Is there a substantial difference between the pulleys? which isn't nice to thing about because I really don't think they'll swap over
The good thing is that not being a VVT engine I don't think it's interference so unlikely the valves and pistons will have got together if the timing is out
