Technical Do I need to get my ECU reprogrammed/repaired?

Pretty sure fly by wire throttle was used on Euro3/4/5 dualogics,
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
 
I am over 50% sure the pre VVT will run with the CAM sensor disconnect

It might be a easy next test
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...
 
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
The U1600 is a normal random error that often crops up and is normally just a glitch and normally nothing to worry about

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 ?

The last part of the discrimination of the code

“ As a result, the engine is switched off.”

Of cause I could be wrong
 
Righty - I'm back out in the garage now and able to have a better look.

Pics attached of the timing setup on both engines.

Also found the old cam sensor, here's a pic of both. I believe the old one is on the left and the new one is what I've been trying to start the engine with (possibly the issue, could try it with the old sensor and see if that works?)

The OP here is getting an error code that’s says the cam is not where it expected to be
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.

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.
Different cam pulleys

One keyed one not

Have to look harder when I get back home
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?

Not a clue. Got the engine as-is.

Will try with the old cam sensor and cam sensor disconnected.
