Technical crankshaft sensor camshaft sensor location

[theoneandonly]

As description where are they. 2017 twin egr 2.3 Duc
any idea as to voltage crankshaft 5v camshaft 50V ?

Whilst there is obviously a possibility that the location and specification has changed for the later engine(s), there is detail which is probably still relevant on pages 71-73 in the Ducato training manual available in the downloads section here.

Thanks,
Im out an about so no acces to my cd a laptop and being this is a "new tablet" not everthing is downloaded.or i cant find it.
A quick look shows i can find info relating to chain drive cam 3.0l but not belt. Time to put kettle on again. Stuck at MIL so i was hoping to prepare for some testing , now appears to be tuesday.

My bad. There are two manuals under the same download page, and I've linked the wrong one (that relevant to the 3.0)

Try this:

Must remember to delete the wrong one.
Thanks for links now comes a terminolgy question. I am trying to analize my injectors with a picoscope and taking advice from elsewhere. it suggests measuring the crankshaft sensor and injector then some maths together to find the "different cylindar". Now is this the camshaft sensor on top "timing sensor"
or the engine speed sensor "revs sensor" (used to determine the angular position of the crank)
as i write this i'm begining to have an idea but someone me or him was confused when talking about the rev and crank sensor as 2 separate devices. its the same one? please unconfuse me.

I'm pretty sure the revolution/crank sensor are synonymous.

Though the following is actually from the other training manual for the 3 litre engine, the need for both a timing and revolution sensor is neatly explained, and is probably similar for the 2.3. (i.e. on first cycle or part-cycle, the initial cylinder for injection is determined from the timing (camshaft) sensor and once that first (part-) cycle is complete, the crankshaft (rpm) sensor alone is used).

@HughJampton Thanks for the clarification.
now makes sence the originalexample trace had both.

The above is also stated for in eLearn for the 2.8jtd, but I have been unable to find a similar definite statement for the 2.3, either in x250 Training Manual, or in eLearn for the 2.3jtd.

Thanks gents will be Tuesday now before i get a chance to play. If i get anything sensible you will eventualy get to see it.

from eper from an x250
on the x290 there is a bunch of connectors in the centre next to the turbo solenoid dymax unit any idea which is what. ps forgive spelling

I think i've eventually found it. Certainly not obvious tucked in behind oil filter or easy to back probe.
