can someone please confirm the correct wiring for the sensor ?
Do not have 12v+ at sensor ? i am sure this cam sensor needs 12v but can someone confirm ? vehicle has idle issues any help would help cheers .

Are you fault finding or splicing?
Sometimes sensors are fed with 5V not the full 12V (eg. TPS).
This is not for sure though in this case.

have problems with P0341
cant find a wiring diagram for the KFU engine which its fitted with a marelli ecu .
anyone shine any light on it .
thanks for your reply v9977 .

Give as much detail of the car as possible so people can help more easily.

They run a cam sensor in the coil pack, via wasted spark ignition. But camshaft sensor is also the referal name sometimes for the crank sensor on the gearbox

am needing a wiring diag/ecu pinout for a 16v 206 kfu engine code .
its got a crank and a cam sensor has a delphi coil pack .
It also has vvt ,which increases valve lift i think .
car runs at fast idle but drives poorly eating a lot of fuel but this may be due to the fast idle 1800! but lugs off the peddle when driven at speeds under 50.
no mil and code p0341 prevalent.
yes p0341 can be produced when a coil is being used as a signal reference point on a waste spark system but if this is being utilised i dont think a cam sensor would be present .
anyone got the pinout 
am pretty mechanical minded and have a wee dable with the electrics but i just cant get the dam engine diag/ecu pinout .
or someone who is familiar with this engines electrics

Sorry I thought you was refering to the 8valve alternative. I would personally just say its a et3, what more do.you expect?
Management have never liked that as an answer....
I'm guessing youve changed the sensor and no luck? Whats the actual fault code explaination? Ie what does p0000 mean? Cba to look it up 
If you do despretly want a diagram to check resistance, I will need your last 8 of your vin

sorry Addaz ...et3 it is then
yea sensor been changed and no different if the sensor is disconnected when running it makes no diff to engine .Now got a permanent mil light so will have it read again .
have PM,d you my last 8 vin and a wiring diag would be most helpful .
many thanks

If it's a Hall effect sensor then it will have 3 wires-
supply
signal
ground
If it's a 12v type then it will be
supply 12v
signal 5v
ground
Some people say
"There's 5v on the signal line when the engine is stationary" Well it will be, the 5v is a carrier signal and the signal will change abruptly when it senses the cam so it will be an irregular square wave output. To view that then you need a scope as a multimeter won't be fast enough
If it's a 5v sensor then it will be
supply 5v
signal around 2v
ground
and similarly the signal will be pulled towards ground
With the MIL lit then you will need to erase the code as it will ignore the CPS and possibly not supply voltage to it until you do
Some cars can run quite happily without the CPS if it's used mostly to detect which cylinder is on compression for ignition at start up. Other cars perhaps with VVT really need the constant information from the CPS
P0341 is a CPS performance problem so it's losing signal/signal doesn't match with expected so a scope obviously would enable you see exactly what the ECU is flagging
When you haven't got a wiring diagram then a wire tracer, similar to those used by telephone engineers, enables you to track the wire and also detect any open or short circuits along the way. It's a quicker and more accurate way to find ends of a wire through a wire bundle than studying wiring diagrams
Note that a 5v supply voltage can be affected by anything else on that same 5v supply rail eg air con pressure stat, MAP sensor, TPS etc

Thanks Deckchair5 helpful info .
like i say car has been read and that was only code that was present but i will do another read as things have developed with the mil now on ,have already tested the wiring between the cps and the ecu for continuity/resistance and it checked ok .
the sensor(when disconected) does indeed have 5v when stationary but also has 4.6 volt and nothing on the red wire ,had a look at a Citroen diag for similar engine and ecu and it showed 12v for the cps ,hence my question but until i see the correct wiring diag/ecu pin out i could not be sure .
thanks and i will do another code read ,
any chance of that wiring diag Addaz ?
thanks for all the replies .

mil was on because of the messing around i was doing with sensors disconected ,had not erased dtc,s after messing around ,once erased the only code that came back was P0341.
Back to P0341
had live data read and the IGN timing #1 is between 49 and -15 all over the place and i am wondering if indeed P0341 is indicating a faulty coil pack ? its delphi but the vehicle does have njk plugs fitted so maybe this could be the answer but just a guess tbh .
once the codes were erased vehicle has been run but like i say nothing else there just P0341.
* earlier on the thread i mistakenly called the dtc P3041 INSTEAD OF P0341 ....sorry
P0341 IS CPS RANGE/PERFORMANCE ...is it poss that this code is referring to the reference from the coilpack and not the cps ?

The P0341 is stated to be referring to the camshaft signal. Is the ignition timing still as wild with the CPS disconnected?
Is it misfiring?
Does the MIL come on soon after starting once you've cleared the code?
Are you able to retrieve any freeze frame data from the code?
If you have air con try disconnecting the air con pressure stat as a test. Sounds daft i know but they are often on the same supply voltage rail. It'll set a fault code but at least it's eliminated then from affecting the other sensors

The mill only came on after i was disconnecting stuff earlier but upto then it was not on and has now stayed off since dtc,s been cleared .
just p0341 present.
will test again with cps on/off but it makes no diff to the fault but will check again on live data .
not misfiring as such but popping when foot is off the peddle and revs dropping from 3k-2k ...like timing well out (retarded ?) although it runs at 1500 it when driven if any load applied it dies slightly but then picks up .
will try with a/c pressure stat discon ...thats low press switch ?
and see whats its doing on live d .
the timing info i gave is values ...not degrees so might try a timing light on it and see what its saying ...maybe worth a try .
ok and many thanks ...will report back .
cheers

Yes that's it. It's on the 5v rail and can interfere with Throttle, MAP, crank sensor and cam sensor
If you clear the fault, disconnect the CPS (as your car runs quite happily without it) and then see if P0341 reappears with A/C pressurestat still connected then that would be interesting. I would expect to see cam sensor open circuit fault code but it'll be curious if P0341 appears
What year is your car?
had live data read and the IGN timing #1 is between 49 and -15 all over the place
the timing info i gave is values ...not degrees
You say this was "values" ? What is it you were measuring there? A coil breaking down can spike everything in the system

Hi my name is Martin and I have exact the same problems with my car like author of this post I mean high idle revs then p0341 and p0010 permanent faults and tbh can't find any solution and try I guess everything so my question is anyone found solution of this problem??? You help will be much appreciated and very very helpful..;) so wait for your answer please. Martin
