Technical Engine Ctrl Faulty- shutdown

[joog]

Hi all, love my first decent car but it has a problem that needs to get solved.
I hoped to get a obd cable but my 2001 JTD but i found out eobd is supported on diesels from 2004 and newer so i don't know which "cheap" cable/interface i could buy.

Anyway, i have the Engine Ctrl Faulty error code, since i had mij multi i got the error about once every month or so but i only used it for 2 days a week.
Now i am using it every day with intensive mostly little freeway usage.
Since i use it daily i almost get the fault with engine shutting down every day of usage.
Usage is about 100 miles.
Mostly the engine shuts down, sometimes i get only the fault code with beeps.

I am still trying to find out why it does this but haven't got my finger on it just yet.
I think it does it mostly when i am accelerating in 2nd or third gear but i am not sure it does it only when accelerating.
I have tried many times to start it when still rolling but that doesn't work.
As soon as the car has really stopped i can start it like nothing has happened, only one time i had to try starting it for o minute or 2-3 (perhaps), seemed like forever but it wasn't.

I am not really a slow driver and think the egr isn't as clean as it could be but i can't say my car has lost a lot of power.
Even so, more than about 5000 revs in 2nd or 3rd gear are impossible to obtain, the turbo comes in nicely but the acceleration isn't as smooth as it should.
Why can the rpm meter show up to 7 or was it 8000 rpm when i can't seem to get it over 5000?
Anyway, even if it has lost some power it's not a problem, it's fast enough.
Maximum speed is about as promised by the manual.
Decent exhaust fumes, no fat black or white smoke.

Best bet would be.....

Must say i love my multi, it rocks and drives like the best.

Honestly it could be one of so many things producing this fault.

My advice is find (ask on here etc) a good Fiat dealership, speak to the DET & get the car sorted...how much better will you feel when its 100% working

Please dont go down the guessing parts route, you'll end up spending same (if not more) then getting it sorted quickly/correctly & be stress free

p.s. ignore limit on tacho

That's because the diesel in the JTD is governed to 5000 revs.

In addition to the previous post I meant to say the your problem with the engine shutting down is undoubtledly due to one of the myriad of sensors that exist on the JTD engine. Those that may be the cause of such a problem are the MAF, MAP & Crank sensors - in no particular order - I seem to remember the most likely one is the crank sensor and of course that's the one you have to replace whereas the other two can be checked. The MAF can be disconnected to see if it makes a difference and then cleaned if it has and the MAP can be removed and cleaned.

Still not solved yet and the fault happens very often now, with a cold engine too.
In general i have to admit i shouldn't take it into traffic anymore.

Readout says all injectors failed.

Going to the dealer next week, perhaps they can find it.
They will start with a costly diagnostic readout which i don't need anymore but brand specific perhaps they will know which hose or sensor causes this annoyance.

I recently had to replace the CPS on my multipla. When it went I got two messages, Engine Control Fault and one about the injectors. The AA guy suggested that the latter was because the ecu had shut the engine down and the injectors were starved of fuel.

In my instance the car would run for a few miles until hot then the fault with the CPS appeared and all power was lost.

£29.50 for the sensor from FIAT and a tenner to fit by a local garage.

I hope it will be the CPS but i can't say it only happens when the engine runs hot, mostly it's hot but...
If that would be the case i wouldn't be able to run the car when it's hot, right?
I most often can start the engine direct after the engine stopped, it seems i don't have to wait before it has cooled down.
Sometimes i have to try a couple of times because it won't always check OK immediatly but it does mostly.

On the dashboard i only get the Engine CTRL Fault.

I get the folowing fault codes on the ecu:

injector cylinder 2 failed
S.C. to mass
injector cylinder 1 failed
S.C. to mass
injector cylinder 4 failed
S.C. to mass
injector cylinder 3 failed
S.C. to mass

I suppose S.C. stands for short circuit.

Dealer didn't know what's causing this fault code.
They will check the wire and connectors and if they can't find it they think it will be the ECU.
All in all it would could cost me 1200,- without the guarantee the problem get's fixed
So any good ideas what to do next could be helpfull.
Thinking of replacing the CPS, just to be sure it ain't the almost cheapest solution, good idea??

Kind of ridiculous not to be able to use a second hand ecu, if it ain't the ecu i wil have thrown away 6oo,-:bang:

dealer shouldn't be guessing with your money, they have instant Fiat technical back up if they need it.

 

[the frog]

Are you in the AA?

I recommend their diagnostic service by the roadside. They got to the fault after trying a few things first (reg was the first one they checked but I've had that before and the symptoms weren't the same.

With the CPS it won't store a fault code, the AA guy had to run the diagnostic with the engine running to find the fault with the CPS.

 

[joog]

Not using the AA here but i would like to think if the official Examiner diagnostig tools can't find the problem some third party won't find it either.

Weird thiing is the fault hasn't happened the last 200miles.
I have a new appointment with the dealer in a week or so which should give me another 200miles.
If the fault still doesn't happen than wel...?

Just before i went to the dealer i high pressure cleaned the engine all around with the plastic cover removed.
I now ride without the plastic cover.
I think i also could have reached the cps sensor on the outside.

Perhaps the engine now doesn't run as hot as before the cleaning and/or because the outside temperature has dropped aswell, don't really know but it will be weird if i can ride another 200 miles without the fault kicking in again.

I wonder what to do:
If i go to the dealer they will check the wiring which will cost me about 300 pounds.
If i don't get that faiult, i think it's hard to pinpoint a problem on a car that hasn't happened for at least 400 miles.
Really wouldn't want to waist 300 quid.

I have ordered a cheap KKL interface which should work with unidiag, i hope i can use it on the road.

 

[the frog]

If it is the same fault with the CPS as mine it would restart after 20 minutes then drive about 30 miles before cutting out. It could be that my CPS had been dodgy for a while and that it was only found by a long trip. I only do 15 miles to work so it might never have ben discovered!

I would probably not want to spend £300 at FIAT either.

People, please be sure and clean your engine before searching for solutions.
It looks like my crank shaft sensor was so dirty from oild and dirt sticking to it that all problems went away after cleaning the engine.

Be sure it's all clean...

I can't find the CPS - where is it on the 1.9 JTD engine please?

Thx,

crank sensor? back of engine (need car on ramp)
