Hi all,

new to forum been watching for awhile thought i would join, had many of the probs with my 04 plate 2,0 jtd you guys have already experienced.

The latest problem i have if anybody can help is engine won't rev will idle and pull off & drive but won't accept any assistance from throttle just wants to cut out. It started late last night without warning lights etc, the egm light now decides to come on :bang: anybody shed any light would be gladly recieved from a very angry empty pocketed cabbie.

P.S. might have solved brake issue will post confirmation when i manage to get running again.......
 
Throttle position sensor.

Black 'D' shaped thingy on top of the injector pump housing. Check connections (plug) first.

Will try looking for that in the daylight cheers.

Have tried the throttle position sensor and that works fine, there seems to be enough fuel getting from the tank to filter but question is how much pressure does the injector pump then need (any way of testing all).

Vehicle specs are 2,0ltr 16v jtd on 04 plate, new turbo fitted 2 weeks ago, head gasket done over a month ago...

Have tried TPS works fine am running a bosch pump totally stumped :bang::bang: what types of code reader work with these blasted vehicles (tried one already but just said 3 general faults no code no's )

Tell the code reader it's a peugeot expert, that usually does the trick.(y)
 
I had this intermitant problem on my Ticked over at a slightly increased speed but no throttle response and EOBD light lit. After £300 spent at local Fiat dealer for plugging in laptop to tell me of fault codes but no cure I started to hunt round the engine bay myself. It only started to happen if it was damp. Some of the wiring runs very tight around the middle of the engine block and is only protected by some crappy fabric tape. I pulled this wiring away from the block and repositioned the insulation and some or the corrogated plastic the protects the straight runs. It ran perfectly for 6 months before I chopped it in for a new van.
Reset engine light with A £20 ELM code reader off Ebay.
Hope this helps.

Scudo 05 JTD.

but what was the actual fault:confused:
 
Hi all,
Well its been many weeks now several mechanics later with huge expense, Still the same problem. They have tried everything to and were all stumped only thing we can think of now is the ecu has gone tits up but am reluctant to spend mega bucks again to find it might not be that either... :(:(:bang::bang::bang::bang:
 
Difficult - somehow it always ends up as "its' the ECU mate....." when the 'experts' are stumped.

TBH an ECU either works or it doesn't. There is usually no half-way measure. Given the ECU has a miriad of inputs and outputs from sensors all over the vehicle the OBDII connector and appropriate computer should reveal any ECU problems - has the vehicle HAD a proper (and I emphasise 'proper') diagnostic tool attached? If so, and no errors are reported, then the ECU is fine - sve your money.

There is an EGR control valve that could be the problem - in my experience I managed to pull the pipes off it once (rubber hoses actually) and put them on the wrong way around. Result? No throttle, lots of white smoke.

No I'm not suggesting you have a white smoke problem but since the misconnected EGR valve caused a lack of throttle I'd be looking in this area.

All said and done - 'decent' mechanics should be able to resolve the issue. I'm constantly amazed at the general lack of ability of garage mechanics (given some of the posts in this section of the forum) but I equally don't condemn them all. Seems these days you have to be 'lucky' to get a garage with someone who knows how modern vehicles work....

<edit>

have a shufty at this link https://www.fiatforum.com/scudo/253581-scudo-2-0jtd.html. The last post shows a circle around the EGR valve. Follow the two thin hoses up to the top and a bit to the left - THAT's the EGR control valve I'm on about. Might not be the same on your vehicle but this is where I'd be looking.

I think the actual fault was a chaffed wire in the loom earthing on the engine block, only takes a little bit of earth leakage to send ECU nuts.
