Technical Problems with Ducato 2.8 JTD (244)(2003)

[charlesgraham]

Ducato motorhome giving problems, engine management light comes on very briefly and vehicle looses speed, intermittent fault.

Have error codes as below:
P1555 Accelerator brake feasibility
P0609 Sensor power supply 2
P0220 Accelerator pedal sensor 2
P0235 Supercharging pressure

Do the forum members think these are one fault or different problems,

Advice gratefully requested.

As a supplemental, where can I get the wiring diagram for my machine.

Your turbo waist gate actuator is seized onto the lever out turbo causing p0235 common fault

First thing is clear the codes and see what comes back immediately after it happens. Some codes could be a once off eg after van standing for a winter wasfegate could be stiff. Brake switch has two outputs as does accelerator pedal either could cause those symptoms.

Engine management light coming on intermittently would point to EGR sticking/not operating correctly but Turbo Wastegate Actuator as said would cause same pickup by sensor so check actuator first...

 

[corcai]

Egrs in the 2.8jtd are very rare I've only ever seen one in the panoramas.

Yes that's ok Corcai just mentioned that had a few vehicles with flickering management light and it was down to EGR either blocked, sticking or solenoid not operating it. That's why I said to check linkage. My cars got that problem and only thing unchecked is for turbo actuator linkage and blockage to waste gate...

Did you get an answer to your fault Charles...So we can remember answer for others...

 

[charlesgraham]

Really no, I when to the main Fiat dealer in my locality, he diagnosed the recurring faults, as listed above, but could offer no solution, said it might be a bad wiring connection SOMEWHERE, and I could leave it with him to look see , but it might take 1 hour or all day to possibly find the fault, that’s at around £80 per hour! If he couldn’t then find the fault the next step was to change the ECU..for around £500 plus, plus..So had to decline that..My next choice was a local mechanic, who said it might be a fuel type problem, so he changed all the filters, indeed did a full service, and the current position is that the problem has gone, hopefully permanently. So now I drive with my fingers and everything else, crossed...

 

[goggs]

Sounds like air getting in the fuel system then. Possibly at the fuel filter where filter bowl or canister hasn't been secured properly or O ring twisted or missing. Tank running empty ? Joint on pipework ? Diaphragm cracked at plunge filter...Do these engines suffer from any of these traits as my car does..

 

[charlesgraham]

I appreciate your input, have been reticent about driving too far after my tale above.But today I went a massive 30 mile drive , with trepidation, and not a glitch on the whole journey, so hopefully !!!!

 

[goggs]

Yes you should be OK now...Head for the Sun...
