engine fault light on limp mode fault code P2563 (1 Viewer)

[Newfie]

We had a problem today on the M4, engine fault ON & in limp mode. Pulled into the first services & called the RAC who checked the obd & cleared the fault code P2563 Turbocharger (TC) boost control position sensor - range/performance problem.
This worked fine for 2 mins & has now reoccurred , so drove home very slowly
So has anyone seen this & how do I rectify this problem.
It’s a 2016 Fiat Ducato 2.3 150 hp euro 6 engine.
Thanks for your help

Did a Google search "how to rectify P2563 problem on a 2.3 ducato" and it came back with a couple of thread that might be worth a read.

Maybe turbo actuator sensor sending wrong info to ecu.
Could be any number of things causing it.... Chafed wiring, mass airflow sensor, failed turbo sensor etc.
Needs a Fiat diagnostic computer to narrow it down.

Thanks for that, I have googled & found the same links. It’s only done just over 6000 miles & had a full service in November. I will try & check out the wiring & vacuum tubes to the servo tomorrow if I can find it

prone to the small hoses splitting where the go on to joiners

 

[jockaneezer]

Had a similar fault code on our son's Combo van, intimating a turbo boost issue , and it was one of the small vacuum hoses which had pulled off a tee piece. Worth checking the simple things first.

My money is the small hoses as well...................

 

[Newfie]

Ok so checked all wiring & hoses I could get too, reseated/fitted were possible.
I still have the engine warning light lit.
It might need to be reset again. Does anybody have or can recommend an obd2 reader that I can reset my codes. Loads of cheap options on eBay but are they any good?

I had this fault on my Landrover Defender and turned out to be a gunked up MAP sensor. I just cleaned the sensor bulb in carb cleaner and cleared the fault code, no issues since.

I have the same base vehicle and this works well - Carista OBD2 Bluetooth Adapter

Ok thanks for that I’m not sure there is one on the fiat, or if there is I don’t know where it’s located

 

[Lorryman100]

It will be on the inlet manifold and as long as you have a variable vane turbo then there will be a MAP (Manifold Absolute Pressure) sensor.
Give me a minute and I will see if I can get a pic from my van which is the same 150bhp.

If only it was that easy to get to, not a lot of room under the bonnet of a fiat.
I had a look but unable to see it.
Looks like a trip to the local dealer or garage.

I cant get to it from above in an A class to get a picture. Not a lot of room,lol. A diagnostic tool capable of live data will narrow the fault down pretty reliably.

The only loose pipe is this one ,it has a clip, but not sure what it clips to.
It connects to some sort of valve showing in the 2nd pic

 

[jockaneezer]

That second valve looks like a vacuum line solenoid. There's usually a couple of them, with one being used to control the variable vane turbo. If it has a pipe going into it and one coming out of it, it should be ok as long as the electrical circuit is ok. I had one on my last Volvo where the wires to it wore through and blew a mini fuse in the main fuse box, this showed up as a turbo boost fault.

 

[Larby]

That's the solenoid in the centre of 2nd picture, that's what controls turbo boost.
Only a rod and a coil which draws the rod back and forth. My rod rusted up in the winter.

Update I have now got the OBD reader & there are 2 codes showing
P2563 Turbocharger (TC) boost control position sensor - range/performance problem
P0238 Turbocharger/Supercharger Boost Sensor A circuit high
So possibly a electrical fault
Can’t check further today as it’s been raining on & off all day

 

[Newfie]

Booked a mobile engineer to come & check on Tuesday next week

I had a similar problem to you about a month ago, and it was the little white blanking pipe on the Dytech 460 unit (picture on thread) which had developed a small hole. Temporarily fixed with a bulldog clip and super glue!!

[Newfie]

I did see that thread & checked all the connected pipes for leaks but couldn’t find any.
Did you remove the Dytech to get to your leak?

 

[moulin 87]

It was a small hole in the in the white coloured blanking pipe on the front of the unit...

Lastest update, mobile engineer turn up but he was unable to read the code on his laptop. So I had to take it to their garage. where they checked all the vacuum pipes (already did that) found & checked the map sensor says it looked like a new one with no dirt at all. The sensor is located behind the the cab fresh air intake cowling which had to be removed to get to it.
Electrical connections checked no probs found
Reset code & tested turbo All ok.
But same fault when occurred when driving.
Possible electrical fault or eco further investigation required

 

[Newfie]

I had to take it to the local fiat garage & finally fixed
Ok so now a happy bunny we have the MH back it was a faulty Turbo Electro Valve replaced £47.39 plus vat.

We had the same issue having just picked up a brand new van with no miles on the clock. Went into limp mode and we drove 240 miles home. Took it to the garage , took 2 minutes to fix. A pipe had become separated, sorry can’t remember which one but it was no problem.
