Technical Fiat Ducato 2.3 Multijet - P0105 code

[daverally]

Hi All,

I'd like to ask your support in the following topic:

Car details: Fiat Ducato 2.3 88kw (year:2011)

Right now I have 2 failure codes in the ECU system:
- P0105 - manifold absolute pressure/barometric pressure circuit
- P0135 - Lamba sonda sensor - (it's totally clear , what is the problem, I have to change --> I'll)

I already replaced the MAP sensor for a new one (Bosch 0281006076). The failure code is same.
I also replaced the Air Mass Sensor (Bosch 0281006048), but the failure code is still same.

I think it's also imporant to mention that, there was a motor renovation, when we changed a lot of things, like: chain, timing belt, bearing, injector, fuel pump, valves, finger follower, cylinder head renovation, all gaskets. All of them are new , and still quite weak and there's a big smoke.

Currently I don't know what is the issue. If you have any idea, pls give me advice, what cause this problem.

Thanks a lot.

I experienced MES not being able to remove error codes even if the software stated they where deleted. AlfaODB could erase the same errors which MES couldn't. What software are you using to delete the codes?

You have mentioned changing quite a few things. In MES section F7 adjustments there are a number of options like relearn or adding new sensors (inc MAF )that you may need to do.
MES give the MAF as part OE HFM6

Number	HFM6

Hi,

I'm using MultiEcuScan, but I try to delete it with another code scanner.

Hi,

I'll try out but i disconnected the charger cabels, and I though that it will forget everyghing, but the error code is still available.

Could you make a screen shot with the freeze frame data?

I checked your proposal and the problem solved
I had to go to relearning section in MES section F7 adjustments and I could set. Now I got back the missing horse powers.

Thanks for letting us know that in the end it was just reprogramming the ecu with all the changes made.
