Error P2112 - motorised Butterfly Bravo 1.9 120 hp

[kekko]

Good evening,
I have a fiat bravo 1.9 120cv, Saturday night ? on light check engine that is annexed to the reduction of the power of the machine.
It is the second time that he has done, just before starting a regeneration of the dpf . with the multiecuscan I found both times the following error "Error P2112 - motorised Butterfly", which I have corrected. I'll post the links to the photos 1qui 2qui

Now I'm asking for advice on what to do and if ? happened to someone.
The motorised butterfly needs to be replaced? You can proceed to clean it?
If I have to go to a mechanic I would like to go prepared, without being duped with unnecessary expenses.
Thanks for your time

First thing I would look at if in the suction line where ? attached to the butterfly, there is the dirt of the egr valve is that it does not work well.
Then another thing that you can see ? if, by chance ? positioned the electrical part for the below, open it, and that in its inside circuit is not full of oil ( if so throw )
if, instead ? everything is ok needs to be replaced

[beppe.c]

try to clean it up and see if you ricombare l error,I suggest you to close the egr ? the cause of the locking of the butterfly.

Then, in order, proceed with the cleaning of the inlet conduit. in the case where it returns the error we proceed to its replacement.
Would you be able to roughly quantify the expenses both for cleaning and for replacement/spare?
Also I can try to use special diesel or additives or are money wasted??

Grz for the explanations

[michele30]

I aditivi and special diesel not I would use them, they are just wasted money.
maybe I would do those cleaning or if you know someone who knows how to work on the ecu from your parts, made to delete the egr valve, and maybe make the mod even to the butterfly for not putting more hands, breast, put it all new.
I changed to a butterfly valve for a Gpunto 1.9 and it seems to me that the reconditioned was about 400 euro, but not prendelo for good why? ? the past of the time, but it costs a lot.

have you tried if it works with multiecuscan?

F6 actuators

lnlet circ. throttle solenoid valve(flow edit.)

This function is activated, the throttle valve to control the flow of the intake manifold. Please see:
- Ticking noise from its rel?
- The ticking of the valve
- The correct operation of the valve
- Changes in engine speed, and the sound or stop of the engine (if the test is performed with the engine running)

[kekko]

I will try in a week... What happens if active, the function?? Is a test to verify the correct operation?
I engine access on or off?

[booster]

doing a test run
opens and closes the butterfly
from the instructions of multiecuscan says the engine is turned on and off
I have always done with the engine off
test..

[kekko]

I made the test ? everything went well... What do you advise me to do? Some product to clean the intake and egr valve? The cost of the intervention to what might amount?
