View The Full Version : Error P2112 - motorised Butterfly Bravo 1.9 120 hp

kekko

Good evening,

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.

kekko

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?

Grz for the explanations

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.

booster

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)

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?

dariuccio

but on a diesel, what is the function of the motorised butterfly? ? can that diagnosis you d? the butterfly, but the fault is somewhere else

Tinturia

controlled in the appropriate manner, sequentially generates a depression that facilitates the entry of exhaust gases coming from the egr valve

helps you to manage the temperature of the combustion necessary to the strategy of implementation of the DPF;

avoid the vibration of the engine to off,closing completely

Quoto in full.
Have you tried to do a forced regeneration with another tool of diagnosis?... you alone during regeneration?... maybe ? an error induced by a wrong setting of the forced regeneration...

Tinturia

Excuse me, I better re-read the post...I misunderstood... I thought I was doing a forced regeneration.
I think the advice given so far is pi? that is correct.

watch kekko!!! I 2 days f? I had the ostesso problem with the same machine I have not used it aditivi and luckily I didn't have to disassemble anything !!!! to do so, just buy a cleaner in the throttle body that would be around 15 euro disassemble the intake pipe that goes to the entrance of the throttle valve and the engine is running spray a mild dose of the product ,while the spray you have to give the strokes of the accelerator so that the plant intake clean for good ... clears errors stored in the ecu, and see if it reoccurs again .

Test with additives professional..then if it works do close the egr..to remove the manifold and clean it physically it takes a lot of time..

on multiple with the same motor was burned out the control board, and even if it was opened was to see to the ecu as open to 5%.
As a consequence, to idle the engine does not saliva + 2000 rpm and the road was + strong if you got up in the clutch, do not accelerate.
I solved it by removing the plug, blocking open the valve and eliminating the dtc, now at least the car goes as it should go. Being next to the board, the owner did not want to spend money more? the need to pull forward.

Hello Alessio. C'? there are a myriad in circulation. What brand did you take? Was it a spray?

Alessio93

the brand of the product was petro chemical used fiat as a cleaner
