As in the subject of the problem with the throttle, a new control module was replaced in it but unfortunately the error P0638 is populated - THROTTLE MOTOR SHORT TO GROUND. I am waiting for help.

The module itself? Look at the harness, especially the throttle plug.

Daniel _91 · Answer

The module itself has been replaced, and the entire damper has been thoroughly cleaned. Added after 11 :  The module itself was replaced and the entire damper was thoroughly cleaned.

Daniel _91 · Answer

The bunch with the cables has been checked, everything is ok. Any ideas?

dabu · Answer

Look in the fuse box, under them a wide ankle, disconnect and look closely at the pins and cables whether they are flooded and rotten.

Daniel _91 · Answer

We are talking about a fuse box where they are inside the car?

Karaczan · Answer

No, the one next to the left lamp, in the engine compartment.

I connect to the topic, I have the same problem with iveco daily 2.3 hpi 2007, the same error, throttle exchanged and there is still a problem. Does anyone have a schematic of the engine driver? in order to check wiring, autodata, tolerance data do not have a schematic in the database and idc4 has a schematic but it does not match the throttle control and egr because they are on solenoid valves and here is a throttle.
Is anyone able to help this scheme?

Daniel _91 · Answer

The wide ankle was checked, I did not notice anything disturbing. Besides, it would be very strange that in the car from 2009 cables could be rotting

Karaczan · Answer

Rot and in newer ones because Ducato and Boxer have a small factory defect and can be full of water on these bundles. To check the wiring of the ECU throttle, not just the ankle itself.

DoctorCar · Answer

Everything is nice, but to the new throttle, if there is one after the modification, you need an adapter between the plug and the throttles, because life will not work

dabu · Answer

What are you talking about? If the throttle is ordered by the body number, then it comes with what it should, even if the engine is specified, and the plugs match.

MobilTruck · Answer

Exactly, after the change-over throttle has a different plug and you need an adapter which costs about 160 PLN. Photo from the adapter:

gori92 · Answer

There is someone able to send me a diagram for such an engine because as I wrote earlier the scheme of the engine in iveco 2.3 hpi does not match the throttle which is the same in iveco as in ducato 2.3 mjtd. I have such an ankle (black - as above put in the picture)

jaek1970 · Answer

Exactly how colleagues write above - new throttles - new adapter now 160 - some time ago I paid 600 in carserw ...... August. Regarding decay. It rot and rubs everything - especially on the bulkhead wall.

DoctorCar · Answer

For posterity, here's the throttle adapter scheme. greetings

gori92 · Answer

the adapter scheme is a will throw someone diagram of the engine driver or give the pins from the controller to the throttle output?

jaek1970 · Answer

At this moment I do not give the lap to me - possibly tomorrow, taught breakfast around 11 in breakfast hours

gori92 · Answer

ok jaek1970 I will be grateful for the schemacik.

fabio9999 · Answer

I have the same problem mentioning 2 days ago the recharge sensor problem was lost but after 2 days again there was a lack of power what to do gentlemen, I have no more power

Skapo88 · Answer

Hello everyone, also please help me with this situation everything played until the timing, whether it is a mistake when folding the car and the problem only with the plug

Qwai · Answer

I confirm what @DoctorCar wrote
After transferring the pins in the plug according to the drawing, the Pierburg throttle instead of Wahler 7523D works, there is no error :-)

In addition, I am posting a photo of the plugin with superior Pins

@DoctorCar thanks a lot for your help!!!

DoctorCar · Answer

No problem, glad my advice helped. Regards
