I have problems with these 2 errors P1206 and P1113. The engine does not always have this problem, but when it has it it oscillates a lot the rotations per minute and when the rotations decrease it makes an ugly sound if I help with acceleration sometimes it recovers other times it does not recover. ), I did the injector return test and I repaired the injector 1 and 2 because they gave more diesel on the return, the others very little and exactly the same 3 and 4 so they are good. I also changed the fuel pressure sensor on the fuel rail, the same problem, now I have to change the high pressure pump. I want to point out that I did not have a fillings at all in the pressure regulator when I replaced it with another one, so the pump did not have a fillings or flakes gold.

Hi

What are the two lexia reports for each of the two codes you have.

One screenshot for each code (not a photo) and attach them like this

P1206 Transient fault, Diesel high pressure regulation circuit Regulator control fault

P1113 Transient fault, Diesel high pressure regulation circuit Maximum press rail pressure



I would say that your P1206 could be causing the P1113 fault.

Look to fix the P1206 and P1113 will disappear.

'high pressure regulation circuit Regulator control fault'

What electrical voltage should the pressure regulator receive in the connector?

Sorry, I don't know. Is there any more information in lexia you can find, including the tests to do and the proposed solutions. There is often quite a bit of help for faults inside lexia.

And where can I access that section in the lexia? I haven't discovered it yet :roll:

Do you have a tutorial, something? :?

If you do not have the option, it may not be available to your diagbox version.

The lexia information topics are here.

There is no tutorial.

I come back again, I haven't been able to solve the problem with code P1206 and P1113 yet.
So I found that P1113 is due to P1206 and P1206 is due to a high pressure regulator control problem.
I leave below 3 videos to see how the problem manifests itself live on lexia.

Part 1 where towards the end at idle the pressure rises and the engine does very badly if I accelerate a little it sometimes recovers sometimes not.


Part 1: https://youtube.com/shorts/djQ3AA_JzGU?feature=share

Part 2:https://youtu.be/y_wTDEzXxEQ



Part 3: https://youtu.be/oJmPo0gz-dU

I mention that the controller is new, I measured the value of the power connector of the controller with the ignition on and I received a value of 9v. >>
