EGR edc16c8 the Alpha and the error p1238 mass air

Hello all,

I have a survey to do:

I disabled the controls egr by mapping a total of about 5 edc16c8 of the Alfa group, 1.9 jtdm 140cv

a little run for more than a year without problems
but the last two that I did after a bit of time to generate the error p1238, relative to the mass of air sucked in is too high.
the contorlli EGR have been deleted, eliminating the four "flat maps" on this type of ecu... but I repeat that 2-3 cars go around a lot without this error...

I doubt that the error refers to some other problem, of course, but since all of the literature refers to the problems of the EGR, the workshops, of course, break the boxes to me :-D

unfortunately, the ******* it does not delete the individual dtc on this ecu....

any idea?

PS: also checked all the hoses and the heat exchanger, no loss...

email the file that there is a step to comply with

It had been only one, I would have thought of a problem that is not attributable to the mapping, but in this case.......
Can you post the file ori and mod file of one of the two?

If you do not follow this step, it seems to me that should not be even in motion. However, the poster? the file...

no bitchy egr continues to work

as he told his friend, except you'll want to post the file, maybe you ? missed something

email the file ori, and I am there happened you have to touch the other map! ..also post the mod!

have you tried to reset the map of the swirl?maybe they are the ones that you create problems of air into the manifold and the ecu gives you that error

I have not seen the file
But me and success is always on edc16c8 ke was the electrical part fails and anke with the controls to zero, it gave error.
Electrical part to be replaced

success to me! Alfa GT, excluding the EGR from the ECU and the continued failure mass air... mechanical part ok, solenoid fault!

I agree with fidodido you definitely need to replace the egr because of the part in dustria l e lectronics failed.

however, right now another of our group, gs has made the same request on the same type of car and with the same error, but as you wrote you ******* does not support to delete the dtc,but to him we sent a ori and mod example of a fiat punto 1.9 mjet edc16c8 where ******* it works if you want we can do it as well with you and you get the idea.

I can confirm that it worked perfectly the file in my case...the error was p1237 but always have a

It would be perfect!

maybe from the sample file I can find the area to change also on the alfa.....

I look forward to the file via **** ;-)

the area ? identical slammed up, you can find definitely

Guys...? also possible to "emulate" the egr...just a resistor 39ohm, 10w dissipation;)

once deleted from electronics, you mean?

many of the ecu, as on this alpha, damage or other errors?...

hello I'm sorry if I quote now the discussion ,I made a gt about two weeks ago and I had to change the electronic unfortunately it was already burned sn arrived late,,,
pero looking at your file you made a mistake and you lospiego immediately lowered to 24-bit affixed 25-in fact I have done ?or the same error and gave me the same problem....
then reset 25 bits in the 4 panettone ? test the error is the.... ok....

Actually zooming I had noticed that the curve ends in the flat part, but the point is more in the l?...

but I always seen to do so?!

thanks a lot for the contribution, the prover? certainly.
