EGR edc16c8 the Alpha and the error p1238 mass air

[matech]

once deleted from electronics, you mean?

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

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...

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.
