EGR off 1.3mjet does it really work?

[Backgroop]

do a test ,remove the solenoid valve from the body, egr, leaving it attached to the connector, and the machine is in motion to a minimum, and see if it is open and how it works, the pivot of the solenoid valve.

Gi? tried the valve connector unplugged, it is closed, just makes me ? arrived another 500 in the workshop with problems with the EGR now I try to exclude it to verify the behavior

Try and keep us up to date....
I usually get a small plate between the radiator and the egr cos? I do not exclude that the shots still in the manifold....

[ugoboss]

perhaps, then, it is that 3% that does work to a minimum.

[sportknight]

as I said,there remains cmq slightly open...

[baraldino]

with diagniosi to a minimum the mass of the air changes with the connector unplugged?

Just finished the tests on a fiat 500 1.3 mjet 75hp, the result in the diagnosis percentage opening egr valve "2%" was the EGR off, the EGR valve remains fully closed, is not controlled at all.. I attach the modified files:

On the other 500 to work around this problem I had to remove the plug and insert a resistance of 36 ohms with a tolerance of 5%..
I do not understand why out in the same way, on one works on the other no..
pu? depend on the software version??

[ugoboss]

may be, on the first you had made other changes besides the egr?

Yes, the exclusion of the DPF, but it does not imply something in the management of the EGR.. I did the test to put the original map only with the exclusion EGR but still the same problem.. and also I checked in my database and this version of the HW and SW I have made so many.. and they do not have ir? had no problems, that is the ecu damaged?'

[megamind]

I do not think that it is the ecu damaged, maybe try with the exclusion also of the dpf if d? the same problem.

I have noticed that on some cars 1300mjtd I are 0% other 2% other 4%, the values from the diagnosis.
