guys I have a stylus that does not push you do the diagnosis, and there is a lot of errors including also the mass air flow sensor control the parameters of this and the mass air objective, and your far from the measured, therefore, that the poor yield and the smoke depend on this gate errors and it remains in memory p0251 (fuel pump) and p1604 (main relay that is not clear but the machine part and in addition to the poor yield has no problems what can it be ?
when my teacher of electronics at the time was wondering what could be the problem and I was always ripsosto " and a failure!".
jokes apparently are 2 different problems.......I would start with is to revise the pump......
If the values read from the mass air flow sensor are not correct, I I would like to start with the controls from him the same:controls that do not have sucked the air filter,that does not have the retina, which I know is in the support of the mass air flow sensor was blocked,and then checks the mass air flow sensor the same with the piping on the suction side
for the yield check, the egr valve, on the contrary chiudila with the sheet metal and remove it from the map.

first of all thanks for the responses for the yield is the mass air flow sensor because I disconnected and now makes twice the first so it takes nuovp the proplema was the error P0215=Relay power supply that I can not delete because it returns instantly
I did resolve by reviewing the pump....it will be a defect that is similar....this, and how often the dtc can be deceiving.
hello joseph nn gives you information about which relay is that?Originally Written by Giuseppe2016
