Mercedes Sprinter edc17cp10 dof/egr file dosen`t work ?

Hi, i have here a sprinter with a edc17cp10, my file is a dpf and agr off file but dosen`t work, errror message pressure sensor.

Can someone check it and can say what`s wrong with that ?

What pressure ??? Exhaust Back pressure ???



This engine will not work without back pressure sensor , because turbo actuator logic uses back pressure as feedback to calculate VGT position. And boost pressure error after delete is direct result of missing,bad,or clogged back pressure sensor. We found it by our-self and did educated tuner on this issue (for some reason most tuner do not know this).

the b28/20 dpf pressure sensor.
Sensor is inside and work (without goes in secure mode 2000 rpm)

post ori too

that`s the ori
