Cm2250 boost pressure fault

[1776trucking]

Looked up on cummins insite for part number exhaust back pressure sensor part # 4928594
It's located right next the delta-P sensor not located where the pictures points out.

That is incorrect!!!>.

That big green arrow, and the component you removed in your last post(s) is the EGR Pressure sensor!

the picture I posted is the correct location of the exhaust gas pressure (exhaust back-pressure) sensor. ..

Don't know the part number off the top of my head,.. have not looked up the part number. Account on quickserv has recently expired and I haven't bothered to go through renewing it yet.

Is this guys information correct? What is the proper location of part number 4928594, and does it change from the cm 2250 to the 2350? Quick serve seems to show it next to the Differential pressure sensor.

That IS a pressure sensor BUT IT IS NOT THE EXHAUST GAS PRESSURE SENSOR!!!! - THE PART LOCATED AT POSITION # 39 IN THAT DRAWING IS THE EGR GAS PRESSURE SENSOR!!!

Looks like the video was taken down. Couple questions. I'm in the process of doing an Egr tuneup per your recommendation (230,000 miles). IMAP was clogged,doser was clogged, and dp sensor looked horrible underneath. Would you suggest replacing the gas pressure sensor, and the exhaust gas pressure sensor? I also can't seem to find the correct part number for that exhaust gas pressure sensor that is located on top of the thermostat housing?? Thanks for the help on this. Truck was not showing any codes I can only imagine what would eventually have shown up.
