High exhaust pressure

[lwilder27]

On the ISX12 the pressure sensor tube is on the back of the manifold and runs up to the mounting for the EGR cooler. It does not go through the thermostat housing. They are similar in the fact that there is a small passageway from the tube to the sensor. I cleaned that as well and blew air through from the sensor hole out of the new tube before I put the manifold back on. All is clear there.
