Please help Paccar

There are no codes on the laptop. It did have high exhaust gas pressure. I'll check the sensor & tube as suggested. Thank you.

 

Where exactly is the exhaust manifold pressure sensor/tube? Is it in the BPV?

 

In 2019 Paccar issued ECM updates. This truck was updated at that time. My understanding is that there were issues with the update that caused the problem I'm having. Post update is when my issue started but far less frequent than currently. Deleting it exaggerated the issue. Delete software must reflash back to factory VIN setting in order to remove faulty update. Sounds reasonable to me. Anybody else experience this?
