Got code 2366 today and it has to do with engine brake actuator voltage.Thinking that this code and the intake manifold pressure sensor voltage code are related.How would I go about diagnosing these issues?

The troubleshooting trees are all in the Isite program you're using. Have you gone through them yet?

You said it's a 2004 cm870. Maybe try tapping on the ECM while the truck is running. I think the recommendation is lightly with a hammer? (Someone correct me if I'm wrong) Maybe seeing symptoms of an ECM going out? Could also be bad contact, corrosion or bad wires with the wiring harness or it's connector/plug.
Also, not sure if it was mentioned already, but you said it started after you changed a few sensors. Might want to go back and make sure each of the sensors were plugged in fully and correctly, check the plugs for corrosion or anything else that might short the wires or interfere with the electrical circuit. Finally, you can follow the steps in quickserve/insite for troubleshooting the sensors using a multimeter. I would check all the new sensors in addition to the ones throwing the errors.
