Sensor Cleaning
Stupid question time 
Just want to get it all in one place for posterity and all
Cleaning sensors:
EBP: Remove sensor and remove carbon carefully with string trimmer line or straight pick (don't puncture diaphragm). Remove tube, spray with carb cleaner, and "rod" out with string trimmer line.
MAP: replace hose. Clean sensor carefully with something soft, q tip and no chemicals?
MAF/IAT2: spray with MAF cleaner. follow instructions on can, maybe clean element with 90% isoporpyl alcohol on a q-tip carefully
BARO: leave it alone?
IAT: spray it with MAF cleaner. typically replace if it's really causing issues?
ECT/EOT: spray with alcohol to remove oil. swap or replace as needed
Cam/Crank: replace
ICP: replace

Other than Cam and Crank sensor or ICP, which I have no experience, sounds right to me. I have done sensor cleaning several times when problem solving a bad EGR. One thing I would worry about is your pick comment, on the EBP, I would not pick at it at all, only rinse with MAF cleaner and let air dry, it takes more shots of cleaner but it does come off and come clean, at first it just looks like it won't ever come clean. I have cleaned mine twice and it's still working. For what that's worth.

The only two sensors I will spray at is IAT2 and MAF , maf only spray and the consciences states brake cleaner , but I have always used Carb cleaner and a plumbers flux brush .
