how can you test a bad egr sensor?
my truck threw up every egr related code in the book at me so could it be just a bad sensor? the o2 is brand new the cats not clogged i tried to clean out the egr with some carb cleaner still every code in the book

Did you take it completely apart and clean it? The rod might be seized not operating throwing the code, you can also look up testing it you will need a multimeter.

i don't know how to do that...
I have not taken the thing apart completely i plan to do that this weekend starting tommorow if its nice out the reason i asked was because i didn't find anything on the forum about testing the sensor itself the search feature is complicated.

Remove the EVP sensor from the EGR valve, use an ohmeter as called out in your manual. The pintle needs to be pushed in and out to obtain different readings.
Remember, with EGR valve removed, there are two holes esposed, one from the exhaust and another going back to the intake system. There are alot of reports about these holes getting plugged up.

What's the trouble here? Am I not being descriptive enough?
Do you have vacuum in at the control solenoid?
Do you have vacuum out at the solenoid? Should be none at idle and see what you get when you play with the gas.
Does the EGR move when vacuum is applied? If you don't want to suck on the hose then use engine vacuum, borrow the supply from the solenoid or something.
Then I would start checking wires and signals and crap if all that worked.
