Here's the situation. Vacuum going into the evrv is 15. Direct Scan shows the chip is commanding the evrv to apply vacuum while cruising. I'm test driving with a long rubber hose attached to the other port on the evrv and a vacuum gauge in the car. No vacuum to the gauge. Not setting a code 32 so the ecm thinks it's working. I need to get the egr working for inspection this month. Any ideas on how to check the evrv? I don't have access to a spare. Thanks.
 
found the problem

That $100 for the shop manual paid for itself again. The pnk/blk that's supposed to be 12V with the ign on was actually grounded! Clipped it and hot wired it for a test run and everything's working fine. Now I just have to hunt down one shorted wire and a burned up fuse link. Oh joy.
