They would be your Purge Solenoid,ASRV Solenoid and your EGR Solenoid....
Thanks Martin! That diag is missing from my manual. Printing that at work tomorrow!
What does ASRV stand for?
It is missing because you have a POS Haynes generic peice of trash for a manual.
Find an OEM Mopar shop manual set for your truck and it will save you money and time in the long run.
I like Haynes better than chiltons.
