RE: Purge air actuator code 3225, spn 3490 and an air dryer
I've been meaning to get back here but, I've been pretty busy the last few weeks.

Since having this truck, about 2 years, I've changed the dryer cartridge a few times. The beginning of March I changed it along with the leaking purge valve. Maybe disturbing the purge valve loosened up some gunk inside which plugged the Aux ports? I guess it doesn't matter now since the dryer has been replaced.
