Default What DV? What maintenance have you done? Have you verified it's in working order?

If it's a diaphram style the diaphram could be torn. If it's a piston style then it could need cleaned and lubed. OEM DV's are fairly cheap, could throw one on and see if the issue is better, then if so the dealer should be able to look into something else.

Default put in the OEM DV...clear the codes and see what happens. less variables helps to diagnose

the problem areas.
