Fuel injected. Just two questions. Does the DP need to be replaced if the rubber boot is gone and where is the vacuum coming from on the lower VSV hose. The place where it is plugged into only has a small pin hole in it. Thanks to XXX. Great help.????????????????
why replace good parts.?
do the tuneup in the book (60k miles is the majors)
you sammi failed the pinch hose test. sure. easy that relic hoses. and all.
no hose is designed for over 10years, in service.
how ever EPDM hoses might, upgrade to them or if flush with cash silicon.
DP that is a dust boot, its ok , let it run .
i do not kwow where PLACE is.
only photos work,
if in he USA , are you? open hood look up.
see white sticker vacuum map, that is the vacuum routes
the vsv has 2 hoses.
and is polarized. that is right, if the valve has that ventcap and filter
it is polarized.
so the hoses cant just be fitted by guessing
when the ECU drops out the DP.
the valve closes, the DP side switches to , VENT.
if not the DP hangs do to trapped vacuum in the DP side.
the DP tests are simple. ih hand.
pull 8inchs hg vacuum must hold on scale for 30seconds or the diaphragm
is cracked. (a double failure bad DP and vacuum leak )
the make sure the rod moves from min to max, no vac then 9 inches/
that be a good DP.
on car is more test.
pre the fsm. start car, in less than 30seconds the DP retrackes (sucks in)
and stays there full time runining.
the vsv 101, its on my page , search VSV.
not broken or holed VSV parts, or cracks , missing nipples
it must close. 0v
it must open with 12v. (some work backwards from this)
it must not leak closed.
its just a 12v solenoid air valve.
open coil. or shorted coil.
