Where is the evap purge valve located
SYMPTOMS OF BAD PURGE VALVE. HOW TO KNOW PURGE VALVE IS BAD
hey guys welcome back to auto repair
guys thank you guys for watching and
subscribing to the channel in today's
video guys will be a video that will
apply to any modern car guys nowadays
especially gasoline car so if you hear
one you will be very helpful to you guys
will explain what are the symptoms have
it published valve put a canister valve
okay this is the valve that brings guys
the vapors from the fuel tank to the
engine and will explain what it does how
it works all that and the symptoms have
a product valve that is stuck open
symptoms of valve stuck closed and
vacuum leak hose on purge valve so make
sure to stay until the end that video
gate guys can save you hundreds of
dollars because sometimes when the purge
valve is bad or we have a vacuum leak it
will tell you that let's say maybe you
need oxygen sensor mass airflow sensors
you spend hundreds of dollars and all
you needed was a little hose so make
sure to stay until the end now quick
introduction we'll have more than 200
videos guys on every car we get at the
shop our mission is to save you as much
money as we can so please subscribe to
our channel and like the video let's
start money now and show you what we're
doing here yes this engine ok it's a
4-cylinder guys Dodge Chrysler Jeep and
Fiat engine used in multiple vehicles
but many engines will use the same
concept pretty much is the same thing
BMW Mercedes for Dodge whatever it is
Volkswagen all day all of them have a
purge purge valve product canister valve
what it does now guys you can see this
is your fuel line here usually will be
somewhere by the intake it may be
mounted on the engine it may be you guys
mounted on the actually on the body
somewhere but this line big line this
line brings the vapors guys from the
fuel tank to the purge valve pollute
valve it's activated it just opens and
closes by 12 volt supply the engine
computer tells it ok open and you're
like those vapors go from here past that
hose enter the intake manifold from the
intake manifold they'll end up in the
engine and they will button through the
engine guys what what will happen that
way you reduce emissions you don't let
the fuel vapors go in the atmosphere
second your car gets better
because you get some extra feel that way
instead of losing in Indians fear know
how that how that valve can gain fare
guys stuck open or stuck close and the
third option is guys having a bad house
cat calls from the public valve to the
intake manifold make sure to stay until
the end just that little house for a few
dogs can cost the guys hundreds of
dollars because it will not tell you
that you have a bad valve will explain
that in just a little bit so let me just
remove that in usually guys okay you
have a wire that you need to disconnect
on line two lines usually that you need
to disconnect and you can pull it out
and we will explain okay what it does no
you guys nothing fails stuck open
you guys can develop engine misfire okay
engine misfire you can develop rough
item you can develop guys hard time
starting your engine especially when
it's called why is that no gas because
it when it's that open it will create
vacuum leak you suck extra air from the
fuel tank that it doesn't know of and as
a result guys the engine is confused
he thinks it's getting certain amount
aware but it's getting more air because
you have a vacuum leak and it will put
less fuel because it doesn't know about
that extra air and the car may miss fire
you may guys get a code for Linda
gunning engine Milliken II engine
usually indicates bad guys oxygen sensor
or bad mass airflow sensor you will put
new sensors hundreds of dollars guys and
that's not going to fix your problem it
could be just a bad valve usually when
the valve is bad
he wrote draw a code kb such as p 0 4 4
3 4 4 0 4 4 4 so many calls gas can be
related to project valve depending on if
it's stuck open stack closed but it may
take t 300 miles to get the code now
that's the best in air you get a code
and you know that that guy is good but
if it's stuck close guys okay it's even
better because it doesn't affect so much
the engine but you're going to get a
code that you need to
so off this is the best scenario
the worst one guys having a bet vacuum
hose of your back hose from the patrol
to the intake manifold if that hose is
cracked somewhere but the purge valve is
working okay what's going to happen now
it's going to happen guys you're going
to create a vacuum leak and the engine
would think the polygraph is working
okay but you're still getting that extra
air your engine may misfire may get an
engine light for running lean in meaning
new oxygen sensor for mass airflow
sensor and all you need is a okay is the
hose that is just a few dollars gas and
these guys kid because because of that
house and vacuum leak on your car it
could because from other excuse me other
vacuum leaks as well like these holes
here you have quite a few vacuums on
your car but always guys check the
pocket valve and the hose as well so
hopefully the video will be helpful to
anybody having that problem thank you
