just leave the wires plugged up, draw vacuum on the purge solenoid and start the engine, bring the rpms up a little and wait until you see the vacuum gauge go down. that means the solenoid does open at intervals. test vacuum lines to insure there's no leaks in them. if there are it can cause your car to run rough at idle in drive. good luck. test the gas tank vent solenoid too if you have trouble putting gas in the tank.
When I'm putting gas in,my 03 jeep liberty sport, it acts like it's full and I have to pump a second then wait & repeat💨 it takes forever. What do I need to check for.?
I havece a honda civic Turbo 1.5 2017 and when is in idle on stop light on drive mode start shaking and the rpms drops to a 550 rpm but if I turn the ac or day lights on it goes back to normal 650 rmps. You think it can be a bad purge solenoid?
@@cavalierabouhamma2828 the valve needs to be closed so your able to apply vacum(suction) to it and see if it will hold the vacum. That's all vacum is, your applying suction to something to see if it can pull air through what ever your testing. If your gage pumps up and slowly goes down, then you know you have a leak. You just have to figure out which way your valve works.
so I got a P2450 code on my new Porsche 992 ... I think on a couple of occasions I might have "topped off" the gas tank and cause issues... what do you know about 2450?
Scanner danner would have described it correctly, no current flow no voltage drop that's why you have 12v and 12v on both sides of the coil. When it's active 12v and 0v on the two because there is current flow and a voltage drop.
I didn’t use a fuse. 16 gauge wire connected straight to one terminal blade and another 16 gauge wire to the other terminal blade on solenoid and then straight 12.6 battery voltage. All the magic smoke came out.Did this off vehicle,bench test so as not to mess up ecm/pcm. Solenoid showed 32 ohms of resistance and obviously continuity. Assumed it was a bad solenoid, so what the heck.Do need something to bring amps down. Remember,it’s not the voltage it’s the amps that smoke components 😖
Are there Purge valves that are designed to stay open until you apply voltage. Another words the other way around where applying voltage closes the valve?
Replaced my Evap purge solenoid today in My Camry. All the symptoms of rough running engine and misfires immediately went away but I cannot get the computer error light to disappear when I disconnect my battery. Any Ideas people?
after unplug,, the service light comes back on mine. but,, i erased code,,, found+ fixed tore hose. its running better now and less fuel. hopefully it stays off.🏁🏁
Symptons,,,are smell fuel at RED light,,,short stutter during take off ,,,while putting gas does not flow easly,,,if charcoal is maxed out in the canister in the back in front of the spare tire
true. the hose was bad on mine. i should if did further testing but didnt. i replaced hose. + erased code with obd2 . i think i should be good. if so,, i fixed it for price of a 2 cent piece of rubber hose.👍🏁🏁
I’m getting P0441 and P0455 (large leak) codes, which lead me to the evap purge solenoid on my 2009 Camry. When I did a visual check w/ the engine running I hear a hissing noise. Would this likely be a bad hose or could it be the solenoid unit?
The worst I ever saw. Use the Right terms Man geeez. LED Light is computer safe LOL. A LED tester Light takes Less Voltage to Light then a Reg. Test Light, Because a reg test Light has more resistance then a LED Light do your Home Work ....... Just because you hear Clicking dose not mean the Gate is Closing all the way inside the Valve It only means the Coil is energizing.
Still all the videos you guys can talk and I got all that but I need to see what can somebody show me a clear picture and It doesn't help me at all when I can't see what the h*** you're doing cause it's another video it's going to be pretty watch those cause you can't see what you do and so it's stupid
Hook your bicycle pump to the hose and see if is holds then energized with your batery to release.
Thank you very much for the clarity!

@@jenntitman35 any codes? if not. look for loose of worn hoses. sounds like solenoid sticking but not sure+ needs further checking.

This is extremely confusing. Keep it simple man. I don't need twenty ways to check it. Give me one. The simplest one.
Just hook vacum pump on it and see if it holds, or blow through it. If you can it's bad.

Does this thing cause your car to jerk like crazy and lose acceleration??
Yes it does
@@stephsawakening528 Does it make it don't start no crank?
normally the electrical does not fail, the seat seal or plunger gets worn & either sticks or does not seal completely allowing slow leakage
Good explanation
Just because it's got power don't mean the solenoid is working. Check or then Pull it and add power and check flow. That's the only way.
Excellent description. Thank you.
What if you change that part with a new one bc autozone sed thats what wrong but its steal doing the same thing
Could a defective purge solenoid keep you from refueling your car causing the pump to keep shutting off?
Yes Nigel is correct
No
Is it supposed to make a loud fast click click click noise

32 ohms is correct. its a coil! when amps go through it makes the coil turn into magnet. that magnet pushes the valve open/close.
mine went bad and was reading 135k ohms. also a good one clicks when you start the car cold.
Scannerdanner all over, down to the T-pin.
Are there Purge valves that are designed to stay open until you apply voltage. Another words the other way around where applying voltage closes the valve?
The vent valve stays open until voltage is applied. The purge valve is closed until voltage is applied.
@@steve4386 I have to purge valves and they seem to be functioning the other way around. Allows air through until voltage is applied.
Difference between p0946 and a p0947 code?...says high and low online but idk the difference?
Just change the purge valve they're cheap and very easy to change. Minethrough a code and was making a horrible ticking noise
excellent video thanks

D Manns sounds like vacuum leak. Use spray bottle of water around suspect hose to find leak, or have someone use evap smoke machine to find leak
Vac leak SOMEWHERE CHECK GET REGULATOR NEXT TO THE GET LEFT SIDE LOOKING AT THE FIREWALL WENT THEY GO BAD THEY HISS,THE sealGETS DRY ON THE BOTTOM.
What about P0442?
What about PO442?
Great video very helpful
great video thanks
N hi
Liter a la
I rplaced mine on a 2001 Cherokee and if the engine backfires the top of the valve will pop off. Is that normal?
You vac lines are BACKWARDS or canister is MAX capacity,time to buy a new one $$185 ××>375.00 toyota,S are less
anybody .
knows where is the vape canister solenoid locaed on a ford flex 2011 Thanks
Thank you
P0446?
On a vehicle this old, time to delete that shit. You’ll get a few more years out of it.

Useless video on UA-cam. Keep it simple straight to the point on how to test the purge valve
those hosed are brittle.i wish they were made stronger on my car. po446.was my code#)
