And what if power is the issue. Thats my problem

[@iwishtobetexan6060]

​@@coltonallen672you mean you do not have around 12 volts to your connector?

Thankyou. This helped me test mine which turned out was ok. Time for another rabbit hole with this pos Passat.

[@MAGSHowToVideos]

I’m so glad I was able to help. Thanks for watching and I wish you luck on figuring out the real issue.

[@soundfxasmr]

Great video! Just bought a car, previous owner told me someone scanned the ECU and there was a code "related to the oxygen sensor". Got home, scanned the ECU and the code I got (P0403) is NOT related to the oxygen sensor, but the EGR solenoid. I'll be testing the connector for power and the solenoid to see if it's stuck. Thank you for pointing me into the right direction! PS: That outro music got me head bobbing right now... LMAO.

Thank you, for the blessed presentation. I did these checks on an ‘03 Mazda Tribute with a 3.0 V-6. I noticed no vacuum going to the EGR from the valve. I removed it, supplied power and ground to the EGR valve with a power probe, and no “click” at all (indicating the solenoid is not functioning, as you said). My question is, have you seen many faulty replacement EGR valves? The one I tested seems quite new. Just curious if you have ran across a few duds in your time. Be blessed, be well!

Well after dealing with some leakeage on my golf mk4 I decided to make a smoke test and the smoke was leaking from the EGR valve breather. I cannot tell if this was good or bad so thanks to your video it seems that the EGR valve is faulty. Thank you!

[@simonbertioli4696]

Any advice on testing a 5 pin EGR valve... Many thanks... Simon

[@kobramic]

Thanks for the video! For the good valve, both channels should hold pressure or only the one that goes to EGR? In your video, your testing only that.

[@rubenalmanza5114]

Thank you this demonstration was very good and it helps

[@wazooavenue]

I did the test just like you did. (The connections for the tubes are in line) and when I blew into the top tube, air comes out of the bottom connection. When I blow into the bottom connection it's closed. is this a good Solenoid?

[@Ben-wg6uf]

Thanks man. Been a while and this was a great refresher

[@black2324]

Great video, clear and concise!

[@therealeffingdeal]

Saved my bacon. Thanks and subscribed!

[@AK-ok2jh]

Very good explanation

[@hanzo52]

So the solenoid should be holding pressure when blowing into either port? And have open flow when applied voltage?

[@AK-ok2jh]

Did you checked the voltage of the plug when engine is running? Or just ignotion is on?

[@laapulsford]

Great video, thank you. One question, when the car is not started, but the ignition is on, would you expect to receive 12 volts at the EGR solenoid? I would guess the 12 volts would open the valve and allow vacuum to pass to the EGR valve and open it and thus allow exhaust gases to pass into the inlet stream. I would have thought the introduction of the EGR gases would be dependent on engine temperature and as such the 12 volts would only be present when the computer detected to correct conditions - temp etc.

[@mikecross1402]

either what you said or the the 12 volt signal would be cut off at the time the computer sends the command.

[@NitrosDen]

Thanks for the video. What about a 3 pin egr valve sensor for a 2007 hilux 1kd ftv? This sensor sits on top of the egr valve and is separate to the vacuum sensor.

[@shifty2755]

Thanks for the video. New subscriber

[@eagleabram4016]

Thank you for the educational video. My question is: I think my EGR solenoid is closed at all time because I blow air at one end and no air go through at the other ends even when power applied with click sound. No air at all and tried both ends, same result. Do you agree it is bad? Thank you.

[@MAGSHowToVideos]

So on some valves you can blow air through one side but not the other. The main thing is if power is sent to it does it click? If so you can try sending power through it while applying vacuum pressure through one side and see if you can feel it come out the other side. If so your valve is not bad. If you don’t get vacuum through the valve than it’s bad. Make sure you have proper power/voltage and a good ground before attempting this test. I Hope this helps.

[@larrydresser7731]

Mine gets vacuum then goes down to zero. What's your thoughts on that

[@timothyproksch2915]

Awesome now I can act like I know what I’m doing . Fake it till the a make it .

[@ibneamin3925]

Hi, watching your video in 2024, just a quick question, I checked my car egr solenoid harness and the power was 9.70v . Should I be concerned? I have nissan qashqai dci 2014 with codes P0403 and P0409.

[@MAGSHowToVideos]

@@ibneamin3925 I’ve never worked on Nissans, but yes it should be 12v. With that said, if your vehicles battery is reading 12v, that means somewhere between the battery and the EGR solenoid there’s a voltage drop. Common causes, a burnt/corroded wire, fuse panel or computer.

[@Brendan9300]

very helpful thank you

[@darksolara6750]

Quick question can a VSV properly click when powers applied… But… But the Om readings are below the minimal satisfactory for instance… Mine should be 33 to 36… It reads 30 and 31… Could this still be failing even know it will click when power is applied… Thank you for a response this one's kicking my butt

I'm Trouble-shooting The EGR system on my 2005 Santa Fe 3.5L V6 The EGR Valve Solenoid is in a 'open/Vacuum' position, when not powered. With Power supplied it 'Closes/no Vacuum' The wiring Harness Plug Has power, but the Negative(?) connector side of the Plug seems to not be connect to a Ground Source... My Question is: IS The Negative side of this Harness Plug controlled by the ECU through the ground wire, or is it the Power-wire that is controlled by the ECU?

[@pauloheitorcosta8924]

[@JoyfulJapaneseMaples-us7on]

When you tested it with the power probe, how dis you know which post was positive and which one was negative?

[@igoruhrovic6567]

HI, I think you should edit the video and show how is the meter set.Volts, Ohms or where it should be. Might be obvious to electricians but not to us beginners. Thx

[@stephenpoole9142]

Would this make the car stop working as my audi all of sudden stopped working but once o took the recirculation pipe off for the egr it ran but back pressured throu the small pipe to work? Hope this makes sense

[@Samson-EC]

Great video. How about having to check ohms on the solenoid. Is that needed if you hear click or not when supplying power? If so, what should be reading? Thks ....jc

[@directautofix]

Testing for ohms would not be needed as the click means that it opens and closes properly.

[@Samson-EC]

[@misterbulger]

My egr looks suspiciously clean for failing for Nox could it be that it never opens and essentially deleted itself?

[@persianchris2451]

2:07 - "Ok here we go, we're going to turn the multimeter on...." - Perhaps for your audience, can you please mention what setting you set your multimeter to when you measured 12v vs testing power probe for 12v? Thank you for your video

[@MAGSHowToVideos]

To answer your question the multimeter was placed on DC volts. However, thanks for the input I will try to remember to do that in future videos.

[@FreddysHamster]

If you don't know what setting to have your multimeter on then you probably shouldn't be stripping solenoids off motors. That's the 12v DC testing for beginners video you want.

[@1776FreedomNow]

on a 94 Honda Civic it works differently. when there's no power being sent to the solenoid, the valve is open and air flows through. when power is sent to the solenoid the valve closes not allowing air to go through.

[@larrydresser7731]

That's the way my 94 Nissan HARDBODY is also. I have to supply power pluse hold my finger over the two outlets to get constant vacum

[@piuricricardo5455]

thank you!!!

[@karlburns9234]

What if the one sticking from the side blows easily but the bottom one doesn’t blow threw is it broke or still working ?

[@tomjudge6654]

I've just tested a suspect valve and one port won't allow air through ( which is normal ) but when I blow through the other port air escapes from the small round cover on the back of the valve. When I connect it to a 12v battery it opens and allows air through so I know it's working, but when I blow through and cover the other port, air is still escaping from the back of the valve where a small round cover is.

[@isaaccervantes2462]

Is it normal for you to have Voltage on both wires once you plug it in?

[@pedrorojascervantes3928]

Something to keep in mind is that any electronic solenoid/ actuator can have either a power or ground activated circuit. Applying 12 volts to the wrong terminal can and will fry your computer! Bench test with power on only,NOT on vehicle. See scanner Danner for a short but informative vid.

[@jeffg5576]

My solenoid blows air through si as you said it’s stuck on open position But when I plug it in power it clicks and holds pressure but then when then take it off the power it remains open. Is my solenoid bad? Or Good? :). Thanks for the great video!

[@MAGSHowToVideos]

If it retains pressure when powered on it sounds like it’s still good.

[@bestofgotti17]

I’m late… but what if you blow in one port and no air come out but if you blow in the other port air comes out?

[@posplayr]

The 1990 EVTM describes using a vacuum source. I'm using a dual set of vacuum gauges to monitor what is going on. What I'm using would not be detected with this test.

[@hunterhryciuk3964]

[@oguzkutluay2458]

hi,great work .is it possible to repair the leaking valve?

[@MAGSHowToVideos]

It really all depends on what’s wrong with it. However, if something is wrong with it your best choice is to just replace it. If one part of it has already failed it’s only a matter of time the rest of it fails as well.

[@Tantobuds619]

So what if I have 3 ports? I do get the clicks, now when I blow in one air does comes out of one but not the other but when I supply power then both push air out. Is it still bad. Solenoids are from a 89 ford probe gt I have two solenoids

[@Tantobuds619]

Now I should say one port has a cap on top and the other ports are like the ones you are showing a side one and bottom one.

[@contouraerials]

doesn't matter where positive and negative go from multimeter to solenoid, correct?

[@danbegay3646]

there should be no air leaking out the 3rd port under the cap?

[@FayazShaikh]

What is the resistance value ?

[@MNCPMSteve]

Please explain how recycling exhaust gases back through the intake manifold will make things cooler?😮🤔🤔 Thanks heaps.

[@MAGSHowToVideos]

By recycling some of that hot air mixture back into the engine, there is less going through your exhaust system which allows it a little more time to cool off. Granted it’s not much, but over time I believe it helps extend the life of some of those parts. The main reason for the EGR Solenoid is to help burn off more of the access gas vapors to produce cleaner admissions.

[@shifty2755]

Gases Goes through an egr cooler that's water cooled

[@castnivorechannel7260]

Hi, what size is that air hose? 3 @ 4 @ 5 mm??

[@carnyclyde]

Should both sides hold vacuum? Mine is missing the cap on the end. Bottom hose line hold vacuum. top hose I can blow through. Is this normal?

[@MAGSHowToVideos]

Yes that can be normal the real test that’ll determine weather it’s good or bad is will it work when power is supplied to it. Not sure about the missing cap tho.

[@paulkomn946]

my egr is electrical , no vacum hose. If i put 12 v without dismantling it and don't hear the click does it mean my valve is stuck and need to be replaced?

[@shifty2755]

Or the pintle is jammed with soot

[@altonbailey9702]

So what happens if it’s holding a vacuum on the highest input and when you blow through the lower one it’s letting air out does that mean it’s still partially open or failing somewhere. Because I’m able to make the actuator click but in trying to put air through the solenoid one will Maintain a vacuum and the other won’t

[@MAGSHowToVideos]

Some vacuum valves allow you to blow through one end but not the other. The one I had was designed to be closed in both directions.

[@altonbailey9702]

@@MAGSHowToVideos Ah. One more question. When the EGR valve releases to open, do it do it slowly or instantly. I did a vacuum test and the pump released the air in about 2 seconds.

[@mohsinsiddique4960]

I just took off my solenoid. Air escapes from one of the sides when i blow and when i block the other side. Side does not escape from other side when i try other side and blow. Is my solenoid faulty ?

[@MAGSHowToVideos]

Not necessarily that could be completely normal depending on the type of solenoid you have. Have you performed all of the tests? The main test that will determine if it’s good or not is the power prob test.

[@LeonardoBiaziCabral]

Only 3.79 volts arrive in my car's harness, it's a Golf 1.6 SR, is this normal?

[@MAGSHowToVideos]

I’ve never worked on a Golf 1.6 SR before but 3.79 volts doesn’t sound right. Even if you were testing a 5 volt power signal wire that wouldn’t be enough. Sounds to me like you’re going to have to test your wire hardest to see if you have high resistance.

[@joeh690]

my EGR is not gettiing 12v at the plug, is that normal ? 08 Ford Ranger ?

[@MAGSHowToVideos]

If you have your vehicle running and you don’t have 12V going to the solenoid than something is wrong. The most likely thing would be a bad wire. I would try an locate some sort of wire diagram and trace the wires so you can test for resistance.

Depends on the brand you can’t always rely on the blow test because some are made to be closed and so open. The one I used in the video was a closed module. To truly tell if the solenoid is bad you need to perform all the tests if it passes all of the other tests then it should be good.
