How To Test a EGR Valve Solenoid 

😂😂😂😂 Too True!!!

That's all it is just like every government regulation

And what if power is the issue. Thats my problem

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

I’m so glad I could help. Thanks for watching

I’m so glad to hear I was able to help. Thank you for watching.

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

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

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.

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

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.

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.

If that ends up fixing the issue please let everyone know here in the comments. I’m sure it’ll help others in the future. Thanks for watching.

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

@@directautofix got it..thks.jc

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.

@@MAGSHowToVideos Thank you for your interest.

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

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.

@@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.

Signs your EGR valve is starting to go bad is reduced engine performance, rough idling, engine knocking, fuel smell inside vehicle and engine warning lights. Any of these things can mean you have a bad EGR. A faulty EGR valve affects engine performance by creating rough and jerky accelerations. It also reduces engine power, which is noticeable during low and high speeds. The problem is usually more noticeable at low speeds when the valve is stuck open and more apparent at high speeds when the valve is stuck closed. In worse cases, it can cause the engine to shut off while driving.

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.

Or the pintle is jammed with soot

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

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.

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.

Gases Goes through an egr cooler that's water cooled

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.

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.

To be honest I don’t remember what size I used. It was so long ago when I filmed these. All I did was take the EGR Valve and found a hose that fit.

ur looking at the charcoal canister purge valve thats why

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.

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.

Is the .06 volts coming from the wire hardness that plugs into the solenoid?

@@MAGSHowToVideos yes

If your B1s1 is defective does this effect this EGR selenion or not?

Mine does the same thing did you figure it out ?

​@@timothyproksch2915I ended up using the old one, but I put the new electrical switch part on it. So I Frankensteined it. LOL Buying cheap parts, sometimes makes things more difficult to fix.

Sounds like it’s most likely broken and needs to be replaced.

I have disconnected the vacuum pipe that comes from solenoid im not getting any vacuum

Does it actuate when you send power through it?

Because it held vacuum on the first pipe he tried. It would be pointless.

He could have tested both to see the difference he got 2 working and not than us we need to buy and test wat happens wen both are holding air

We're is the fuse location

Might be ecu controlled. No fuse

I mean does the solenoid open and close. If not there’s something wrong with it.

@@MAGSHowToVideos a solenoid is just a helical coil of wire and it's not supposed to be movable. But it controls a valve and the valve is supposed to be movable
