Solenoids on 2g CLicking (pics)

Im reffering to the 2 solenoids with the white and yellow arrows.


Taken from http://members.shaw.ca/dsm.1000q/Engineprimer/2G/solenoids.htm:

"When you are facing the engine bay, the left-most solenoid is the exhaust gas recirculation (EGR) control solenoid. It is indicated by the white arrow. It controls the flow of exhaust gas through the exhaust gas recirculation valve - a valve that allows some exhaust gases to run back into the intake stream. This is purely for emissions purposes, as "reburning" some of the exhaust gas helps reduce emissions.

The first solenoid, marked with a yellow arrow, is the purge control solenoid valve. It controls an air connection between the evaporative emissions charcoal cannister and the intake system. The charcoal cannister is designed to absorb fuel vapours that come from the fuel tank for emissions purposes. The purge solenoid allows the ECU to connect the cannister to the engine intake - when connected, the gasoline vapours are drawn in to the engine and burned off. The solenoid is there so that the outlet from the cannister may be closed when the car is not running. "



My purge control solenoid is clicking! All my vaccume hoses are hooked up properly.
Do i have a faulty solenoid? As soon as i unplug it the ticking goes away. They chatter when you tuch them.

Also, I also hear ticking elsewhere around the intake manifold area. Is there another solenoid hiding somewhere?


All sugestions welcome

Its normal. Mine clicks usually in the cold mornings. When the car is fully hot, the clicking stops. I thought it was a problem as well. I bought another one and it still clicks. Just ignore it.

really?

man that is not the answer i wanted to hear.

There MUST be a reason why this is happeneing and more importantly how to fix it

Yes.

They're ten years old. Replace them.

There's that batch of solenoids in the fuel injectors....

Use a piece of vacuum line between your ear and the clicking area. Move it around until you hear where it is.

I guess i should go ahead and buy them new right?
I mean, do you think ill have luck with replacements from the junkyard?

 

[GSX20]

Any solenoids you get from a junkyard will be at least 6 yrs. old. Just buy new ones.

 

[Alex_95TSI]

Yup thats what i figured

Mitsu dealer here i come! Hope these damn things arent too expensive.

If you dont mind having your cel on just find that writeup about the vac lines removal and get rid of all those solenoids, Ya the cel will come on but it will save you from buying new ones.

That wont fly here in Ca my friend.

Ca smog is a huge huge PIA!!
At least i have awd so its not so much of a pain. Stick it in my tail pipe only please!

 

[Tarantula]

its nothing serious. Don't worry about them. Its a federal thing anyway. No real performance will be given by replacement. Spend that money on a mod. Thats my opinion. Like I said, mine does it when its cold and most of the time its hot while i'm driving it !

sorry slightly off topic but... i did the leak down test on my car and air is leaking around the throttle body...i thought it was the 2 gaskets so i replaced them ....wheew was that a bi***.... did the leak test again and it was still leaking out of that area again.... i have it narrowed down to 2 places neither of which i can feel a leak.... the "psssssss" changes when i hit the little throttle flapper open... the 2 places are the intake manifold gasket orrr something around the solonid but i have no clue about the solinoid...could or does air leak from there if its compressed into the pipes? thanks in advance

The ticking you hear is normal, and buying new solenoids will most likely not fix it. Mine tick when it is cold outside and I replaced them and they still tick. You have to learn to just deal with it. (the ticking gives you an idea that they are working properly because all they are are little check valves that are operated by the ECU.)

This might be the thread I've been searching for.

I just replaced my lifters with the revised version, and thought this would rid my car of the infamous tick. Unfortunately it did not get rid of the recent tick my car has developed. The tick isn't THAT loud, but when a car is right next to me at a light, it is very audible.

Next time I get a chance, I will check to see if this is indeed the the culprit.

**UPDATE

I went ahead and replaced it with one from Rancho Cordova and it actually solved the problem. I no longer get that annoying ticking noise at all.
