Has anyone ever wondered if the solenoid on the charcoal canister works? I took the opportunity to post up some pictures so that anyone can reference to. These pictures and info comes directly out of a GM 1986 Camaro Shop Manual.

Very interesting. Way to think outside the box. Good job.

 

 

awesome ! thank you

 

Your welcome.

 

i love post's like this . thanks , i constantly ck. small items like this . good post .

 

:-)

 

This stuff is gold!!, exactly what I was looking for. I wonder if it would be different kind of testing for the later models' canister/solenoid style...

 

I have the testing for the years of 86, 87, 88, 89, & 90. If you need other years, let me know. I'll posit them up.

 

I dont have one any more

 

Lucky. Lol

 

This is great. I was looking for the configuration to hook my system back up to get rid of the fuel vapor smell after shutting off the vehicle and reduce fuel tank pressure. Sunday project at the Acura dealership. Good thing I have free access to the shop.

 

Can you post for 88 5.0 TPI??
Thanks in advance!

 

sure. let me extract the pages from my manual. Itll take a bit, but ill get it up.

1988 5.0 & 5.7 TPI EECS (Evaporative Emission Control System) testing. Vins "F" & "8"

Thanks so much, I just posted a thread few days ago about that without any responses, so that really helped.

 

Your welcome man. Have a good one.

 

Thanks, by the way, I was wondering if you know anything about the AIR inlet on the top of the canister, mine has a cap on it and I was wondering if it should be open or kept close with the cap...?

 

Please send me the information for 1989 Trans Am GTA 5.7 automatic, just to make sure I set everything up correctly.
Thanks,
Josh Jacob

 

There should be a hose there. Check out this post that I made. It'll describe the vaccum lines for you. Just search for the one that corresponds to your engine.

I gotcha man. Let me finish eating dinner and ill get back at ya.

 

Okay man, here is your setup, which is the same as above, except for the ventilation valve. Your vent valve should be on the cap while the earlier years have the venting valve on a hose which is connected to the sending unit.

I looked at the diagrams, and it seems that the inlet that I mentioned its just a vent with no line attached to it, the question is if it should have a cap on it or not? mine has a cap on it but I'm not sure if its should stay on...

 

Now you got me curious. Take a picture man. I wanna see what you got.

 

Its that thing on the left...

 

I think that cap gets removed and a U hose connects from there to the other fitting next to it. But I could be wrong. I don't know. Google it. Type in evap, the year, and engine and hope fully you'll get a good picture.

 

I didn't see anything, and even on the diagram it shows it but nothing connected to it, the only question is if the cap should stay off or on...I cannot seem to get someone that knows something about it

 

Here you go. 88 IROC. http://s19.postimage.org/tfryj4uz7/canister.jpg

 

Interesting, but it looks like different canister than what I have and this one says "Fuel Tank" next to the inlet and not "Air Vent" like mine. Please look at the picture I posted you will see its different canister and look at the diagram you posted, the inlet is #5.

 

Let me get off the iPhone and get on the laptop. How long have you had the vehicle?

 

looks like you got yourself an after market. but I really dont know. There where quite a few different types of canisters.

 

so its this one you got tight??? With the cap that you mentioned.

 

Okay man. Disregard the PM's I sent you. I went to a very good site about TPI systems (Chevythunder.com) and I found this on that site. This is your TPI setup with the vacuum line diagram. Now you know what and how it is routed. As for the cap, I assume that a little foam filter goes there. Ive never seen one though so perhaps if you copy the picture and make a new thread in the General Engine board, someone can help verify what you may be missing.....

 

Good luck 88I-ROC

 

Thanks man, I appritiate your help.

 

Thanks. I really appreciate it. Now I just have to wait till tomorrow and order the new fuel cap from GM and then reinstall the evap canister. Again, I really appreciate it.

 

Your welcome guys.

 

Hey akanitro, maybe you know something about the inlet vent with the cap that is on top of the canister?? you should have the same canister as I am
