I have a problem trying to pass smog. I pulled the code p0466 which i found out is a clogged canister vent solenoid. I have a 01' blazer 4 dr, 4x4,. i had check the vent solenoid that is next to the spare and had a little dust but nothing major tried my best to blow it all out checked lines coming from charcoal canister all clear again blew some air in cannister and a lot of dust came out. btw i had lost gas cap for a week it has been replaced since Is there something i am missing or is there a way to test the vent solenoid? Could it be something with the gas tank?

 

Possible helps

WoW thanks again this is some great info i will start doing a deeper inveatigation today after work. And pick up a vacuum at the auto shop on my way. I have suspicion it might do something with my fuel pump because my gauge is always empty but that could be a whole other reason.

 

Well after a hard time finding a vacuum and after all my diag. I found my vent solenoid was no good replaced it clear code and driven 100 miles code as not been seen since. Thanks for the helpull advice your great

 

No.. thank YOU! The best way to learn to fish is to ask in such a way that it's apparent you just want pertinent info in order to fish.
The worst way to learn is to ask for the fish to be handed to you.

It's a win-win. I assemble knowledge on the fail, meaning I learn, too. And you get more confidence in your own troubleshooting abilities.

And neither of us chances coming out looking dumb.
