Codes p0440 and P0446. Fixing

Don't know if there is a difference on the systems 4 cylinder v.s. 6 cylinder? I have a 3.4l and from what I see, there are 3 VSV solenoids on mine. 2 under hood and one at canister behind gas tank. I checked the 2 under hood. The one on top had a good clicking sound with 9 volt battery. The one below...all I could hear was the sparking with wire touching 9 volt battery. My question is, should all VSV solenoids make the clicking sound? If so, I think I found my issue for the p0446 code. The VSV (evap) solenoid.

 

Yes you should hear the vsv actuate. If I remember correctly, you should be able to find a replacement. I was able to find an OEM replacement for my vsv for evap that went bad. No problem with codes since then.

 

I see them on ebay...Thank you GHS57!

 

J have had do exactly same thing and still same problem

 

Check to make sure the clamps on your hoses are tight... don't ask why Im saying that lol...

 

I checked them, but I believe you agree with me this clámps are like you can’t tight them, unless I replace them for those little ones that have the little screw so I can tight them.
THANKS FOR YOUR REPLY by the ways I always read you guys are very helpful

 

Yea I replaced mine with one of those screw on ones and apperently it was not clamping well... expensive fix lol
