Carbon Cansiter question?

james_se-r · 09-19-2004, 03:04 PM

I need to know where the vacum line that comes out of the bottom of the carbon canister goes on a 1991 nissan sentra se-r. Mine looks like it was pinched/ worn through/ or cut by something. Also the is a ground wire, grounded to the frame right next the carbon canister that also looks as if it was cut, Im not sure what this is a ground for and where it goes. any comments or help is greatly appreciated......

All three lines from the canister plugs under the throttle body.

This is the ground for the tranny. Look at your tranny right on top of the driver side axle.

what do you mean by plugs under the throttle body? There is only one line that come out of the bottom of the canister, does it plug into the throttle body??? Hope I dont have my vacume lines crossed up???

The ground wire, specifically is for the starter i beleive (since the starter grounds to itself...).

My carbon canister's lower hose is connected to nothing.
It is sord of like a vent.

No, Steve's right. During my engine swap last week I noticed the same wire just hanging around and sure enough just as Steve had hold me there was a connector on my tranny with a wire missing from it.

Yes i know...since the starter grounds to itself, and gets bolted to the tranny...i beleive that wire grounds the transmission for the starter.

thanks on the ground wire question. but Im still stumped on the canister thing. I cant see anything near it that it looks like it plugs into, is it suppose to be a vent like scortch99th said?

I know one of the hoses went to a vacuum plug down below the brake booster on my 92 SER. The others went to the manifold like nismo said.
