Checking TPS.. where does the vacuum for the throttle opener go?
I'm working on checking the tps on my '94 3.0. The vacuum connection to the throttler opener has been capped off at some point. Can anyone tell me where it's supposed to go? Thanks!

Looking at the vacuum diagram it looks like it goes to the vvt with the other line from the back of the throttle body, but how does it route? Do I need a "T" to connect it?

Checking TPS.
The TPS function is independent of the vacuum system.

Right, I understand that. I just happened to notice that the vacuum line on the throttle opener was capped while I had the throttle body off to check the tps, and I wanted to know if this was ok, and if not.. where does that vacuum line go.
I have photos but my camera is at home and my usb cable is at work...

What is "vacuum line on the throttle opener"? Need either a better written description, or a picture.

Ok, I'm stealing this photo so this is NOT my 4runner. I may have actually answered my question finding this, but I'm still not sure why mine was capped.
What I'm refering to is the throttle opener on the backside of the throttle body. This one isn't capped, but mine is. Since it's vacuum operated I'm assuming mine isn't doing anything. Do I need to re-route my lines to include it?

I would assume that function does not work on your vehicle?
