i'm a noob at engines so i have a question to ask.
i'm inspecting my TPS sensor to make sure that the resistance is on the right spot. but in the toyota factory service manual, it says that i need to use a vacuum on the throttle, just what is that vacuum? thanks!

 

Vacuum is created by the intake... but I am not really sure as to your question.

This is a great article on the TPS and adjustment:

thanks, this will be very helpful, well on the FSM manual, the first step in inspecting the TPS sensor is "apply a vacuum to the throttle." if that helps.

 

Probly the dashpot that slows the closing of the throttle.If you're checking the TPS then you need it at the fully closed position.

alright thanks, am i able to adjust the TPS while it is removed from the engine?

 

THE STIG is your name from top gear if so you rule

 

LOL, i freakin love that show!!!!

 

Yes, but it needs to be attached to the throttle body to do so.

 

so that means that i am able to work with the Throttle body while it is removed from the engine.

 

Yes, as pictured on the web page posted earlier:

 

alright, thanks, this will make life much easier for me.

 

Yeah, the 3vze has like NO room to get at the TPS bolts when the throttle body is installed.

Pull it off and bench test it. You can also clean out all the gunk build up.

 

agreed, it's practically located at the worst spot possible. well hope to get some work done this weekend. thanks.

 

I've just got finished with adjusting the TPS Sensor, and now it runs great, this is a little off topic but, anybody know how to increase fuel mileage?

 

i bought a diesel lol

 

Yup, put a 2x4 under the gas pedal.....
