3vze TPS install and adjust question

Hi All,

I want to make sure I have my new TPS installed correctly. The FSM instruction seem a little vague to me. It says to check the that there is no continuity up to a certain point in the clockwise rotation of the sensor. I tried to do this with the engine off and had no luck getting a continuity signal from my meter.

Does the engine have to be running to set the TPS properly? Here is a link the FSM I am working with... http://personal.utulsa.edu/~nathan-b...34throttle.pdf

thanks for the help.

Engine doesn't need to be running to set the TPS properly. Are you sure your leads are properly connected to the pins in the TPS? You should only be checking stuff between those 4 points, as per the FSM. If certain values are not as spec'd, you can rotate the TPS clockwise or counter on the little screws.

Most people find it easiest to take the whole throttle body off the truck to do this. Then you have much more room to work. If you do, you may want to have a new throttle body/intake plenum gasket for reassembly. It also helps to drain some (2L) coolant before you disconnect things.

Hope that helps.

Same.
I'm wanting to adjust my tps. I have my throttle body on the table right now. I just need to know step by step how to do it.

Where do I put the meter settings to? 2000k or 200k?

I don't even understand this meter.

First off, to check vacuum you need to have the throttle body installed and the engine running. Dont get confused with user comments to user questions and FSM manual instructions.

Once you have checked the vacuum with a tachometer (i think you need a tach) then you can just loosen the screws at the TPS with a bent screw driver (engine off) and connect the ohm meter per the FSM to the proper leads with the connector disconnected and the screws loose enough to rotate the TPS. I did this to mine and it runs ok. I was never satisfied with how its positioned and I need to take the TB off the truck and do it right but I just didn't have time. You will be able to tell if its not adjusted properly...you will notice it in the gas pedal and when trying to hold a steady speed.

When connecting VTA-E2, I'm allowed between 200-800 ohms with the throttle fully closed.
Would I get the most benefits (better throttle response, etc.) out of setting the tps at 750-800ohms?
And what does that look like on an Ohm meter?

Now another website does not say to adjust with the throttle fully closed. This one says with VTA-E2 @ 0.50mm I'm allowed 0.47K - 6.1K.
Would I get the best results putting that setting near 0.47K or 6.1K?
and what would that look like on an the meter set at 2000 ohms?

Whenever there is a "range" for spec, right smack in the middle is usually the best setting

Don't try to "set" the resistance. What you're adjusting is just a switch. Technically, it is either "on" (zero ohms) or "off" (infinite ohms). But since two pieces of metal (the switch) in gentle contact will still have some resistance, the manual is allowing anything less than 2.3k ohms is "on," otherwise it's "off". And it's supposed to be "on" at .57mm or less, and "off" otherwise.

That's all there is to it. You can't fine tune the resistance, and it has no effect on performance.
