Tps install

[eran tomer]

I need to install a new tps. Books say to put it on the shaft and turn it counter cc.
to do so it has to srart from this point, and it doesn’t seem happy to turn.
Youtubes show the opposite direction. I guess the books are wrong?

That seems wrong to me and too to extreme. Basically look inside of it and think about which direction the throttle shaft will need to turn the tps inside components. The throttle shaft is somewhat flat at that point. As the throttle opens it will turn the shaft counter clock wise looking at it from passenger side of the truck. So the upper tooth needs to be behind the flat of the shaft and the lower tooth needs to be just in front of the shaft. The way you have it will bust the TPS!

What year is your truck? On my 99 vortec 5.7,it wasn't difficult at all to change the throttle position sensor. It can't go on but one way. TBI engines are different, but I didn't think the TPS was that difficult on them. But I could be wrong, it does happen.....

it's 95. yes, the books must be wrong.

OK then you're dealing with a TBI engine. The only one I've had, I never had to replace it.
There's several TBI guys on here who should be able to help. Good luck!

Did you get it? Did you adjust it after install?

 

[eran tomer]

didn't install it yet. how do you adjust it?

 

[TagAllen]

You need a volt meter and have to loosen the mount screws. Then depending on its output voltage you turn it one direction or another. Most have very little to no adjustment though. such as the one you pictured would not move much at all.

Check it with the engine turned off but the key in the on position.

I used this to check the voltage versus splicing/stripping wires.

Then i took it off after getting the tps set.

If you need I believe I can find you a part number for a adjustable TPS. But only buy it if yours wont go into range.

Dont quote me on this cuz its been awhile since I replaced mine but Im pretty sure that is wrong.
The tps goes on so its alignment hole is below the hole in the throttle body then you rotate it clockwise untill it aligns.
You should feel the spring tension as you rotate it.
With the throttle plates closed, line up the notch in the tps so that you have to turn it up for the holes to match.
Shouldnt have to turn it very far and it shouldnt feel like it is binding.
Just some spring tension.
And when you release it it should go back to where you started.
Mines a 94 but Im pretty sure its the same.
Let me know if that works
